01:32 AM roycroft: which is why the are being retired
02:27 AM Loetmichel: roycroft: depends. the 747 is to big for MOST airlines. some still have routes where they can fill that thing
02:27 AM Loetmichel: and if you can fill it its cheap
02:28 AM Loetmichel: cheaper than payments for an A380 anyways
05:55 AM Loetmichel: *grrr* still handsoldering of 32 pin 0.5mm pitch FFC connectors... MAN my eys get worse every year... or that stuff gets tinier every year. Or both. :-(
07:04 AM Tom_L: roycroft, will it be replaced with piper cubs?
07:08 AM Tom_L: the can park em next to the concorde
07:53 AM * Loetmichel doesnt think thats bad at all for soldering a 0.5mm pitch FPC connector to a PCB by "tactile feedback" and checking with a big magnifying glass afterwards... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17916&g2_imageViewsIndex=1
07:54 AM Loetmichel: ... especially with THAT soldering iron ;)
09:19 AM jymmmm: Good morning
09:20 AM jymmmm: Loetmichel: microscope investment is in your future
09:21 AM Loetmichel: already here
09:21 AM Loetmichel: i just dont like soldering under it
09:21 AM Loetmichel: not enough room
09:22 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17484&g2_imageViewsIndex=1
09:23 AM jymmmm: gotcha
09:24 AM jymmmm: Loetmichel: can't you change a lens to get more room r something?
09:24 AM jymmmm: or*
09:25 AM Loetmichel: na, even at minimum zoom its to close for comfort to the soldering iron
09:25 AM jymmmm: Loetmichel: cnc soldering iron
09:26 AM jymmmm: Anyone need a 12vdc@60A PS?
12:05 PM jymmmm: Can anyone think of a connector that is good for multiple parallel connections?
12:12 PM jymmmm: Hmmm, never saw these before, I guess for screw terminals... https://uk.rs-online.com/web/p/blade-terminals/1641460/
12:19 PM Tom_L: Loetmichel, what power is your mocroscope?
12:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/scope/scope2.jpg
12:19 PM Tom_L: 7 x 45 zoom
12:47 PM Loetmichel: Tom_L: i have honestly no ide
12:47 PM Loetmichel: i think 10 to 40 (for objectives revolver) and a bit of zoom on top
01:54 PM jymmmm: JT-Shop: what was that thing you mentioned a was back to reduce current on an AC motor... demand something relay?
02:00 PM roycroft: you can reduce it a lot by unplugging it
02:08 PM jymmmm: OH this looks like a bad idea... https://www.ebay.com/itm/BATTERY-TERMINAL-CONNECTOR-CLAMP-QUICK-RELEASE-ADJUST-DISCONNECT-new-tool-less/183467298209
02:17 PM andypugh: JT-Cave: https://hackaday.com/2020/07/23/appeasing-chicken-tastes-with-3d-printing/
02:19 PM andypugh: Jymmm: They look better quality than the more common: https://www.ebay.com/itm/193265043253
02:36 PM roycroft: but how do you know how a chicken tastes while it's still alive?
02:37 PM jymmmm: andypugh: True =)
02:43 PM JT-Shop: jymmmm, I think your confused about something
02:44 PM jymmmm: JT-Shop: True, I just cna't recall the thing you mentioned is all, "not demand" but something else
02:45 PM JT-Shop: a potential relay?
02:45 PM JT-Shop: andypugh, interesting... we make chicken furniture from logs and stuff
02:47 PM jymmmm: JT-Shop: YES, thank you =)
03:28 PM likevinyl is now known as Guest37072
04:53 PM jymmmm: Has anyone heard of or used flux SPECIFICALLY for aluminum? Seems to only be availabel from Indian or Russia
05:05 PM roycroft: argon is my flux :)
05:43 PM robotustra: I got such flux
05:43 PM robotustra: ะค61A
05:44 PM robotustra: for soldering aluminum wires
05:44 PM robotustra: this one is low temperature like 180-250 C
05:45 PM robotustra: and there is a high temperature brazing aluminum rods with flux
05:46 PM robotustra: https://www.youtube.com/watch?v=n1njyuPBIH0 for instance
05:47 PM robotustra: or this one https://www.youtube.com/watch?v=WU91tREUqhU
06:02 PM jymmmm: This is actual flux, not a rod... https://www.ebay.com/itm/Flux-for-low-temperature-soldering-of-aluminum-Made-in-Russia/253517448373
06:03 PM jymmmm: https://www.youtube.com/watch?v=8esfonbxuhk
07:32 PM veegee: Today is computer rotation day
07:33 PM Tom_L: you spin it like a top?
07:33 PM veegee: When a new server arrives, another one gets shifted to my "gaming pc" role
07:33 PM XXCoder: no they swap computers like tires on car
07:33 PM Tom_L: gaming... pfft
07:34 PM Tom_L: cad maybe
07:34 PM XXCoder: old server gets server role again, and current server becomes new old server
07:34 PM veegee: So now I have a 32 core threadripper with 128GB RAM
07:34 PM veegee: as a gaming computer
07:34 PM veegee: it used to be used for trade surveillance, billions of records per day
07:35 PM veegee: now reduced to the measly role of running a video game
07:35 PM XXCoder: man
07:35 PM XXCoder: your old gaming one must kick my pc easily
07:35 PM veegee: It has a 1080Ti
07:36 PM veegee: no intel crap in my personal rack. It's all EPYC and threadripper and tape libraries and SAS JBODs
07:37 PM veegee: no interconnect running slower than 10Gbit/s
07:37 PM veegee: mostly infiniband FDR at 56 Gbit/s between servers
07:37 PM XXCoder: man dunno what to do now lol
07:37 PM veegee: all fiber and direct attach copper
07:37 PM XXCoder: just got laid off today
07:38 PM XXCoder: crazy system. but then it had to process billion records
07:38 PM Tom_L: :(
07:38 PM veegee: this one is my personal rack
07:38 PM veegee: so not used for that purpose
07:38 PM Rab: XXCoder, sorry to hear that!
