12:33 AM IchGucksLive: Good morning from Climate ofensive germany
12:35 AM IchGucksLive: no log for today
12:38 AM IchGucksLive: covfefe needs to be trunslated added to spelling languages BABEL
12:38 AM IchGucksLive: thanks to the delayed logger ;-)
12:38 AM IchGucksLive: cool objects on thingverse -> https://www.thingiverse.com/thing:2034585/#files Teelight
12:40 AM IchGucksLive: have a nice nonbitbreaking day
12:54 AM LeelooMinai: Heh: http://www.cnn.com/2017/05/31/us/worlds-largest-airplane-rolled-out-paul-allen/index.html
01:00 AM Crom: aviator cap almost done... stole a buckle off a stirup. leaving the ear covers for another day if ever on that one
01:13 AM Crom: http://picpaste.com/1496295290694-1830118809.jpg
01:18 AM Crom: the shelf behind with the glass jars, the front is a piece of wine barrel stave as are the shelf braces
01:20 AM Crom: the dowels holding the the wig heads are bramches off my olive tree that was cut down
01:21 AM Crom: yes they are male wig heads (bit bigger closer to real life girl heads)
01:25 AM * archivist wonders why people dont rotate images
01:26 AM Crom: cuz it doesn't let me
01:26 AM LeelooMinai: archivist: Click the pic:)
01:26 AM Crom: really a feature they need to add
01:27 AM archivist: LeelooMinai, it should just work without me clicking
01:28 AM archivist: my browser takes no notice of orientation info in an image
01:29 AM Crom: yes I need to do the weekly cleaning of my tea cup
01:31 AM Crom: now to do my aviator cap and finish my wifes
01:31 AM Crom: not the one on the wig head
02:21 AM Deejay: moin
02:31 AM gloops: can i install linuxcnc on a usb drive, like will it run from a usb?
02:47 AM Crom: Morning Deejay
02:47 AM Crom: gloops: it should
02:49 AM Crom: ok got the basics of the Aviator caps for my wife and I done. Now I have to get buckets, snaps, and plan on where the ear covers go
02:49 AM Crom: buckles
02:50 AM Crom: FIrst one I did for a production of ' A midsummers nights dream'http://picpaste.com/1496295290694-1830118809.jpg
03:03 AM TurBoss: morning
04:31 AM JesusAlos: morning
05:24 AM MrSun: hmm is there any way to make a parport not turn on and off signals etc while booting the computer? :/
05:32 AM archivist_herron: I think that is something you do in hardware or turn on sequence
07:22 AM MrSun: ough had an error where motors wouldnt move or move very strange ... well found the error .. bob output over 0.45V when low ... so started checking voltages and aparently my +5V put out 7.8V ... changed to a more stabalized setup and got the +5V to be +5V now im at 0.2V when low ...
07:22 AM MrSun: and everything works
07:23 AM MrSun: archivist_herron: well it sucks as i want an output from the computer to turn on the VFD and the voltage sources for the drivers
07:23 AM MrSun: but atm it turns them on .. then off again at boot
07:27 AM archivist_herron: dont switch the vfd etc on before the computer is up
07:29 AM jdh: mine did that also. don't remember how or if I fixed it. spindle would briefly spin up during boot
07:30 AM XXCoder: add switch to setup so can easily power on after computer is booted and ready
07:31 AM jdh: takes another pin. prob already short pins if using pport
07:32 AM XXCoder: the switch? nah its connected to PSUs seperately so no pins needed
07:36 AM MrSun: thinking of doing a series thingie, a switch that needs to be pressed before you can enable power from linuxcnc
07:36 AM MrSun: requires a relay for hold circuit tho
08:00 AM JT-Mobile: morning
08:27 AM Deejay: re
09:03 AM IchGucksLive: hi
09:05 AM IchGucksLive: MrSun: lots of logic at your side ;-)
09:08 AM IchGucksLive: hi JesusAlos
09:08 AM JesusAlos: hi
09:08 AM JesusAlos: How are you?
09:08 AM IchGucksLive: im fine just back from a 3hour forest trip
09:08 AM IchGucksLive: the new servo systems from Japan are getting flowing to germany
09:09 AM IchGucksLive: LICHUAN closed Loop
09:10 AM nos: Anybody know what the status of G71 etc. roughin cycles is in LCNC?
09:11 AM IchGucksLive: its inside 2.8
09:11 AM nos: \o/
09:11 AM nos: so I compile...
09:12 AM IchGucksLive: on the lathe side i guess
09:16 AM nos: I'll be super lucky if this works! \o/
09:18 AM IchGucksLive: nos: https://forum.linuxcnc.org/forum/20-g-code/27040-g71-g70-cycle-for-lathes-first-tests
09:20 AM IchGucksLive: G71 RAR http://www.cnc-club.ru/forum/download/file.php?id=96508&sid=0d10cb83da3b0ca56eb2d1e8750792a3
09:20 AM IchGucksLive: [RS274NGC]
09:20 AM IchGucksLive: REMAP=G71.2 modalgroup=1 argspec=PQDKifjslt py=g712
09:21 AM IchGucksLive: https://www.youtube.com/watch?v=qDyOuob4CTM
09:21 AM IchGucksLive: nos ask andy
09:24 AM IchGucksLive: https://github.com/nkp2169/G71
09:32 AM nos: hm...
09:34 AM JT-Mobile: I don't see G71 in the documents...
09:35 AM JT-Mobile: ah I see it is a branch Andy did about 5 months ago
09:35 AM JT-Mobile: http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=shortlog;h=refs/heads/BenPotter/G71
09:37 AM nos: https://github.com/LinuxCNC/linuxcnc/tree/andypugh/g71type2remap
09:37 AM JT-Mobile: yea that's the other one I saw
09:39 AM nos: hmm
09:43 AM nos: I'm actually doing a programming exercise for a Mazak lathe with like, 100 axii, and trying to simulate so I can spot any huge errors.
09:44 AM nos: It takes a preamble of 14 blocks, just so one can use it safely.
09:50 AM nos: Got into a stupid debate with my teacher about radius compensation, and the guy isn't exactly socially graceful, so he ended up saying stuff which seems to simply be untrue. I have to double-check a bunch of stuff since his idea of having a debate is bringing up a any tangent which he thinks he is right about without regard to what the subject matter is...
09:51 AM nos: e.g. he says I can't get a surface roughness of 1.6 with a CNMG and have to use a DNMG too, even though last month I did it with a CNMG 500 times.
09:52 AM nos: When I pointed it out to him he said the sufrace roughness wasn't 1.6, even though it was actually better.
09:55 AM nos: He also said I can't make a CNMG last 1000 parts unless I use a DNMG for finishing... Which makes no sense to me. I could just as well use a part counter and switch to another CNMG after a set number of parts.
09:55 AM archivist: tell him measure roughness dont guess :)
09:56 AM nos: At this point he was telling me that I get upset too easily.
09:57 AM nos: I don't think he has any regard for what is right, as long as he comes out on top.
09:57 AM archivist: some "teachers" expect you to believe all the crap they come out with
09:58 AM nos: He was talling me that when I use G42 in a closed loop path, like a manually programmed roughing cycle, the machine automatically switches its handedness.
09:59 AM _methods: those who can, do
10:00 AM _methods: you know where those who can't end up
10:00 AM nos: I eventually figured out what was wrong with my program, without, or should I say in spite of his help. I was simply getting thrown off because facing stock is a movement in the 'opposite' direction of OD turning.
10:01 AM archivist: _methods, I came out with that expression earlier today when someone was spouting about some web designer who was teaching web design
10:01 AM archivist: used pagespeed to compare his to mine :)
10:03 AM nos: Sorry for venting! Just, he actually got under my skin this time...
10:03 AM _methods: i don't blame you not sure why anyone would HAVE to use a dnmg
10:04 AM _methods: nothing wrong with finish passes using whatever you want as long as the part is to spec
10:04 AM nos: Apparently, if you don't have good chip breaking, the DNMG has more clearance to keep them from rubbing against the part.
10:04 AM _methods: there are all kinds of reasons to use a dnmg
10:05 AM archivist: rubbing can be similar to burnishing, we burnish clock pivots to a mirror finish
10:06 AM nos: I built a super ghetto burnishing tool for a manual lathe last year. :)
10:06 AM nos: Kept the piece I made.
10:07 AM archivist: just need to use a bit of hss to make a simple burnisher
10:07 AM nos: It worked very well, but wouldn't have worked for long. The ball bearing I used was actually growing in OD from the forces.
10:07 AM archivist: the clever bit is how you rub it on some wet and dry to get a grain
10:08 AM archivist: use a bit of lube to reduce pickup
10:08 AM nos: Right, I seem to remember that. They would make special burnishing 'files' like that.
10:09 AM archivist: clockmakers buy "pivot files"
10:09 AM nos: The grooves were supposed to make the surface look like a tiny lapping plate.
10:09 AM nos: them, yes
10:10 AM archivist: sill expensive for what they are though
10:10 AM nos: yup...
11:12 AM JT-Mobile: hmm just ate breakfast at a golden corral for the first time rain set in so we ate lunch and dinner too...
11:23 AM -!- #linuxcnc mode set to +v by ChanServ
12:11 PM Crom: JT-Mobile: now that's funny...
12:12 PM LeelooMinai_: I would take a rain check for the next day.
12:16 PM * LeelooMinai_ opens some solenoid valve package from China and inside are instructions that begin with big "My Dear" at the top
12:16 PM LeelooMinai_ is now known as LeelooMinai
12:21 PM IchGucksLive: hi
12:21 PM TurBoss: hello
12:22 PM IchGucksLive: so tommorow is the day of truth all 12 mashines are goinioe run at the same time
12:22 PM TurBoss: :O
12:22 PM IchGucksLive: with no testrun from mounting by students
12:22 PM IchGucksLive: i think they not gone make it all
12:24 PM IchGucksLive: schools principal asked me if they have had the same drawings as the mashine in today lookes different
12:24 PM IchGucksLive: as you may know mashines can be mounted differnt mirrorstyle
12:25 PM IchGucksLive: we will see
12:26 PM IchGucksLive: nos still on
12:27 PM IchGucksLive: i decided to go for that part to see if the mashine run
12:27 PM IchGucksLive: https://www.thingiverse.com/thing:2034585
12:27 PM IchGucksLive: and the students can go home with somthing cool
12:28 PM TurBoss: nice
12:53 PM nos: here I am! \o/
12:56 PM IchGucksLive: <- Smiles
12:56 PM IchGucksLive: i read the logs and you got in trouble with CNC teatcher as i am
12:56 PM IchGucksLive: 1
12:56 PM IchGucksLive: yeah hobbyists and G41 is a never ending strorry
12:57 PM IchGucksLive: nos for a prove the last vid of my serias is -> https://www.youtube.com/watch?v=BKUAdACMQSI
12:59 PM nos: I have a lot of respect for my other teachers...
12:59 PM IchGucksLive: thanks beside im not your
01:00 PM LeelooMinai: Hmm, watching some welding video and the instructor says MIG = Mechanized Inert Gas Welding... On Wiki I read it's Metal, Intert Gas, so which is correct?
