01:41 AM Deejay: moin
04:31 AM miss0r: I have a shaft with 44 splines on each end. They are triangular splines. pointy... I turned down the chamfer on the end and scanned it to get a clean picture. https://imgur.com/a/QliKfNM Big OD is 23.67mm small OD is 22.48mm. but with all the rounded valeys and peaks I am having a hard time getting a collect reading. Can any of you guys help me determin what angles this is made with?
04:31 AM miss0r: or is there a special form factor I need to consider?
04:32 AM miss0r: any help at all would be very helpfull
04:32 AM XXCoder: looking
04:33 AM XXCoder: note i dont know those, but i onder if you could reverse engineer it using cad
04:33 AM XXCoder: include a ruler in it, and use it to scale correctlyu
04:34 AM miss0r: I have an 'on screen' protractor. but the resolution I can scan it with is not great enough for a proper reading
04:34 AM miss0r: I would assume the have the same issue with cad
04:34 AM XXCoder: hmm cant do higher resolution?
04:35 AM miss0r: 2 secs - investigating
04:36 AM miss0r: it seems I can double the resolution
04:37 AM miss0r: i'll add a ruler to the photo, 2 secs
04:37 AM syyl: high probability that it is 90°
04:38 AM miss0r: syyl: Indeed. but I can't seem to make the math fit
04:38 AM miss0r: which is why I am in here crying :]
04:38 AM syyl: meh ;)
04:38 AM syyl: do you want to make a scientific approach?
04:38 AM syyl: or just cut the damn profile? ;)
04:39 AM miss0r: well. I want to cut the damn profile, but I want to make damn sure it is an excellent fit
04:39 AM syyl: da a over-pin measurement
04:39 AM syyl: (thats the scientific approach)
04:40 AM miss0r: higher res, with ruler in there: https://imgur.com/a/WrfxHkq
04:40 AM miss0r: syyl: can you be more specific? :D
04:40 AM miss0r: also; I think my smallest pin is 3mm
04:40 AM syyl: drop a small diameter pin in two exactly oposing spline-grooves
04:40 AM miss0r: :D
04:40 AM syyl: and do a measurement with a micrometer
04:40 AM syyl: and then use that in cad to create the real profile
04:41 AM syyl: or do what i do
04:41 AM miss0r: alright. What can I use that measurement for?
04:41 AM syyl: got parametric cad?
04:41 AM miss0r: I have no idea what that means :D I use mastercam
04:41 AM syyl: let the pin diameter and distance drive the sketch for the spline
04:41 AM jthornton: morning
04:42 AM miss0r: jthornton: morning
04:42 AM miss0r: syyl: I can't help but feel I am missing something for that to work
04:42 AM syyl: you only need the number of teeth, the angle of the spline and the pindiameter/distance
04:42 AM syyl: and the OD of the shaft
04:43 AM miss0r: problem is; I don't know the angle of the teeth
04:43 AM miss0r: if I had that, I would just cut the damn splines :D
04:43 AM syyl: thats 90
04:43 AM syyl: just measured it
04:43 AM miss0r: with what, if you don't mind me asking?
04:43 AM miss0r: I can't seem to get a proper reading with my protractor software
04:43 AM syyl: haha
04:44 AM syyl: with a protractor
04:44 AM syyl: against my screen
04:44 AM syyl: as you do
04:44 AM syyl: ah not called protractor
04:44 AM syyl: drafting triangle?
04:44 AM miss0r: basically the same thing.
04:44 AM miss0r: So, what you are telling me is: it is absolutly not 86degrees?
04:45 AM miss0r: (example)
04:45 AM syyl: nobody in his right mind would make something with such a stupid angle
04:45 AM syyl: plus
04:45 AM miss0r: this splines has to handle a pretty sizeable amount of torque, so I would realy like for it to be seated probably
04:45 AM syyl: there is a standard for spline drive profile
04:46 AM miss0r: with refrence to "nobody in their right mind"; this is a '72 land rover...
04:46 AM syyl: oh dang it
04:46 AM miss0r: yeah :]
04:46 AM syyl: good luck, youre on your own.
04:46 AM miss0r: xD thanks
04:46 AM syyl: you know what a real captain does?
04:46 AM syyl: leave the sinking ship before anyone else notices.