07:38 PM XXCoder: tom they working on more jobs and they will rehire if they win some bids. fun!
07:38 PM veegee: wait weren't you doing the machining?
07:39 PM XXCoder: yep. jobs numbers crashed HARD and company got really bad news of even more parts cut
07:39 PM XXCoder: and im one of less valuable machinist
07:39 PM veegee: where do you live?
07:40 PM XXCoder: tacoma, wa
07:40 PM Tom_L: my kid got an inverview today
07:41 PM Tom_L: the company had just laid off some recently but one of the night shift OD'd yesterday and they need that spot filled
07:41 PM XXCoder: yeah? hope he gets it
07:41 PM veegee: wait what
07:41 PM veegee: OD'd as in overdosed on something?
07:41 PM XXCoder: someone died? jeez
07:41 PM Tom_L: yes
07:41 PM XXCoder: vee yep
07:41 PM veegee: damn, hope he's alright
07:41 PM Tom_L: it's the company my bud had and sold but he still does stuff for them
07:42 PM XXCoder: yeah hope his coffin fits well. od usually means death
07:42 PM Tom_L: i was out to see him yesterday helping him with one of his machines he bought back from them
07:42 PM veegee: I do drugs like a fucking champion by the way
07:42 PM Tom_L: live hard, die young
07:42 PM XXCoder: i dont do legal drugs, my body dont always react well with them, and sometimes doesnt even react
07:42 PM veegee: no not alcohol or any of that toxic stuff
07:43 PM veegee: mostly clean stuff, like lab grade opioids ;)
07:43 PM veegee: and amphetamines
07:43 PM veegee: but always very carefully in precisely measured doses
07:43 PM XXCoder: i only do cdb. it helps a lot on muscles around back paim
07:44 PM XXCoder: vee I just was reading about microdosing using nose spray. pretty cool
07:44 PM veegee: yeah I heard that, I gave some to my mom, she said it gave her a headache and didn't help with back pain
07:44 PM XXCoder: magic mushroom stuff using nose spray
07:44 PM veegee: she refuses to take low dose opioids
07:44 PM XXCoder: it doesnt on direct bone pain. but man cdb does magic on muscles around it
07:44 PM XXCoder: i can move well now. used to lock up all times due to pain
07:45 PM veegee: well that's good
07:45 PM veegee: I can't smoke anything, my lungs don't like any kind of irritation
07:45 PM veegee: one puff of a joint and I go into a violent cough
07:46 PM XXCoder: damaged lungs here yeah i avoid smoking anything.
07:46 PM veegee: On the other hand, I'm not prone to addiction (genetically tested and verified) so that explains a lot
07:46 PM veegee: but I never smoked or did anything to damage my lungs, they're just like that
07:46 PM XXCoder: heh im pretty sure I am. thats why I dont use anything addicting
07:48 PM veegee: All the mainstream drugs suck
07:49 PM Tom_L: anyway, i hope you find something to do soon
07:49 PM XXCoder: drug hipser?
07:49 PM veegee: I mean like alcohol, coffee, cigarettes
07:49 PM XXCoder: thanks. though first month ill probably relax a little. got money from my frankly oversized pto
07:49 PM veegee: alcohol is highly hepatotoxic, coffee is useless and gives you a headache when you quit, cigarettes obviously
07:49 PM XXCoder: i very rarely go on vacation or sick so it barely got dented across years
07:50 PM Tom_L: you shouldn't take it if you plan to file unemployment
07:50 PM veegee: do you have a social safety net like unemployment?
07:50 PM XXCoder: yep
07:50 PM veegee: we have that here in canada, super easy to get it
07:50 PM Tom_L: if you take pto it may disqualify you for UE
07:50 PM veegee: government doesn't try to stop you like they do in the usa
07:50 PM Tom_L: you might check on it before you do anything
07:51 PM Tom_L: here you state it's due to the virus and they don't even make you look for work
07:51 PM XXCoder: tom they said to make a claim with all hours of pto as well as full time week this week
07:51 PM veegee: where are you located?
07:51 PM XXCoder: next week claim will be zero hours worked
07:51 PM XXCoder: veegee: said tacoma, wa :)
07:51 PM veegee: no I was asking Tom_L
07:52 PM Tom_L: i'm in ks
07:52 PM veegee: going to ignore the assumption that the rest of the world knows what that is
07:52 PM veegee: but I'm going to guess kansas
07:52 PM XXCoder: 187 hours lol if I didnt get seriously dizzy and unable to work for a week and couple days on different weeks, it'd be over 200
07:52 PM Tom_L: yes
07:55 PM Tom_L: anything to look out for on an index head?
07:55 PM Tom_L: i don't need a super good one
07:55 PM Tom_L: it's just for hobby purposes
07:55 PM veegee: for a rotary table?
07:56 PM Tom_L: yeah
07:56 PM XXCoder: what type? facemill?
