12:00 AM Xnke: oh wow
12:03 AM Xnke: Looks like linuxcnc can do rigid tapping with some fairly simple stuff
12:41 AM IchGucksLive: morning from germany
12:55 AM Tecan: https://www.amazon.com/Seating-AirGrid-Synchro-Adjustable-Managers/dp/B001EYTJEE great office chair, have had mine 20 years only had to replace the hydraulic cylinder,garden hose it once a year to clean it out.
01:00 AM IchGucksLive: off till later
01:25 AM gloops: 3 months later the thing is moving nicely around the cutting area, i can now do final levelling/squaring, skim off the supporting spars and fit a work surface
01:26 AM XXCoder: yay
01:26 AM gloops: started at xmas, maybe finished at easter
01:31 AM XXCoder: youtube+ is dead, long live iridium
01:31 AM gloops: never heard of it?
01:31 AM pink_vampire: hi
01:31 AM XXCoder: youtube changed some stuff in youtube, including treate view, popups when reading comment etc
01:31 AM XXCoder: er youtube+
01:32 AM XXCoder: but classic view dont have option now, so iridium works with new youtube view
01:32 AM gloops: hello pink_vampire
01:32 AM XXCoder: hey pink_vampire
01:32 AM XXCoder: hows things
01:35 AM pink_vampire: i got a lathe!
01:35 AM XXCoder: nice! what kind?
01:36 AM pink_vampire: old emco
01:39 AM gloops: they are popular here actually, bit of a fan base
01:43 AM XXCoder: https://www.youtube.com/watch?v=KCJ349Os3Es this type?
01:44 AM XXCoder: probably not one with milling head
01:44 AM XXCoder: small one., https://www.youtube.com/watch?v=lCv1xbk8Muw ?
01:47 AM pink_vampire: yeah similar to the green one
01:48 AM pink_vampire: but yeah.. without the mill head (but at least there is a place for it)
01:48 AM XXCoder: interesting. learning how to use lathe eh
01:51 AM gloops: you see the mill attachments come up on ebay, small machine but same principles as any lathe, you have to learn how to coax them i guess
01:52 AM gloops: https://www.ebay.co.uk/itm/Milling-Drill-Table-For-Emco-Unimat-3-4/142734008000?
01:55 AM gloops: also ripe for a control system heh
02:05 AM gloops: ive sworn every day making this router im not going to start another cnc machine, but now actually i cant wait to start on a wood lathe, a lathe will be a much more relaxed and slower pace build, but not going to give in to temptation to start yet
02:06 AM pink_vampire: wood lathe is MUCH easier just to buy
02:06 AM pink_vampire: they soo cheap
02:07 AM XXCoder: buy but can it be cnc-ized?
02:07 AM gloops: ive got a manual wood lathe, there are problems making it cnc though, in the end you are better off building one for purpose
02:08 AM gloops: its not a big thing to make a bed and a head/tailstock really, i already got a tailstock off an old lathe to go on it
02:08 AM pink_vampire: XXCoder: 2 rails on the bed and ballscrew
02:08 AM XXCoder: interesting
02:12 AM Deejay: moin
02:35 AM * Tecan >>> Auto-op est suspendu...
04:23 AM Loetmichel: Finally got the second optical switch running. I thught it would be easy, i had all parts and the software desigend for the first one... until boss bought me different optical relais... same footprint, different pinout and switch logic :-( ... alt least i have no both versions layouts and software cleaned up and saved :-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17049&g2_imageViewsIndex=1
04:53 AM jthornton-: morning
04:54 AM XXCoder: yo
04:56 AM fragalot: he
04:57 AM XXCoder: heyo
04:58 AM jthornton-: what's up this morning?
04:58 AM jthornton-: no rats here
05:03 AM XXCoder: not much. tomorrow another plumbler will come and inspect water and sewer system downstairs.
05:03 AM XXCoder: first said it was way off code
05:04 AM XXCoder: theres large sewer lift pipe but its not connected to anything
05:04 AM XXCoder: washer and dryer was added apparently but sewer system was not installed correctly
05:04 AM XXCoder: so it flows into tub sometimes
05:04 AM jthornton-: yikes
05:05 AM XXCoder: yeah. we also as well as add new water pipe upwards to ref for icemaker etc
05:05 AM XXCoder: it adds very little
05:09 AM jthornton-: I wonder if the chicken door will work today?
