12:43 AM Deejay: moin
01:41 AM CaptHindsight: laugh now but in a hundred years you'll be missing water
01:41 AM CaptHindsight: since it will have evaporated out of you
02:30 AM roycroft: not if sea level keeps rising
02:30 AM roycroft: you'll be under water in a hundred years
02:31 AM XXCoder: man
02:31 AM XXCoder: you guys must have found out secrets to immortality
02:32 AM XXCoder: because in pretty lot less than 100 years, i'll be dead
02:32 AM roycroft: ok, it's time to let the cat out of the bag
02:32 AM XXCoder: good, it needed some oxygen
02:32 AM roycroft: the truth is, xxcoder, covid-19 really *IS* a hoax
02:32 AM roycroft: there is no such thing
02:33 AM roycroft: but the vaccine is actually an immortality serum
02:33 AM roycroft: so all democrats are now immortal, because they are vaccinated
02:33 AM roycroft: and all republicans are gonna die
02:33 AM XXCoder: lol
02:33 AM XXCoder: thats good i guess
02:35 AM XXCoder: about immortality https://www.smbc-comics.com/comics/20110315.gif
03:04 AM drdoc: roycroft: I am now
03:06 AM drdoc: what's wrong with this picture? Find the Waldo:
03:06 AM drdoc: https://smile.amazon.com/dp/B017LG2FUS
05:39 AM drdoc: hola
05:41 AM drdoc: Huh.
05:42 AM drdoc: The dev options in this CAT phone allow unlocking the bootloader
06:31 AM JT-Cave: morning
07:27 AM Tom_L: JT-Cave, get anywhere with your part?
07:33 AM JT-Cave: I was out most of the day
07:38 AM Tom_L: you know what size cutter you're gonna use i can get you a perimeter
07:43 AM Tom_L: mm looks like a chance of rain later on hi 76F
07:48 AM drdoc: we're on our 3rd day of "gonna storm real soon now"
08:13 AM JT-Cave: Just trying to load the part in onecnc to see if it will generate the perimeter, prob use a 1/2" end mill
08:28 AM skunkworks: Cat phone?
08:39 AM JT-Shop: Tom_L I think I have a cut path in onecnc
08:46 AM JT-Cave: I need to get a slab of gold to practice on, I think it's cheaper than wood
08:51 AM JT-Cave: raw lumber prices keep falling and osb keeps going up Lowes $66.50, Menards $54.28, Home Depot $64.75
08:51 AM JT-Cave: opps Menards is $60.99
08:57 AM pcw_home: Apparently there is a beer can shortage also...
09:29 AM drdoc: pcw_home: the local supermarket chain has been short-stocking store-brand sodas for months and blaming the can shortage
09:29 AM drdoc: JT-Cave: I've been playing with foamed PVC for test runs
10:00 AM Tom_L: JT-Cave, what do they get for onecnc, that doesn't look too bad
10:04 AM perry_j1987: morning
11:22 AM JT-Shop: Tom_L, not sure what it goes for now, I bought around 2004 and upgraded once or twice
11:23 AM Tom_L: which package did you get?
11:23 AM Tom_L: 2.5d or full 3d?
11:24 AM JT-Shop: x4 mill 3d pro
11:25 AM Tom_L: 4 axis?
11:25 AM Tom_L: how do they charge for annual / update fees?
11:25 AM JT-Shop: 3
11:25 AM Tom_L: some of the big ones charge annually
11:26 AM JT-Shop: IIRC only if you upgrade to the next version
11:26 AM JT-Shop: you have to have the dongle plugged in to use it
11:26 AM Tom_L: from what i can see from their site it looks pretty decent but a hands on would tell alot more
11:26 AM Tom_L: yeah mine had a dongle too but i got tired of it so i found a way around it
11:27 AM Tom_L: mine was parport, i suppose most are usb nowdays
11:27 AM JT-Shop: I can say for sure onecnc is better than bobcrap
11:27 AM Tom_L: well yeah, bob used to be free
11:28 AM JT-Shop: I've not used any of the higher end cam programs
11:28 AM Tom_L: they're all about the same but some have better / easier features
11:28 AM JT-Shop: I upgraded bc when I bought the bc mill and what a mistake that was
11:29 AM Tom_L: well, if you have trouble with the part, i've got a path but didn't know what cutter you were gonna use
11:29 AM * JT-Shop thinks shortly there will be a napping operation going on
11:29 AM Tom_L: and if you wanted to follow the curve or just use a flat pattern of it
11:30 AM Tom_L: that's not much of a lip around the part... ~.060" on the flat
11:30 AM JT-Shop: I made a path of the top of the flange but it's engrave so I'll have to use a 1/4" em
11:31 AM Tom_itx: i can cut the step for the lip for a pocket cutout as well
11:32 AM Tom_itx: damn interweb
11:32 AM Tom_itx: i used the outer edge surface of the flange
11:35 AM Tom_itx is now known as Tom_L
11:40 AM JT-Shop: looks like I might have a tool path for the lip and the pocket
11:40 AM Tom_L: i dunno why it wouldn't let me export the parts i extracted
11:40 AM Tom_L: they were still surfaces
11:40 AM Tom_L: once i explode them into polylines, it won't export
11:40 AM JT-Shop: nap time here now that I've cooled down from stacking firewood
11:42 AM drdoc: I've never run a variable-speed motor that didn't have a jiggly speed
11:43 AM roycroft: only time will tell if it's as reliable as something like a baldor, but if it lasts 1/4 a long as a baldor it's a good value
11:43 AM roycroft: i'm not concerned about it, but i may be able to smooth it out a bit with some fine tuning of the vfd
11:44 AM drdoc: good chance that putting a belt on will damp it some
11:45 AM drdoc: spec sheet claims it's good to 5400rpm, right?