07:56 PM XXCoder: ah
07:56 PM Tom_L: horizontal / vertical
07:56 PM veegee: Yeah I had the same question actually
07:56 PM Tom_L: been looking at the cheap ones on ebay or amazon
07:56 PM veegee: I have a vertex 12" rotary table
07:56 PM Tom_L: i need a fairly small one
07:56 PM Tom_L: like 5" 3 jaw on it
07:57 PM XXCoder: got link? curious
07:57 PM Tom_L: i see no reason to power it since my cad cam doesn't do full rotary
07:57 PM veegee: XXCoder https://www.amazon.ca/Vertex-Horizontal-Vertical-Rotary-Table/dp/B00IZ9IQPE
07:57 PM veegee: The big version of that
07:58 PM XXCoder: ahh ok
07:58 PM veegee: It's so damn heavy. I gained muscle mass over the past few months since I started this machining hobby
07:58 PM Tom_L: https://www.amazon.com/slp/dividing-head/wdz35zena8677rv
07:58 PM veegee: just from carrying around heavy equipment. It weighs over 100 lbs
07:58 PM Tom_L: i was looking at the top one there
07:58 PM XXCoder: yeah i can never start my own machinist company
07:58 PM XXCoder: I cant lift worth shit with my shitty back
07:58 PM Tom_L: veegee, my bud has a 10" kurt vise :)
07:59 PM Tom_L: it's damn heavy
07:59 PM veegee: yeah and that damn vise, I have the 6" kurt vise
07:59 PM XXCoder: tom yea if you go *really* cheap I would recommand rebuild it even as new
07:59 PM XXCoder: because there be chips there
07:59 PM Tom_L: yeah i figured as much
07:59 PM veegee: I have a gantry crane and an engine crane beside the mill for lifting these things on and off the table
08:01 PM veegee: Tom_L do you know which model the 10" vise is? I'm curious
08:02 PM Tom_L: no
08:02 PM Tom_L: he seldom uses it
08:02 PM veegee: I have this one: https://www.amazon.ca/Kurt-DX6-opening-Height-16-810/dp/B01LXAUU7J
08:02 PM Tom_L: right now he's pulling all the boards out of one of the vmc's to send in
08:02 PM veegee: I don't understand all the hate around it, I actually really like it
08:03 PM Tom_L: who hates it?
08:04 PM veegee: The average review being 4 stars. But I see it now, it's random 1 star reviews with a comment like "Has held up very well. Been in use for a year with no problems other than some of the paint flaking off."
08:04 PM veegee: idiotic reviewer
08:04 PM Tom_L: idiots
08:05 PM Tom_L: i got a shars 4" for my mill and i'm pretty happy with it
08:05 PM XXCoder: i can *barely* lift 6" kurt vise. it kurts to lift
08:05 PM Tom_L: i didn't need to spend the extra for a kurt
08:05 PM XXCoder: of course I use shop car to move it around
08:05 PM Tom_L: the 4" costs more than the 6"
08:06 PM Tom_L: 6 is more commin is why probably
08:06 PM Tom_L: common
08:06 PM XXCoder: probably tons used too
08:06 PM XXCoder: shop have tons 6" and only maybe 3 10" and 2 4"
08:24 PM robotustra: what mills are you using? broke one mill, but finally did t-nuts
08:27 PM robotustra: now I know - do not put end mill smaller than 6 mm in the manual mill
08:39 PM Tom_L: cutters?
08:40 PM Tom_L: i use from 1/32nd up to 3/8
08:40 PM Tom_L: with a 1" insert cutter and a flycutter
08:41 PM robotustra: what is the power of your mill?
08:41 PM Tom_L: 600w approx
08:41 PM robotustra: 1 hp?
08:41 PM Tom_L: oh hell no
08:42 PM robotustra: 1 hp = 740 W
08:42 PM Tom_L: the steppers are plenty beefy, the spindle sucks
08:42 PM Tom_L: it's a sherline spindle
08:43 PM Tom_L: that's why i 'water cooled' it
08:43 PM Tom_L: otherwise i'd probably have burnt it up by now
08:43 PM robotustra: I mean that I can put smaller endmills in the mill only when it will be cnc, for manual operation I don't feel when small endmills bends
08:44 PM robotustra: I burned 10A fuse today, when the mill stacked
08:44 PM robotustra: but didn't brake 6mm carbide mill
08:44 PM robotustra: the endmill is intended for aluminum but it make nice chips on steel
08:45 PM robotustra: this one https://www.ebay.com/itm/283551985420
08:46 PM robotustra: it cuts steel very easily, I'm not sure if it needs lubricant or cooler - I put some oil when it start squick - and that's it
08:46 PM robotustra: it did the work pretty good
08:48 PM Tom_L: you're better off using 4 flute in steel
08:49 PM Tom_L: 2-3 flute in aluminum since the chips are bigger
08:49 PM Tom_L: that's pretty cheap for a carbide cutter
08:51 PM robotustra: when I used 4 flutes - it chipped tips of the flutes
08:51 PM robotustra: I don't know what I'm doing wrong
08:53 PM robotustra: https://imgur.com/a/UV36U1H
08:53 PM robotustra: may be because of chips overcut
08:54 PM robotustra: I really don't know, may be it it not intended for slot cutting
08:57 PM robotustra: https://imgur.com/a/cxeB96U
08:57 PM robotustra: here is the problem
08:57 PM robotustra: 3 of 4 flutes chipped
08:58 PM robotustra: but when I do side milling - everything works ok
09:06 PM robotustra: where muricans buy endmills?
