01:48 AM Deejay: moin
01:55 AM * Loetmichel is trying to crimp 1mm pitch molex/amphenol fci contacts... maaan is may eyesight getting bad... cant evev see the contacts that well, not talking about putting it in the crimper tool the correct orientation...
01:56 AM Loetmichel: whoever made that logitech PTZ2 camera should be shot on sight for using THAT connector :-(
02:21 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17835&g2_imageViewsIndex=1 <- *fiddle* ... maan i can barely see the contacs, putting them into the tool correctly is nearly impossible. :-(
02:31 AM drdoc_ is now known as drdoc
03:10 AM drdoc: morning, all
04:57 AM JT-Cave: morning
04:59 AM XXCoder: hey
06:47 AM Tom_L: morning
11:07 AM drdoc: Tom_L: you're the Mesa Man, yes?
11:08 AM drdoc: I need to spend some money. ;)
11:20 AM JT-Cave: he's a friend of the Mesa guy
11:27 AM drdoc: ah
11:27 AM drdoc: isn't everybody on this channel?
11:27 AM JT-Cave: I would hope so
11:27 AM drdoc: heh
11:28 AM drdoc: sounds like yopu'd be the Mesa guy
11:28 AM * JT-Cave notices that lunch minute is over with and heads back to the machine shop
11:28 AM JT-Cave: yup, see you out in the shop in a few
11:29 AM drdoc: okie dokie
11:35 AM JT-Shop: what do you need?
11:36 AM drdoc: basically to understand the difference between a 7i76e and a 7i96
11:36 AM drdoc: Is it just the spindle control?
11:37 AM drdoc: this will be running a pretty light-duty gantry router
11:37 AM drdoc: NEMA 23 motors, DM542 drivers
11:37 AM drdoc: 4 joints
11:40 AM burklefoo: the 7I76E has much more digital I/O, but if you don't need it, its wasted...
11:41 AM drdoc: I could also mount a 6i25, if it's a better choice
11:42 AM JT-Shop: right the 7i76e has more I/O
11:43 AM drdoc: I'm nowhere near running closed-loop anything
11:43 AM JT-Shop: I am out of stock ATM on the 7i96 cards
11:43 AM drdoc: any ETA?
11:44 AM JT-Shop: any one will work 5i25/6i25/7i92m + 7i76, 7i76e and 7i96
11:44 AM JT-Shop: I'll have to check the status of the build
11:45 AM drdoc: if I go with the 6i25, how much would I lose keeping the ChinaCo BoB instead of the 7i76?
11:46 AM drdoc: I don't want to penny-pinch myself out of functionality, but I'd like to also buy some new endmills...
11:46 AM burklefoo: The main thing you lose with cheap Chinese BOBs and Mesa cards is a fast encoder interface
11:46 AM JT-Shop: I don't know anything about that BOB
11:47 AM drdoc: JT-Shop: it's the ubiquitous Mesa 5-axis Ebay breakout board
11:48 AM drdoc: not Mesa... the other PC software
11:48 AM drdoc: brain fart
11:48 AM Thorhian: Mach?
11:48 AM drdoc: yes, thanks
11:48 AM Thorhian: Ewh, Mach.
11:48 AM drdoc: anyway
11:53 AM * JT-Shop knows nothing about Mach hardware :)
11:53 AM drdoc: uh huh
11:53 AM drdoc: :-)
11:53 AM drdoc: JT-Shop: is mesanet your storefront?
11:53 AM JT-Shop: yes
11:53 AM drdoc: ok
11:53 AM * JT-Shop wonders if he got the cam right this time lol
11:53 AM drdoc: eww
11:54 AM * drdoc hates working with cams
11:54 AM JT-Shop: lucky for me the first hole was in air and that was my clue
11:54 AM drdoc: I'm giggling
11:55 AM drdoc: I'm more of an operator monkey than machinist
11:55 AM drdoc: and more draftsman/designer than operator
11:55 AM drdoc: so that sounded real familiar
11:58 AM drdoc: If I understand what y'all are telling me, the PCIe card with a generic breakout and the 7i96 will both run the hardware I have, minus spindle control.