11:45 AM roycroft: i'm running it with a belt on
11:45 AM roycroft: i said "under load" above
11:45 AM drdoc: ah
11:45 AM roycroft: and the vibration is not bad
11:45 AM drdoc: I haven't been to bed yet
11:45 AM roycroft: in fact, i did not notice it at first - i heard it
11:46 AM roycroft: and then i put my hand on the motor and could feel it
11:46 AM roycroft: no worries
11:46 AM drdoc: something like that, sometimes I'm not sure whether I feel it or hear it
11:48 AM roycroft: i'm not worried about the vibration
11:48 AM drdoc: right
11:48 AM roycroft: my only concern is that it stalls at a higher speed than i'd like, and torque drops off quite a bit as it approaches the stall speed
11:48 AM roycroft: i'd like to be able to run it at around 1750rpm with good torque
11:48 AM roycroft: and i can probably tune the vfd to get better low speed performance
11:49 AM drdoc: it stalls at a higher speed than you want?
11:49 AM roycroft: it stalls at about 1400rpm
11:50 AM roycroft: and the torque curve drops off rapidly below ~2400rpm
11:50 AM drdoc: huh
11:50 AM drdoc: the specs claim something like 850?
11:51 AM roycroft: yes
11:51 AM drdoc: that ain't good
11:51 AM roycroft: but the vfd can probably improve that
11:52 AM drdoc: right
11:52 AM roycroft: and yes, it is rated at 5400rpm
11:52 AM roycroft: but it's from china
11:52 AM roycroft: 4200rpm is probably fine :)
11:52 AM roycroft: that's as fast as i'd ever need anyway
11:52 AM drdoc: JT-Shop: It might help if I post the link....
11:52 AM drdoc: https://www.ebay.com/itm/133668666922
11:52 AM roycroft: although i did find that i have a 4" drive wheel with a 5/8" shaft
11:52 AM roycroft: the one i'm using is 5"
11:53 AM roycroft: i could have just used the 4" without needing a bushing, and run the motor faster
11:53 AM drdoc: trade some rpm for lb/ft?
11:53 AM drdoc: errr
11:53 AM drdoc: trade some sfm for lb/ft?
11:53 AM roycroft: i need to figure out how to trick the vfd into displaying sfm instead of rpm
11:54 AM drdoc: want a cheap AVR-based DRO?
11:54 AM drdoc: ;-)
11:54 AM roycroft: no
11:55 AM roycroft: i'm pretty sure i can do it with the vfd
11:55 AM drdoc: are Delta VFD any good?
11:56 AM roycroft: i don't know
11:58 AM drdoc: I don't think I'm going to try to upgrade the Baldor motor
11:59 AM drdoc: I can convert it to 3 or 5 speed belt drive easily and cheaply using that motor
12:00 PM drdoc: if I want to go further than that I'll just build it
12:03 PM roycroft: i've found that being able to reverse the motor is very useful when using my grinder horizontally
12:03 PM roycroft: just because when it's horizontal it's better for me to shoot the dust to the left than to the right
12:04 PM roycroft: while i haven't needed the variable speed function much, i do use the reverse function all the time
12:04 PM roycroft: i'll be running it slower a lot more often now, though, than i used to
12:08 PM drdoc: roycroft: I kind of want to run this:
12:08 PM drdoc: https://www.ebay.com/itm/153735777071
12:21 PM Rab: drdoc, looks powerful and economical. My advice, Buy It Now.