09:09 PM Tom_L: onlinecarbide.com or lakeshorecarbide.com
09:09 PM Tom_L: or locally
09:10 PM robotustra: what is better to use for cast iron milling?
09:10 PM Tom_L: i've not cut much if any cast
09:10 PM Tom_L: it's pretty soft isn't it?
09:11 PM robotustra: don't know, I got cast iron nuts from mcmaster - it looks pretty dense
09:11 PM robotustra: but I can file it
09:12 PM Tom_L: crappy dirty stuff isn't it?
09:12 PM Tom_L: travers.com is another supplier
09:12 PM robotustra: I don't know how chineese makers do their acme nuts for g0704, but mcmaster nuts has no lashback at all
09:13 PM robotustra: at least I don't feel it by hands
09:13 PM robotustra: thanks
09:15 PM robotustra: https://i.imgur.com/6IRwmSO.jpg
09:16 PM robotustra: tomorrow I have to fit them to size
09:19 PM roycroft: i just did something i've never done before - i made some boards straight that were wider than my jointer
09:19 PM roycroft: i've always ripped wide boards down to the width of my jointer, made them straight, then glued them back together
09:20 PM roycroft: but i did not want the glue lines this time, and although a good glue joint is as strong or stronger than the wood, not all glue joints are perfect, and i wanted this to be as strong as possible
09:21 PM roycroft: it was so easy to do, though, that i'm kicking myself for nver having tried it before
09:25 PM robotustra: how did you make them?
09:25 PM robotustra: router?
09:30 PM roycroft: i took the guard off the jointer, joined a 6" wide swath in a single pass, then made a carrier for my thicknesser out of melamine-covered mdf
09:31 PM robotustra: ah ok
09:31 PM roycroft: i ran the board through the thicknesser with the jointed swath riding on the carrier until the opposite side was flat, then flipped it over, removed the carrier, and ran it through until the ridge was cut down
09:31 PM roycroft: it was just too easy
09:32 PM robotustra: doing kitchen?
09:32 PM roycroft: and i've known about the technique for decades, but never tried it
09:32 PM roycroft: i'm building a new workbench right now
09:32 PM roycroft: and i was working on the chop today
09:32 PM roycroft: which is really wide and thick
09:32 PM roycroft: and is the thing that needs to be really strong
09:33 PM roycroft: well the whole bench needs to be strong, but it will be
09:33 PM roycroft: it will probably weigh 350-400kg when i'm done :)
09:33 PM robotustra: it's overkill
09:33 PM roycroft: no
09:33 PM roycroft: it's my hand tooling bench
09:33 PM robotustra: you'll brake you back when you'll move it
09:34 PM roycroft: i'll use technology to move it
09:34 PM roycroft: but the point is, it will not move unless i try really hard to move it
09:34 PM robotustra: my father also wanted heavy workbench an put a sheet steel on th top
09:34 PM roycroft: when i'm hand planing or chopping mortises i waste a lot of my energy because the current bench is absorbing it or moving
09:34 PM Tom_L: for woodworking?
09:35 PM robotustra: and the angle on the edge
09:35 PM roycroft: yes
09:35 PM roycroft: i'm building it out of ash, with some walnut and cherry
09:35 PM robotustra: no for general purpose in the garage
09:35 PM roycroft: but it's mostly ash
09:35 PM Tom_L: vise on the end?
09:35 PM Tom_L: holes down the middle for clamping
09:35 PM roycroft: a wagon tail vise and a leg vise on the front left
09:35 PM roycroft: the top will be two pieces
09:36 PM robotustra: I have small workbench, ache top
09:36 PM roycroft: with a gap in the middle
09:36 PM roycroft: and yes, there will be dog holes
09:36 PM robotustra: 5 cm of thickness
09:36 PM robotustra: I did not fancy workbench as soon as I don't use dog holes
09:37 PM roycroft: https://wnwoodworkingschool.com/class/roubo-bench-with-william-ng/
09:37 PM roycroft: it will look similar to that
09:37 PM Tom_L: what you makin it out of?
09:37 PM roycroft: my bench top will be 12cm thick :)
09:37 PM roycroft: ash
09:38 PM roycroft: which is one of my favorite woods
09:38 PM robotustra: https://i.imgur.com/C6a9VkI.jpg
09:38 PM roycroft: and is ideal for a bench
09:38 PM roycroft: it's strong, it's heavy, it doesn't compress much, it's not very springy
09:38 PM roycroft: and it's purty
09:39 PM Tom_L: what about birch?
09:39 PM robotustra: that's a classical workbench, for carpenters and jointers
09:39 PM roycroft: i use birch for a lot of things
09:39 PM roycroft: but ash is better suited for a workbench
09:39 PM roycroft: and i want my bench to make a statement
09:39 PM Tom_L: i'm not that much into woodworking
09:39 PM roycroft: the grain in the ash will definitely make a statement
09:40 PM robotustra: roycroft, do you do a lot of woodworking?
09:40 PM Tom_L: my bench makes a statement. it won't move
09:40 PM roycroft: yes, a fair amount
09:40 PM Tom_L: 1/2" plate steel
09:40 PM roycroft: and i'm hoping to do it full-time soon
09:40 PM roycroft: i used to have a cabinet shop about 30 years ago
09:40 PM robotustra: for yourself or for sale?