04:46 AM miss0r: hehe
04:47 AM syyl: well, i have to eat my words
04:47 AM syyl: the iso standard spline drive profile is 60°
04:47 AM syyl: haha
04:47 AM * miss0r perks up
04:47 AM miss0r: yeah
04:47 AM miss0r: nothing standard about this. When the leyland factory workers were not busy getting high, they were on strike
04:48 AM syyl: all i know about british leyland is what i know from topgear ;)
04:48 AM miss0r: you didn't miss much :D
04:49 AM miss0r: lets just say; clarksson did not exaggerate
04:51 AM miss0r: the problem is, this spline is so tiny, it is hard to do a proper measurement. and I don't have one of those visual comparetors...
04:54 AM miss0r: i'll do a testpeice with a 90degree cut and try to see how well that fits with the mating part
04:54 AM syyl: :)
04:54 AM syyl: do you need to make the male of female part?
04:55 AM miss0r: I need to make a male part
04:55 AM miss0r: the one I have scanned
04:56 AM syyl: ah ok
04:56 AM syyl: thats not that hard
04:56 AM syyl: are you going to use a v-cutter?
04:56 AM miss0r: I have a 90degree included angle "slitting saw" or disc mill - whatever you call it
04:56 AM syyl: or use a normal straight endmill
04:56 AM syyl: and put it at the edge of the part
04:56 AM miss0r: yeah.. that could work as well
04:57 AM syyl: i did a woodchiper spline that way ;)
04:57 AM miss0r: I think that is the way I will go. the diameter on my "slitting saw" is a bit too big, so I would have to rething the shoulder design.
04:57 AM miss0r: with a regular endmill, I can just go up against that shoulder.
04:58 AM miss0r: (it has a radius to it, so it would fit nicely with an endmill)
04:58 AM syyl: :)
04:58 AM Loetmichel: missor: you mean like that? -> http://www.cyrom.org/palbum/main.php?g2_itemId=5471
04:58 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=5474
04:58 AM Loetmichel: :-)
04:59 AM * Loetmichel used one just like that last week to saw off 10mm of an aluminium (7075) block... was behind the gantry side block all the time...
04:59 AM Loetmichel: :-)
05:00 AM miss0r: Loetmichel: This one: https://imgur.com/a/2WG01fR
05:13 AM Tom_L: morning
05:17 AM Loetmichel: miss0r:ah, the good professional ones
05:17 AM * Loetmichel was a bit wary of the selfbiolt one because that sawblade should only have 8krpm, not 24krpm and the blade only holds on a 0,2mm step on the far side ;)
05:18 AM miss0r: :D sounds dangerous
05:18 AM Loetmichel: seen the pics?
05:19 AM SpeedEvil: It's only dangerous if it goes wrong.
05:19 AM Loetmichel: SpeedEvil: the part was also only mounted to the bed with CA glue ;)
05:19 AM Loetmichel: so overheat: VERY bad idea ;)
05:21 AM miss0r: Loetmichel: Yeah, I saw the pictures. Doesn't look too bad. But the speeds you are talking about, I would not want to be anywhere near that
05:21 AM Loetmichel: indeed
05:21 AM * miss0r is doing some very very needed shop cleaning
05:22 AM Loetmichel: problem is that all that holds the blade on the arbor(?) is a 0.2 by 0.2mm lip on that steel bolt i turned down into the arbor.
05:22 AM Loetmichel: (is arbor correct for the pin that holds the blade and is inserted into the ER11?)
05:23 AM miss0r: on the "underside" ?
05:23 AM Loetmichel: yes
05:23 AM miss0r: heh... if it does a small colision, you will have a flying saucer on your hands :D
05:23 AM Loetmichel: i wanted it to be able to cut down to surface of the table
05:24 AM Loetmichel: so the lip had to be smaller than the tooth overhang
05:24 AM Loetmichel: not a flying saucer... a flying sawblade at 24krpm
05:24 AM Loetmichel: ... halflife2 anyone?
05:24 AM Loetmichel: :-)
05:24 AM syyl: we dont go to ravenholm.
05:25 AM Loetmichel: hihi
05:25 AM Loetmichel: exactly
05:25 AM miss0r: Man. That brings back mamories
05:26 AM miss0r: half life 3 is confirmed, by the way
05:26 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=5465 <- thats how i used the old one...