05:10 AM jthornton-: yesterday the lock didn't retract
05:21 AM XXCoder: hope it works
05:22 AM XXCoder: yay new engineer bruns video
05:22 AM XXCoder: rare new videp but fun
05:22 AM jthornton-: I need to get an open frame one so I can have a switch on the plunger and know it's open
05:27 AM XXCoder: that part is weird. https://www.youtube.com/watch?v=cOT71lMSlzQ
05:33 AM Tom_L: 47° and mostly dark
05:34 AM XXCoder: night
05:34 AM jthornton-: night
05:34 AM jthornton-: 55Â°F and raining
05:55 AM jthornton-: well the door worked... I wonder what happened yesterday
06:31 AM enleth: https://i.imgur.com/Q0I8zap.gifv
06:32 AM enleth: the ground sprang a leak
06:32 AM jthornton-: wow
06:35 AM fragalot: enleth: at least you know it's workin?
06:56 AM enleth: and the enclosure won't freeze over
09:02 AM Hawku-fr is now known as Hawku
09:12 AM jthornton-: damn rain
09:20 AM Roguish: hey JT. send some rain out this way, to northern Cal.
09:27 AM jthornton-: I can email you some...
09:34 AM jthornton- is now known as jthornton
10:15 AM JT-Shop: I hope I can get permanent power to the new shop this summer...
10:25 AM Rab_ is now known as Rab
11:10 AM fragalot: hi
11:16 AM JT-Shop: hi
11:16 AM SpeedEvil: That subtle sense you get when something is telling you you have grounding issues. Https://imgur.com/gallery/Q0I8zap
11:17 AM gregcnc_: boy that's a popular one
11:19 AM gloops: was reading story of an electrician who died here recently - his mated texted him jokingly saying 'are you dead?'
11:19 AM gloops: and unfortunately he was
11:21 AM gloops: street light has neutral/earth issue, it was the feed post for the street
11:42 AM IchGucksLive: hi all
11:42 AM IchGucksLive: i updated the Ubuntu 14.04 and now firerfox 56 does not support chatzilla
11:42 AM JT-Shop: use hexchat
11:42 AM IchGucksLive: i got xchat
11:43 AM IchGucksLive: JT-Shop, i woudt like to test querry is it posible at your side
11:44 AM IchGucksLive: gloops, online
11:44 AM Tom_L: your query has failed
11:45 AM IchGucksLive: chatzilla is more userfriendlie then this xchat
11:46 AM Tom_L: i've used xchat and hexchat and don't see that much difference
11:47 AM IchGucksLive: Tom_L, can you TAB me so i see if the mesage pops up on non active window
11:48 AM mozmck: I use pidgin for IRC and like it really well.
11:49 AM Tom_L: IchGucksLive, what are you trying to do?
11:49 AM IchGucksLive: ok workes
11:50 AM IchGucksLive: gloops, isend the ball passed from a Referie to the player like in US Sports
11:51 AM IchGucksLive: ok im off i got 15 gusts over the long weekend to take to the forest cycle tours
11:51 AM IchGucksLive: GN8
11:51 AM Tom_L: don't get them lost
11:53 AM holzjunkie: loetmichel: hy are you there?
11:54 AM holzjunkie: hy to everyone
11:54 AM Loetmichel: yes
11:54 AM holzjunkie: great
12:08 PM Rab: Interesting method to fixture flat parts: https://www.youtube.com/watch?v=r6DCvtcU8_M
12:09 PM sync: old news
12:14 PM gloops: just dont sit down with the superglue in your back pocket, like i did
12:15 PM Tom_L: yeah we couldn't tell if you were stuck or just lazy
12:16 PM Tom_L: so gloops, are you seeing light at the end of the tunnel yet?
12:16 PM gloops: in the car, i kind of jump out of the seat - hence coin size piece of skin came off
12:17 PM gloops: Tom_L yeah im back to the point i was at last friday, all moving, spindle working, been busy though, maybe this weekend
12:20 PM Tom_L: what stepper driver are you using?
12:24 PM gloops: ive got 2 x dm542 and 2 x tb6600
12:24 PM gloops: that bad driver cost me the last window of opportunity
12:25 PM phaxx: which one went bad?
12:25 PM gloops: the tb6600 are the upgraded version, 20kz
12:25 PM phaxx: would you recommend a TB6600 driver, generally?
12:25 PM gloops: tb6600 - didnt so much go bad, was bad out of the box
12:25 PM gloops: i cant really say ive not used one for any prolonged time
12:25 PM phaxx: I'm hitting current limits on a small gshield, DRV8818 based, and I think my machine is too beefy for those drivers so I'm looking at TB6600s
12:26 PM gloops: but the reviews seem to say they are ok
12:26 PM Tom_L: i couldn't use them anyway
12:26 PM Tom_L: 42v max
12:27 PM gloops: 4 amp 20khz 42v - according to the reviews you have to spend a lot more to get a comparable driver
12:28 PM gloops: Tom_L thats whats stated 42v - im not sure if its accurate, theyre often advertised as 50v, you know i am going to check my psu actual output, im around 40v i think
12:29 PM Tom_L: coming from china, if it says 42v i wouldn't exceed it
12:29 PM gloops: well my psu is 36v - but it gives out more, you really need to check this stuff
12:30 PM Tom_L: mine's ~48-50v
12:30 PM gloops: if close
12:30 PM Tom_L: so if i ever added a 4th axis i'd just get another gecko
12:31 PM gloops: how much are the geckos though?