09:40 PM robotustra: oh cool
09:40 PM roycroft: i don't want to do that again
09:40 PM robotustra: I do some fine woodworking too
09:41 PM Tom_L: he's gonna be the 'this old tony' of woodworking
09:41 PM robotustra: but where to get money?
09:42 PM robotustra: I would like to work in my workshop all the day, but who gives me money to live :)
09:43 PM robotustra: it's a dilemma
09:43 PM Tom_L: i'd love to have 2 5k sq ft shops, one wood and the other metals
09:43 PM roycroft: i've always had an interest in japanese shoji screens and other things made with kumiko (the "latticework" in the shoji screens)
09:43 PM veegee: https://www.youtube.com/watch?v=-zHlxeu_yuM "I probably made a few oil companies mad in the previous video, so I probably shouldn't open this box"
09:43 PM roycroft: i've been slowly gearing up to doing that as my retirement buiness
09:43 PM veegee: Definitely not below them to do something like that
09:43 PM roycroft: my job may be ending soon, though - i was planning on working for another 3-5 years before retiring
09:43 PM snakedGT is now known as snaked
09:44 PM roycroft: but if my job ends early i want to do the woodworking business full time right away
09:44 PM roycroft: so i've been accelerating my preparations for that
09:44 PM veegee: I'm incredibly lucky to have what I have
09:44 PM veegee: especially at this age
09:44 PM robotustra: roycroft, what about clients?
09:44 PM veegee: 3,300 sq ft hobby shop
09:44 PM roycroft: i can build a client base when the time comes
09:45 PM veegee: never thought I'd be able to do that at 29 years of age
09:45 PM roycroft: i have a number of people already interested in my stuff when i start cranking it out
09:45 PM Tom_L: it's not hard to do with wood products
09:45 PM roycroft: well the nice thing about wood products is that it's cheap and fast and easy to switch gears if need be
09:45 PM Tom_L: i made a toy box for a niece and had probably 10 ppl wanting one
09:46 PM roycroft: once the basic equipment investment is made changing products is easy
09:46 PM roycroft: and i have built up a pretty good shop over the years
09:46 PM roycroft: the new workbench is the last major investment i need to make before i'm ready to do it for a living again
09:46 PM robotustra: I wander if it's possible to do some metal works for clients
09:47 PM Tom_L: a guy i knew worked at cessna and in his spare time would get a bunch of wood stuff made up and sell it at the mall at christmas
09:47 PM Tom_L: robotustra, probably a completely different group of clients
09:48 PM robotustra: true
09:48 PM robotustra: I need 2 groups of clients
09:48 PM robotustra: "wood" clients and "metal" clients
09:48 PM veegee: roycroft I built a 5'x10' welding table with a 1/4" thick cold rolled steel plate
09:48 PM roycroft: the vise hardware arrived yesterday
09:49 PM roycroft: that was over $700, and i'd been waiting for it since february
09:49 PM roycroft: i have as much again invested in timber, and probably $300-$400 more for timber before i'm done
09:49 PM roycroft: and it's not that the company who make the vise hardware were shut down
09:49 PM roycroft: to the contrary, they're busier than ever
09:50 PM roycroft: when the pandemic hit and the lockdowns started everyone in the universe started woodworking
09:51 PM XXCoder: bah sucks that I still dont have room. I have plenty of time now but no room to setup my cnc router
09:51 PM robotustra: what oil is better to use to lubricate hand mills?
09:55 PM Tom_L: i'd stick with mobile vactra 2 personally
09:56 PM Tom_L: cutters or mill ways?
09:57 PM Tom_L: XXCoder, did you sell your oil?
09:57 PM XXCoder: not yet i was being lazy
09:57 PM XXCoder: planned to post at work
09:57 PM XXCoder: oh well
09:57 PM XXCoder: posting now would make me look desprate or something
09:57 PM robotustra: mill waus
09:57 PM robotustra: ways
09:58 PM XXCoder: you live at wa state?
09:58 PM Tom_L: yeah vactra 2
09:58 PM Tom_L: robotustra, is in Ru iirc
09:58 PM XXCoder: oh little far heh
09:59 PM XXCoder: liter bottles have issue where cap could pop off when shipped
09:59 PM roycroft: not that far
09:59 PM XXCoder: so uncertain how to ship em
09:59 PM roycroft: sarah palin can see robotustra's house from her living room :)
09:59 PM XXCoder: Ru = russia?