12:21 PM drdoc: lol
12:21 PM drdoc: I am seriously considering a copy of Camsoft AS3000
12:21 PM Rab: Then you will only need a Quadra 700 with matching color monitor. Please, won't you take my Quadra 700 with matching color monitor?
12:21 PM drdoc: I will!
12:22 PM drdoc: you have one?
12:22 PM Rab: Of course!
12:22 PM drdoc: you really want it gone?
12:22 PM drdoc: cuz mine is one of those "cold dead fingers" items
12:23 PM Rab: ...Now my internal hoarder is getting cold feet. ;)
12:23 PM drdoc: lol
12:24 PM Rab: I also have an SE/30, but it's probably less well suited to run the Douglas CAD/CAM Professional Software System.
12:24 PM drdoc: right?
12:25 PM drdoc: if you do want to divorce the quadra, I'm interested
12:25 PM Rab: OK, cool!
12:26 PM drdoc: I might have some tidbits for the SE/30, too
12:26 PM drdoc: I know I have a working copy of EZ-CD for 68k
12:26 PM Rab: I have a little bit of data that I'd like to get off of it. But that involves powering it on, which is very risky these days. But there is no way I will ever recap or do any restoration.
12:26 PM drdoc: :-)
12:27 PM drdoc: the q700 or the SE/30?
12:27 PM Rab: Q700]
12:27 PM drdoc: oh
12:27 PM Rab: Actually, I think the same stuff is on the SE/30 external SCSI drive.
12:28 PM drdoc: well, I have a working mac if you need a disk dump
12:29 PM Rab: Sounds good, you want them both?
12:31 PM roycroft: i really need to do something about this imac
12:31 PM roycroft: it's a nice machine, generally, but it has one of those confounded "fusion" drives, and to say it's painfully slow is an insult to all pain everywhere
12:32 PM roycroft: i'm thinking it may be time to get an external thunderbolt drive enclosure, and a 2TB ssd, and to boot off the ssd
12:33 PM drdoc: lol
12:33 PM drdoc: this is why my mac is an Asus z370...
12:34 PM drdoc: it's pretty dadblame zoomy
12:35 PM Tom_L: vroom vroom
12:37 PM drdoc: AS3000
12:37 PM drdoc: Camsoft - are they any good?
12:57 PM JT-Shop: drdoc, aye but that one is 3 generations newer than mine and they don't say if it's expert or pro... makes a big difference
12:57 PM * JT-Shop goes back to sitting with the chickens
01:05 PM drdoc: why do people hate on BobCAD so often?
01:07 PM drdoc: I mean I see a lot of dissatisfied users of mretty-much any cad/cam software, but no other package draws that kind of unremitting ire.
01:07 PM Tom_L: there's a big difference between hobby and pro level cad cam
01:07 PM drdoc: yes
01:07 PM Eric__: people hate bobcam because they would aggressively call you to give them more money
01:08 PM Eric__: I don't know if they have reformed their ways or not
01:08 PM drdoc: Eric__: that'll do 'er
01:08 PM Eric__: I have seen complaints about the software, but for the price it seems okay to me
01:09 PM skunkworks: pcw_home: could you move the 4th step gen to p1 p32/33? get rid of one of the smart serial interface that is there
01:09 PM drdoc: I'm really kind of leaning toward SheetCAM, simply because I know somebody who uses it and have seen his work
01:09 PM skunkworks: https://pastebin.com/CACCz3rU
01:09 PM Tom_L: dam sam, all these personal requests...
01:09 PM skunkworks: Tom_L: right!? I suprised he hasn't told me to make them myself..
01:10 PM Tom_L: hah
01:10 PM Tom_L: it's not too difficult
01:10 PM skunkworks: I know you have..
01:10 PM Tom_L: i haven't done one in quite a while. i'd be a little rusty
01:10 PM drdoc: I tried the Mecsoft demo, MeshCAM, and that level of simplification smells like busted tools to me
01:11 PM skunkworks: It will allow me to run the 4th axis on the green machine.
01:11 PM Tom_L: :)
01:11 PM skunkworks: Tom_L: did you see andy's video?
01:12 PM Tom_L: what vhd file?
01:12 PM Tom_L: no i must have missed that
01:12 PM drdoc: Tom_L: I'm looking for decent, cheapish hobby level 2D or 2.5D CAM
01:12 PM Tom_L: you and everybody else
01:12 PM Tom_L: 2.5 d is pretty easy to find
01:12 PM drdoc: it'd be nice if it imported STEP or iges insted of STL & DFX
01:13 PM Tom_L: well then you get into 3d
01:13 PM Tom_L: dfx etc are flat files
01:13 PM Tom_L: iges step are not
01:13 PM drdoc: yes
01:13 PM skunkworks: https://www.youtube.com/watch?v=otycJD_0478
01:13 PM skunkworks: Tom_L: vhd?