01:01 PM IchGucksLive: LeelooMinai: the one you like most
01:01 PM IchGucksLive: MIG is printed on the welder
01:01 PM IchGucksLive: if it is MAG its not MIG
01:02 PM nos: It's not Mechanized...
01:02 PM LeelooMinai: IchGucksLive: Meh, I like to know correct terms when I read about new things - so I don't get something wrong stuck in my head:/
01:02 PM IchGucksLive: then best is to read DT twitter
01:04 PM LeelooMinai: Well, for my defense, this is some teacher at univerrsity or what it is: https://www.youtube.com/watch?v=lzBGZaS1apw&feature=youtu.be&t=68
01:05 PM IchGucksLive: Covfefe might be a RUS code so be aware of steam running cars next
01:05 PM Crom: IchGucksLive: That is very nice!
01:05 PM IchGucksLive: Crom: on what
01:05 PM Crom: the swag for the kids that lantern
01:06 PM LeelooMinai: And I just got my 1920x1080 touch monitor for linuxcnc - wee...
01:06 PM Crom: nice!
01:06 PM IchGucksLive: LeelooMinai: so your are at the front end
01:07 PM IchGucksLive: while i try to build 12 CNC router below 1000USD
01:07 PM IchGucksLive: at 10x10x4
01:07 PM LeelooMinai: IchGucksLive: Well, I did not just buy it normally - I got it from ebay sale from some company for sub $80...
01:07 PM Crom: 10meter 10cm 10feet 10yards?
01:07 PM LeelooMinai: New ones are rather expensive.
01:08 PM nos: IchGucksLive: That's not gonna prevent me from learning from you. :p
01:08 PM nos: Now I know how to set tool radius!
01:08 PM IchGucksLive: Crom: inches
01:08 PM nos: in LCNC...
01:08 PM IchGucksLive: nos its only virtual
01:08 PM Crom: wooo that will be fun
01:08 PM nos: oh
01:09 PM LeelooMinai: nos: For most things you will probably use CAM output anyways:)
01:09 PM IchGucksLive: nos its not effecting tool table at all
01:09 PM nos: I see...
01:10 PM nos: We haven't started learning CAM yet. I think I'm pretty good at G-code by now, and can even program macros.
01:10 PM IchGucksLive: thats the way to do it first
01:10 PM IchGucksLive: then you can read the g-code and find the mistakes
01:11 PM nos: It's pretty sweet to be able to walk up to a CNC machine's console and just tell the thing what you want. :)
01:11 PM LeelooMinai: Right, if you can read it - it's not exactly human-friendly notation though.
01:11 PM IchGucksLive: i need to leave early DRY outside garden crying for water
01:12 PM nos: Syntax highlighting helps a lot. LCNC has syntax highlighting for Vim, and there is also a plugin for Notepad++ on github.
01:12 PM IchGucksLive: see you tomorrow over and out from a German old man
01:12 PM nos: o/
01:12 PM IchGucksLive: nos also on gedit
01:12 PM nos: nice, I'll find it :)
01:14 PM LeelooMinai: nos: Right, I researched editors a bit, and have chosen Atom on windows for g-code. It has zillion plugins, and if you choose them right, you end up with pretty decent setup. I run it under Windows but edit directly the files on my linuxcnc Debian through network - the editor is pretty cool.
01:15 PM LeelooMinai: If you play with configuration you can achieve some neat results. For example, I get file tabs colored by the machine where the file resides. So I can see if I am editing local file, file on my linuccnc machine, my linux server, etc.
01:15 PM LeelooMinai: And the g-code syntax highlight is pretty decent.
01:17 PM nos: LeelooMinai: I will try it!
01:17 PM JesusAlos: Hi
01:18 PM nos: hello!
01:18 PM TurBoss: hello
01:18 PM nos: Currently the problem I have with Vim is that it seems to be so deeply integrated into Arch Linux that I can't really replace it with a version compiled with more options...
01:18 PM Crom: Morning Jesus
01:19 PM JesusAlos: I try to configure XY machine. Not use Z axis. Does any body know about a config?
01:19 PM LeelooMinai: nos:The syntax higlight package is called language-linuxcnc-gcode - you will need to install it, but they have pretty awsome system for plugins, etc.
01:19 PM JesusAlos: If I configure a machine with limits, the machine never find Z axis, because there no are Z motor
01:21 PM Crom: Jesus in the .ini file in the [TRAJ] section AXES = 3 make it read AXES = 2 and COORDINATES X Y Z to COORDINATES X Y
01:21 PM JesusAlos: Will be enough?
01:22 PM Crom: then below that there is a JOINT 2 section and an AXIS_2 section you can remove those as well
01:22 PM Crom: that should do it
01:24 PM LeelooMinai: JesusAlos: Your nick is evil. Now when I read people addressing you I think they just discovered something terrifying.
01:27 PM Crom: oops [JOINT_2] is in linuxcnc 2.8.x
01:27 PM roycroft: how's the welding going, leeloominai?
01:27 PM Crom: Jesus: so you should just have [AXIS_2] section... though you can just leave that...
01:29 PM LeelooMinai: roycroft: Not yet decided what to do. I think I will watch some more videos, and buy new electrodes and give it a test try to see if I can achieve something without a catastrophe in my basement.
01:29 PM Crom: I worked with a Jesus De Jesus
01:29 PM roycroft: jesus is a very common hispanic name
01:29 PM Crom: what were his parents thinking!
01:30 PM JesusAlos: Yes is a common name
01:30 PM JesusAlos: here, in Spain
01:30 PM LeelooMinai: I could probably use my old table after some reinforcements, but now OCD made an image of a nice welded CNC stand, painted and strong for a small elephant to sit on it, etc.:)
01:30 PM Crom: roycroft: very... I know about 10 Jesus' 30 Jose's
01:31 PM JesusAlos: yes
01:31 PM JesusAlos: also José
01:31 PM LeelooMinai: JesusAlos: lol, it must be weird when a friend calls you across the street "Jesus!!!" and people look around checking if someone is having a heart attack or his arm detached from the body or some other terrible accident happened:p
01:31 PM Crom: My Meternal, Maternal, Grandgrand Mother was Spanich
01:32 PM Crom: My Meternal, Maternal, Grandfather was German they met and married 'in service' in England
01:33 PM Crom: He was a valet and she was an upstairs maid
01:33 PM JesusAlos: Is more common situation when somebody Sneeze
01:34 PM LeelooMinai: I think my 134th grandfather was a Neanderthal, but I am not entire sure:)
01:34 PM LeelooMinai: entirely*
01:34 PM nos: LeelooMinai: This Atom editor has a really nice Vim plugin. :)
01:34 PM LeelooMinai: nos: Don't be crazy:)
01:34 PM Crom: heh.. my maternal paternal; grandparents didn't get married until after they had 7 kids and thier former spouses died..
01:35 PM nos: I can't help it. I learned some Vim commands and they turned me crazy.
01:35 PM Crom: nos I have the same problem... my first real word processor was wordstar
01:36 PM Crom: damn .pg should work!
01:36 PM nos: hehe
01:36 PM LeelooMinai: Well, from what I have seen so far, that Atom editor is pretty customizable - I did some pretty detailed customizations for myself, since I am generaly picky about editors.
01:37 PM JesusAlos: Thank all. I must to go to change some diaper.
01:37 PM Crom: now I mainly use joe on unix's and qedit or ultraedit on wdos/windows machines
01:37 PM JesusAlos: Good night
01:37 PM Crom: JesusAlos: cheers..
01:38 PM LeelooMinai: Hmm, I am not yet at a stage that I would wear dipers because I am too lazy to go to bathroom or too involved in IRC, etc., but I will keep the idea in mind:)
01:39 PM LeelooMinai: But I read about some factory where they made people wear dipers to they do not waste too much time with bathroom breaks.
01:39 PM LeelooMinai: "it was weird"
01:40 PM nos: lol
01:42 PM LeelooMinai: lol: "RED FLAG: Trump Asking World Leaders to Call His Mobile Phone"
02:14 PM LeelooMinai: Hmm...
02:17 PM LeelooMinai: My musings brought me to "but bridges do not seem to be welded - they use a lot of bolts and gussets"
02:18 PM LeelooMinai: So it's my new "idea" for the cnc stand - square steel tubing + gussets, lots of drilling and bolts - probably not very time-effective, but should be ok, no?
02:20 PM LeelooMinai: For bonus OCD points I could even use Fusion 360 to model forces on the stand, do those nice simulations that will color the material according to the stress, etc.
02:21 PM LeelooMinai: Has anyone done of those in Fusion? I know they are there, but did not really do anything with it yet. Can you model bolts for example and bolted joints?
02:33 PM SpeedEvil: bolts are just clamps.
02:34 PM LeelooMinai: I know what they do:p
02:34 PM SpeedEvil: They clamp the surfaces together, and you never, ever want to get to a force on the shear-line where it moves.
02:36 PM LeelooMinai: SpeedEvil: Well, I don't know... I googled gussets and looked at pictures for, you know, bridges, "towers" for high voltage lines, things like that - not 100% sure that the joints were supoosed to withstand forces only in one plane.
02:37 PM LeelooMinai: They use a lot of bolts there in grids though. I mean I am not building a bridge - the CNC is probably 100kg at most.
02:38 PM SpeedEvil: The shaft of a bolt should (usually) carry a purely tensile load. It does not constrain the forces in other directions. If it does, the joint it's clamping is slipping, and will fret with movement back and forth.
02:38 PM LeelooMinai: And by a lot I meant a lot:) https://s-media-cache-ak0.pinimg.com/736x/1b/08/54/1b08546ded718624423c999e5d1d4f70.jpg
02:39 PM LeelooMinai: SpeedEvil: Ok, but to go from rest mode to slip you need some threshold force I assume. If you are not crossing that threashold should there be even any problem?
02:39 PM SpeedEvil: yes.
02:39 PM LeelooMinai: Like what...
02:40 PM SpeedEvil: Coefficient of friction times force on the joint
02:40 PM LeelooMinai: No, I mean what is the problem if you do not exceed that threshold?
02:40 PM SpeedEvil: If you don't, then you can simply analyse it as a clamped joint - the bolt details don't actually matter
02:41 PM LeelooMinai: Right, so I was thinking, if I overkill on bolts a bit, it should be as rigid as welded.
02:42 PM SpeedEvil: Yes.
02:42 PM SpeedEvil: Modulo only having one thickness to work with
02:43 PM LeelooMinai: I will need to do a lot of drilling, well... Unless, as someone mentioned yesterday one can "punch" holes with a press, but not sure if that's possible with 1/8 steel tubes, say.
02:43 PM SpeedEvil: you will tend to crumple them
02:43 PM SpeedEvil: you need a die inside the tube to do that
02:43 PM LeelooMinai: well, I would think insert something into them
02:43 PM SpeedEvil: flow drilling is also a thing.
02:44 PM SpeedEvil: Though may not be appropriate
02:44 PM LeelooMinai: The what?