11:58 AM JT-Shop: looks right this time so off to cut some stock for the bp mill
11:58 AM JT-Shop: 7i96 will run a spindle
11:59 AM drdoc: ok
11:59 AM JT-Shop: pwm spindle with encoder feedback for rigid tapping etc
11:59 AM drdoc: is the 7i96 a better chouice than the 6i25?
12:00 PM burklefoo: Yeah some VFDs will take PWM input for speed control
12:01 PM drdoc: I'll be replacing my spindle next, so I can fit that to the gear I get now
12:01 PM JT-Shop: 7i96 5 axes no spindle or 4 axes and spindle
12:01 PM drdoc: ok
12:02 PM JT-Shop: I don't know what your BOB has on it, 6i25 + 7i76 is the same as 7i76e but pcie
12:02 PM drdoc: and I can add a daughterboard later to upgrade, yes?
12:02 PM JT-Shop: yep
12:02 PM drdoc: to the '96 I mean
12:03 PM burklefoo: yes, you can even add the ubiquitous 5 Axis bob to the 7I96
12:03 PM JT-Shop: smart serial can be added for more I/O
12:03 PM drdoc: OK
12:04 PM drdoc: I *really* appreciate it. I'll ask about the 7i96 availability through the store contact
12:04 PM drdoc: not sure which way I'll go, but now I understand the options a little better
12:11 PM JT-Shop: I should get an answer this afternoon
12:12 PM drdoc: ok, cool, thanks!
12:14 PM jymmmm: Loetmichel: you just need a microscope
12:16 PM jymmmm: Loetmichel: I have a perfectly working galaxy phone, except I need to install the power button, THIS power button... https://i.imgur.com/8c8oQbu.jpg
12:17 PM Loetmichel: yeah, easy
12:17 PM Loetmichel: getting the awkwardly big crump tool under the microscope though...
12:17 PM jymmmm: Loetmichel: EXACTLY, and that's why it's still sitting on the shelf waiting to be installed =)
12:18 PM Loetmichel: i Do have a microscope
12:18 PM jymmmm: Loetmichel: what about a cheap wifi microscope?
12:18 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17484&g2_imageViewsIndex=1
12:18 PM Loetmichel: even a stereo one
12:18 PM Loetmichel: but i cant get the crimp pliers under it
12:18 PM jymmmm: slide the head to hang over the edge of the bench
12:20 PM jymmmm: Loetmichel: and mount the crimpers in a vise under the microscope to hold still
12:22 PM JT-Shop: drdoc, 3-4 weeks on the 7i96
12:26 PM jymmmm: Loetmichel: Got craploads of 18650's you're not sure want to do with??? https://www.aliexpress.com/item/4001018144481.html
12:26 PM drdoc: JT-Shop: Hrrmm, ok
12:28 PM Rab: Loetmichel, many stereo scopes have an objective lens option which increases the working distance...maybe that's available for yours?
12:29 PM jymmmm: Awww, aint that cute... https://www.aliexpress.com/item/4001035369007.html
12:29 PM Rab: 'Barlow lens' I guess is the term of industry. https://en.wikipedia.org/wiki/Barlow_lens#Microscope_use
12:33 PM jymmmm: Loetmichel: Oh this looks kinda cool... https://www.aliexpress.com/item/32895132424.html
12:33 PM Loetmichel: why though?
12:35 PM jymmmm: Loetmichel: Take spae/loose 18650's and just toss em in, instant power pack
12:36 PM jymmmm: Loetmichel: I guess it's 2S3P ???
12:36 PM Loetmichel: depends
12:36 PM jymmmm: 8.4/2= 4.2
12:36 PM Loetmichel: ah
12:36 PM Loetmichel: didnt see that
12:37 PM jymmmm: I saw the 8.4v, but should have said 3.7 I 'm guessing
12:40 PM veegee: if I want to buy AC90 armoured cable for wiring my industrial unit, what's a good source in Canada?
12:41 PM veegee: there's Home Depot, but I'm not sure if they're overpriced
12:46 PM Rab: I've found Home Depot (USA) to be extremely competitive for romex and other electrical wire. Often the best price available short of wholesale. But I've never priced AC90 specifically.