12:31 PM Tom_L: quite a bit
12:31 PM gloops: yeah, i will get some if this thing turns any income
12:31 PM JT-Shop: how much is it worth to just plug it in and it works
12:32 PM JT-Shop: and works smoothly
12:32 PM Tom_L: i have geckos.
12:32 PM Tom_L: you'd be hard press to get them from me too
12:32 PM gloops: JT-Shop its worth quite a lot if the machine is making saleable things
12:33 PM Tom_L: ~150 per
12:34 PM Tom_L: https://www.ebay.com/itm/FIVE-Geckodrive-G-203V-ONE-YEAR-FACTORY-WARRANTY-steppr-motor-Drivers-W-EXTRAS-/291090769199
12:34 PM Tom_L: if you need 5
12:35 PM Tom_L: 3 for 369
12:35 PM gloops: $100 each? compared to $5 for tb6600
12:35 PM Tom_L: 5 bux!!?
12:36 PM gloops: yeah thats how much americans get them for lol
12:36 PM gloops: theyre about ÂŁ7 here
12:36 PM pink_vampire|2: 5$!!
12:36 PM gloops: 5$ take it or leave it
12:37 PM fragalot: that's a price where you just bulk buy them
12:37 PM gloops: yes actually mine were $10 - as only 1 was good haha
12:37 PM Tom_L: they probably don't have anything special about them either
12:37 PM pink_vampire|2: my 3d printer head use one of the tb6600
12:37 PM Tom_L: like idle current shutdown etc
12:38 PM Tom_L: morphing
12:38 PM pink_vampire|2: https://i.imgur.com/xQB0dYk.png
12:38 PM gloops: i dont know which driver they ripped off, but the motors on the tb6600s are cooler than the ones on the dm542 - which is 6 times the cost
12:39 PM Tom_L: mine barely get above room temp
12:39 PM Tom_L: but i'm not running them at 5A either
12:40 PM Tom_L: until i start stalling them i see no need to
12:40 PM gloops: yeah that looks familiar pink_vampire - the new ones have the dipswitches on the side just for that added bit of frustration
12:46 PM gloops: looks like the original tb6600 was Toshiba
12:54 PM fragalot: https://www.youtube.com/watch?v=oNtvBufTTfA
12:54 PM fragalot: love it
12:56 PM gloops: seen that one, im not sure what channel it was, maybe this one, there was a lock freak
12:57 PM gloops: could go in B&Q and open any lock, padlock, deadlock, upvc doors anything
12:57 PM fragalot: not that hard really
12:57 PM fragalot: all locks do is keep honest people out
12:58 PM gloops: true yeah, i didnt realise the extent of it, they have international competitions and stuff
12:58 PM fragalot: Yup
12:58 PM gloops: 2 open end spanners force a lot of cheap padlocks
12:59 PM fragalot: or a beer can, or a sharp poking implement
12:59 PM gloops: beer can?
12:59 PM fragalot: or if it's a master lock, basically anything that fits into the keyhole
12:59 PM Rab: The guy claims that the saw is constructed from braided stainless wire which has been "roughened", but I can see that's not so from the video. Each braided wire has a smaller wire coiled around it. I wonder what that material is.
12:59 PM fragalot: even chicken bones
12:59 PM fragalot: Rab: it's just stainless wire wrapped around a thicker stainless core
01:00 PM fragalot: you're supposed to make a bow saw with them, not do what he did.. but that's not the point of the video :P
01:00 PM fragalot: gloops: you cut the can up & make shims that push the locking palls away
01:01 PM Rab: I guess that's not going to work on anything hardened. He says the lock in the video is cast zinc.
01:01 PM fragalot: Rab: it won't work on anything harder than cheese. :)
01:01 PM fragalot: those cast zinc locks are pretty, but you can open them with pretty much anything
01:02 PM fragalot: including a blowtorch
01:02 PM Rab: Seems like a smack from a hammer would be enough, if you want to trade speed for minor damage to the rotor.
01:02 PM gloops: they had a lock in the local pit yard stores which was said could not be ground or burned off, no hope of forcing it - during the miners strike it lasted right till the end about 9 months, but someone did get it off lol
01:03 PM FinboySlick: This is my favorite master lock opening trick: https://www.youtube.com/watch?v=pU9MB5XPsp4
01:03 PM FinboySlick: No traces, no scratches, nothing.