02:44 PM SpeedEvil: You take a carbide fluted coneish shaped thing, and jam it into the metal at high force and rpm
02:44 PM SpeedEvil: it melts/presses its way through
02:45 PM SpeedEvil: It needs quite high powers.
02:45 PM LeelooMinai: Right, no, I mean low-tech methods without much investment in tools. Since I kind of already decided that I probably want to invest in a metal bandsaw.
02:46 PM LeelooMinai: I think I will just drill. I drilled holes with cobalt drills in 1/4 steel angles in the past.
02:46 PM LeelooMinai: It isn't that bad really if one has good drill press.
02:47 PM LeelooMinai: Just wonder if punching holes in steel that is not just thin "sheet" is "a thing".
02:48 PM phipli: blacksmiths do such things with hot metal
02:49 PM LeelooMinai: Hmm.. "3/4" hole in 1/4" plate: 14.7tons"
02:49 PM LeelooMinai: That's not too bad - 20 ton press is not really exotic it seems.
02:49 PM LeelooMinai: But I cannot buy both the bandaw and the press:)
02:49 PM phipli: also, that is how they put holes in oil pipelines isn't it?
02:50 PM nubcake_ is now known as nubcake
02:50 PM phipli: punch a hole... with explosives
02:50 PM LeelooMinai: lol, explosives...
02:50 PM phipli: the sledgehammer of the chemical world
02:50 PM phipli: a tool for every occasion
02:51 PM LeelooMinai: phipli: You may as well take an anti-tank gun and have fun shooting at the pipe:)
02:51 PM phipli: I can haz?
02:51 PM LeelooMinai: Well, same idea, no? :p
02:51 PM phipli: :)
02:52 PM phipli: I keep meaning to make my boss an "In Case of IT Emergency, Break Glass" box
02:52 PM phipli: with a lump hammer in it
02:52 PM LeelooMinai: Probably "autism" talking, but when I imagine making a hole in steel with a press, it's kind of cool - you can do it slowly in controlled fassion.
02:53 PM LeelooMinai: And you just do it mechanically with no noise, electricity, etc.
02:53 PM LeelooMinai: I must try it one day.
02:54 PM LeelooMinai: Probably it's not as cool as I think, and you get some deformations, etc.
02:54 PM phipli: appropriate tooling
02:55 PM archivist: hot metal and speed
02:55 PM phipli: https://www.youtube.com/watch?v=3ET949Pmu6w
02:56 PM archivist: and large flywheels to store the energy for the punch operation
02:57 PM LeelooMinai: archivist: That's "retarded" to me:) Hydraulic press seems better.
02:57 PM gregcnc: holes are punched in structural steel beams all the time
02:57 PM LeelooMinai: I mean that press with wheel where they guy seems doing a lot of work.
02:57 PM phipli: fly press
02:58 PM archivist: they have hydraulic accumulators on really big presses
02:58 PM phipli: although I'm used to seeing them with two large weights
02:58 PM phipli: actually quite dangerous machines - people get a bump on the head and it flattens them
02:58 PM archivist: I gained a fly press about a year ago
02:58 PM phipli: forever
02:59 PM archivist: missing weights error though
02:59 PM phipli: :(
02:59 PM LeelooMinai: Little bump on the head here or there - it just makes you look more seasoned:)
03:00 PM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=fly+press+denbigh
03:00 PM Crom: I'd love to get a metal worker
03:00 PM phipli: k.v = 1/2.m.v^2
03:00 PM phipli: bit m = not health
03:00 PM phipli: *big
03:00 PM LeelooMinai: archivist: Wonderful - with you it always ends with some machines that look like going directly to a museum:)
03:00 PM phipli: and also k.v = k.e.
03:01 PM archivist: possibly older one http://www.collection.archivist.info/searchv13.php?searchstr=fly+press+waterlow
03:01 PM phipli: Hum
03:02 PM phipli: has anyone ever CNC'd a metal scraper?
03:02 PM LeelooMinai: Er, CNCed scraper? Llike machine the scraping tool/blade from a blank?
03:02 PM archivist: dont think that is entirely sensible
03:03 PM phipli: :'(
03:03 PM LeelooMinai: I think it's supposed to be pretty hard:)
03:03 PM phipli: have I got the right word - the thing that is like a mill... but older
03:03 PM phipli: big leaver
03:03 PM LeelooMinai: I have 3 tiny ones now, and seems like they were, grinded maybe?
03:03 PM phipli: and you pull a blade over the work
03:03 PM gregcnc: shaper
03:03 PM phipli: yes
03:04 PM phipli: just got there
03:04 PM phipli: while looking into the middle distance
03:04 PM phipli: :)
03:04 PM phipli: a CNC shaper is what I meant :)
03:05 PM archivist: not much to cnc on a scraper http://www.ebay.co.uk/itm/2-MOORE-WRIGHT-ENGINEERS-SCRAPERS-STRAIGHT-CURVED-APPROX-10-VERY-GOOD-/112425911512
03:05 PM gregcnc: I think I saw mention of it once, but hardly anyone uses a shaper for anything at all
03:05 PM LeelooMinai: It rings a bell probably - but not in my head:)
03:05 PM archivist: shapers do keyway slots
03:05 PM LeelooMinai: Right, it's pretty much a chiesel but with different shape.
03:06 PM archivist: but a broach is faster
03:06 PM phipli: https://www.youtube.com/watch?v=Omsyy-RiaqU
03:06 PM gregcnc: shapers did keywas slots 100 years ago
03:06 PM phipli: that is...
03:06 PM phipli: hypnotic
03:07 PM phipli: almost as bad as watching industrial forging videos
03:07 PM LeelooMinai: However, having said that, after watching that video where they had scraping class, their scrapers were nothing like that - they were huge and some even had big "mushrooms" on the end so you could use the body to lean on them. And of course they also had electric scraper tool.
03:07 PM archivist: go to a forge and see it live
03:08 PM phipli: The train factory here had a huge building that has described to me as just like a cliche of hell
03:08 PM phipli: but they shut it in the late 80s / early 90s (the forge)
03:08 PM phipli: it is now the cad / design office...
03:10 PM archivist: I was there on the day this pic was taken http://www.geograph.org.uk/photo/1689068
03:11 PM archivist: 3 or 4 of us managed to visit
03:11 PM gregcnc: another shaper https://www.instagram.com/p/BSS1CRfgANJ/
03:11 PM LeelooMinai: archivist: How old ar you? 120? :p
03:11 PM archivist: they were making rings from solid and punching out a hole
03:12 PM archivist: that image is only 7 years ago
03:13 PM phipli: :)
03:13 PM LeelooMinai: gregcnc: That looks like metal version of, damn, forgot the name of that woodworking tool, I have one even...
03:13 PM LeelooMinai: plane!
03:13 PM phipli: heh
03:13 PM phipli: it is
03:14 PM phipli: sort of a linear lathe as well...
03:15 PM LeelooMinai: Potato/carrot peeler, only bigger.
03:15 PM _methods: isn't that a planer?
03:16 PM archivist: http://www.geograph.org.uk/photo/1668885 I was here too 8000 tons
03:16 PM gregcnc: shaper tool moves, planer table moves
03:16 PM phipli: hand planer
03:16 PM archivist: down from its original 12000 tons
03:16 PM phipli: I think is meant
03:16 PM LeelooMinai: archivist: Seems that would punch through 1/4 steel:p
03:16 PM phipli: tricky to move the table with a hand planer
03:16 PM _methods: pretty sure that table is doing the moving but hard to tell from that video
03:17 PM archivist: it was bending 6" plate
03:17 PM LeelooMinai: For what? Battleships? :)
03:17 PM archivist: yes
03:18 PM LeelooMinai: :/
03:18 PM phipli: :)
03:18 PM phipli: that in the UK then?
03:19 PM phipli: Ah. Sheffield
03:19 PM phipli: Steel land
03:19 PM phipli: DAYTRIP!
03:19 PM LeelooMinai: Land of fresh air and evergreen forests.
03:20 PM archivist: phipli, we had a wonderful day :)
03:20 PM archivist: alas that last press is no more
03:20 PM phipli: sigh
03:21 PM phipli: next door are fighting
03:21 PM LeelooMinai: "someone stole it"
03:21 PM archivist: probably shops on that site now
03:22 PM phipli: went to one of the old GEC factories in Rugby a few years back
03:22 PM phipli: they made those motor pods that go under warships
03:22 PM phipli: for 360 degree thrust
03:22 PM archivist: they had an old electric Royce crane which we were allowed to see (1919 iirc)
03:23 PM phipli: bolted the motor coils together
03:23 PM LeelooMinai: BTW, as to the biggest things, yesterday I saw that: http://www.cnn.com/2017/05/31/us/worlds-largest-airplane-rolled-out-paul-allen/
03:23 PM phipli: and had a vacuum chamber about twice the height of my house to get the air out of the insulation or something like that
03:23 PM archivist: phipli, I am not far form Rugby
03:23 PM LeelooMinai: An airplaine for transporting rockets...
03:24 PM Crom: guppy?
03:24 PM phipli: LeelooMinai: I saw that in the news. Awesomes
03:24 PM LeelooMinai: Or rather flying them up to start.
03:24 PM Crom: oh the allen plane
03:24 PM LeelooMinai: lol @ 28 wheels
03:24 PM phipli: archivist: I used to live in Cov
03:25 PM archivist: been near Burton upon Trent since 1966/7
03:25 PM phipli: heh
03:25 PM phipli: local
03:25 PM phipli: I'm in Derby now
03:25 PM archivist: beer town
03:25 PM phipli: just a trip down the A38
03:26 PM phipli: both of us
03:26 PM phipli: you have the factories
03:26 PM archivist: we were steaming Leawood yesterday for the beed
03:26 PM phipli: and smaller breweries - we have the pubs and tiny breweries
03:26 PM archivist: steaming sat sunday to
03:26 PM phipli: Have you been to the tower brewery in Burton?
03:27 PM archivist: many years ago
03:27 PM phipli: I've not been to Leawood
03:27 PM phipli: been to Papplewick
03:27 PM archivist: this weekend then!
03:28 PM phipli: up Nottingham way
03:28 PM phipli: you volunteer there?
03:28 PM archivist: one of the engine drivers, so yes
03:29 PM phipli: :)
03:30 PM archivist: as we were running yesterday by sunday will have very sooty tubes, dunno how well it will be running
03:31 PM phipli: Is it possible to walk from Whatstandwell?
03:32 PM phipli: (don't have a car on the road atm)
03:32 PM archivist: http://www.middleton-leawood.org.uk/
03:32 PM phipli: or Cromford
03:32 PM archivist: not that far from Whatstandwell at all
03:33 PM archivist: there is a boat trip from Cromford down
03:33 PM archivist: http://www.middleton-leawood.org.uk/
03:45 PM phipli: Saturday would probably be better for us
03:46 PM archivist: we are supposed to start the engine midday, timings depend on warming through
03:46 PM phipli: oooh
03:46 PM phipli: weather looks good
03:46 PM phipli: heh. Sunday is rain.