12:59 PM jymmmm: Cool, an analog amp meter https://www.aliexpress.com/item/4000181169137.html
12:59 PM jymmmm: well, minus the real metal part
01:33 PM veegee: Rab thanks
01:34 PM veegee: 3m 6003 cartridges should protect against pepper spray and tear gas right? https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Organic-Vapor-Acid-Gas-Cartridge-6003-07047-AAD-60-EA-Case/?N=5002385+3294780293&rt=rud
01:34 PM veegee: With a full face mask
01:39 PM veegee: I would never go to a third world country like america and protest without something like that
01:39 PM veegee: and perhaps a leaf blower to blow the gas back at the cops
01:41 PM veegee: and maybe armour penetrating BMG 50 rounds
01:52 PM jymmmm: veegee: But, just TRY getting the filters and or mask is the hard part
01:52 PM veegee: Already have those
01:56 PM jymmmm: Oh you don't need it, just bring a airboat with you, they'll think twice about shotting off gas grenades when they feel the breeze going towrds them =)
01:58 PM jymmmm: veegee: heh heh.... https://www.bigassfans.com/fans/black-jack/
01:59 PM veegee: these protesters need to get smarter
01:59 PM veegee: need to come prepared with leaf blowers and their own pepper spray
02:00 PM jymmmm: not leaf blowers, no volume
02:01 PM jymmmm: one of those big ass fans
02:56 PM Rab: $5,900USD for the Black Jack®.
02:58 PM Rab: A friend of mine built a fan very similar to that. He used the blades from a couple of cheap ceiling fans, made a hub and shroud, and used a timing belt to run it from an e-bike BLDC motor. It sits right behind his computer monitor, pretty much spans the desk. It doesn't have to go very fast to provide a rather intimidating breeze.
02:59 PM Rab: (Texas summer, no A/C in the house.)
02:59 PM CaptHindsight: veegee: nah cutting budgets and psychological testing will get far more accomplished
03:00 PM CaptHindsight: bigassfans are at most big trade shows that cover manufacturing and warehousing
03:01 PM Rab: https://www.bigassfans.com/cow-production-stress-calculator/
03:02 PM CaptHindsight: i have a ~5ft dia. one i need to convert to BLDC
03:02 PM CaptHindsight: also works great as a white-ish noise generator
03:03 PM Rab: I have an old 7-blade box fan from Mongomery Wards. Apparently the 7-blade fans are still prized for their sleep-promoting harmonics.
03:04 PM Rab: And it's certainly more restful than modern $15 box fans.
03:05 PM CaptHindsight: the new $15 fans hardly make any noise
03:05 PM CaptHindsight: and hardly move any air
03:06 PM Rab: Similar to this one, albeit in much worse shape. Note the price: https://www.ebay.com/itm/323465630665
03:08 PM Deejay: gn8
03:08 PM Rab: I bought a nice ceiling fan with prominently-marketed computer-designed high efficiency molded plastic blades. I was outraged to find out that efficiency just translated to less airflow than the plywood paddle fan it replaced. Of course it uses less electricity!
03:10 PM CaptHindsight: bu but efficiency!! :)
03:13 PM Rab: I'm not too sympathetic with people who complain about efficiency or environmental standards, but some things really do suck now. Like a lot of fixtures & appliances.
03:16 PM Rab: But LED sure beats CFL!
03:17 PM CaptHindsight: I can't get a 2mm tap at a local store
03:17 PM CaptHindsight: they only go down to 3mm
03:17 PM CaptHindsight: need M2 x 0.40
03:18 PM CaptHindsight: ah my local MSC branch has 3 for $20ea, Mcmaster >$30
03:19 PM Rab: Grainger has several in catalog for around $20.
03:20 PM Thorhian: If you are in the US, All Industrial has metric taps.
03:20 PM Rab: I find that anything esoteric is ship-to-store here, though.
03:20 PM Thorhian: Oh wait, you want local.
03:20 PM Thorhian: RIP
03:21 PM Rab: Wow, Fastenal has a ton of M2x0.4 taps, starting around $20.
03:21 PM CaptHindsight: https://drillsandcutters.com can ship as well
03:21 PM Rab: Same caveat about store stock applies.
03:21 PM CaptHindsight: do they, i didn't even bother checking with fastenal
03:21 PM Rab: Yeah, well I usually don't.
03:22 PM Rab: Good brands, too.