09:59 PM XXCoder: ah of course youre right, not far at all
09:59 PM robotustra: I'm in canada, montreal
10:00 PM roycroft: and alaska is the next state north of washington
10:00 PM robotustra: yesterday was exactly 10 years I'm in canada
10:02 PM Tom_L: huh, not sure where i figured you were Ru
10:02 PM robotustra: russian speaking
10:02 PM robotustra: but I'm from belarus
10:02 PM Tom_L: ahh ok
10:02 PM robotustra: belarus != russia
10:03 PM XXCoder: im tempted to immgrate into canada lol back to my grandfather land
10:03 PM XXCoder: but nah
10:03 PM robotustra: but yeah I was born in USSR
10:03 PM robotustra: I lived in USSR almost 20 yeas before it ended
10:04 PM roycroft: well at this point you should at least wait until after the election before making a decision like that, xxcoder
10:05 PM XXCoder: yeah and in my its very hard
10:05 PM XXCoder: you need good job prosects
10:05 PM XXCoder: and im shit on job finding
10:05 PM robotustra: I was thinking to move somehow to USA, but now I'm not sure if I want to do it :)
10:05 PM robotustra: for a number of reasons
10:05 PM XXCoder: no no please come here we need sane people
10:05 PM XXCoder: but then plague center hm
10:06 PM robotustra: I'm just across the border :)
10:06 PM XXCoder: visit if you dare
10:06 PM robotustra: I did couple of times for 1 day
10:06 PM robotustra: Shamplain beach
10:07 PM robotustra: at Plasbourg
10:07 PM roycroft: the border is closed at the moment
10:07 PM robotustra: Plattsbourg
10:07 PM roycroft: and will be for quite some time yet
10:07 PM XXCoder: yep it will stay closed during plague fun special event is going on in usa
10:08 PM roycroft: it looks like we're closer to a vaccine
10:08 PM roycroft: but "closer" means "early next year" instead of "the middle of next year"
10:08 PM robotustra: I think vaccine will not be created
10:08 PM CaptHindsight: border from USA to Canada is closed
10:09 PM roycroft: there are a number of vaccines that are being developed that have promise
10:09 PM robotustra: because I think there were some repetitive cases
10:09 PM roycroft: but even when we have one, it's going to take a year to make enough doses to reach herd immunity
10:09 PM XXCoder: not only that but usa vaccines is likely to cost thousand or more
10:09 PM roycroft: and it's still not known if people will need periodic boosters
10:10 PM XXCoder: even if we usa citzens funded it, company will thank us and give us the finger
10:10 PM CaptHindsight: every 6 months until you die, then every 3 months
10:10 PM roycroft: the real problem is that it doesn't matter if we get a vaccine and vaccinate everyone in the us
10:10 PM robotustra: I can't say 100% but I think there is no vaccine from this plaque
10:10 PM roycroft: we need to vaccinante the entire world
10:11 PM XXCoder: robot there is a vaccine in human testing already
10:11 PM roycroft: there are multiple vaccines being tested already
10:11 PM robotustra: XXCoder, tell me when they pass the test
10:11 PM XXCoder: ok
10:11 PM roycroft: it will be several months before the initial testing is done
10:12 PM robotustra: USA gov fucked up when they told to ppl that they are 78% ready for pandemy
10:12 PM roycroft: and next year at the earliest before one can be made in quantity
10:12 PM CaptHindsight: https://www.bloomberg.com/news/articles/2020-07-20/russian-elite-got-experimental-covid-19-vaccine-from-april
10:12 PM roycroft: let's avoid discussing the political aspects please :)
10:12 PM robotustra: experimental does not mean it works
10:13 PM robotustra: there is no politics in here - we all die, sooner or later
10:13 PM robotustra: :)
10:13 PM CaptHindsight: robotustra: so knowing the Russians, would they be testing since they think it works or to prove it doesn't?
10:13 PM robotustra: of cause they do the investigation
10:14 PM robotustra: but to make a vaccine it usually takes 2-3 years
10:14 PM robotustra: normally
10:14 PM roycroft: yes
10:14 PM robotustra: and what they got now - it doesn't mean that it will work 100%
10:15 PM CaptHindsight: in Russia vaccine test you
10:15 PM robotustra: it's applicable to eveywhere
10:15 PM robotustra: in USA gov test you
10:15 PM CaptHindsight: the old in Russia joke
10:15 PM roycroft: no vaccine is 100% effective
10:15 PM roycroft: nobody expects that
10:15 PM CaptHindsight: now it's flipped :)
10:16 PM robotustra: the original joke was about TV
10:16 PM CaptHindsight: what part of Russia were you from?
10:16 PM robotustra: in reality: Chineese TV watchs murican people
10:16 PM robotustra: I'm from Belarus, Minsk
10:16 PM roycroft: he's not from russia
10:17 PM CaptHindsight: oh sorry
10:17 PM roycroft: he's from the former ussr
10:17 PM robotustra: it's between poland and russia
10:17 PM roycroft: which is different
10:17 PM CaptHindsight: my dad was from near Sevastopol
10:17 PM robotustra: mostly we speak russian in big cities
10:17 PM robotustra: Sevastopol is deeply russian city
10:18 PM CaptHindsight: he left Russia during WWII and didn't go back
10:18 PM robotustra: a lot of people stay in Europe after ww2
10:19 PM robotustra: especially if they didn't have any family
10:19 PM CaptHindsight: most of his family was sent off to Siberia
10:19 PM robotustra: that's too
10:19 PM robotustra: but I think they were sent after he didn't come back
10:20 PM CaptHindsight: he and his brother left the army one night and went across the American lines
10:20 PM robotustra: as a "relatives of enemy of peolpe"
10:20 PM CaptHindsight: stayed in Germany for a bit and then came to the USA
10:20 PM robotustra: ah, that's too
10:20 PM CaptHindsight: his brother stayed in Austria
10:21 PM robotustra: deserter
10:21 PM CaptHindsight: being an ethnic minority there you were useful during war but not after
10:22 PM robotustra: fortunately, I'm not so old to remember all this stuff.