03:47 PM archivist: yesterday, no advertising, we had around 200 visitors
03:47 PM archivist: really odd day
03:51 PM phipli: heh
04:13 PM Tom_L: JT-Mobile what's up?
04:14 PM XXCoder: yay. I can't wait for brown air to come back. he just withdrew from paris agreement
04:18 PM LeelooMinai: It's decided already?
04:19 PM XXCoder: apparently
04:19 PM LeelooMinai: Great. So, I guess China is new World Leader now.
04:20 PM gregcnc: yeah, I'm already in the process of replacing all my cars with 1940's models
04:20 PM phipli: Have you considered using coal fired cars?
04:21 PM gregcnc: natural gas furnace going to coal
04:21 PM LeelooMinai: Damn, indeed - CNN has it too. Musk rage-quit, as he promised.
04:21 PM XXCoder: musk actually does what he promises
04:21 PM XXCoder: unlike certain ceos I remember reading about
04:22 PM XXCoder: couple said they would move out of usa if obama was voted
04:22 PM XXCoder: still living in usa
04:22 PM JT-Mobile: hey Tom_L we are in Galveston, starting home tomorrow
04:22 PM phipli: brb
04:22 PM Tom_L: you missed my note
04:23 PM Tom_L: JT-Mobile, did you come in on 45?
04:23 PM JT-Mobile: yea it disconnects afer a while
04:23 PM JT-Mobile: yea
04:23 PM Tom_L: on your way out if you take 610 it's alot quicker than going thru on 45
04:23 PM LeelooMinai: I thknk Trump quit becaue he was still remembereing French leader trolling him mercillessly. He is so stupid, that this probably affected him a lot./
04:23 PM Tom_L: it reconnects on the far side
04:25 PM JT-Mobile: I wonder which roads are full of morning commuter traffic
04:25 PM Tom_L: 45
04:25 PM JT-Mobile: from the north?
04:25 PM Tom_L: it's a mess any way you look at it
04:25 PM Tom_L: heading out from galveston we take 45 to 610 and around
04:25 PM JT-Mobile: oh yea I bet from the south too with all the nice holmes out there
04:26 PM Tom_L: and reconnect with 45 on the north side
04:26 PM Tom_L: yeah it's busy both ways
04:26 PM JT-Mobile: connect to 69
04:26 PM Tom_L: if you wanna go that way yeah
04:26 PM JT-Mobile: ain't going north on 45
04:26 PM Tom_L: we catch 45 on the north end
04:26 PM JT-Mobile: yea I usually take 69/59 out
04:27 PM Tom_L: 610 will save you half an hour probably
04:27 PM JT-Mobile: ok
04:27 PM Tom_L: maybe more
04:28 PM LeelooMinai: Hmm, found a metal cutting bandsaw for, more or less $220 USD - I wonder if such a cheap one can be useful for occasional use, or waste of money.
04:29 PM XXCoder: lee I saw project online to turn one of those into pivot cutting station
04:29 PM LeelooMinai: https://www.princessauto.com/en/detail/4-1-2-in-metal-cutting-band-saw/A-p8699159e
04:29 PM XXCoder: you know, press button and it slowly cuts down metal bar
04:29 PM XXCoder: ah thats entire kit as is. interesting
04:30 PM Tom_L: JT-Mobile, so you avoid dallas?
04:30 PM Tom_L: i guess that would be out of the way for you
04:30 PM LeelooMinai: I mean, I know it's not great, and the stand probaly is wobbly, etc. but, maybe it can cut something when put on good stable bench... I don't know.
04:31 PM XXCoder: LeelooMinai: if its far enough below average maybe you can upgrade it and stuff
04:31 PM roycroft: that saw will work fine
04:31 PM XXCoder: make it into better kit
04:31 PM roycroft: i had a 4x6 like that for years
04:31 PM roycroft: you can build a better stand for it out of wood
04:31 PM LeelooMinai: roycroft: You think worth the money?
04:31 PM roycroft: but if you don't move it around it will be fine on that stgand
04:31 PM roycroft: i sold mine, which was a jet, and about 25 years old, for US$125
04:32 PM roycroft: and mine was pretty beaten up
04:32 PM JT-Mobile: Tom_L, yes avoid dallas like the plague
04:32 PM roycroft: so that's probably fine, especially since it's CDN$, not US$
04:32 PM XXCoder: JT-Mobile: whats wrong with dallas
04:32 PM roycroft: you might also look at getting a porta-band
04:32 PM roycroft: i.e a portable band saw
04:32 PM roycroft: lots of folks have made stands for them
04:32 PM roycroft: it would be more compact
04:32 PM roycroft: but probably not much less expensive
04:33 PM XXCoder: roy depends on usercase I guess
04:33 PM Tom_L: hard to avoid for me since it's straight south
04:33 PM Tom_L: it's not quite as bad as Houston
04:34 PM JT-Mobile: traffic and out of the way 100 miles
04:34 PM roycroft: xxcoder: which is why i present options, and don't try to make decisions for others (most of the time)
04:35 PM JT-Mobile: yea it's 100 miles out of my way, I head north north east from houston
04:35 PM JT-Mobile: I've done the 59 road a bunch of times from houston to the house
04:35 PM XXCoder: off I go to work. laters
04:36 PM JT-Mobile: later
04:36 PM roycroft: so this is what i like about mcmaster-carr
04:36 PM Tom_L: yeah it doesn't look so bad
04:36 PM roycroft: i placed an order with them
04:36 PM roycroft: it never showed up
04:36 PM roycroft: ups "misplaced" it
04:36 PM roycroft: so i rang up mcmaster
04:37 PM roycroft: they asked if i still wanted the stuff
04:37 PM roycroft: and i said "i had to do something else, so i'd prefer not to get it"
04:37 PM roycroft: and they refunded my cc immediately
04:37 PM roycroft: and said they'd deal with ups
04:37 PM roycroft: and apologized
04:37 PM JT-Mobile: if you need to send something back to mcmaster you just send it back and get a credit no problem
04:38 PM roycroft: yes, but they don't refund shipping normally
04:38 PM Tom_L: JT-Mobile, you could take the outer loop but it's a toll road
04:38 PM roycroft: on this they just refunded everything
04:38 PM roycroft: no questions
04:38 PM JT-Mobile: no, unless it is their fault
04:38 PM roycroft: this was ups' fault
04:38 PM roycroft: but they're willing to eat it
04:40 PM gregcnc: UPS will cut them a check, they aren't eating anything it's normal procedure
04:48 PM phipli: swear my laptop puts out more heat than my desktop
04:49 PM roycroft: my mbp definitely becomes a birth control device if i'm doing a 3d rendering in solidworks or something like that wioth it
04:49 PM JT-Mobile: 1100 miles down 700 left to go
04:49 PM roycroft: with
04:49 PM JT-Mobile: hey phipli
04:49 PM phipli: evening JT-Mobile
04:49 PM Tom_L: JT-Mobile, night driving?
04:49 PM JT-Mobile: no, two days left
04:50 PM Tom_L: where ya headed next?
04:50 PM Tom_L: any ships at the dock while you were there?
04:50 PM JT-Mobile: going 450 miles tomorrow arkadelphia
04:51 PM JT-Mobile: didn't seen any ships except out at sea
04:51 PM Tom_L: they're usually there on the weekends
04:51 PM Tom_L: did you see any catrina waterlines on the buildings?
04:51 PM JT-Mobile: phipli, been reading the cookbook some
04:52 PM JT-Mobile: Tom_L, no all cleaned up I guess
04:52 PM Tom_L: a couple buildings marked it
04:52 PM JT-Mobile: missed that
04:52 PM Tom_L: probably 18" or so above the doorways
04:52 PM Tom_L: we were there not too long after it hit
04:52 PM Tom_L: alot of the homes were abandon
04:53 PM Tom_L: it was pretty well cleaned up last time we visited
04:54 PM Tom_L: in March? i don't recall now
04:54 PM JT-Mobile: I don't recall either
04:54 PM phipli: JT-Mobile: useful book. Lots of handy snippets to include in your own code
04:55 PM phipli: Brother's put another project on his website
04:55 PM Deejay: gn8
04:55 PM JT-Mobile: which site is that?
04:55 PM phipli: when I make enclosures, they never look as neat as his
04:55 PM phipli: http://www.nervoussquirrel.com/merge_festival_dodgems_2017.html
04:56 PM JT-Mobile: pretty cool
04:56 PM Tom_L: what cookbook?
04:56 PM JT-Mobile: ardweenie cookbook second edition
04:57 PM Tom_L: oh
04:57 PM phipli: "Arduino Cookbook" by O'Reilly
04:57 PM phipli: (publishers)
04:57 PM JT-Mobile: you can find copies on line
04:59 PM phipli: http://it-ebooks.info/
04:59 PM phipli: copy on that website
04:59 PM phipli: along with a million other programming / software books
05:00 PM phipli: ah, they're having problems again
05:00 PM phipli: "downloading temporarily unavailable"
05:01 PM phipli: which is why I downloaded everything I could think of from them :)
05:01 PM LeelooMinai: phipli: Not trying to be an "ass" or anything, but Arduino is not really a great "platform". It can be if limited ambitions, or you don't care about means, but results, but it's a dead end if you want to keep growing in terms of embedded.
05:01 PM JT-Mobile: LeelooMinai, what do you suggest for a chicken door?
05:01 PM phipli: LeelooMinai: I started in pic assembly and worked backwards
05:02 PM phipli: Arduino is /easy/
05:02 PM LeelooMinai: JT-Mobile: lol. I think for a chicken door you can use whatever your heart desires:p
05:02 PM phipli: which is why it is useful
05:02 PM JT-Mobile: exactly
05:03 PM Tom_L: i did pic basic and pic c then switched to avr, avoid arduino like the plague
05:03 PM LeelooMinai: Right, I am talking from a view of more advanced designs, more elegant programming, etc.
05:03 PM Tom_L: some asm on avr
05:03 PM phipli: less point than on pic
05:03 PM JT-Mobile: in the same way I tell customers they don't always need an AB compactlogix plc when a click will do the job for $80
05:03 PM phipli: AVRs are optimised for C
05:04 PM phipli: ARM is the bang for buck these days
05:04 PM phipli: when you can get a ghz processor for £4
05:04 PM phipli: (on a board)
05:04 PM LeelooMinai: ARM was a better choice for a long time time - probably at least half a decade if not more.
05:04 PM Tom_L: alot more register setup though
05:04 PM Tom_L: you can get one for $2 mounted on a breakout board
05:04 PM malcom2073: The new rage is fpga/arm combos now, they're dropping in price fast
05:05 PM phipli: LeelooMinai: I have an Acorn A3010 in the shed from back when the A in ARM stood for Acorn
05:05 PM LeelooMinai: Talking about AVR/PIC etc at this point is pretty much like talking about 286-based PCs:) I mean, ok, if they work for you, fine, but, dead end:)
05:06 PM malcom2073: LeelooMinai: ARM still can't beat the power consumption and cost of one of the little atmegas if you don't need all that power
05:07 PM phipli: and they're nice to work with
05:07 PM phipli: tough
05:07 PM phipli: I've not blown one yet
05:07 PM phipli: and I've accidentally tried quite hard
05:08 PM phipli: and they're easy going about free samples...