01:14 PM drdoc: but a lot of the cheap 2.5D does STL, which is pretty awful
01:14 PM Tom_L: the source file
01:14 PM Tom_L: see i even forgot what they were now :D
01:14 PM skunkworks: pcw_home: no rush
01:15 PM skunkworks: heh - I don't know
01:15 PM Tom_L: you don't know what file you load?
01:15 PM Tom_L: i bet it's called skunkworks.vhd
01:16 PM skunkworks: this is a 7i92 - so you don't load the firmware.
01:16 PM drdoc: I guess spending ~$400 on a transferrable dongle doesn't suck
01:16 PM skunkworks: I write the bitfile to it..
01:17 PM skunkworks: (unlike the 5i20 or such)
01:17 PM CaptHindsight: drdoc: have you tried the CAM in FreeCAD?
01:17 PM skunkworks: Tom_L: but you are probably right - the bit file was probably called that.. ;)
01:17 PM drdoc: I haven't even tried FreeCAD
01:18 PM drdoc: not in a while
01:18 PM CaptHindsight: it's evolving
01:18 PM CaptHindsight: active development
01:18 PM drdoc: will it import straight to cam or do I have to design from scratch on the CAD side?
01:19 PM CaptHindsight: skunkworks: I like how it sounds like a steam engine and has puffs of smoke
01:20 PM skunkworks: CaptHindsight: about what?
01:20 PM CaptHindsight: drdoc: it can import a few formats
01:21 PM CaptHindsight: skunkworks: Andy's video, early on when he starts to cut :)
01:21 PM drdoc: CaptHindsight: I realized recently that if I had worked with KiCAD more when it was a useless POS I'd be great with it now, instead of totally lost
01:21 PM JT-Shop: drdoc, have you used bobcrap?
01:21 PM CaptHindsight: https://youtu.be/otycJD_0478?t=209
01:21 PM drdoc: I have not
01:22 PM JT-Shop: OK you won't understand... I've used it when I got my first cnc mill
01:22 PM JT-Shop: it's really terrible
01:22 PM drdoc: JT-Shop: I've used mastercam, mostly, failed a lot at topsolid, EstlCAM and flatcam
01:22 PM skunkworks: CaptHindsight: ah! yes
01:23 PM JT-Shop: I've not even heard of the last 3
01:23 PM drdoc: TopSolid is supposed to be the giant-killer
01:23 PM JT-Shop: linux or windblows?
01:23 PM drdoc: and it's probably great if you read French
01:23 PM drdoc: Windows
01:24 PM JT-Shop: french and windows what a killer
01:24 PM drdoc: stupid expensive
01:24 PM drdoc: yeah
01:24 PM drdoc: EstlCAM is strictly 2D and not keeping up with the opensource competition
01:24 PM * JT-Shop wanders back outside to watch the chickens, they are in a lightly protected area feasting on greens
01:25 PM drdoc: flatcam is strictly PCB
01:26 PM sinned6915: skunkworks: are you ears burning?
01:27 PM CaptHindsight: skunkworks: how is the harmonic drive testing out, been following on the ML
01:28 PM Tom_L: drdoc, nothing imports straight to cam :)
01:28 PM Tom_L: nice idea though
01:28 PM drdoc: heh
01:28 PM CaptHindsight: skunkworks: have you run it long enough for it to fail?
01:28 PM drdoc: they all tell you they do though
01:28 PM Tom_L: you generally have to clean the part up, orient it, fixture it etc
01:29 PM drdoc: I know
01:29 PM Tom_L: i can tell you i have some beach front property in Arizona i'd love to sell you too
01:29 PM skunkworks: CaptHindsight: no. Not the petg version.. SO far. But I haven't been working on it much
01:30 PM drdoc: the aggravating part, for me, is that I've done all this in fab since, ohhh, 1973 or so
01:30 PM drdoc: where CAD was "chalk aided design
01:30 PM drdoc: "
01:30 PM pcw_home: skunkworks: what is your current bitfile name?
01:31 PM Tom_L: haha
01:31 PM Tom_L: sry, we were teasing him it's probably skunkworks.vhd
01:31 PM pcw_home: (if I was smart I would have included in the the IDROM)
01:32 PM drdoc: it's not that I expect those skills to carry over, but that the beachfront property aspect is so heavy
01:32 PM drdoc: I'm stealing that line, at 07:40
01:33 PM drdoc: "Luckily I have low standards and am easily satisfied."