05:26 AM Loetmichel: the new one i made last week was a bit "safer"
05:26 AM miss0r: but since halflife two, I have bought a house, gotten married & had two children... I just don't have the time to play that much anymore :)
05:30 AM * Loetmichel plays Elite Dangerous and lately X4
05:30 AM Loetmichel: i have about 4000 hours in E:D in the last 4 years... ;9
05:31 AM Loetmichel: so much for marriage. lucky me: no children
05:33 AM miss0r: yeah, lucky you
05:34 AM miss0r: My oldest son is 3 years old. Last night I was one uttered latin word from calling an exorcist...
05:34 AM miss0r: but they are alright most of the time
05:39 AM Loetmichel: miss0r: the new slotting saw i used on AL last week: http://www.cyrom.org/palbum/main.php?g2_itemId=17298&g2_imageViewsIndex=1
05:39 AM miss0r: that looks a smidge better
05:40 AM miss0r: welded in?
05:40 AM Loetmichel: nope
05:40 AM Loetmichel: just an M8 bolt turned dwon
05:40 AM Loetmichel: down
05:40 AM miss0r: in that case: eek!
05:40 AM miss0r: :)
05:41 AM Loetmichel: but this time a lot more "flesh" on the outside
05:41 AM Loetmichel: :-)
05:41 AM miss0r: Why not get proper ones?
05:43 AM Loetmichel: that blade is for a small circular saw... i just needed a tool to get the alu shortended down
05:43 AM Loetmichel: so i had blades... and M8 bolts... and a lathe... you get the idea?
05:47 AM Loetmichel: "you are only really a hobby machinist if you catch yourself making a tool to make a jig to hold a part for a machine to make a part the pourpose you have long forgotten by that time" ;)
05:48 AM miss0r: hehehe yeah
05:48 AM miss0r: well, I turned this hobby of mine into a full time job :]
05:48 AM Loetmichel: same here ;)
05:49 AM miss0r: which means; I am now cleaning my shop & being annoyed noone is paying me to do it :D
05:49 AM Loetmichel: when we have customers here at the company and they see me doing "metal origami" by hand they are always in total disbelief
05:50 AM Loetmichel: .. and all because the company has no bending brake ;)
05:50 AM miss0r: hehe
05:50 AM miss0r: I just miss having coworkers to blame for leaving coffee cups around
05:50 AM miss0r: noone here but me.. hehe
05:50 AM SpeedEvil: Get a cat.
05:50 AM SpeedEvil: Blame it for everything.
05:50 AM miss0r: I had a cat. it got eaten by the other cats 'round here
05:51 AM miss0r: alot of "wild" cats roaming the area
05:51 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17130&g2_imageViewsIndex=1 <- that kind of stuff.. and yes, i bend it by hand
05:51 AM miss0r: they are domestic cats, just with no owner. So, they eat whatever they can find - enter my cat
05:51 AM SpeedEvil: miss0r: next project - cat mecha suit.
05:51 AM Loetmichel: only tool is the steel bar with the slot in it below
05:52 AM miss0r: Loetmichel: I understand why they were in disbelief :)
05:52 AM SpeedEvil: Loetmichel: never underestimate the power of a slot and a hammer.
05:52 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17168 <- like that
05:52 AM Loetmichel: SpeedEvil: no hammer
05:52 AM Loetmichel: just hands ;)
05:52 AM miss0r: SpeedEvil: hehe. Another problem; theres ALOT and I mean ALOT of those small tick's in the are. and they are dragged in with the cat and jumps us humans
05:52 AM SpeedEvil: I missed the v-grooves.
05:52 AM SpeedEvil: that is cheating.