05:08 PM LeelooMinai: malcom2073: That's not necessarily true even. If you have an application where you need to do something periodically, then sleep, etc., which is most micro usage cases actually, those ARMs will eat those ancient micros for breakfast.
05:08 PM LeelooMinai: In terms of power consumption I mean.
05:09 PM malcom2073: LeelooMinai: If you need to sleep all the time maybe, but not if you need to be active all the time
05:10 PM LeelooMinai: malcom2073: But you are not going to be active all the time in 99% of cases probably - or at least you don't want to be.
05:10 PM malcom2073: fwiw, the attiny85 uses less current in deep sleep than a cortex m0
05:11 PM LeelooMinai: Yes, but it can sleep then become a snail and sleep again, while ARM will wake up like a daemon from hell, do the processing in 1/100th the time and sleep again:)
05:12 PM LeelooMinai: Also, nowadays you have a big range of low-power ARMs. Read the specs one day and you will see that they have some pretty impressive power-saving options and modes.
05:12 PM malcom2073: Which once again, works if your application allows the chip to sleep
05:13 PM malcom2073: I've found using the smallest lowest power device for each task has served me quite well, no reason to go for the high horsepower beast every time
05:13 PM LeelooMinai: malcom2073: Yes, but give me an example of application that needs to work 100% of the time at full speed - it's not a server...
05:13 PM phipli: audio recording
05:13 PM malcom2073: watchdogs
05:14 PM malcom2073: datalogging
05:14 PM phipli: vibration analysis
05:14 PM LeelooMinai: malcom2073: That's nice, but does not scale - next time you may need some more processing and you will have a problem.
05:14 PM malcom2073: No it doens't scale, but if I needed scale I would've designed for it :-P
05:14 PM phipli: anyhow
05:15 PM phipli: this is a macs vs. Windows argument
05:15 PM malcom2073: True
05:15 PM LeelooMinai: malcom2073: Hrere are hardware watchdogs in micros, as for datalogging - that may still not require the micro to work full-speed and without gaps in between.
05:15 PM LeelooMinai: Well, no, it isn't really, but ok - I mean I would have to spend next half a day detailing everything.
05:16 PM malcom2073: Heh
05:16 PM phipli: I prefer the AVR colour selection
05:16 PM malcom2073: phipli: color
05:16 PM * malcom2073 runs
05:16 PM phipli: *colour
05:16 PM SpeedEvil: ESP32, for example, has two 160MHz or so cores, with one low power '8 bit' core that runs at low speed for doing watchdoggy stuff
05:16 PM SpeedEvil: And reading sensors
05:17 PM nubcake: night everyone :)
05:17 PM malcom2073: I like the dual core stuff, LPC43XX series has that too
05:17 PM phipli: I'm playing at datalogging to the SPI Flash on an esp8266 atm
05:17 PM phipli: 3Meg spare is /loads/ of space for 8 bit values
05:17 PM phipli: I like ESPs
05:17 PM malcom2073: I'm going to pretty soon (hopefully) start getting into the smartfusion stuff
05:17 PM phipli: not done anything with the ESP32s yet - they're sat on the side
05:18 PM phipli: malcom2073: played with a parallax propeller?
05:18 PM malcom2073: phipli: I've not, no
05:18 PM phipli: they're weird but kind of mind stretching to program
05:18 PM phipli: 8 cores
05:18 PM phipli: and most common internal helpers missing
05:19 PM phipli: good to have a go with just to make you think
05:19 PM malcom2073: Yeah, I've not really been able to find anything I wanted to use it for
05:19 PM phipli: If I remember, there aren't any interrupts - you just use a tight loop to watch the input with a core
05:19 PM malcom2073: they're not realtime enough to do things like engine control, and that doesn't really benefit from more than two channels
05:19 PM malcom2073: cores*
05:20 PM phipli: you do homebrew ECUs?
05:20 PM malcom2073: Yeah, I mostly do the software side, but I'm trying to get more into hardware as I learn

05:20 PM phipli: malcom2073: homebrew or work?
05:20 PM malcom2073: phipli: home
05:20 PM phipli: (but awesome none the less)
05:20 PM phipli: *ether way
05:21 PM Tom_itx: http://tinyurl.com/y7nwvf5e
05:21 PM phipli: a few years back I tried to look into it but the internet said "NONE SHALL PASS"
05:21 PM phipli: which made me sad
05:21 PM malcom2073: phipli: You're not looking in the right spot, we've been doing it for 10+ years :-D
05:21 PM malcom2073: nowadays there are even arduino based ecu's that are pretty good
05:21 PM phipli: malcom2073: yeah - I couldn't understand it
05:22 PM Tom_itx: i saw one of ^^ those for about 2 bux recently
05:22 PM phipli: if they could do it in the late 70s early 80s, why not at home now
05:22 PM malcom2073: Exactly, my 80's GM ecu only ran 1mhz
05:22 PM phipli: I presume they had dedicated hardware for some functions
05:22 PM malcom2073: And on like, 32kb of memory?
05:22 PM phipli: (but then so did computers - eg the Amiga)
05:23 PM Tom_itx: http://tinyurl.com/ze4oq23
05:23 PM Tom_itx: STM32
05:23 PM Tom_itx: 1.78
05:24 PM malcom2073: Yeah those dev boards are cheap... you gotta worry though, when the dev board is cheaper than the chip....
05:24 PM malcom2073: Probably a clone chip
05:24 PM Tom_L: you can still develop with it
05:25 PM malcom2073: Yep
05:27 PM LeelooMinai: For hobby projects at this time cost of micro/dev board is negligible - you will spend much more money elsewhere in the process.
05:27 PM LeelooMinai: So, as I always said, go for the platform that will five you best tools, best chance to grow, etc.
05:28 PM LeelooMinai: five=give
05:28 PM dioz: wow does formatting options ever suck on mobile
05:28 PM dioz: or i'm just not used to it.
05:29 PM dioz: it ends up directly huffing the offgas of the welding or cutting process is harmful
05:29 PM dioz: who the fucked have though?
05:29 PM LeelooMinai: dioz: I wonder if anyone knows what you are talking about:p
05:29 PM malcom2073: LeelooMinai: Welding on galvanized steel
05:29 PM dioz: i sucked on the end of the OFC torch for about 15 minutes today
05:29 PM malcom2073: He talks about it a lot
05:29 PM dioz: i totally didn't feel anything
05:30 PM LeelooMinai: Ok, but formatting options, mobile...
05:30 PM dioz: it's a .doc file
05:30 PM dioz: formatting is fucked. i only have mobile. can't figure it out right now
05:30 PM dioz: gonna have to wait till i'm at a computer
05:31 PM dioz: i'm smashing the beer then doing some drafting
05:31 PM dioz: beer and lines i call it
05:32 PM dioz: lota and lots of lines
05:32 PM dioz: they give me one side of a off-set-two-ways rectangular transition
05:32 PM dioz: and i have to figure out what the other sides are
05:33 PM dioz: 3 sides
05:33 PM dioz: involves drawing an isometric of the elevation view to get a plan view
05:34 PM dioz: then creating inside patterns after doing math to calculate slant lines
05:34 PM dioz: some guys hold up their hands
05:34 PM gregcnc: what's the beer to line ratio?
05:34 PM dioz: gregcnc: like 700:1 it feels like
05:34 PM dioz: probably ends up being 700:6 though
05:35 PM dioz: i'll post a pic hold on.
05:36 PM malcom2073: Shouldn't do lines with your beer
05:36 PM malcom2073: you'll get a bloody nose
05:37 PM gregcnc: you might drown
05:38 PM dioz: trans https://imgur.com/gallery/dnhqy
05:38 PM dioz: oh shit that pic turned out messed
05:38 PM dioz: wtf happened to that picture?
05:39 PM LeelooMinai: It is a virus picture - it's now eating right side of my monitor.
05:40 PM gregcnc: too much beer not enough lines
05:42 PM dioz: we usually draw obliques at 45 degrees and isometrics at 30 degrees
06:01 PM LeelooMinai: So, I know that's the "bizzare thought' category, but, any thoughts what would be the end result of building something from ABS or PVC pipes, like a cubic frame and then filling the whole thing with concrete, maybe with a littl rebar inside or not. Does that have any chance of being rigid? :)
06:03 PM LeelooMinai: Right, never mind, of course people asked this already: https://engineering.stackexchange.com/questions/2651/would-a-pe-pipe-filled-with-concrete-make-a-good-pillar
06:04 PM Crom: LeelooMinai: yes.. not rebar, but all thread in tubing. when the concrete is dry (30 days) you tighted the all thread rod to put the concrete under compression
06:05 PM LeelooMinai: Why compress dry concrete though?
06:05 PM LeelooMinai: I thought it's pretty incompressible...
06:06 PM Crom: it's how you make concrete rigid
06:07 PM Crom: concrete is crap at tension
06:11 PM phipli: LeelooMinai: you're pre-loading it
06:11 PM phipli: if concrete fails under 1 tonne of tension, you put one tonne of compression on it
06:12 PM phipli: then you can put a tonne of tension on it without it failing because it takes it back to zero
06:12 PM LeelooMinai: Yes, but how exatly would it look. I mean ok, I know what a threaded rod is, but then what - you need something on the tube ends if you want to compress what's inside the tube.
06:12 PM phipli: unless the friction grips it
06:13 PM Crom: you have a big washer to transfer the compression into the concrete and the nut. you can make a little pocket for the washer and nut
06:13 PM LeelooMinai: Right, so like a piston-washer.
06:36 PM LeelooMinai: Heh, Fusion 360 has bolt connection in simulation constraints - neat.
06:36 PM SpeedEvil: :)
06:37 PM LeelooMinai: I am trying something basic - made a square beam and went into static simulation, to see if I can see how it deflects with different loads, different materials, etc. I know in this case there are web calculators, but, this way I will have basics for doing advanced things later.
06:47 PM LeelooMinai: This is so cool. 5 minuts and: http://i.imgur.com/LGX3KEo.png
06:48 PM LeelooMinai: Can also color by other things, like displacement: http://i.imgur.com/JkjGPCT.png
06:49 PM andypugh: Yeah, i am sure they are secretly evil, but right now you can’t argue with what it lets you do.
06:50 PM LeelooMinai: Made 2.5 inch square steel beam with 1/8 inch walls and 2 feet length and applied 100 newtons, so 10 kg to the end - without reading any tutorial or anything.
06:50 PM LeelooMinai: Which means that the UI is intuitive and works.
06:51 PM andypugh: You will be putting me out of the job I don’t do any more :-)
06:51 PM zeeshan: i could calculate that iun a formula in 1 min
06:51 PM zeeshan: :-)
06:52 PM LeelooMinai: zeeshan: You must be one of those "like a smart people" :p
06:52 PM andypugh: zeeshan: But how long to paint the picture?
06:52 PM zeeshan: picture is painted in the mind
06:52 PM zeeshan: =D
06:52 PM zeeshan: LeelooMinai: glad to see you using a real software
06:52 PM andypugh: zeeshan: I would tend to do both, if it mattered.