01:05 PM gloops: 2 spanners https://www.youtube.com/watch?v=1jJP0CcuJyE
01:07 PM JT-Shop: a plastic lock
01:07 PM gloops: i think theyre also chinese spanners heh
01:08 PM holzjunkie: JT-Shop: thx to you the package arrived today
01:08 PM JT-Shop: great
01:08 PM JT-Shop: now the fun begins
01:08 PM holzjunkie: so it seamÂ´s
01:09 PM holzjunkie: anyone here who made an retrofit on san
01:09 PM holzjunkie: an Maho MH millingcenter?
01:17 PM fragalot: holzjunkie: I want to say miss0r but i'm not sure..
01:21 PM holzjunkie: ok thx for the tip
01:23 PM holzjunkie: https://www.youtube.com/watch?v=MxBBN7-1QR4
01:23 PM holzjunkie: anyone knows him???
01:25 PM gloops: not seen him anywhere, not by that name anyway
01:26 PM Rab: Not I, but that's a tough-looking control enclosure (with some really cheap-looking pushbuttons).
01:26 PM fragalot: xD
01:29 PM holzjunkie: thatÂ´s not the poi the poi is the programming and wiring
02:03 PM gloops: lol true https://ibb.co/d3AW9n
02:04 PM gloops: hmm, what has linux got to offer in the way of scroll drawing apps
02:16 PM JT-Shop: I thought we had one here but https://github.com/linuxcnc/simple-gcode-generators
02:16 PM JT-Shop: don't see one
02:22 PM andypugh: What be ye looking for?
02:24 PM JT-Shop: either my probe is rubbish or there is some trash in the spindle bore
02:26 PM gloops: i was looking to see if linux had any kind of spiral/scroll drawing app, seems inkscape and gimp are what we have
02:28 PM andypugh: You could probably do something very clever with parametric nurbs and G5, G5.1 or G5.2 : http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g5.2-g5.3
02:29 PM Rab: gloops, 2D? Inkscape + gcodetools seems adequate.
02:30 PM gloops: yes inkscape can do it, very good drawing app
02:38 PM JT-Shop: nice everything I slap in the spindle has 0.003 TIR
02:45 PM andypugh: mm? (He asks hopefully)
02:50 PM FinboySlick: JT-Shop: But not the spindle itself?
02:52 PM FinboySlick: Stick a boring bar in the vise and re-do your spindle taper. Just be sure not to screw up ;)
02:55 PM JT-Shop: it's a kwik switch spindle can't measure the spindle itself
03:01 PM JT-Shop: FinboySlick: I don't think the taper is the problem it's out of line through the two tabs on the holders like the nut is screwed
03:26 PM Tom_L: JT-Shop, did you hit something hard with it?
03:28 PM gloops: gauge need calibrating? anything else out by that much
03:31 PM andypugh: I am wanting to make my own coaxial indicator. I have decided that the commercial ones are too long.
03:31 PM andypugh: Itâ€™s mainly because they use a stock full-size clock with a normal-length stem.
03:31 PM Tom_L: i would be up for that since i've got a small mill and limited z
03:32 PM Tom_L: although i've managed to get by without one so far
03:34 PM cradek: andypugh: make a probe instead?
03:34 PM andypugh: I have a probe.
03:34 PM andypugh: They both have their uses
03:34 PM JT-Shop: Tom_L: when I hit something the head just moves lol
03:35 PM andypugh: By the way, here is my â€śtop tipâ€ť for coaxial indicators: http://www.model-engineer.co.uk/forums/postings.asp?th=131421
03:47 PM JT-Shop: well it seems like you can disassemble a kwik switch nut from the spindle... gave it a good cleaning
03:47 PM XXCoder: hey andypugh
03:48 PM andypugh: Hai
03:48 PM XXCoder: funny video btw heh
03:52 PM fragalot: andypugh: here's where most coaxial indicators belong, imho: http://preview.turbosquid.com/Preview/2014/07/10__04_51_43/render_dustbin_6_vray_001.jpg1ad99154-e5c7-4340-bdc9-d12f7ac5d1a3Original.jpg
03:53 PM XXCoder: coaxial indicator?
03:53 PM fragalot: The idea is sound, but indicator droop is a real thing, and quite bad on those things..
03:53 PM andypugh: fragalot: They are quite clever, though. Everything ought to cancel out
03:54 PM fragalot: they are indeed clever, and I am sad that they are so unreliable
03:54 PM andypugh: And unlike a probe they do measure relative to the spindle axis.