03:23 PM CaptHindsight: https://www.mcmaster.com/2662A54 $17.62 Each and local for me
03:24 PM CaptHindsight: thought my cheap sets went down to 2mm
03:24 PM CaptHindsight: Thorhian: All Industrial is also local for me
03:25 PM CaptHindsight: oops sorry different one, same name
03:27 PM W1N9Zr0: local hobby store might have some, small rc cars and planes use tiny hardware (M2, 2-56)
03:27 PM Thorhian: CaptHindsight: I wish I had a local All Industrial Shop lol
03:27 PM CaptHindsight: Thorhian: allindustrial.com does not go down to M2
03:28 PM CaptHindsight: like many only M3 and up
03:29 PM Rab: W1N9Zr0, great idea. Likely not production-grade tools, however.
03:29 PM CaptHindsight: Thorhian: it really doesn't help too much since most things I need are not in stock locally or the price is higher than waiting 2 days from somewhere
03:29 PM Thorhian: That's too bad :/
03:29 PM Rab: I used to buy tiny PCB drills from the local hobby shop.
03:29 PM CaptHindsight: W1N9Zr0: I checked there as well, only M3
03:30 PM CaptHindsight: the hobby shops do carry the small drills, but so does Ace
03:42 PM CaptHindsight: hobby shop only has inch and up to 2-56
03:47 PM CaptHindsight: I need a metric hobby shop :)
03:47 PM gregcnc: there are no hobby shops left
03:48 PM CaptHindsight: just a couple good old ones around here 30+ mile drive
03:48 PM CaptHindsight: Chicago, DesPlaines
03:50 PM gregcnc: I don't know where you'd get a M2 tap around here today, but mcmaster is your best bet for tmr, a couple days just about anyone can supply
03:53 PM gregcnc: try finding fine pitch taps smaller than M8 in anything but hand
03:56 PM gregcnc: I probably have some M2 no namers if you're in a bind
04:14 PM jymmmm: mrmetric.com
04:15 PM jymmmm: no tolling shops around there?
04:15 PM jymmmm: tooling*
05:11 PM andypugh: In the UK I can get taps next-day from RS componentds. Despite being electronics they are also very handy for things like taps, nuts and bolts, tool steel, bearings and pulleys/belts.
05:11 PM andypugh: RS are always definitely next day if I order before 10pm.
05:12 PM andypugh: (yes, PM) If I can do without the next-day guarantee then Zoro.co.uk are getting a fair bit of custom.
05:12 PM andypugh: I checked and is seems that Mouser and Digikey are not so borad.
05:13 PM XXCoder: borad? broad?
05:15 PM andypugh: broad
05:15 PM andypugh: Good guess
05:15 PM XXCoder: so bored? ;)
05:15 PM andypugh: RS are just great. rswww.com
05:16 PM andypugh: Think of a thing you might want in a hurry, they probably have it. Unless you are a normal person who wants food, booze, entertainment. I
05:17 PM XXCoder: nice
05:17 PM XXCoder: andy you in uk?
05:17 PM andypugh: Yes
05:18 PM XXCoder: cool :)
05:18 PM XXCoder: ohh magnetic v block
05:18 PM XXCoder: too uncommon for me to need it to buy one lol
05:19 PM andypugh: https://uk.rs-online.com/web/p/v-blocks/6122695/
05:19 PM andypugh: Not cheap, though.
05:21 PM andypugh: Though cheaper than Zoro: https://www.zoro.co.uk/shop/hand-tools/magnets/magnetic-vee-blocks/f/4789?query=magnetic%20block
05:22 PM XXCoder: yeah. way too expensive to buy when I can just use regular ones.
05:22 PM XXCoder: now if I used ferrious metals more often at work and round ones I'd get one
05:31 PM andypugh: Machining challenge :-)
05:31 PM andypugh: https://a360.co/2z7vmjX
05:34 PM andypugh: I know that I can machine it. (but won’t give away how, because I don’t want to stifle other ideas)
05:34 PM andypugh: But what I am not sure about is how to set up to machine the tilted face in the right place in space.