10:22 PM CaptHindsight: nothing to go back to in Russia except Siberia or a firing squad or worse
10:22 PM CaptHindsight: he did go back to visit during the early 90's
10:23 PM CaptHindsight: some family did return to the area
10:23 PM robotustra: I don't follow much what's going on in Eurasia
10:23 PM robotustra: the level of leaving is still low
10:23 PM robotustra: I would not allow myself to buy a mill in belarus
10:25 PM robotustra: here I can afford it
10:25 PM CaptHindsight: I imagine there is lots of old iron there still in use
10:27 PM CaptHindsight: we grew up on hearing old stories about Stalin and Hitler
10:27 PM robotustra: actually, I follow one russian youtube channel, guys buy old machines restore them and do a production
10:27 PM robotustra: like full production
10:27 PM CaptHindsight: pretty much everything that happened in the news was compared to how either of them would have handled it
10:27 PM CaptHindsight: lots of shootings apparently
10:28 PM CaptHindsight: shootings/executions
10:28 PM robotustra: where?
10:28 PM robotustra: ah, that times?
10:28 PM robotustra: now all shooting moved to usa
10:28 PM CaptHindsight: 50's to 80's USA
10:28 PM CaptHindsight: yeah
10:29 PM robotustra: in russia ppl are not allowed to have guns freely
10:29 PM CaptHindsight: Russia and Ukraine boarder is not stable, like Chicago's south side
10:29 PM CaptHindsight: so similar
10:29 PM robotustra: they can, but it's a long process, usually start from hunting guns
10:30 PM robotustra: As soon as I know it's stable except for Krym, and some internal movements in Ukraine
10:30 PM robotustra: I moved to canada as soon as I could
10:31 PM robotustra: because it was pretty evident that after decay of USSR it will be worse
10:31 PM CaptHindsight: I wish my parent would have chosen Canada as well but their sponsor was from the USA
10:31 PM CaptHindsight: parnet/parents
10:31 PM robotustra: you can't move to canada?
10:32 PM CaptHindsight: not now
10:32 PM CaptHindsight: maybe in a year or two
10:32 PM robotustra: it's degrading as usual
10:32 PM robotustra: montreal was a city in 1960-1970
10:33 PM robotustra: now it's something strange
10:33 PM CaptHindsight: actually looking back at Europe
10:33 PM robotustra: nah
10:33 PM CaptHindsight: somewhere actually progressive
10:33 PM robotustra: there is no more Europe
10:33 PM CaptHindsight: and not China progressive, politically progressive
10:34 PM CaptHindsight: yeah like a mess
10:34 PM robotustra: Europe has no oil
10:34 PM robotustra: no natural resources
10:34 PM CaptHindsight: but the passing space ships don't bother stopping so i can't hitch a ride
10:35 PM robotustra: USA is still great
10:35 PM CaptHindsight: small scattered reactors would solve this but SCARY and too many accidents
10:36 PM robotustra: it has some problems like healthcare
10:36 PM robotustra: retirement
10:36 PM robotustra: too hot and expensive in Cali
10:36 PM robotustra: too crowded in NYC
10:36 PM CaptHindsight: small tropical islands in the pacific that have some altitude
10:37 PM robotustra: too many kills
10:37 PM robotustra: possibly
10:37 PM CaptHindsight: i miss NYC from the 70's to ~2000
10:37 PM CaptHindsight: now it's like a big shopping mall
10:37 PM CaptHindsight: in the suburbs
10:37 PM robotustra: So big probability that I'll stay in Canada
10:38 PM robotustra: for the rest of my long long life
10:38 PM roycroft: the climate in northern california is actually very nice
10:38 PM robotustra: btw climate get a bit warmer in here
10:38 PM roycroft: more like oregon than socal
10:38 PM roycroft: but it's still california
10:38 PM CaptHindsight: farming in Canada might be an option
10:38 PM CaptHindsight: and if there is broadband
10:39 PM robotustra: farming robots - that's the plan
10:39 PM robotustra: :)
10:39 PM norias: too many kills?
10:40 PM CaptHindsight: I got an email today from a co in Canada that rebuilds forests
10:40 PM CaptHindsight: looks like they are working on rapid replanting systems
10:40 PM norias: hmm
10:40 PM norias: rebuilt forests
10:40 PM norias: is there a core charge?
10:41 PM CaptHindsight: 20 year deposit
10:42 PM CaptHindsight: build giant bio-reactors that turn sunlight and CO2 into oxygen and cellulose
10:43 PM robotustra: China actually did it
10:43 PM robotustra: in 20 years
10:43 PM robotustra: so I think it's doable in Canada too
10:45 PM CaptHindsight: pop 37M vs 1.2B
10:45 PM CaptHindsight: Canada and the UK could take in all of Hong Kong
10:46 PM norias: so...
10:46 PM norias: i was looking at some tables for fits based on ANSI B4.1 and B4.2
10:47 PM norias: and I noticed, they are all hole basis
10:47 PM norias: when, I've never seen anything actually done on hole basis, it seems everything is shaft basis
10:47 PM CaptHindsight: robotustra: are you on the rainy side or cold side of Canada?
10:47 PM norias: but... I can't find charts for that
10:47 PM robotustra: CaptHindsight, sunny Montreal
10:48 PM robotustra: quebec
10:48 PM robotustra: it's 1/2 of year winter and 1/2 year summer
10:48 PM robotustra: and 270 days a year we have sun
10:48 PM CaptHindsight: robotustra: how does Montreal compare to Ottawa?
10:49 PM robotustra: I was in Ottawa 2 times only
10:49 PM robotustra: I think it's a bit colder in mtl
10:49 PM CaptHindsight: too run down?