06:52 PM zeeshan: like fusion
06:53 PM zeeshan: :d
06:53 PM zeeshan: andypugh: same here
06:53 PM zeeshan: i dont trust simulation
06:53 PM zeeshan: as good as bc
06:53 PM zeeshan: i just do f/a in areas where i know there is normal stres
06:54 PM zeeshan: andypugh: i actually do engineering design at work as part of my role!
06:54 PM zeeshan: REAL design!
06:54 PM andypugh: Simulations give you exact answers, but exactly wrong for bad input data
06:54 PM zeeshan: not just cad copying
06:54 PM zeeshan: doing full out calculations!
06:54 PM andypugh: I used to, I liked it
06:54 PM zeeshan: all my buddies have been telling me that ill never use what i learned in school
06:54 PM zeeshan: but i do!
06:54 PM zeeshan: andypugh: a lot of people dont do stuff like mesh sensitivity
06:55 PM zeeshan: or are thinking singularities are real stress areas
06:55 PM zeeshan: i see it a lot
06:56 PM sync: it really depends on your mesher if it is a common problem or not
06:56 PM andypugh: Classic conversation between my sister (a jeweler) and my niece (a 14 year old). “I will never need to use Pi, it’s just pointless”. “I use it every day to know how much gold to cut to make a ring”
06:56 PM sync: I'm positively suprised by star ccm+
06:56 PM LeelooMinai: Well, ok, but seriously. I watched some documentary about people that had some brain injury or just defect, etc. and got "savant" abilities. Most of them were paying for them of course in many other areas (like low IQ, speach, sight, etc.), but one guy was pretty normal for example, just had autism (lol), but could recite PI to 21 thousands places without mistake. Took him 5 hours to even say it and got tired in the process, but
06:56 PM LeelooMinai: still... scary stuff. Others could do things like fly over a city in a helicopter, then sit and draw the 3D picture of it on a wall with tiny details, etc.
06:57 PM zeeshan:
06:57 PM zeeshan: why do i keep getting weird symbols from you mr andy
06:57 PM LeelooMinai: So, maybe zeeshant is one of those people and can draw it in head - who knows:p
06:57 PM zeeshan: LeelooMinai: you are mean
06:57 PM zeeshan: =[
06:57 PM LeelooMinai: Just responding to your meanness:) You don't really want to play "kick me" game with a horse, I am saying
06:58 PM LeelooMinai: :)
06:58 PM zeeshan: i am being mean
06:58 PM zeeshan: but honestly the problem you showed
06:58 PM zeeshan: is a basic problem that is taught in engineering school
06:58 PM zeeshan: its like a small formula
06:58 PM andypugh: zeeshan: I lost my faith in computers meshing with Hyperworks ( a long time ago). Press the “automesh” button. Wait 30 minutes. “meshing failed”. Change nothing. Press the button. “Meshing completed”.
06:59 PM zeeshan: https://cdn.slidesharecdn.com/ss_thumbnails/sbeamdeflectionformulae-121013020925-phpapp02-thumbnail-4.jpg?cb=1350094201
06:59 PM zeeshan: see LeelooMinai
06:59 PM zeeshan: its case one
06:59 PM zeeshan: maximum deflection column..
06:59 PM LeelooMinai: zeeshan: If you read what I wrote, you would see me opening with a statement that I know there are calculators for simple cases like this, beams, moment of intertia idea/formulas, etc., but what's your point:)
06:59 PM zeeshan: P is your force, l is your length of beam, E is 200GPa for steel
07:00 PM zeeshan: I is = 1/12 bh^3(outer square) - 1/2 bh^3(inner square)
07:00 PM LeelooMinai: Yes, and now do that for some construction with 100 bolts and beams all over the place, etc. See you:p
07:00 PM andypugh: The equation is worth knowing, It has a 4th power in it. It is _extraordinary_ how fast things get stiffer with width.
07:00 PM zeeshan: you should at least post pictures of something more complicated then
07:00 PM zeeshan: :(
07:01 PM LeelooMinai: zeeshan: The point was that I just went to the simulation "mode" and did that in 5 minutes without any tutorial, etc. and I get results and now can expand on it (use aluminum, change dimensions, etc.)
07:01 PM zeeshan: LeelooMinai: and you really think you're getting a good result? :)
07:01 PM LeelooMinai: I think that's awsome, but, whatever:p
07:01 PM zeeshan: and you really think all the schooling and math to understand fea
07:01 PM zeeshan: is not needed? :)
07:01 PM zeeshan: its just as simple as constraining, and go!
07:02 PM LeelooMinai: ...
07:02 PM zeeshan: you'll quickly realize in more complicated problems, your answer is likely wrong
07:02 PM LeelooMinai: zeeshan: Are you trying to cast some spell on me or hypnotize me? :)
07:02 PM zeeshan: i'm just telling you that it may take 5 minutes to setup that simple problem
07:03 PM zeeshan: but intrepreting the results takes a lot of experience and knowledge
07:03 PM zeeshan: be ware!
07:04 PM LeelooMinai: zeeshan: You realize that I am not 5 yo? :p
07:05 PM andypugh: You are both right.
07:05 PM Crom: LeelooMinai: you're 4?
07:05 PM LeelooMinai: I am just saying that Fusin360 is neat - don't get to overworked on it:)
07:05 PM andypugh: It’s _brilliant_ that for free you can do that analysis.
07:05 PM andypugh: But, at the same time, how do you know it is true?
07:05 PM LeelooMinai: Well, and the design part of it sketching, 3D, etc. it's all great.
07:06 PM zeeshan: fusion is great for the $
07:06 PM zeeshan: or for being free
07:06 PM LeelooMinai: andypugh: If I want to know if the result is off by 0.1%, I can do reasearch, compare with formula results, etc.
07:06 PM LeelooMinai: But, do I care now about it? Hell no:)
07:06 PM zeeshan: LeelooMinai: you arent getting it
07:07 PM zeeshan: the result can be off by 90231831280921309832108938%
07:07 PM zeeshan: because of incorrect boundary conditions
07:07 PM LeelooMinai: I want to check some differences with different beam cross-sections right now. They can be off by 10% and I would still use it.
07:08 PM LeelooMinai: zeeshan: And you think one will not notice that?
07:08 PM andypugh: A very real example cost me £20. I was building a magneto charger last week. Missed a 0 from an Excel equation, realised after I had bought a 1kg reel of the wrong wire that the computer had given the wrong answer, because I gave it the wrong number.
07:08 PM zeeshan: LeelooMinai: i see people not noticing it all the time!
07:08 PM zeeshan: lol andypugh
07:08 PM zeeshan: i was making an elemental mistake when i was plotting factor of safety
07:08 PM zeeshan: incorrect material set
07:08 PM zeeshan: :-)
07:09 PM LeelooMinai: E, I don't care. I am just glad I have CAD+CAM+simulation+drafting+mesh modeling, and things I don't even know about yet for free for my hobby:/
07:09 PM LeelooMinai: Seems they also have sheet mode in beta now, so probably will release it soon.
07:10 PM LeelooMinai: Forgot about montion study - I already used that when designing the hood for my CNC.
07:12 PM andypugh: We don’t disagree that this is great. But if time or money are involved, then do a simplified hand-calcuation to, and then do a “feel” thing. What size does everyone else use for that job? Does it “look” right. I often set my calipers to what the computer says and thing “does that seem big enough”. Use the computer results, but trust your intuition to spot that you messed up the inputs :-)
07:12 PM LeelooMinai: zeeshan: Also, don't be so sure being qualified for work will be important in the future:) If things go as they go now, future "scientist" may be pretty retarded:)
07:13 PM zeeshan: LeelooMinai: i'm not worried
07:13 PM zeeshan: at all
07:13 PM zeeshan: i deal with enough "qualified retards"
07:13 PM zeeshan: to know even with training, people are clueless
07:13 PM zeeshan: and cant do simple jobs
07:13 PM zeeshan: so the guys without training are likely a far cry away :)
07:14 PM zeeshan: im bitter today cause i had to repeat myself 4 times at work about the same issue
07:14 PM zeeshan: :[
07:14 PM LeelooMinai: andypugh: Come on... I am not naive - I am on IRC for decades:) When I was showing that pic I knew that someone will pop up with "you can do it by hand" story - just was not sure who it will be this time.
07:14 PM zeeshan: LeelooMinai: you set yourself up with it
07:14 PM zeeshan: with a noob SS
07:15 PM LeelooMinai: Yes, because I have good heart:p I knew that, but thought that someone that is doing this in a masochist way and is new, maybe will check the software out.
07:16 PM zeeshan: blind leading the blind
07:16 PM zeeshan: 2017 kickstarter project
07:16 PM zeeshan: :-)
07:17 PM andypugh: OK, here is where some training would help. Did you see where it says “Von Mises” and understand where and why you might choose a different option?
07:17 PM zeeshan: HEHE
07:17 PM zeeshan: what is this convergence thing!
07:18 PM zeeshan: andypugh: i used to think im a pro machinist @ home
07:18 PM zeeshan: i've been helping bring in cam to the shop
07:18 PM LeelooMinai: zeeshan: You know, when I was small I liked to play chess. If I saw someone underestimating me before the game, I was very happy. Often the game went with me being on defense for a long time, and passive, but the end was so satisfying - sudden turn of events and a deadly strike - have it ever happened to you in life? :)
07:18 PM zeeshan: and starting to see how real pros do their work
07:18 PM zeeshan: i got a lot to learn :0)
07:19 PM zeeshan: LeelooMinai: rather than going off topic
07:19 PM zeeshan: you should focus on answering andy's simple question
07:19 PM LeelooMinai: That was very on topic, you just need to apply it to the conversation:)
07:19 PM zeeshan: shrug, seems off topic to me, does not trigger a response out of me
07:20 PM LeelooMinai: Do I have to explain that too:/
07:21 PM andypugh: I think this has become inappropriately confrontational.
07:21 PM zeeshan: :)
07:21 PM LeelooMinai: zeeshan likes to confront me - has happened in the past few times:/
07:22 PM zeeshan: LeelooMinai: i was just stating facts!
07:22 PM LeelooMinai: No, you were assuming things about someone you don't know.
07:22 PM zeeshan: LeelooMinai: you are very emo today
07:22 PM zeeshan: what is up
07:23 PM LeelooMinai: Well, somehow I was not "emo" for long time here and today you appeared - I wonder if that has something to do with that.
07:23 PM zeeshan: hey man i come here sometimes :)
07:23 PM andypugh: it’s just that if you have done the underlying maths in FEA you realise that it’s very sensitive to the input data and boundary conditions, and the fact that it is now so _very_ easy to set up an analysis does not mean that it is any easier to know if that analysis is valid.