05:35 PM Tom_L: odd things going on on the mill
05:35 PM Tom_L: my best guess is heat related
05:36 PM Tom_L: got a few joint following errors and one time the whole pc froze up for a bit then recovered without a reboot
05:36 PM Tom_L: been chaningint the ferror values in the axis sections of the ini
05:37 PM Tom_L: seemed to help some
05:37 PM Tom_L: siting idle i went back out to the shop to another following error while it was idle
05:38 PM Tom_L: first time i've ever had any issues with it
05:39 PM Tom_L: also a couple times it jumped position from the programmed path. luckily it was salvageable
05:42 PM XXCoder: saw clickspring do similiar. interesting
05:45 PM andypugh: XXCoder: Oh? When and where?
05:46 PM XXCoder: youtube a second
05:46 PM andypugh: The hard part is registering the new centre. If your tool is not exactly the same length as your indicator, all bets are off.
05:46 PM XXCoder: yeah clicksprings is far less precise
05:47 PM XXCoder: its making of eccentric
05:47 PM XXCoder: https://youtu.be/jaemIFvl3-0
05:47 PM andypugh: Ah. I need super-precise. The axes of the two registers need to meet at a defined point.
05:48 PM XXCoder: ouch indeed
05:49 PM andypugh: Pah! I can do that sort of eccentric in my sleep!
05:50 PM XXCoder: i cant do it awake ;)
05:50 PM andypugh: https://www.youtube.com/watch?v=FpP7iTKuWpw
05:51 PM andypugh: Then make a new hex: https://www.youtube.com/watch?v=T4q8gCpeY1A&t=3s
05:51 PM andypugh: :-)
06:16 PM skunkworks: and - another overdone spindle encoder..
06:16 PM skunkworks: andypugh:
06:16 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200604_213040.jpg
06:22 PM andypugh: I can’t help feeling that these are the answer: https://photos.app.goo.gl/5ToS8Yuk4iq77uMs8
06:22 PM andypugh: Engine timing encoder. you can press-out the hib.
06:23 PM andypugh: Magnetic track with missing-pulse index.
06:25 PM jymmmm: skunkworks: Well, when the encoder fails, you can use it as a leg wedge for a 40 ton table
06:25 PM jymmmm: to keep it from wobbling
06:26 PM skunkworks: andypugh: what res?
06:26 PM jymmmm: skunkworks: nice job btw
06:26 PM andypugh: Not _very_ cheap, but at £50 and with a very large throug-hole…
06:27 PM andypugh: I think that they are 72ppr. I can find out, but the work PC with the data is shut down,
06:27 PM andypugh: More a p-port solution
06:28 PM skunkworks: sure
06:29 PM skunkworks: jymmmm: thanks :)
06:29 PM andypugh: Actually, they are quite cheap: https://www.bestpartstore.co.uk/1890842-febi-bilstein-ring-gear-crankshaft
06:31 PM skunkworks: andypugh: do you think missing pulse index could be coded in the software encoder module?
06:32 PM andypugh: Yes, definitely. It’s on my list. And has been for 10 years.
06:34 PM jymmmm: By the time andypugh gets around to it, he'll have to reroof his parents cottage again =)
06:35 PM jymmmm: And IIRC, that only took 12 years to complete
06:35 PM andypugh: Hopefully not, we just spent £20k on having a pro do the spare hoise.
06:36 PM jymmmm: andypugh: in stone?
06:36 PM andypugh: What else can one trust to last?
06:36 PM jymmmm: hahaha, the spare house must be tiny
06:37 PM jymmmm: andypugh: or was the $20K just labor only?
06:38 PM andypugh: Re-laying the existing roof, but rebuilding the wall-tops and new purlins in the barn.
06:39 PM andypugh: Basically the stones were largerly OK, but the nails holding the laths to the rafters had gone, as had some of the wooden pegs that hold the slates to the laths.
06:40 PM jymmmm: ah, ok
06:41 PM andypugh: He under quoted, it took 2 to 5 of them from mid february to last weekend.
06:41 PM jymmmm: crane too?
06:41 PM jymmmm: Sounds liek you just got lucky =)
06:42 PM jymmmm: I think roofers would shit a brick (get it ;) if they saw a stone roof
06:42 PM jymmmm: here in the states I mean
06:44 PM andypugh: No crane. You hardly ever see a crane on a UK building site. Continental Europe can’t build a patio without a crane. It’s like a marker for “building happpening” but in the UK the builders tend to resist unless they absolutely defintely need one.