03:54 PM fragalot: at least in my experience
03:54 PM andypugh: (giaranteed by geometry)
03:55 PM fragalot: drill a hole, bore it out, without moving table, check that hole with a coaxial
03:55 PM fragalot: I guarantee it will be off
03:59 PM andypugh: Maybe, but it will probably be least-off at the original position.
04:00 PM Deejay: gn8
04:00 PM XXCoder: hes out
04:02 PM XXCoder: I think hes saying that it will be off even if hole is at orginial position
04:02 PM XXCoder: meaning something off about that type of indictor. dunno I dont own one of those coaxial indictors
04:15 PM Tom_L: andypugh i see ikea is watching over your indicator too
04:16 PM XXCoder: tom I have one ready for usage on my cnc router. havent added it yet though
04:16 PM XXCoder: its fanastic light for that usage and cheap also
04:17 PM Tom_L: i've got one over the drill press and one over the lathe
04:18 PM gregcnc_: the switches in mine are shite
04:18 PM XXCoder: lol my desk one switch broke in short time
04:19 PM XXCoder: I just rewired it direct and unplugged when not using it
04:19 PM XXCoder: how old yours is? mines at 5 to 6 years I guess?
04:20 PM gregcnc_: 8 yrs maybe, dunno
04:21 PM XXCoder: I wonder if they fixed it
04:21 PM XXCoder: actually oops mine is almost as old as yours at 7 years.
04:21 PM JT-Shop: what light is that?
04:22 PM XXCoder: the ikea light. forgot name but its very cheap and sold for long time by now
04:22 PM XXCoder: $10 led desk light
04:22 PM JT-Shop: don't have ikea here
04:22 PM Rab: Looks like JANSJĂ–: https://www.ikea.com/us/en/catalog/products/70291232/
04:23 PM XXCoder: thats usb version. didnt know one existed
04:23 PM Rab: AC version: https://www.ikea.com/us/en/catalog/products/90386328/#/80386319
04:23 PM XXCoder: https://www.ikea.com/us/en/catalog/products/50386066/
04:24 PM XXCoder: im considering this https://www.ikea.com/us/en/catalog/products/20277139/ for right under gantry
04:24 PM JT-Shop: ah amazon has them
04:24 PM XXCoder: or maybe https://www.ikea.com/us/en/catalog/products/20119418/
04:25 PM XXCoder: yeah some people (or maybe ikea itself) resells stuff at amazon
04:25 PM JT-Shop: only higher than ikea lol
04:27 PM Tom_L: ikea will ship to you
04:27 PM JT-Shop: $29
04:27 PM Rab: I like these things, the color isn't great (kinda blue) but they're bright and the mag base is great: https://www.ebay.com/itm/281993172871
04:27 PM Tom_L: that sucks
04:30 PM XXCoder: LOL guniknife https://www.ebay.com/itm/1PC-Tactical-Folding-Blade-Knife-Survival-Hunting-Camping-Pocket-Knife-With-LED-/272410473175
04:31 PM XXCoder: when will we have knifegun? one that shoots knifes :P
04:32 PM Rab: I doubt that's making it onto the plane.
04:32 PM XXCoder: Rab: I remember reading about guy who had "gun" tattoo look like stick down pants
04:33 PM XXCoder: combine that with "I love guns" shirt at airport

04:36 PM Tom_L: i wonder how something like that would do for a spindle motor
04:36 PM gloops: that would work in the coolant
04:37 PM gloops: if you wanted a really close look inside the coolant region for example
04:39 PM XXCoder: something like this, not sure if actually same guy https://i.pinimg.com/736x/43/a1/0c/43a10cdaec0702dadc45f6ef8117a35f--pistol-tattoos-gun-tattoo-men.jpg
04:42 PM gregcnc_: Tom_L 3000 RPM is a bit limiting
04:43 PM Tom_L: i've got belts on my current one to step it up slightly
04:45 PM JT-Shop: crap spent all day making a stupid part and my hole pattern is for the RPi camera so my fish eye won't fit
04:46 PM gregcnc_: huh, 3kRPM is rated, but the manual shows 5k max
04:47 PM andypugh: XXCoder: how about a Spork gun? http://www.girlgeniusonline.com/comic.php?date=20081015#.Wr1ekGaZNdA
04:47 PM Tom_L: not having to look for a supply for it is a plus
04:48 PM XXCoder: andy lol yeah forgot about that one. funny
04:48 PM Tom_L: gregcnc_, where do you find the manual
04:48 PM Tom_L: ?
04:49 PM gregcnc_: https://www.automationtechnologiesinc.com/products-page/ac-servo-motors/ac-brushless-servo-motor-and-driver/
04:49 PM andypugh: The AC powered JansĂ¶ comes with a 4V wall-wart. But they run perfectly on 5V (at the exact same current, I checked)
04:49 PM andypugh: Mine have been running at 5V for years.