05:52 AM miss0r: In my area they are know to have some nasty sicknesses with'em
05:53 AM Loetmichel: SpeedEvil: not V-grooves. 2mm wide rectanglular slots
05:53 AM Loetmichel: makes a slightly rounded corner on the outside
05:53 AM Loetmichel: looks better
05:55 AM Loetmichel: miss0r: thats why domestic cats and dogs here have "flea neck bands"
05:55 AM Loetmichel: they work for ticks, too
05:57 AM Loetmichel: miss0r: it looks a bit like a "slight of hand" trick when you make series of aluminium boxes like these: http://www.cyrom.org/palbum/main.php?g2_itemId=14160&g2_imageViewsIndex=1
05:57 AM Loetmichel: or these brass shielding boxes: http://www.cyrom.org/palbum/main.php?g2_itemId=16348&g2_imageViewsIndex=1
05:58 AM Loetmichel: ... the file is just to get the soldered corners nice and smooth
05:59 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17098&g2_imageViewsIndex=1 <- like that
06:00 AM Loetmichel: you know, like those pizza carton folders in those youtube videos ;)
06:01 AM SpeedEvil: Loetmichel: meanwhile here I am with plywood and wood glue. :)
06:01 AM * SpeedEvil is waiting for the fan for his new 0-22V or so 5A PSU.
06:09 AM Loetmichel: miss0r: i dont see why they are in disbelief though. its 1.5mm aluminum, slottd to 0,75m or 1mm brass slotted to 0,5mm. it bends with virtually no resistance at all
06:10 AM Loetmichel: only tricky part are small flaps that dont want to bend at the right place... hence the second slotted aluminium tool to use as a "come along" ;)
06:11 AM Loetmichel: [12:49] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=17168 <- like that
06:11 AM SpeedEvil: Loetmichel: 1/thickness^3 is a powerful term.
06:11 AM miss0r: indeed :]
06:11 AM Loetmichel: SpeedEvil: indeed ;)
06:12 AM Loetmichel: i do the same with 4mm alu though... needs a bit more muscle, but works just the same ;)
06:13 AM miss0r: bah. i just remembered I have two ISO 50 spindles to regrind/dress tomorrow. I better prepare the equipment
06:13 AM SpeedEvil: miss0r: feeling blue about it?
06:13 AM miss0r: pun intended, I presume :)
06:14 AM miss0r: Nah. I just forgot about it, and its been a while since I used the gear.
06:14 AM miss0r: So, I have a few hours of preparing ahead of me
06:14 AM miss0r: and I wanted to take an early day today
06:20 AM Loetmichel: btw: next 19" 2U front panel on the mill... already running 4 hours, no end in sight ;)
06:20 AM Loetmichel: maybe i shouldnt do 8mm thick alu with tons of pockets on a CNC 6040 router with a 6mm two flute bit...
06:21 AM Loetmichel: ... at least its a new one, MUUUCH less heat in the workpiece than the last time with the dull HSS one ;)
11:33 AM adamj12b: Does anyone have a link to view the past irc chat logs?
11:34 AM Jymmm: !logs
11:34 AM Jymmm: ~logs
11:35 AM adamj12b: !logs
11:35 AM adamj12b: ok not im confused :P
11:35 AM Jymmm: me too, I forget what it is
11:36 AM adamj12b: haha ok.
11:40 AM adamj12b: Tom_L: Tom, Did you have a link to IRC logs?
11:42 AM jthornton: or you can do
11:56 AM adamj12b: jthornton: Thank You. That is exactly what I was looking for.
11:56 AM CNC_Brian: Guy's having a problem getting the parallel port to load in hal. I think because the parport_pc kernel module is loaded.
11:56 AM CNC_Brian: Tried blacklisting parport_pc in /etc/modprode.d/ but its still loaded
11:57 AM CNC_Brian: Any suggestions
11:59 AM adamj12b: jthornton: You wouldn't happen to know how to activate the index-enable signal when orient is called would you? Its a bidirectional signal and i cannot figure out how to tap into it without breaking synchronized motion.
12:03 PM JT-Shop: I've never messed with orient sorry
12:10 PM pcw_home: The fact that index-enable is bi-directional means you need a component with a bidirectional pin to connect to it
12:10 PM pcw_home: This exists: tristate_bit
12:20 PM adamj12b: pcw_home: Thank you! That looks like it will do the job. I have orient working but have to set index-enable manually to reset the encoder.
12:22 PM adamj12b: pcw_home: Second question, what is the update rate on the spindle analog output of a 7i76e? Im sure its no where as fast as the 7i77 that is in the machine, which would explain what I cant get the error as low as I would like on the bench.
12:34 PM pcw_home: 7I77 outputs have about a 2 KHz bandwidth, 7I76 analog out is closer to 200Hz
12:35 PM pcw_home: also analog out + separate direction has issues if you reverse (as might happen at close to 0 speed)
12:37 PM adamj12b: Im not suing the direction output on the 7i76. Just EN and analog to mimic the 7i77 then I use outputs 14 for FWD and 15 for REV.