06:45 PM jymmmm: what do they use instead, block and tackle?
06:45 PM andypugh: They built a huge new lab at work, but even then they only got a mobile crane in for the day a few times.
06:48 PM SpeedEvil: jymmmm: stuff that will go through doors
06:48 PM SpeedEvil: typically.
06:50 PM andypugh: Lots of scissor lifts.
06:51 PM andypugh: Maybe it’s climate? We put the roof on as soon as possible, and from that point a crane is no help)
06:54 PM sync: andypugh: that depends, for sheet metal sheds they will also just get a mobile crane
06:54 PM sync: but for most other stuff a fixed crane is more cost effective
07:00 PM andypugh: In this case, the roof was but on by hand a few hundred years ago, so they can replace it the same way.
07:01 PM andypugh: Wish I had photos, but I can’t even visit.
07:02 PM andypugh: (I wonder if Brazil will overtake us in Death Race 2020?)
07:03 PM andypugh: It’s easy to overlook how huge Brazil is.
07:06 PM andypugh: ``About the same size as USA + Mexico: https://thetruesize.com/#?borders=1~!MTU4MTgxNDk.NzU0MjEwMg*MTUzMTE2NTk(MzU2NDA3NjE~!BR*NzU1NDQ3NQ.MTM4MTUyNDE)NA
07:06 PM andypugh: Or Canada: https://thetruesize.com/#?borders=1~!MTcxMDMzNzk.MzE2MjgxMg*MjMxNDcxMDg(Mjc4MDUzMTI~!BR*ODk3NDAzNA.MTU2MjI4NTA)NA
07:07 PM andypugh: Much bigger than Europe: https://thetruesize.com/#?borders=1~!MTYyNDQwMDI.ODc5NDk4OQ*MjQ5NzUyMTg(OTMwNDMyMA~!BR*OTEwMzY1NQ.MjE3NjYzMjg)NA
07:07 PM CaptHindsight: hardly covers any of mother Russia :p
07:07 PM andypugh: More than half…
07:08 PM andypugh: (If you drag it there)
07:26 PM unterhaus: it's funny that the true size site uses a projection that exaggerates how big europe is
07:27 PM unterhaus: that's the projection we are all used to
07:50 PM jymmmm: SpeedEvil: heh
07:51 PM jymmmm: I got my 3" to 19" scissor lift issue resolved =)
07:52 PM jymmmm: and batteyr operated to boot
07:56 PM jymmmm: Nice battery switch... https://www.amazon.com/Ampper-Battery-Disconnect-Isolator-Vehicle/dp/B07PN9CT9H
08:03 PM XXCoder: interesting
08:04 PM jymmmm: XXCoder: I thought so. the 1&2 sounds promising if if flip to the other battery to start and want to charge both.
08:04 PM jymmmm: or if it's REALLY cold and hard starting
08:05 PM XXCoder: it basically never gets that cold here
08:46 PM skunkworks: test
08:47 PM CaptHindsight: \0/
08:53 PM XXCoder: hey skunk! hows things
08:55 PM skunkworks: XXCoder: good.
08:55 PM skunkworks: keeping busy.
08:55 PM XXCoder: thats good
08:55 PM skunkworks: dad is thinking about finishing my solar collector that I started in high school
08:56 PM CaptHindsight: skunkworks: big parabola?
08:56 PM skunkworks: 112 flat mirrors
08:56 PM skunkworks: got up to 25 then got side tracked
08:56 PM Tom_L: aim it at the neighbor's window
08:57 PM CaptHindsight: but you knew it would come in handy some day
08:57 PM skunkworks: around 11kw if everything was perfect.
08:57 PM skunkworks: (if I did my math right)
08:57 PM skunkworks: wanted to use it for steam/sterling but might just be used to heat the parents house
08:58 PM skunkworks: CaptHindsight: who knew!
08:58 PM CaptHindsight: motors are cheaper now
08:59 PM skunkworks: needs some tlc - I think only 1 mirror broke that was on it - but the top pivot was held with popler logs.. long gone
09:40 PM kinch: a while ago I came across an interesting large format cutter for very light sheet material but I've lost the link. The idea was that there were two parallel rails attached to a any large table. The gantry moved itself along the rails, and the whold thing could be disassembled and the table returned to normal use. Anyone remember the name ? I keep thinking sidewinder but I can find no hits for such a cnc cutter
10:13 PM jymmmm: kinch: mechanical? cnc? manual?