07:24 PM andypugh: It’s _great_ that it is so easy (and so cheap)
07:24 PM LeelooMinai: Right, typical
07:24 PM zeeshan: LeelooMinai: i came into the channel and saw these two lines: ] <LeelooMinai> This is so cool. 5 minuts and: http://i.imgur.com/LGX3KEo.png ; <LeelooMinai> Can also color by other things, like displacement: http://i.imgur.com/JkjGPCT.png
07:24 PM zeeshan: the reality is i found that very offensive and belittling to people who actually do that stuff for a living
07:24 PM zeeshan: so i decided to give a smart ass answer
07:24 PM Tom_L: ass
07:24 PM Tom_L: :)
07:24 PM zeeshan: exactly!
07:25 PM LeelooMinai: zeeshan: Sorry, but that's stupid:)
07:25 PM zeeshan: may be to you
07:25 PM Tom_L: ignorance is bliss
07:25 PM zeeshan: LeelooMinai: to be honest im a little suprised that you're talking like that anyway
07:26 PM zeeshan: you're the person who researches the hell out of something
07:26 PM andypugh: I am not offended on any level (I made the rubber models in Radioss, FWIW) and I think that it looks like your result is probably about right.
07:26 PM LeelooMinai: I guess we live in different worlds and there's too big a gap to communicate properly here.
07:26 PM zeeshan: youre like an hour away
07:26 PM zeeshan: :-)
07:26 PM zeeshan: andypugh: Radioss?
07:27 PM zeeshan: RADIOSS is a leading structural analysis solver for highly non-linear problems under dynamic loading
07:27 PM zeeshan: you know something i find very confusion
07:28 PM zeeshan: why do people use certain fea software for certain problems
07:28 PM zeeshan: ive heard of altair being used for crash simulation
07:28 PM zeeshan: then abaqus is dominated by the education industryu
07:28 PM zeeshan: then some people solely use comsol
07:28 PM Tom_L: because someone like you recomended it to them and they bought it
07:28 PM zeeshan: haha
07:29 PM zeeshan: but dude they spend a lot of money on this stuff
07:29 PM zeeshan: theres gotta be some benefit
07:29 PM Tom_L: they don't care
07:29 PM Tom_L: they'll end up selling a bazillion of x product
07:29 PM LeelooMinai: They don't cere and wear red #RADIOSS caps:)
07:29 PM zeeshan: like a lot of software can handle non-linear problems these days
07:30 PM LeelooMinai: "Speaking of solver, Fusion 360 uses Nastran as a solver to run its calculations. Nastran is trusted among the engineering community and was originally developed for NASA to be their robust FEA tool."
07:30 PM sync: everything and their dog has a nastran solver
07:31 PM sync: for legacy reasons
07:31 PM zeeshan: i think even ansys does
07:31 PM zeeshan: lol
07:31 PM sync: but running a card reader every time is not very speedy
07:32 PM LeelooMinai: Just quoted what they use.
07:32 PM sync: (yes, a nastran solver will punch cards and feed them into a card reader)
07:32 PM LeelooMinai: You can use their cloud computing resources or do it locally. But the cloud part has some queue with slots to use, etc.
07:35 PM zeeshan: thats pretty cool
07:35 PM zeeshan: massive super computer
07:35 PM zeeshan: :D
07:36 PM Tom_L: zeeshan, just a cluster of arduinos
07:36 PM zeeshan: haha
07:38 PM LeelooMinai: Hmm...
07:38 PM LeelooMinai: Anyone seen how people appear here sometimes ask questions about basic g-code, free 2D cads, etc.?
07:39 PM LeelooMinai: I have seen few.
07:39 PM LeelooMinai: zeeshan: That pic of mine was for them, not you, in case you are still confused:)
07:40 PM zeeshan: i only see one noob here, u
07:40 PM zeeshan: :-)
07:40 PM Tom_L: just an inquisitive one
07:40 PM LeelooMinai: Yes, that's your problem probably:)
07:40 PM Tom_L: that and carries a chip
07:40 PM zeeshan: lol
07:41 PM zeeshan: leeloo you've gotten a lot cockier after build your wood router
07:41 PM Tom_L: what's a good brand of digital calipers to get nowdays?
07:41 PM zeeshan: =D
07:41 PM Tom_L: mine has a dead spot
07:41 PM zeeshan: honestly dude i have a mitutoyo but i never use it
07:41 PM Tom_L: was looking local today and most are no name
07:41 PM zeeshan: i use china one
07:41 PM LeelooMinai: zeeshan: Well, you seem to be cocky too on IRC, even though your grammar is not so good:)
07:41 PM Tom_L: i can probably get one for $15 or so
07:42 PM zeeshan: http://www.canadiantire.ca/en/pdp/mastercraft-digital-caliper-0586800p.html
07:42 PM Tom_L: i can also get a starrett for 160
07:42 PM Tom_L: or so
07:42 PM zeeshan: it goes on sale for like $19 cad
07:42 PM zeeshan: i think starrett is made in china
07:42 PM zeeshan: its hard spending that kind of $ on something made in china
07:42 PM Tom_L: they both looked about the same to me
07:42 PM Tom_L: i'll probably go cheap since i don't use it as often now
07:43 PM Tom_L: what about the cheap ones at HF?
07:43 PM zeeshan: if you can find the style i posted
07:43 PM zeeshan: i know hf sells one
07:43 PM andypugh: zeeshan: Radioss is an “explicit” FEA code.
07:43 PM Tom_L: +- .1 accuracy :)
07:43 PM zeeshan: but they all sell some sketchy ones
07:43 PM zeeshan: andypugh: so you write subroutines?
07:44 PM zeeshan: internet says you solve for x"
07:44 PM zeeshan: not x
07:44 PM zeeshan: hm
07:45 PM zeeshan: ive never done much non-linear analysis
07:45 PM andypugh: Which means that is considers time / strain rate which makes is suitable for crash simulation with materials where viscosity matters (and if handles inertial loads too). Most solvers assume equlibrium elastic condition.
07:45 PM zeeshan: does it have built in plastic models?
07:46 PM LeelooMinai: andypugh: This is what Fusion has in terms of types of analysis it seems: http://i.imgur.com/lteYmYS.png
07:46 PM LeelooMinai: Shape optimization is pretty cool one.
07:47 PM LeelooMinai: If one 3D prints things I guess or can use molds, etc.
07:48 PM LeelooMinai: The nonlinear static stress one has "Determine the static stresses and deformation throughout the model caused by structural loads and boundary conditions while considering nonlinear material properties and large deformations." in the description/
07:49 PM andypugh: zeeshan: Yes, lots of them. I mainly worked on Mooney-Rivlin parameters for the materials specified for standard crash-test dummies
07:50 PM zeeshan: andypugh: very cool
07:50 PM zeeshan: i pretty much have use multilinear isotropic hardening
07:50 PM zeeshan: thats it
07:50 PM zeeshan: lol
07:50 PM zeeshan: so opened up the good ol atlas of stress-strain curves, put it in
07:50 PM zeeshan: and ran simulation with it
07:50 PM zeeshan: it gives pretty decent results when you get into the plastic range
07:51 PM zeeshan: Tom_L: https://www.youtube.com/watch?v=HpGUOTVBZ3c
07:52 PM andypugh: Going back to LeelooMinai’s beam problem, it’s the difference between “what happens if I hang a 10kg weight on the end” and “how does the stress evolve over the first 100mS if I drop a 10kg weight on the end at 30kph"
07:53 PM LeelooMinai: andypugh: There are other analysis there - I just posted a pic.
07:53 PM zeeshan: LeelooMinai: dont you have to be drilling a hole in steel
07:54 PM zeeshan: :-)
07:54 PM LeelooMinai: andypugh: Like event simulation: "Determine how your design responds to motion (including initial velocities), impacts, and time-dependent loads and constraints. The results include displacements, stresses, strains, and other measurements throughout a specified time period."
07:55 PM LeelooMinai: + nonlinear static stress: my example was just the simples simulation I could think of.
07:55 PM andypugh: That’s the area I was in back in the 1990s. Not any more.
07:56 PM Tom_L: zeeshan, i can close my mics and get them to read anything i need :)
07:56 PM LeelooMinai: Well, in any case, I don't know what zeeshan is about. It's a great tool for many people (Fusion 360), and playing "an expert" that is above all of this is dumb.
07:57 PM andypugh: I would be curious to see if you can set up the event simulation to accurately anayse the impact of a crash-test dummy buttock, which is a mosy peculiar open-cell, viscose material with buckling.
07:57 PM zeeshan: LeelooMinai: you should continue to do some expert beam analysis
07:57 PM zeeshan: :]
07:58 PM LeelooMinai: andypugh: If I needed it for something, the answer is yes - given some time.
07:58 PM zeeshan: andypugh: i suspect not :-)
07:59 PM andypugh: In either case you would still need to correlate to an actual crash test to see if you were close.
07:59 PM Tom_L: zeeshan, seems they all have pretty much the same features anymore
08:00 PM andypugh: LeelooMinai: We are not playing “expert above all this” just trying to say that any simulation needs a reality-check.
08:01 PM LeelooMinai: zeeshan: Imo you should move to US - you would fit there better:)
08:01 PM roycroft: what do you mean by that?
08:01 PM Tom_L: yeah?
08:01 PM roycroft: does he not say "sorry" enough to live up north?
08:02 PM LeelooMinai: andypugh: And I am saying that you are saying things that imediatelly assume some things and go on the offensive from there.
08:02 PM Tom_L: although i'd rather have them coming from the north instead of the south
08:02 PM roycroft: i don't care where our immigrants come from as long as they're good people
08:02 PM Tom_L: i agree
08:02 PM Tom_L: and legal
08:02 PM andypugh: I don’t come here to fight.
08:04 PM zeeshan: LeelooMinai: Congrads on making a fool of yourself on the internets
08:04 PM zeeshan: your only home! your only reality!
08:04 PM zeeshan: im suprised you're up this early, usually you're active at 3am
08:05 PM LeelooMinai: I am saying that he has typical US-kind of attitude to other people. Some strange misguided starting point for every converstation.
08:05 PM zeeshan: the only person whos strange is you
08:05 PM zeeshan: you dont even leave your home!
08:05 PM zeeshan: i can play the jab game too :)
08:05 PM JT-Mobile: what's up zeeshan
08:05 PM Tom_L: yeah we all can but let's not
08:05 PM zeeshan: fuck i need to finish some parts, we will continue this later
08:05 PM zeeshan: :)
08:05 PM LeelooMinai: RIght, go "full retard" - that will help you:)
08:05 PM zeeshan: hi jt
08:06 PM Tom_L: hah jt showed up at the right time..
08:06 PM zeeshan: http://i.imgur.com/aHCaYLZ.jpg
08:06 PM roycroft: what is a "typical us-kind of attitude to other people"?
08:06 PM zeeshan: i was up north
08:06 PM zeeshan: the black fies killed me
08:06 PM zeeshan: http://i.imgur.com/KXE4Q4F.jpg
08:06 PM zeeshan: wifey came along
08:07 PM * roycroft posits that there is no such thing as "typical american" anything
08:07 PM LeelooMinai: roycroft: Come on, don't pretend that you don't know that US people have tendency to feel they are superior to other countries.
08:07 PM Tom_L: JT-Mobile, see any dolphins down there?
08:07 PM Tom_L: LeelooMinai let it go mkay?