12:38 PM pcw_home: same issue though, if PID sets direction
12:39 PM pcw_home: (lack of synchronism between speed and direction signals in both 7I76 and drive)
12:41 PM adamj12b: Im trying to understand. Are you saying that by the time the vfd switches direction the pid thinks that happened some time ago?
12:42 PM Tom_L: likely so
12:43 PM adamj12b: on my mill, using the 7i77 to command the VFD, I can lock the spindle my issuing an S200 command and switching directions every 50mS. This is using a second acceleration map of 0.2sec/1000hZ.
12:43 PM adamj12b: by*
12:43 PM adamj12b: BUT, that is not using pid for speed control. just the default FF0 = 1
12:48 PM pcw_home: you should be able to do the same with the 7I76 (fixed analog out + reversing directions)
12:50 PM adamj12b: I will try tonight.
01:40 PM Jymmm: Kinda cool, an inflatable spray booth https://www.youtube.com/watch?v=1HyAq3tLXlw
01:50 PM fragalot: Jymmm: that is indeed quite neat if you would want to start doing on-site stuff
01:57 PM roycroft: the problem with that is that you can only use it once
01:58 PM roycroft: when you deflate it, the overspray that stuck to the walls of the booth will crack and peel off
01:58 PM roycroft: and next time you inflate it you'll have a booth full of crap that will get all over your job when you start shooting paint
02:10 PM fragalot: roycroft: that is what the leafblower is for
02:11 PM roycroft: i don't have anything remotely approaching a proper paint booth environment
02:11 PM fragalot: same
02:11 PM roycroft: i'm resigned to knowing i'll be doing a lot of sanding/buffing and shooting extra coats to get rid of the inevitable crap that gets on the paint job
02:11 PM fragalot: I also don't have the space for that inflatable thing, lol
02:12 PM roycroft: i have a nice side tent for my vw bus
02:12 PM roycroft: it has an external skeleton - the tent fabric hangs from the poles
02:13 PM roycroft: i made a "spray booth" out of 6 mil plastic that i hang from that frame when i need to do spray painting
02:13 PM roycroft: and it works decently, other than the overspray problem
02:13 PM roycroft: most of the overspray lands on the floor, and i do line the floor with paper before starting to spray
02:14 PM roycroft: then i carefully fold up and toss the paper at the end of the job
02:14 PM roycroft: that helps a lot, but i still get little bits of flaked paint that floats around when i start spraying
02:15 PM roycroft: not to mention that it's not ventilated, and even with a good respirator, i can't spray for very long at a go
02:15 PM roycroft: i should get a decent fresh air respirator
02:16 PM gloops: have to be careful if using 2k paints or laquers, only takes a few hours of breathing that crap for permanent damage
02:18 PM roycroft: yes, some of it can be very nasty
02:18 PM roycroft: dupont imron is especially nasty
02:18 PM roycroft: fabulous paint though
02:20 PM roycroft: lots of isocyanates
02:26 PM gloops: what are you making anyway roycroft? got a new product in mind or just general joinery?
02:26 PM roycroft: what?
02:27 PM * roycroft doesn't recall discussing making anything recently
02:27 PM Jymmm: fragalot: yeah =)
02:27 PM gloops: i only caught the last few lines of what you were saying, when i joined - sounded like you might be starting up making something new
02:27 PM Jymmm: roycroft: Hopefully most of the overspray will dry as well as what you are painting
02:28 PM roycroft: oh, no
02:29 PM roycroft: we were discussing inflatable paint booths
02:29 PM Jymmm: gloops: Read the logs starting at 01:40 PM
02:29 PM roycroft: i am making some cabinets for my lathe at the moment, howeer
02:29 PM roycroft: i built an open stand for the lathe, with the intention of adding some drawer units to it later
02:29 PM roycroft: later has finally arrived
02:30 PM gloops: thanks Jymmm - hes just said what it was about though
02:30 PM roycroft: but i'm using a paint roller for them
02:30 PM * Jymmm is trying to figure out the best way to cut a 3" hole in the top of propane tanks
02:30 PM roycroft: i did spray the stand in my vw tent spray booth
02:30 PM roycroft: jymmm: the best way is without explosions
02:31 PM Jymmm: roycroft: They are all been thru the fire and the valves have been removed since Decemeber
02:31 PM roycroft: oh, they're quite unlikely to explode then
02:32 PM Jymmm: If they didn't explode in forest fire, they aren't going to now.