04:50 PM XXCoder: nice to know
04:55 PM Loetmichel: andypugh: the tops get hotter though
04:55 PM Loetmichel: i think there is a current regulator in there
04:56 PM andypugh: You can spray coolant on them :-)
04:56 PM Loetmichel: a linear one
04:57 PM gloops: what kind of con job is this https://www.ebay.co.uk/itm/YASKAWA-SGMDH-45A2B-YR14-NEW-AC-SERVO-MOTOR-SGMDH45A2BYR14/312098547586?
04:57 PM Loetmichel: i do occasionally. i have one on my mill: http://www.cyrom.org/palbum/main.php?g2_itemId=12223
04:58 PM XXCoder: looks like it might have encoder but dunno
04:58 PM XXCoder: looks weird
04:59 PM gloops: ÂŁ1.11 bid, click on item description 1200 euros
05:00 PM XXCoder: huuuuh
05:01 PM XXCoder: its bid item and "no bids! all bids will be removed"
05:01 PM XXCoder: it may be way to go around ebay fees.
05:01 PM andypugh: You know that â€śreport listingâ€ť link? I just used it.
05:01 PM XXCoder: me too
05:03 PM gloops: looks like hes been on ebay a while, lots of feedback, bit much to expect that for ÂŁ1.11 though lol, but still..
05:03 PM XXCoder: guy dont expect bids.
05:03 PM XXCoder: in fact person said so'
05:03 PM gloops: it makes you look though, wouldnt have looked if buy it now was 1200
05:04 PM XXCoder: and would not cost person fees at all
05:04 PM gregcnc_: somebody trying to take advantage of the mobile coding
05:04 PM XXCoder: $1 list fee is very small if not free, and buys would happen outside ebay
05:04 PM gloops: right
05:04 PM XXCoder: too bad because "long time member"
05:20 PM Tom_L: the last pic he ever took: http://www.airventure.de/Layout/404.jpg
05:21 PM XXCoder: it may be possible to escape that
05:21 PM XXCoder: found page its from, though cant read that language
05:22 PM gregcnc_: photchop
05:22 PM XXCoder: text says nothing about photo
05:31 PM andypugh: Reminds me of this classic clip: https://www.youtube.com/watch?v=Wpq4Tu2NnrQ
05:34 PM Tom_L: i witnessed similar with a B1 here one 4th of july
05:35 PM Tom_L: sitting on the back side of a bridge you couldn't see it coming up the river path until it was over your head at low altitide
05:35 PM Tom_L: wasn't quite that low though
05:36 PM Tom_L: the B2 are just erie to watch
05:37 PM XXCoder: andy dang pretty risky
05:40 PM XXCoder: https://www.youtube.com/watch?v=Jct33SgQofY fun
05:50 PM gloops: https://www.youtube.com/watch?v=27_nSTgag-w i wonder what the pilot does while this is happening, just close his eyes and bite on something
05:51 PM andypugh: XXCoder: Several years ago I did a web search to find if anyone had ever actually made a chocolate teapot. I found: https://www.plokta.com/plokta/issue23/teapot.htm
05:52 PM XXCoder: lol. too bad its not that famous teapot
05:52 PM XXCoder: Utah teapot
05:52 PM XXCoder: https://en.wikipedia.org/wiki/Utah_teapot
05:53 PM gregcnc_: Gloops they can control that
05:53 PM andypugh: Which was very amusing to me, as I know all the authors really well. (As in we used to all go to New-Year parties at the Baker, Brignal & Clements house)
05:53 PM gregcnc_: real life https://www.youtube.com/watch?v=IhiUFCagFdI
05:54 PM andypugh: XXCoder: Have you heard of â€śRussellâ€™s teapotâ€ť ?
05:55 PM XXCoder: https://frieslandversand.de/teekanne-1-4l-weiss-utah-teapot?number=1209034011 apparently still buyable
05:56 PM XXCoder: ah yeah didnt remember name but remember concept
05:56 PM gloops: gregcnc i couldnt, looking at those moves, the disorientation, g force, no way you would even know your global position
05:56 PM gregcnc_: they are model aircraft
05:58 PM gloops: lol oh yeah! i thought they were funny colours for a mig
05:59 PM gregcnc_: the link you posted was a pc simulator for model flying
05:59 PM gregcnc_: https://www.youtube.com/watch?v=JHJs1gBLiuQ
05:59 PM gloops: it came up from one of the other vids above, i just clicked
06:15 PM skunkworks: http://electronicsam.com/images/house/TrackPress.JPG
06:18 PM Tom_L: :)
06:21 PM skunkworks: 2000psi = 80,000lbs force
07:23 PM andypugh: Have you guys seen the magnetic metal folders? I was unaware of them until last week. (I know rene-dev is, it was he that told me about them): https://youtu.be/OipSiPSRti8
07:30 PM jdh: I like the lab ooat
08:02 PM andypugh: Cheap DIN rail brackets (this is for 10 of them) https://www.ebay.co.uk/itm/282705731350
08:02 PM andypugh: They are intended for SSRs, but there is plenty of metal left for drilling other holes.