01:33 PM skunkworks: pcw_home: let me see if I can find it
01:34 PM drdoc: Tom_L: I guess I really just want somebody to point at a [software] hammer and tell me "leanr that one and get back to me
01:34 PM drdoc: "
01:35 PM skunkworks: pcw_home: I think it was 7i92_mx3660_ssed.bit
01:37 PM veegee: I'm so glad this site exists: https://accusizetools.com/collections/indexable-turning-tools?sort_by=price-ascending
01:37 PM veegee: Good price/quality ratio and local
01:38 PM veegee: Arrives at my door next day for < $10 shipping
01:40 PM veegee: What do you think the air pressure in an air mattress is?
01:40 PM CaptHindsight: veegee: not much
01:40 PM veegee: I'm guessing just a few pascals above atmospheric. Don't have a gauge that measures that low.
01:41 PM veegee: My air mattress is leaking very slowly but an easy fix is a bulkhead fitting hooked up to my air compressor line
01:41 PM CaptHindsight: veegee: we used to have a place called Enco
01:41 PM Tom_L: drdoc, well then if that's all you want.. go get a full seat of catia and learn it and get back to me.
01:41 PM drdoc: did we say "hobby grade"?
01:41 PM CaptHindsight: but they were bought out and the prices jumped
01:41 PM drdoc: Why yes! Yes we did!
01:41 PM Tom_L: oh
01:42 PM drdoc: :-)
01:42 PM veegee: PM me if you want licences ;)
01:42 PM Tom_L: that onecad jt mentioned looked nice
01:42 PM veegee: JT-Shop can I feast on your chickens?
01:42 PM drdoc: it does, and not awfully expensive
01:42 PM Tom_L: it can be, just depending on what you get
01:42 PM drdoc: that AS3000 on Ebay looks very nice
01:44 PM drdoc: but their sub on cnczone has 5 posts in 2 years
01:45 PM drdoc: I'm tempted anyway, at ~$400
01:51 PM Tom_L: if i had to google it, i'm not interested
01:54 PM drdoc: right?
01:54 PM drdoc: I think heeks and/or Freecad are as good a starting place as any
01:55 PM Tom_L: freecad is getting better but i'm not sure it's there yet
01:55 PM Tom_L: for a commercial product i think fusion 360 is way lacking but alot of ppl use it
01:56 PM drdoc: I'd rather support FreeCAD's flaws than F360
01:58 PM drdoc: like I said earlier, I wish I'd learned to work around KiCAD's failings when it just barely worked
01:59 PM drdoc: but I have access to a full Eagle seat, so why bother
01:59 PM drdoc: now KiCAD is getting better, fast, and Eagle... isn't
01:59 PM Tom_L: i've got a 16? layer seat to that too but it's old
02:00 PM roycroft: freecad needs to decide on an assembly workbench and stick with it
02:00 PM Tom_L: roycroft, no they're gathering feedback and in a few years they'll settle on one
02:00 PM drdoc: assemblies is what made me throw rocks at Fusion
02:01 PM roycroft: they've been gathering feedback on assembly workbenches since about 2003
02:01 PM drdoc: have any of y'all worked with Heeks?
02:01 PM veegee: drdoc "I'd rather support FreeCAD's flaws than F360"; as much as I love open source, I don't have time to waste for FreeCAD's major flaws
02:01 PM veegee: I would really like to overhaul it though. I wish I had the time
02:01 PM drdoc: the thing is, that FreeCAD *will* improve.
02:02 PM roycroft: i feel embarrassed for the freecad developers that they have let this go on for so long and have chosen to deal with it by pretending it's not important
02:02 PM veegee: They should just copy Fusion360 and be done with it
02:02 PM drdoc: Fusion360 has every incentive not to
02:03 PM roycroft: anyone who for even a moment thought that autodesk would not eventually tighten the screws on fusion360 is a fool
02:04 PM drdoc: ^^^^^^^^
02:04 PM roycroft: and anyone who thinks they're done with the screw tightening is also a fool
02:04 PM drdoc: ^^^^^^^^
02:05 PM roycroft: the history of fusion360 for makers is flip-flopping between "gee this is really nice - autodesk are great folks" and "what they hell!? they just took this away from me! what jerks!"
02:06 PM * Tom_L snickers
02:11 PM Tom_L: andypugh, nice video on the chuck adapter
02:12 PM pcw_home: skunkworks: http://freeby.mesanet.com/7i92_sw.zip
02:12 PM Tom_L: damn. same day delivery. better than any mail service!