10:13 PM jymmmm: what type of blade?
10:14 PM Tom_L: vinyl cutter?
10:18 PM CaptHindsight: there were a few kickstarter type plotters like that
10:20 PM jymmmm: IDK if it was vunyl he was looking for, almost sounds like a long blade mounted to a table
10:21 PM jymmmm: Tom_L: BTW,your logs aren't indexed by google it seems

10:21 PM CaptHindsight: but with a drag knife
10:21 PM Tom_L: no i told it not to
10:22 PM jymmmm: Tom_L: oh? how come?
10:22 PM Tom_L: dunno
10:22 PM Tom_L: that was a long long time ago
10:22 PM Tom_L: probably somebody bitching about it
10:22 PM CaptHindsight: Germans
10:22 PM jymmmm: Tom_L: ah, yeah I was trying to search for the link he was talking about
10:23 PM Tom_L: reprap didn't want me loggin theirs, they were afraid what they said would get back to their boss's
10:23 PM Tom_L: dumbasses
10:23 PM jymmmm: It's irc, fuck me if they cna't take a joke
10:23 PM jymmmm: em*
10:24 PM Tom_L: i didn't stay there long so i could care less now
10:24 PM CaptHindsight: don't log how much time I waste online
10:24 PM jymmmm: Tom_L: no worries
10:25 PM jymmmm: CaptHindsight: Shit, more like log when you AREN:T online, it be much m uch shorter =)
10:26 PM jymmmm: haha....
10:26 PM Tom_L: yes...

10:27 PM jymmmm: and it's acutally like add 8 years to that, because lilo messed up my account =)
10:27 PM Tom_L: i was on chatjunkies before here
10:28 PM Tom_L: since about '90ish
10:29 PM roycroft: i've only been on this network for about 10 years, but i ran a server on efnet in the mid '90s
10:29 PM roycroft: i think i started on irc there in '92
10:30 PM Tom_L: prior to that, compuserv, the source and a bunch of bbs
10:30 PM veegee: Hey guys, going to add some hard air lines to the shop
10:30 PM Tom_L: hooray!
10:30 PM veegee: What tube should I use? Copper pipe ok?
10:30 PM Tom_L: what pressure?
10:30 PM veegee: Less than 200 psi
10:30 PM roycroft: pvc should be fine for low pressure like that
10:30 PM Tom_L: if you do get the thickwall stuff
10:31 PM roycroft: or black pipe
10:31 PM veegee: PVC = great pipe bomb material
10:31 PM Tom_L: i used black pipe on mine
10:31 PM roycroft: if you like doing things the old fashioned way
10:31 PM veegee: black pipe is an option but I'll have to add an air dryer, which I have
10:31 PM roycroft: my shop air lines are black pipe
10:31 PM Tom_L: it's not only will it hold the pressure but what can i run into it with
10:31 PM veegee: Tom_L what do you mean by that?
10:31 PM veegee: You intend to run into it with your car?
10:32 PM Tom_L: hell for all i know you drink n drive your forklift :)
10:32 PM veegee: I do
10:32 PM veegee: but I have two perfect alleles for the alcohol dehydrogenase enzyme and a perfectly functioning elimination pathway
10:32 PM Tom_L: guy poked a hole in the celing mounted 3 phase lines with a forklift once at a place i worked
10:33 PM veegee: But I'm a bit worried about the black pipe rusting
10:33 PM veegee: And no way in hell am I going to use PVC for any compressed gas
10:33 PM Tom_L: i just didn't wanna leave out black pipe is all
10:33 PM roycroft: use galvanized pipe then
10:34 PM roycroft: it costs a little more but it won't rust
10:34 PM Tom_L: i used to have a dryer on mine
10:34 PM veegee: ah ok guess I'll go with that
10:34 PM roycroft: buy lots of unions
10:34 PM Tom_L: copper would be fine and easier
10:34 PM roycroft: it will make the job a lot easier
10:34 PM veegee: How are they joined? Are they welded or threaded?