02:32 PM roycroft: use a hole saw
02:32 PM Jymmm: What kind/type of hole saw you think?
02:32 PM roycroft: stuff a plug in the valve hole and use that for the pilot drill
02:32 PM roycroft: i don't think you'd need carbide for a propane tank
02:33 PM roycroft: although a carbide one would last longer, assuming you have several to do
02:33 PM Jymmm: at least three,
02:33 PM roycroft: carbide hole saws are not expensive
02:33 PM Jymmm: Going to thry and turn them into mini pellet typs stoves
02:34 PM roycroft: but the're normally not stocked at big box home improvement stores
02:34 PM Jymmm: or chimenia's (sp?)
02:34 PM roycroft: for only three tanks, a standard bi-metal hole saw would probably suffice
02:35 PM roycroft: i'd try to use a drill press for it
02:35 PM roycroft: hand holding 3" hole saw while drilling through steel is not fun
02:36 PM * roycroft has done that to drill several 3" holes through 0.120" steel, and wished he had a mag drill the whole time
02:36 PM Jymmm: Yeah, and no side handle on the drill either =(
02:36 PM roycroft: don't even try if you don't have a side handle
02:36 PM roycroft: unless you enjoy going to the er to get your wrist fixed
02:36 PM gloops: i did a plate with a 3 inch core drill the other week in cordless drill, about 10 minutes
02:37 PM jdh: plasma cutter!
02:37 PM gloops: you can get a bit more chew here and there wagging the drill about
02:37 PM Jymmm: jdh: I wish
02:37 PM jdh: yes, buy one
02:38 PM Jymmm: Is there such a thing as a plasma/welder combo?
02:38 PM roycroft: lunch time
02:38 PM roycroft: yay
02:40 PM Jymmm: Well, this doens't look agressive at all... https://www.amazon.com/Makita-714085-Carbide-Hole-3-Inch/dp/B0007ZKWSI
02:40 PM fragalot: those last about one hole at work
02:40 PM fragalot: mainly because they get dropped
02:41 PM Jymmm: gloops: What hole saw did you use?
02:43 PM gloops: just an old steel one, it not a struggle or anything with a hand drill, just steady
02:43 PM gloops: https://www.ebay.co.uk/itm/Hole-Saw-Two-Metals-HSS-Core-Bit-Circle-Cutter-Hole-Saw-all-Sizes-with-Drill-Bit/302906398143?
02:44 PM gloops: that type of thing, better quality though
02:45 PM Jymmm: gotcha
03:17 PM Deejay: gn8
03:19 PM Tom_L: 3" hole saw will take some HP to drill
03:27 PM jthornton: and slow rpm
03:30 PM Tom_L: you could send a 3" cannon ball thru it
03:36 PM Tom_L: hmm now they're trying to sell me fusion360..
03:36 PM Tom_L: Your current entitlement is scheduled to expire.....
03:37 PM Tom_L: $350/yr
03:37 PM Tom_L: kinda saw that coming so i never used it
03:39 PM * JT-Shop used to drill 3 1/2" holes in the emitter belt under destroyers with a 1/2 geared drill upside down
03:39 PM Tom_L: fun
03:39 PM JT-Shop: yep, part of the job
03:39 PM Tom_L: break your arm kinda drill
03:39 PM JT-Shop: yep
03:40 PM JT-Shop: geared real slow
03:40 PM Tom_L: yeah i have a smaller one like that
03:40 PM Tom_L: ~150rpm maybe?
03:40 PM JT-Shop: we used to have to drill holes in some crappy places lol
03:40 PM JT-Shop: something like that
03:43 PM Tom_L: i wish i had the ctk for mine so i could make decent dialog boxes for the macros
03:44 PM JT-Shop: ctk?
03:44 PM Tom_L: i think that's what it was called..