02:13 PM pcw_home: I moved stepgens 3 and 4 around so 'A' is 3 and the chargepump stepgen is 4
02:15 PM pcw_home: Tom_L This is theoretically "work", otherwise I need to go outside and weed-whack our front yard
02:15 PM Tom_L: yeah i'd be sitting behind the screen too then :)
02:16 PM Tom_L: my excuse is it's still to wet to mow
02:18 PM pcw_home: Dry as a bone here (no significant rain since March) so that's a no-op
02:21 PM roycroft: it's pretty dry here now as well
02:21 PM roycroft: we finally got up to normal snowpack last winter, but now it's all dried up
02:23 PM roycroft: i fear fire we're soon going to end up like california, with fire season starting the beginning of february and ending the end of january
02:23 PM roycroft: s/fear fire/fear/
02:23 PM roycroft: bad editing there :)
02:24 PM pcw_home: Yeah we had enough snowpack that we are not short of water but this is going to be a really bad fire season
02:24 PM skunkworks: pc pcOAOA
02:24 PM skunkworks: OAOA`.
02:25 PM skunkworks: heh
02:25 PM skunkworks: pcw_home: it looks perfect! thank you!
02:27 PM pcw_home: Yeah check the pinout I could not find the original source but found one with just one encoder
02:27 PM skunkworks: pcw_home: it even lauched and homed! :)
02:27 PM skunkworks: Now for some more wiring...
02:28 PM pcw_home: better than most of my first trys...
02:29 PM skunkworks: (which meams the smart serial and everything worked..)
02:29 PM Tom_L: yay
03:21 PM andypugh: Thanks Tom_L . XXCoder might like to know that I uploaded the an actual transcript of my voiceover. Typos and all.
04:14 PM Tom_L: andypugh, i have no audio on this pc anyway so i missed half of it i guess
05:01 PM XXCoder: andypugh: yeah already watched with captioms. it was nice
06:11 PM Tom_L: andypugh, did you keep track of the hours it took to machine one?
06:12 PM andypugh: No, but as the video itself is an hour long, I am not sure I want to know.
06:12 PM Tom_L: heh
06:13 PM Tom_L: editing alone took a few min
06:14 PM XXCoder: lol
06:14 PM XXCoder: well it was really enjoyable video
06:15 PM Tom_L: andypugh, what exactly is silver rod
06:17 PM andypugh: It’s what you call drill-rod, I think.
06:18 PM Tom_L: ahh ok
06:18 PM andypugh: Centreless groind tool steel.
06:18 PM Tom_L: we have both oil and water quenched
06:18 PM andypugh: Accurately sized, hardens well. Very widely available.
06:18 PM Tom_L: oil being the higher quality of the 2
06:19 PM Tom_L: yeah i know what it is, just not what you called it :)
06:20 PM andypugh: Well, the “very widely available” part was, I thought, worth mentioning.
06:21 PM andypugh: In fact I used to be able to walk to a local shop and buy it on a saturday morning. But they had a flood and rather than re-fit that branch was consolidated with another rather too far away.
06:22 PM CaptHindsight: you Brits have such a difficult language to grasp
06:22 PM Tom_L: my local guy that has it is within walking distance but he's getting pretty old and i dunno how long that resource will be there
06:23 PM XXCoder: no intern and such?
06:23 PM Tom_L: i dunno if anybody will take it over
06:24 PM Tom_L: his dad started it and this guy has to be in his late 80's
06:24 PM XXCoder: :( sad when such skills disappear
06:43 PM roycroft: so i found a problem with my new motor - the cable knockouts on the wiring box are not really knockouts - they're faint impressions on the metal
06:43 PM roycroft: i had to use a chassis punch to make the hole
06:43 PM roycroft: not a major problem, but some folks may not have chassis punches or hole saws or other means to make holes like that
07:34 PM drdoc: andypugh: is XXCoder deaf too?
07:34 PM XXCoder: why not ask me directly?
07:34 PM drdoc: XXCoder: is andypugh deaf too?
07:35 PM drdoc: :-P
07:35 PM XXCoder: lol
07:35 PM XXCoder: andy no idea though not very likely
07:36 PM drdoc: Tom_L: drill rod being W1 or W2?
07:36 PM drdoc: XXCoder: are *you* deaf too?
07:36 PM drdoc: <-- like a stump
07:36 PM XXCoder: i am deaf yes.