10:35 PM Tom_L: i'd add drops like they do gas lines if you do
10:35 PM veegee: But yeah I'm leaning towards copper
10:35 PM veegee: and adding drops yes
10:35 PM Tom_L: and ballvalves on em
10:35 PM veegee: of course
10:36 PM veegee: All this would work nicely with copper pipes
10:36 PM Tom_L: i gotta unplug the ballvalve drain on my tank soon
10:36 PM Tom_L: it's plugged up
10:36 PM veegee: copper pipe has a higher pressure rating than I'll ever need so I guess that works
10:37 PM roycroft: copper is expensive
10:37 PM Tom_L: he don't care. he just bought a forklift for a hobby....
10:37 PM jymmmm: PEX is rated at 160 PSI
10:37 PM veegee: True, but it's not something I'm going to leave in the building when we move out
10:37 PM roycroft: i would not use pex
10:37 PM veegee: yeah definitely not PEX
10:38 PM jymmmm: why not? you the Gas rated, thicker
10:38 PM roycroft: my compressor is set to 130psi
10:38 PM roycroft: that's too close to 160psi for me
10:38 PM roycroft: plus, plex is too easy to damage
10:38 PM Tom_L: mine shuts off at 170psi
10:38 PM veegee: I have my compressor cut out at 175 psi
10:38 PM jymmmm: and easy to repair/replace, and cheap
10:38 PM Tom_L: or that
10:38 PM Tom_L: never paid that close attention to it
10:39 PM Tom_L: get a tankless screw compressor
10:39 PM jymmmm: gas pex is less, only 125psi
10:40 PM veegee: I considered a screw compressor, but I don't like that they're low pressure
10:40 PM veegee: I like high pressure/high voltage
10:40 PM Tom_L: not that low
10:40 PM Tom_L: at least not the one my bud had
10:40 PM veegee: My pump is rated up to 300 psi
10:40 PM Tom_L: he had it in a room all by itself
10:40 PM Tom_L: it was kinda noisy
10:41 PM jymmmm: Fine, get a SS billet and chuck in on the lathe, make your own 2" thick walled pipe =)
10:41 PM Tom_L: oil drill pipe
10:41 PM veegee: there's a very big difference between shitty pex and copper/black pipe
10:42 PM Tom_L: AC use copper and they're 300psi or more
10:42 PM veegee: Yeah
10:42 PM jymmmm: Just get the cheapest garden hose from harbor freight, you'll be fine... "Trust me" =)
10:44 PM jymmmm: Today's top story "Man gets decapitated from garden hose"
10:44 PM veegee: Contemplating buying this lathe: https://www.kijiji.ca/v-view-details.html?adId=1503881855
10:44 PM veegee: Still looking, but that's an option
10:45 PM jymmmm: I wish grey plastic conduit had a pressure rating, that does doens't crack/shatter like PVC pipe does
10:46 PM Tom_L: veegee, any tooling?
10:46 PM Tom_L: that's more than half the cost
10:46 PM veegee: Yeah, I'm going to ask him about that
10:47 PM roycroft: pvc can be perfectly safe for 200psi air if it's protected from physical damage
10:47 PM Tom_L: is that a foot brake or just a rest?
10:47 PM roycroft: but it can fail spectacularly if you smash it
10:47 PM jymmmm: roycroft: I've seen 150psi rating, but not 200 psi
10:47 PM Tom_L: a foot brake is nice to have on a manual lathe
10:48 PM veegee: hmm good question
10:48 PM veegee: the fact that it's mounted to a round tube suggests it's a lever
10:48 PM veegee: so possibly a brake
10:48 PM veegee: That would be a really weird way to make a foot rest
10:49 PM jymmmm: veegee: Ok just need to use SCH80 not common SCH40... https://www.aetnaplastics.com/site_media/media/attachments/aetna_product_aetnaproduct/204/PVC%20Sch%2080%20Pipe%20Dimensions.pdf
10:49 PM CaptHindsight: veegee: I run hoses around
10:50 PM CaptHindsight: https://pvcpipesupplies.com/cpvc-vs-pvc
10:52 PM veegee: CaptHindsight hmm CPVC looks interesting. I'd rather have something ductile than brittle
10:53 PM veegee: But yeah rigid plastic pipe makes me uncomfortable
10:53 PM veegee: I know people do it