03:44 PM roycroft: that's one of my three major problems with fusion360
03:45 PM roycroft: it's free for now, for limited use, but almost guaranteed to be not free in the long term
03:45 PM roycroft: the other two problems being that it requires calling home and storing things in the cloud, and using a proprietary file format
03:45 PM roycroft: the latter would not be so big an issue if it weren't for the first two
03:46 PM Tom_L: JT-Shop similar to the toolkit you used to make your screens
03:48 PM gloops: i think you can renew the amateur license? so long as earning under 100k, tell them your backs gone you arent working
03:48 PM Tom_L: Smartcam Customization Toolkit
03:53 PM JT-Shop: ok
03:54 PM Tom_L: i have some files created by it but don't have the ability to create new ones
03:54 PM Tom_L: not helpful.
03:55 PM XXCoder: turn one of yours into monstority with tons parts ;)
03:57 PM XXCoder: honestly dunno
04:05 PM jthornton: for hole ops I don't bother with a cad/cam program
04:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate1.jpg
04:07 PM Tom_L: for those i did
04:08 PM jthornton: I use my mill G code generator for all my hole ops
04:08 PM Tom_L: yeah i remember that
04:09 PM jthornton: spot, drill, counter sink, tap, and more I think lol
04:10 PM Tom_L: do you rigid tap?
04:10 PM jthornton: yea
04:10 PM jthornton: I could program it to do thread milling...
04:10 PM Tom_L: i got my cam post to do that pretty well
04:11 PM Tom_L: now the macro does the thread milling as a helix
04:12 PM Tom_L: i think i want to change the peck cycle from the G83 to G73 though
04:12 PM Tom_L: at least try it
04:14 PM jthornton: G74 Left-hand Tapping Cycle, Dwell
04:14 PM jthornton: I wonder what they mean by left handed?
04:15 PM Tom_L: cool, i just tried the macro with TPI as a negative and it creates it from the top down
04:17 PM Tom_L: i need to revese the Z leadin move for it though
04:17 PM Tom_L: easy enough
04:18 PM Tom_L: jthornton, probably for left hand taps?
04:20 PM Tom_L: it's not in 2.7
04:20 PM Tom_L: jthornton, counterpart to G84
04:21 PM Tom_L: don't understand why you would have dwell on a tapping cycle though
04:22 PM Tom_L: maybe to create a relief pocket on a lathe?
04:22 PM Tom_L: no idea
04:24 PM Tom_L: looks like it's intended more for lathe
04:47 PM JT-Shop: a lathe would not use a floating tap holder
04:47 PM JT-Shop: at least not that I've ever seen
05:02 PM Tom_L: true
05:02 PM Tom_L: then explain the dwell to me ?
05:03 PM JT-Shop: if I could explain that I'd fix the docs so they are understandable...
05:03 PM Tom_L: hah
05:03 PM Tom_L: the one was added in 2.8.. who added it?
05:03 PM JT-Shop: dunno
05:04 PM Tom_L: just added lefthand threads to the macro
05:05 PM Jymmm: Tom_L: You should toss them up on github
05:05 PM Tom_L: i could get fancy and do double lead threads etc but i'm not gonna
05:05 PM Tom_L: too rare
05:05 PM Tom_L: Jymmm nobody else uses smartcam
05:06 PM Tom_L: nobody i know anyway
05:06 PM Jymmm: Tom_L: I'm sure others do, like like we both use DOS still =)
05:07 PM Tom_L: i could put them on their forum but meh..
05:08 PM Jymmm: Tom_L: But on github, you have rev control, and ppl can fork them to their repository
05:08 PM Jymmm: I'm so tired of bookmarking something, then gone months/years later
05:12 PM CaptHindsight: Jymmm: you know you need a pair https://youtu.be/SyHixtwT6Zs?t=58

05:22 PM Jymmm: CaptHindsight: Eh, I loked the lego blocks and the coating
05:22 PM Jymmm: liked*
05:26 PM jthornton: Tom_L: the dwell is to let the spindle stop
06:34 PM tiwake: think I should go to this? https://www.d2p.com/2019-grapevine-manufacturing-trade-show
06:49 PM CaptHindsight: tiwake: it's mostly small and small-medium size shops showing their services
06:50 PM CaptHindsight: the one around here is in early May
07:00 PM mozmck: Neat - that is just d2p show is just down the road from me. I might have to go to that.
07:01 PM mozmck: oops - bad grammer as I changed thoughts mid-stream.