10:49 PM robotustra: visited my friends
10:50 PM robotustra: but in the summer it's good everywhere across
10:50 PM CaptHindsight: I've only been from Windsor to Toronto
10:50 PM CaptHindsight: used to drive that way from Chicago to upstate NY
10:51 PM robotustra: I didn't travel much yet, I prefer to stay home and make something than wander around
10:52 PM robotustra: my radius of travel is 2-3 hours on the car
10:52 PM CaptHindsight: I go just about everywhere
10:53 PM CaptHindsight: feel trapped currently
10:53 PM robotustra: if I have a choise to 1) go camping on long weekend or 2) stay at home and build a cnc machine - I'll chose the second option
10:53 PM CaptHindsight: norias: like this? https://www.engineersedge.com/calculators/mechanical-tolerances/ansi-fit-tolerances.htm
10:54 PM norias: CaptHindsight: close
10:54 PM CaptHindsight: heh, i don't like to be home for long
10:54 PM norias: those seem to be hole basis
10:54 PM CaptHindsight: would rather be just about anywhere else
10:55 PM CaptHindsight: norias: so you are looking for non hole fitments?
10:55 PM norias: right, shaft basis
10:55 PM norias: unless I'm way out of whack here
10:56 PM CaptHindsight: shaft not into a hole?
10:56 PM norias: it's basically where is the 0 tolerance on the hole
10:56 PM roycroft: i believe ottawa gets colder on average than montreal
10:56 PM roycroft: winters in ottawa are quite harsh
10:56 PM jymmmm: CaptHindsight: Have you seen anything like this before? https://www.carbuilder.com/images/thumbs/0034772_14-male-spade-terminal-10-way-busbar.jpeg
10:56 PM norias: like, you will see H9 for holes basis tolerances
10:57 PM norias: and h9 for shaft basis
10:57 PM norias: eh. I'm going to sit down and just read the entire standard, it seems
10:58 PM robotustra: possibly it will be better for future
10:58 PM robotustra: I also have to get some knowledge in machining
10:58 PM robotustra: and standards
10:59 PM robotustra: and industrial metals and alloys
10:59 PM norias: cool
11:01 PM robotustra: and I definetly have to build power feed to the mill
11:01 PM robotustra: becsue it's too annoying to stand and rotate handle
11:01 PM norias: haha
11:01 PM norias: you're telling me!
11:02 PM robotustra: but at the same time you feel like endmill bites the metal
11:03 PM norias: yeah
11:04 PM norias: pros and cons
11:04 PM robotustra: I think I would have a feeder which do constant torque on handles to not break the mills
11:04 PM norias: the further you get from the process, i feel like, it gets more interesting
11:05 PM robotustra: one more problem - steel chips heavier to remove with vacuum cleaner
11:05 PM robotustra: they don't fly like aluminum
11:06 PM norias: i've been thinking, a little, about the vibrations mechanics of non-cylindrical end mills
11:06 PM norias: a whole new world
11:07 PM robotustra: ok, gotta go sleep, working day tomorrow
11:07 PM robotustra: good night
11:07 PM norias: good lucj
11:13 PM CaptHindsight: jymmmm: yes in spades, buh dum pum
11:13 PM CaptHindsight: spade connector bus bar
11:13 PM jymmmm: CaptHindsight: I don't even need the whle thing, jst the terminal bar would do
11:14 PM jymmmm: whole*
11:15 PM CaptHindsight: jymmmm: can't you just use round or partial ring connectors?
11:15 PM CaptHindsight: drill and tap some holes in some bar you might already have
11:15 PM jymmmm: CaptHindsight: it's the QUICK disconnect I'm after
11:16 PM CaptHindsight: jymmmm: you could make one for spades using sheet and a cutoff wheel
11:16 PM CaptHindsight: or snips
11:18 PM CaptHindsight: or get some strap that fit the connectors and stack them
11:18 PM jymmmm: CaptHindsight: Eh, If I was going that route, I'd just get some uninsulated male connectors and sodler them to copper tubing
11:18 PM CaptHindsight: yeah another way
11:19 PM CaptHindsight: don't know of anything off the shelf other than what you can google
11:19 PM jymmmm: Everything I've found so far is in UK mostly
11:19 PM CaptHindsight: https://www.arc-components.com/0-005-35-pack-of-50-630mm-six-way-male-blade-terminal-block-3150.html
11:20 PM jymmmm: Yep, found those too... UK
11:20 PM jymmmm: I thought keystone made some 4 way ones, but I can't find them. Or like the ones used on HVAC caps
11:21 PM CaptHindsight: i know a guy in CHYNIA that can make millions for yah
11:21 PM jymmmm: I don't think a million is enough to fill a shipping container though
11:22 PM CaptHindsight: no worry you head
11:22 PM CaptHindsight: they pack scrap into the empty space
11:22 PM jymmmm: lol
11:25 PM CaptHindsight: you send money, we make
11:25 PM CaptHindsight: don't worry
11:25 PM CaptHindsight: whenever they say that, i worry
11:25 PM CaptHindsight: NEXT
11:27 PM jymmmm: Yep, I do too

11:52 PM roycroft: it's going to be a long time before there's a viable vaccine in quantity
11:52 PM roycroft: but there's also a lot of work being done on therapeudics
11:53 PM roycroft: if the mortality rate and the severity of symptoms can be reduced significantly with therapeudics then things can improve a lot before the vaccines are ready
11:54 PM roycroft: and i'm not talking about hydrochloroquine
11:54 PM roycroft: i'm talking about real therapeudics that actually work