07:37 PM drdoc: there are a few niches in which youtube is the very best choice for documentation
07:37 PM drdoc: a VERY few
07:38 PM drdoc: I'll leave my standard rant under the soapbox this time
07:39 PM XXCoder: lol ok
07:39 PM drdoc: XXCoder: I had an AutoCAD prof who was required, by contract, by the school, to disable closed captions in her YT lecture videos
07:39 PM XXCoder: wha
07:40 PM drdoc: nobody has ever explained it, but somehow YT's autogenned captions turn everything she says into pure filth
07:40 PM drdoc: it's amazing. Like miraculously consistent
07:40 PM XXCoder: how old is that? there used to be user submitted captions
07:40 PM XXCoder: youtube removed that due to abuse and adverts in captions
07:41 PM drdoc: 5 years or so?
07:41 PM XXCoder: yep its possible that someone keeps uploadinbg crap
07:42 PM drdoc: no, it was bad enough that YT got in on it
07:42 PM drdoc: and it takes a bit of time for someone to corrupt an entire lecture
07:42 PM drdoc: the youtube techs were pretty sure it was a bug
07:43 PM XXCoder: wow thats weird
07:43 PM XXCoder: but that contract is shit
07:43 PM drdoc: well, it's not like she minded
07:43 PM XXCoder: should make it either require no caption OR properly worded captions submitted by her
07:44 PM drdoc: they didn't want to pay her OT for transcription
07:44 PM drdoc: community college, contract prof, etc etc etc
07:45 PM drdoc: that girl was a lot of fun though
07:45 PM XXCoder: too bad for deaf people wanting to watch video then
07:45 PM drdoc: in class, I mean
07:45 PM drdoc: yes
07:45 PM drdoc: XXCoder: I've never understood why people blame me for being deaf
07:46 PM drdoc: but they do
07:46 PM XXCoder: its basically from extremely antique view that person born with problems is due to previous life being awful and whatever
07:47 PM XXCoder: or otherwise at fault "because olviously"
07:47 PM drdoc: but that rarely happens to people who are blind or otherwise disabled
07:48 PM drdoc: very young adults, especially, seem to believe that I could hear them if I wanted to
07:48 PM XXCoder: galliet motto: "teaching deaf how to hear"
07:48 PM drdoc: lol, yes
07:48 PM XXCoder: good luck with that. im rare example of 100% deaf
07:48 PM drdoc: ah
07:48 PM drdoc: 80%
07:49 PM XXCoder: nearly all deaf have tiny residental hearing like 97% for my brother
07:49 PM drdoc: well, in my good ear
07:49 PM drdoc: yes
07:49 PM drdoc: in a classic example of gunners' ear, I can still hear a bearing knock at a hundred yards
07:50 PM XXCoder: whats gunner ear?
07:50 PM drdoc: hearing damage due to very loud, sharp noises
07:52 PM drdoc: typically less than 30% loss up to 1.5-2khz and then there's a cliff in the graph
07:52 PM XXCoder: interesting
07:52 PM XXCoder: my hearing graph is rather boring
07:53 PM drdoc: yes, it would be
07:53 PM drdoc: in other words, I hear just fine if it's a bunch of old men and there's no ambient noise
07:53 PM XXCoder: LOL in other place i just read this: "In the vein of "incompetent thieves": Someone attempted to rob the factory I work at several months back and totalled a brand new truck they were renting by carrying vastly more weight than it could handle for 50 some miles. The truck itself was worth more than the metal they were trying to steal, and by a large margin"
07:54 PM drdoc: good job, bubba!
07:54 PM XXCoder: earlier someone said he used a shotgun to scare off thief trying to steal clystic off car
07:54 PM XXCoder: guy left behind a expensive $400 tool
07:55 PM drdoc: nice
07:55 PM XXCoder: guy just needed to buy $20 charger to have it work
07:55 PM drdoc: I think I've mentioned the uncle/cousin/clan-ancestor who cracked a chubb safe the old-fashioned way
07:55 PM drdoc: 0-0-0, 0-0-1, 0-0-2
07:56 PM XXCoder: 3 digits thats definitely possible
07:56 PM XXCoder: whoaa
07:56 PM XXCoder: https://www.forbes.com/sites/michaeltaylor/2021/05/13/ev-range-breakthrough-as-new-aluminum-ion-battery-charges-60-times-faster-than-lithium-ion/
07:56 PM drdoc: he stole his uncles tow truck, backed it through the back wall of a hardware store, hitched up the safe and dragged it through town
07:57 PM XXCoder: jeez i guess in middle of night
07:57 PM drdoc: spent 3 weeks camped out in the boonies cracking it
07:57 PM drdoc: yes
07:57 PM XXCoder: otherwise a travelibng safe would be super attention grabbing
07:57 PM drdoc: Tweddie was not the sharpest crayon on the table
07:58 PM drdoc: total gross take: $3200 or so
07:58 PM drdoc: damages his uncle made him pay the store: $7500
07:58 PM XXCoder: what a dumbass
07:58 PM XXCoder: sorry
07:58 PM drdoc: charge for 3 weeks loss-of-income on the tow truck: $5000
07:58 PM XXCoder: reading abput alum-ion batteries is amazing
07:59 PM drdoc: no problem, man
07:59 PM drdoc: Tweddie was not the sharpest crayon on the table by a long long way
07:59 PM drdoc: he and his brother both, by age thirty, had as many birthdays incarcerated as not
08:00 PM drdoc: they single (double?) handedly taught me that stealing stuff is the worst possible way to be a criminal
08:02 PM drdoc: but I dunno
08:02 PM drdoc: that one you just quoted might win
08:03 PM XXCoder: dunno but i guess can be just outside human experence to have very heavy load
08:03 PM XXCoder: i recently saw picture of guy filling a large commerical tank (same kind machine company use for coolant)
08:04 PM XXCoder: with gas, it was on trailer rated for 1000 pounds.