07:29 PM CaptHindsight: tiwake: you can look all the exhibitors up at the website
07:30 PM CaptHindsight: tiwake: i only go since it's a short drive and beer is usually free on the first day
08:31 PM tiwake: CaptHindsight: never been to any machining/manufacturing shows/conventions in texas
08:31 PM tivoi: hi all
08:36 PM CaptHindsight: tiwake: not a very elaborate show, small booths, sample parts, some 3d printers, you can browse the exhibitor list and see more from all their websites
08:37 PM * flyback bites MarcelineVQ
08:37 PM flyback: CANUCK
08:37 PM flyback: eh?-hole!
08:37 PM CaptHindsight: the salespeople are just looking for jobs from you, it's not like the big shows with lots of demos and chitchat
08:37 PM tiwake: CaptHindsight: are there any big shows in DFW?
08:38 PM tiwake: I don't really know where to look
08:38 PM CaptHindsight: Chicago, Atlanta, Las V, and NYC
08:38 PM CaptHindsight: i guess it's the biggest show in your area
08:39 PM tivoi: @PCW how to buy 7i95
08:39 PM tiwake: I'd rather not go to shitcago
08:39 PM CaptHindsight: shootcago
08:39 PM tiwake: I guess oaklahoma city is about the same distance
08:39 PM tiwake: from me
08:40 PM CaptHindsight: https://www.tradefairdates.com/Fairs-Texas-R3206-T2-S1.html
08:40 PM CaptHindsight: https://www.tradefairdates.com/Houstex-M2842/Houston.html
08:40 PM CaptHindsight: ^^^
08:41 PM tiwake: hmm
08:41 PM CaptHindsight: bbl, train
08:42 PM tiwake: houston is a bit too far away
08:42 PM tiwake: 8 hour drive
08:43 PM jdh: c'mon, texas guys drive 8 hours across their ranches
08:43 PM tiwake: sure, in their tractors too
08:43 PM tiwake: I'm just broke is all
09:08 PM roycroft: texans don't drive tractors
09:08 PM roycroft: their national vehicle is the f150
09:08 PM roycroft: they have a special texas version of that pickup with a single-position accelerator - floored
09:22 PM hazzy-m: jdh: I used to have a truck like that too
09:23 PM hazzy-m: roycroft: you think of texans driving fast? I think of them driving on the sholder at 20mpg in a 75mph zone, lol
09:24 PM tiwake: heh, some of them yeah
09:24 PM hazzy-m: and when the light turns green they drink a beer or dow before starting to move
09:25 PM roycroft: my experience driving in texas is that all texans drive 75mph no matter what
09:25 PM roycroft: and the freeways, at least around dallas, are at the same level as the other roads
09:25 PM roycroft: if there's a traffic jam ahead, just exit at 75mph
09:25 PM roycroft: no worries about whether there's an exit ramp or not
09:25 PM roycroft: just exit
09:25 PM hazzy-m: hahaha. that is true
09:26 PM roycroft: dallas is also surrounded by giant boots
09:27 PM roycroft: the freeways make up an effective beltway that goes around the city
09:27 PM roycroft: and there are a half dozen or so boot stores right next to the beltway
09:28 PM roycroft: all of which have ~40foot tall boots on their property
09:29 PM SpeedEvil is now known as Guest78679
09:34 PM Tom_L: roycroft, their trucks are always black too
09:51 PM Wolf__: I thought all texas vehicles are required to be white
09:51 PM Tom_L: it was an observation i made several times going to galveston
09:51 PM Jymmm: Wolf__: WTF you are stoooopid, they are required to have bull horns on the hood.... DUH <rolls eyes>
09:52 PM Wolf__: bull horns isnt a color...
09:52 PM Tom_L: i also noticed the cops sit in the parking lots way off the access roads running radar
09:53 PM Jymmm: Wolf__: http://img0062.psstatic.com/112476458_rat-rod-real-steer-bull-cow-texas-long-horn-car-truck-.jpg
09:53 PM Tom_L: but it doesn't seem to affect the flow of traffic
09:54 PM Jymmm: Eeeeesh, it must be FIX EVERY HEATER YOU HAVE MONTH
09:54 PM Tom_L: improved the macro
09:56 PM Jymmm: Tom_L WOOHOO, it serves beer now???