08:03 PM XXCoder: cutting with former plate https://www.youtube.com/watch?v=azbzAxxflO8
08:06 PM andypugh: Thereâ€™s something wrong in his head
08:09 PM CaptHindsight: https://www.jthomasparts.com/255-139x-electric-pto-clutch where do the lawn tractors use these?
08:10 PM CaptHindsight: for the mower blade or power to the wheels?
08:10 PM andypugh: In the PTO?
08:10 PM andypugh: Power Take Off (to the mower or attachments)
08:11 PM CaptHindsight: $100 for an electric clutch
08:12 PM andypugh: I am not sure if that is cheap or expensive. Look for a car air-conditioning clutch.
08:12 PM CaptHindsight: never inspected a lawn tractor that closely
08:14 PM CaptHindsight: https://www.ebay.com/i/172520404697 $40
08:15 PM Tom_L: i wonder how hard those are to remove
08:15 PM Tom_L: i'm thinking i've got one that's bad
08:16 PM CaptHindsight: https://www.youtube.com/watch?v=URqFd3KkSRY video of doing so
08:16 PM Tom_L: haven't had time to check into it that much
08:17 PM Tom_L: wonder if that can be done without unhooking the lines
08:18 PM CaptHindsight: if you can fit the pullers in there
08:18 PM Tom_L: maybe
08:18 PM gregcnc_: are you fixing ac or tractor?
08:18 PM CaptHindsight: frame, radiator etc have enough clearance?
08:19 PM Tom_L: more like wheel well
08:19 PM CaptHindsight: gregcnc_: me I'm just looking for cheap electric clutches for a ~10 rpm machine
08:20 PM gregcnc_: much torque?
08:21 PM CaptHindsight: 20Kg rotating axial load
08:22 PM CaptHindsight: plant life, so it's not perfectly balanced
08:22 PM CaptHindsight: so not much, stepper driven
08:22 PM gregcnc_: making sure your plants grown nice and straight?
08:23 PM CaptHindsight: heh, no these are post plucked
08:23 PM andypugh: I once built a machine with a pneumatic clutch that engaged a cam onto a 100kg flywheel doing 3000 rpm.
08:24 PM andypugh: Designed to get a compression testing machine from 0 to 80 kph in 10mm
08:24 PM gregcnc_: I've looked at Ogura before but we didn't end up needing one.
08:24 PM CaptHindsight: AC clutch might be the cheapest if making the parts it attaches to is also cheap
08:24 PM andypugh: It would either do that, or destroy itself. That has to be the scariest mouse-click of my career to date.
08:25 PM gregcnc_: i woudl think so anything else will be costly
08:25 PM CaptHindsight: the PTO clutches have mounting holes
08:26 PM andypugh: But, anyway, I mullered my back today. Just standing still. my enthusiasm for anything buy laying in a horizontal posture now has disappeared.
08:26 PM andypugh: Goodnight.
08:26 PM CaptHindsight: not fun
08:26 PM CaptHindsight: mullered, new one
08:28 PM Tom_L: to grind to powder, pulverise or crumble.
08:28 PM Tom_L: that's a bit extreme
08:29 PM CaptHindsight: ever pinch a nerve in your lower back of damage a disc?
08:29 PM CaptHindsight: of/or
08:29 PM Tom_L: no but i did in C6 C7
08:30 PM XXCoder: had crunchy glass feeling back beforee
08:30 PM CaptHindsight: I remember not being able to move for a few days
08:30 PM XXCoder: its no fun
08:30 PM Tom_L: took ~month to get back to somewhat normal
08:31 PM gregcnc_: seems york type have a flange for the coil? is that what you are after https://www.ebay.com/itm/162928431892
08:33 PM CaptHindsight: have to hold it somehow
08:33 PM gregcnc_: never had to deal with one
08:33 PM gregcnc_: others are pressed on?