08:07 PM roycroft: some people in this country do
08:07 PM LeelooMinai: Tom_L: I am just answering a question.
08:07 PM zeeshan: jt went to florida? :D
08:08 PM JT-Mobile: Tom_L, didn't see any
08:08 PM JT-Mobile: texas
08:08 PM zeeshan: near the gulf?
08:08 PM LeelooMinai: roycroft: Lots of "some"...
08:08 PM Tom_L: zeeshan, galveston
08:08 PM zeeshan: lol thats right on the gulf
08:08 PM roycroft: it's at the very least disingenuous to ascribe that trait to the majority of folks who live in this country
08:08 PM zeeshan: very cool
08:08 PM zeeshan: looks pretty
08:08 PM Tom_L: you can watch it live
08:08 PM JT-Mobile: I hate black flies but looks like some real purdy contry
08:09 PM Tom_L: on their website
08:09 PM JT-Mobile: country
08:09 PM zeeshan: JT-Mobile: they were going through my bug jacket
08:09 PM zeeshan: and netting
08:09 PM JT-Mobile: damn
08:09 PM zeeshan: gotta respect those resilient bastards
08:09 PM zeeshan: reminds me of LeelooMinai
08:09 PM zeeshan: lol
08:09 PM zeeshan: ok i need to stop
08:09 PM zeeshan: :D
08:09 PM * JT-Mobile goes to load a few things in the trailer
08:11 PM LeelooMinai: roycroft: Do not see how that is the case. It's not like you can have statistics on that. So, in either case you have to rely on experiences and what you see around.
08:11 PM roycroft: it's a pretty prejudicial and pretty insulting thing to say
08:11 PM roycroft: if you intended to offend, you succeeded
08:12 PM CaptHindsight: http://www.ebay.com/itm/Midea-Multi-Tri-Zone-Ductless-Mini-Split-Air-Conditioner-and-Heat-Pump-36k-Btu-/201874605107 closeout prices on mini-splits if anyone needs new AC
08:12 PM CaptHindsight: NOS units
08:18 PM JT-Mobile: zeeshan, starting back home tomorrow
08:22 PM JT-Mobile: seems like every time I take a vacation I get lots of orders and none the week before lol
08:25 PM JT-Mobile: zeeshan, where was that photo from?
08:45 PM X704 is now known as tiwake
09:11 PM gregcnc: do i even dare read this afternoons log?
09:15 PM CaptHindsight: lotsa stuff
09:32 PM Crom: woooo got my viki lcd 20x4 display going...
09:32 PM Crom: now I can work on a DRO
09:33 PM LeelooMinai: Crom: What display is it?
09:33 PM Crom: It's a viki lcd panucutt
09:34 PM Crom: MCP23017 based display
09:34 PM Crom: I2C communication
09:35 PM LeelooMinai: Ok, found it, I see... You want to use it for DRO?
09:36 PM Crom: I have 16x2, 20x2, and the viki 20x4 lcd's the 20x2 is in the computer case and I have to use lcd4linux. the 16x2 and 20x4 are hooked up to arduino's
09:38 PM LeelooMinai: To be honest I would not use those for DRO for myself.
09:39 PM Crom: it's what I have...
09:39 PM LeelooMinai: Right, I mean they are ok for what they are.
09:40 PM LeelooMinai: But the display is LCD with backlight, does not have good resolution, nor character/digit size, etc.
09:41 PM Crom: yeah it's a character display not a graphical
09:41 PM LeelooMinai: For DRO I would either use LED segment, OLED display with custom fonts, or just small screen.
09:41 PM LeelooMinai: Well, it's actually dot matrix - it has character shapes in ROM.
09:42 PM LeelooMinai: If you look closely you will see that there are dots for each "character" in a grid.
09:42 PM Crom: true...
09:42 PM LeelooMinai: The yellow one seems more readable.
09:43 PM LeelooMinai: Still, nothing beats nice oled display:)
09:44 PM LeelooMinai: And segment-led DRO is very readable too, just inflexible - you pretty much have to make a specialized panel for CNC. But that's what Chinese sell a lot for example.
09:44 PM dioz: yo
09:44 PM dioz: i got a better pic of my draft
09:44 PM dioz: can someone tell me what this is?
09:46 PM LeelooMinai: Here's an example of what Chinese sell: http://i.imgur.com/nAD7ARW.png
09:46 PM dioz: transition https://imgur.com/gallery/oVhr5
09:46 PM dioz: my picture is better
09:46 PM dioz: tbh
09:46 PM LeelooMinai: LED segment tech is ancient, but you get big bright coordinates, etc.
09:48 PM Crom: dioz looks like a reducer for hvac
09:48 PM LeelooMinai: dioz: What do you mean "what it is?" - it's a drawing:)
09:49 PM Crom: reducer with offset
09:50 PM LeelooMinai: It's a conduit that makes a transition from one rectangular shape, to another, that is parallel, but shifted on a plane and smaller...
09:51 PM LeelooMinai: Seems pretty obvious there. The view in the bottom left corner shows you how the planes are offset.
09:52 PM LeelooMinai: rectangles are offset*
09:53 PM dioz: Crom: you are correct
09:53 PM dioz: no transverse or longitudal connections thoigu
09:53 PM dioz: pitsberg and slip and drive
09:54 PM dioz: i haven't added the "allowances"
09:54 PM dioz: yo LeelooMinai tell me about bend allowance for 3/16" mild steel
09:54 PM Crom: what's standard seam allowance?
09:54 PM LeelooMinai: A also noticed they marked sides as XL, XR, XF, XB - for left, right, front, back. Not sure if it's a standard way, but I use L R F K and T B are for top bottom - so K for back, so it's not confusable with B for bottom.
09:54 PM dioz: ;)
09:54 PM dioz: Crom: there isn't really a standard so much as a shop standard
09:54 PM dioz: if that makes sense
09:55 PM Crom: in sewing we have 5/8" 17mm
09:55 PM roycroft: do you do that for a living, crom?
09:56 PM dioz: LeelooMinai: when we look at a fitting we draw a single side which includes it's fall (if offset 2 ways)
09:56 PM dioz: so on that elevarion view i'm missing a crucial inatruction foe you
09:56 PM dioz: or else it wiuld all make sense
09:57 PM Crom: roycroft: kinda... we do costumes for shakespeareinthevines.org and we also have a SteamPunk booth we make things for...
09:57 PM dioz: that elevation view would be an inside view of the bqck pannel
09:57 PM LeelooMinai: dioz: Read it from a chart? :) http://www.datametal.com/wp-content/uploads/2014/11/Bend-Allowance-Chart.pdf
09:57 PM dioz: LeelooMinai: touche
09:57 PM Crom: today I was making leather aviator caps
09:59 PM roycroft: oh cool
09:59 PM LeelooMinai: roycroft: You are still "offended? :)
10:04 PM roycroft: you were rude, and since no apology has been proffered i can only assume you meant what you said
10:04 PM roycroft: i do not want to be part of any drama here, so i'll just note that and move on
10:04 PM roycroft: i do not want to discuss it, thank you very much
10:04 PM LeelooMinai: Well, that's... rude.
10:05 PM dioz: haha wow
10:06 PM roycroft: i want to do more leatherworking, but i think i want to get a decent walking food sewing machine before investing much more time/energy into it
10:06 PM LeelooMinai: roycroft: I don't think I was rude, and certainly not to you. It's absurd if you read again. So, I am a bit disappointed, that's all - you seemed helpful and reasonable up to that point.
10:06 PM roycroft: i don't have the skills yet to make 100% hand work worthwhile
10:08 PM dioz: roycroft: check out weirdo wallets. hold on
10:09 PM dioz: lmeme grab a pic
10:09 PM tiwake: s/food/foot/
10:09 PM roycroft: look, i said i do not want to discuss it, but you are pushing
10:10 PM roycroft: you picked a day where i am feeling ashamed, bitter, angry, and disgust about being an american
10:10 PM roycroft: and millions of other americans are feeling exactly the same way that i am right now
10:10 PM roycroft: and you decide to paint our entire nation as a bunch of jingoistic assholes
10:10 PM dioz: https://goo.gl/images/fnND8M
10:10 PM roycroft: no thank you
10:11 PM roycroft: and i shall say no more about it, and implore you not to either
10:11 PM dioz: roycroft: that shit is big around here
10:11 PM LeelooMinai: Ok, I guess it must be some PSTD reaction.
10:11 PM roycroft: nice designs
10:11 PM roycroft: fuck you
10:12 PM dioz: LeelooMinai: what state do you live in?
10:12 PM LeelooMinai: dioz: I think Ontario, let me see.
10:12 PM LeelooMinai: Right, seems to be Ontario:)
10:12 PM SpeedEvil: Denial here.
10:12 PM dioz: ontario is a province
10:12 PM dioz: in the state of canada
10:13 PM LeelooMinai: dioz: Potato/tomato - a sub-division of a country:)
10:13 PM dioz: you're some kind of pro-trudy liberal?
10:13 PM dioz: justin trudy
10:14 PM LeelooMinai: dioz: I am not a person that idenfies with political parties - I find them weird by themselves to be honest.
10:14 PM dioz: safe response
10:15 PM dioz: completely reasonable.
10:15 PM LeelooMinai: Happens to be true though:) I only looked at politics last year, since noticed that people bvehave "weirdly" on internet...
10:15 PM dioz: i think your responses about other peoples political affiliations should be about as much commented on as your own
10:16 PM LeelooMinai: dioz: What "responses about political affiliations"?
10:17 PM dioz: well if you're unable to outline yoir specific political ideology how can you comment on another?
10:18 PM LeelooMinai: dioz: But what comment are you talking about?
10:19 PM dioz: i drew a conclusion
10:19 PM dioz: based on your comment about individuals acting wierd
10:20 PM dioz: it's a supposition that you feel you're normal and others are wierd
10:20 PM dioz: i could probably guess your political affiliations
10:21 PM LeelooMinai: Right, I guess it's probably me - there's nothing weird about US politics recently. Must definitelly be me imagining something.
10:21 PM roycroft: sorry about that
10:21 PM roycroft: i'll just use /ignore for a while to avoid any further drama
10:21 PM tiwake: normal is just an average
10:21 PM roycroft: that was an unwarranted outburst on my part however
10:22 PM dioz: roycroft: i'd still sit in your shop and let you show me how to do things
10:22 PM dioz: it's okay
10:23 PM roycroft: i need to work on the storage drawer design for my lathe stand
10:24 PM roycroft: tooling and stuff are piling up around the machine, and it's getting hard to work there
10:24 PM dioz: machinist chest doesn't work?
10:24 PM dioz: there's tons ar the trade sxhool i'm at
10:24 PM roycroft: i might have a roll-around that i can use temporarily
10:24 PM dioz: i wanna jack 'em up
10:25 PM roycroft: but space is limited around the lathe, so a roll-around would be less than ideal
10:25 PM roycroft: that's why i designed the stand for drawer units to be inserted underneath the machine
11:31 PM AndChat|144384 is now known as skunkworks_
11:35 PM Crom: home again..
11:38 PM Crom: hmmm seems there is a new Marlin out