08:04 PM XXCoder: tank, when full, would be arounf 2000 pounds.
08:04 PM roycroft: at least he wasn't filling baggies with gasoline
08:04 PM XXCoder: it wasnt secured in any way, just laying on trailer
08:04 PM XXCoder: if he stopped halfway for 1000 pounds, it has no baffles and will have vicious waves inside it as he drives
08:04 PM XXCoder: or full and trailers breaks on way home
08:05 PM XXCoder: theres no good way out
08:05 PM XXCoder: ya saw picture of baggies. it was from 2019
08:06 PM XXCoder: though saw new video of person filling store bags, and lifting it and it leaks badly so trying to find another bag
08:07 PM roycroft: it should have been from never, ever
08:08 PM XXCoder: yeah

08:24 PM * Bleepshop does the Happy Dance...
08:24 PM XXCoder: ?
08:26 PM Bleepshop: Just got my first full profile carved part out of the router. Simple little cam-lock I'm going to run out a handfull of as stock clamps for the table.
08:26 PM XXCoder: congats
08:28 PM Bleepshop: Thank you. The ones I'm using now are plywood disks with an offset hole and another hole drilled from the edge to the center for the bar.
08:31 PM Bleepshop: Took me a bit to get the hang of Cam-Bam which is the only thing I've gotten to run and do what I want so far. Took a few hours to learn by trial/error and then it took me about as long to design/draw it as the machine took to cut the first one.
08:31 PM XXCoder: cambam isnt bad
08:32 PM XXCoder: havent tried it since days it would randomly crash lol
08:33 PM XXCoder: (program, not machine)
08:34 PM Bleepshop: Only issue I have is it bitching that I need to run it as Administrator. I am not making a freaking acount named "Administrator" on a Fedora 33 box just to try and satisfy it's wants... LOL
08:35 PM XXCoder: i really dislike programs that require admin rights
08:36 PM Bleepshop: This is the linux version. WTF is it even trying to use Win-x sysytem call handling ?
08:36 PM * Bleepshop is confused...
08:37 PM XXCoder: does program file end with exe? might be wine ran program
08:51 PM roycroft: is cam-bam still around?
08:51 PM roycroft: i thought that died off years ago
08:52 PM Tom_L: it should have
08:55 PM roycroft: maybe it really did, and bleepshop did not notice
09:32 PM Bleepshop: CamBam plus [1.0] rc-3 Linux Copyright © 2019 HexRay Ltd
09:33 PM Bleepshop: Fire it up and it throws 2 bitchy windows. First one wants a license key or continue as trial. The second one is bitching that it needs Admin rights to run.
09:34 PM Bleepshop: Still seems to function for what I need for the time being.

11:11 PM roycroft: then buy it
11:12 PM XXCoder: cam for linux is seriously lacking
11:12 PM _unreal_: more money then I'm willing to give up right now
11:12 PM _unreal_: besides my current laser is working fine
11:12 PM _unreal_: has not had much use but working fine
11:12 PM roycroft: i guess you don't want it as badly as you let on
11:13 PM veegee: CaptHindsight this particular brake rotor was still being used long after the brake pads were completely gone
11:13 PM veegee: it's insanely hard
11:13 PM veegee: The only thing that seems to be able to touch it is a grinding wheel
11:13 PM _unreal_: I want it quite badly. but I just finished building the laser etcher and that laser would require a re-design
11:13 PM veegee: I'm going to try and anneal it. Really interesting though
11:13 PM _unreal_: which I'm not about to do