08:34 PM CaptHindsight: often
08:35 PM CaptHindsight: or snug fit on a shaft with a key and nut
08:36 PM CaptHindsight: have other options as well
08:37 PM CaptHindsight: also have to weigh the parts at the same time
08:37 PM gregcnc_: weighing an unblanced load sounds tough
08:38 PM CaptHindsight: will weigh it before rotating
08:38 PM gregcnc_: ok
08:38 PM CaptHindsight: load it in the basket, get weight, start motion
08:39 PM CaptHindsight: like hanging produce scale at the market, only this has to also rotate a few times
08:39 PM gregcnc_: you do random contracting work or is it related somehow?
08:39 PM CaptHindsight: almost never the same machines
08:41 PM gregcnc_: keeps it interesting
08:42 PM CaptHindsight: concept to production hand off
08:43 PM gregcnc_: all yourself?
08:43 PM CaptHindsight: automated xmas tree trimmer :)
08:43 PM gregcnc_: lol
08:44 PM CaptHindsight: mostly me
08:45 PM CaptHindsight: rare that anything is really complicated, but most customers find it to be magic
08:46 PM gregcnc_: if they could build it they would, i suppose
08:47 PM CaptHindsight: often they have tried after wasting your time months earlier
08:47 PM CaptHindsight: some don't know what they want
08:47 PM CaptHindsight: have budget and rough idea
08:48 PM CaptHindsight: then they get angry later when they find something with 1/10 the precision or specs is 1/4th the price
08:48 PM gregcnc_: getting specs in writing is difficult at times, i work with a guy who is vague sometimes
08:49 PM CaptHindsight: ask for formula 1 car, really need a Chevy malibu
08:49 PM CaptHindsight: they pay for specs if they have them
08:50 PM CaptHindsight: sorry of they don't have them
08:50 PM CaptHindsight: can't make anything to spec without specs
08:50 PM CaptHindsight: the worst ones don't want to have specs
08:51 PM CaptHindsight: just do this and this :)
08:51 PM CaptHindsight: and then they want something else when you're done
08:51 PM CaptHindsight: so you have to hold them to specs, unless they are a trusted old client
08:52 PM gregcnc_: my guy is brilliant with physics, but building stuff he does with hammer and chisel so sometimes doesn't get why something is not so easy
08:52 PM CaptHindsight: the bad client is the expert that claims how hard something is
08:52 PM gregcnc_: I cringe when I get parts back for repair or modification, sometimes they look like they fell out of a truck on rush hour
08:53 PM CaptHindsight: or acts like a school professor, wants all the math
08:53 PM CaptHindsight: lol
08:53 PM gregcnc_: he's great otherwise, not his money so that' never a sticking point
08:54 PM CaptHindsight: I never get involved in any contests
08:54 PM CaptHindsight: bait to get free design work
08:55 PM CaptHindsight: like it's some challenge
08:55 PM gregcnc_: I got sucked into a project that was in something I had interest in. Became obvious it was a product development not a friendly fun build, finally walked away.
08:55 PM CaptHindsight: I'm sorry that you asked a bunch of stupid people first
08:56 PM CaptHindsight: I only work on prepaid/funded projects
08:57 PM CaptHindsight: and you don't get the designs or machines until they are paid for
08:58 PM CaptHindsight: sometimes I get requests for things worth millions/billions if it works
08:59 PM CaptHindsight: and they wonder why it will cost so much to develop
09:00 PM gregcnc_: right, easy money just pass along the info as you figure it out
09:00 PM CaptHindsight: gregcnc_: ever get those customers that are just "better than you" and they just deserve any gains from it?
09:01 PM CaptHindsight: you are just a slave
09:01 PM gregcnc_: not dealt with anyone like that
09:01 PM gregcnc_: last job I had tough they offered a bonus based on sale of a product line I was developing/supporting
09:02 PM CaptHindsight: or how they think that all engineers and scientists are just the same, like you're just working a copy machine or pulling a handle
09:02 PM gregcnc_: when he gave me the check he said "woah, that's a lot"
09:02 PM gregcnc_: never mind the company had it's biggest year ever
09:03 PM CaptHindsight: yeah, they just collect money, and never want to share any
09:03 PM CaptHindsight: like a 4 year old with candy
09:04 PM gregcnc_: then i got reprimanded for spending on priority mail vs first class to keep a customer happy
09:04 PM CaptHindsight: when I was around 20 I answered a job posting for a service tech
09:04 PM gregcnc_: and they profited something like 15k$ on shipping charges that year
09:05 PM CaptHindsight: paid like $60k a year
09:05 PM CaptHindsight: I passed the test with the gear but then the boss said, what does a 20 year old need that much money for?
09:06 PM CaptHindsight: thanks for the warning and left
09:06 PM gregcnc_: wtf
09:07 PM CaptHindsight: most contact through open source want work for free
09:09 PM gregcnc_: eh, time to watch some cartoons and go to bed
09:09 PM CaptHindsight: hasta
