12:30 AM fragalot: hi
01:37 AM fragalot: hi IchGucksLive
01:37 AM IchGucksLive: morning from sunny cold germany
01:44 AM miss0r: Shop cleaning time... Then on to some electrical stuff :]
01:44 AM fragalot: :o
01:44 AM IchGucksLive: im off Breakfest time here as we now serve gusts
01:45 AM fragalot: my concrete vibrator arrived
01:45 AM fragalot: it has that nice chinesium stank to it
01:45 AM miss0r: fragalot: it made an unholy mess in here when I made that box for the compressor...
01:45 AM miss0r: LOL
01:46 AM fragalot: haven't even opened the box and I could smell it, lol
01:46 AM miss0r: did you open the box with a blow torch, or did it just smill like that from the factory ? :D
01:46 AM fragalot: miss0r: i'm going to have at it with a weed trimmer, yank it out by the power cord, and shout "TIME!"
01:47 AM miss0r: ;)
01:47 AM miss0r: Is there any other way to do it properly ?
01:48 AM fragalot: well you could use any variety of garden tools, really
01:48 AM fragalot: or the shop press.. Lathe should be possible, but tricky
01:48 AM miss0r: or.. OR.. you could attach aluminium tape around the box and use the plasma cutter :D
01:48 AM fragalot: chuck up a blade in the lathe, present the box to it
01:48 AM fragalot: miss0r: yes. let's do that!
01:49 AM fragalot: I have a small issue with my plasma though
01:49 AM miss0r: AvE already beat us to that as well ;D
01:49 AM fragalot: I can only go about 15cm before I have to wait for the compressor to catch up, lol
01:50 AM miss0r: sucks :]
01:50 AM fragalot: a little
01:50 AM miss0r: For the same of my economy, I've bought a brady model 21. I'm going to use that selflaminating labels you spoke about
01:51 AM miss0r: I'll give it a shit atleast
01:51 AM miss0r: shot.. I ment shot :D
01:51 AM fragalot: I thought you hated those?
01:51 AM miss0r: I do. But I've been told theres a new glue involved, that should be alot better than the one I used to hate
01:51 AM miss0r: So, I'll do some testing
01:52 AM fragalot: Good luck :-)
01:52 AM miss0r: Either way, its going to be alot cheaper for me to use than alot of other stuff. And my boss is a cheap mofo...
01:52 AM fragalot: very true
01:53 AM fragalot: and you can apply it after the fact when you forgot one, or when you inevitably spot a mistake / change your mind
01:53 AM miss0r: I cannot recognize ANY of thoes examples
01:54 AM fragalot: I've always wondered how well those permasleeve things work
01:55 AM fragalot: miss0r: you don't happen to know where I could find JIS screwdrivers, would you?
01:57 AM fragalot: nvm found an auto parts store that carries 'm
01:57 AM fragalot: I'm off - ttyl
01:58 AM miss0r: cya
03:09 AM Deejay: moin
03:13 AM gloops: howdy
03:33 AM miss0r: This electrical drawing is coming along a bit slow. I just can't seem to pull myself up today
03:34 AM gloops: stress
03:35 AM miss0r: nah :] I just didn't get much sleep last night. I've got a kid little over 2 years, with a cold that made him cough and wake up a million times
05:00 AM gloops: new steppers got here quick, look pretty substantial, wont know if they work for a while though
05:57 AM jthornton: dang slept in
05:58 AM XXCoder: your rooster failed his duty, meal time. ;)
06:00 AM jthornton: coq au vin
06:44 AM gloops: lol, though id smoked vfd there, plugged in, tripped mains
06:45 AM gloops: couldnt find anything, used a different socket - lights up normally
06:45 AM gloops: must be damp in socket i reckon
06:54 AM jthornton: got lucky
06:54 AM gloops: well, i havent actually run anything off the vfd again yet, but it is lit up normally, could still be kaput
07:05 AM jthornton: I hope the weather improves for the weekend so I can finish splitting firewood for the year and put the splitter up
07:11 AM gloops: improving here but rumours of another cold blast coming, ill be glad to see the back of this winter
07:11 AM jthornton: I hear ya this has been a very cold winter for sure... maybe it killed off some bugs
07:14 AM malcom2073_: We just got a foot of snow, which suits, first day of spring and all
08:52 AM miss0r: Coffee bean & water 2$
08:52 AM miss0r: Electricity to brew a can 0.2$
08:52 AM miss0r: Forgetting the coffee and now its cold, priceless
08:53 AM gregcnc: that's premium beans, water, and electrons or does everything cost that much there?
08:54 AM miss0r: Just guessing here(didn't do any calculations), but that being said, I only use premium beans ;)
08:56 AM miss0r: My boss drives me to the ground, but he buys good coffee :]
08:57 AM gregcnc: I buy locally roasted, but the last bag was well below their typical standard
08:57 AM charlesh: Trying to bridge a gap here, I have a 5i20 card and 2x7i40 hbridges. What’s the best card to take those encoder signals?
08:59 AM charlesh: I have a 7i37ta for my IO
08:59 AM charlesh: Simple 3 axis machine
09:01 AM miss0r: It seems theres no mesa people around sadly
09:03 AM charlesh: So it would seem
09:08 AM miss0r: gregcnc: The reason I forgot about the coffee was because I was turning a fitting to go from my shot air system to a salvaged manometer. Turns out the manometer was broken heh
09:08 AM miss0r: shot=shop
09:08 AM gregcnc: if i forgot about coffee time would stand still
09:09 AM miss0r: I felt the same way. That combined with the fact that what I was doing while forgetting the coffee was all a waste.. so waste^2
09:38 AM skunkworks: gregcnc, what video?
09:38 AM gregcnc: mazak
09:38 AM skunkworks: heh - you tube? That was dad..
09:40 AM skunkworks: https://www.youtube.com/watch?v=zTwQ3vRuQDs
09:40 AM skunkworks: it doesn't get much use lately. still running the T2 control. Dad is the only one that knows how to program it.
09:42 AM skunkworks: got it for a song. Had a bad x servo
09:43 AM gregcnc: do much work or just keep stuff around to play with?
09:44 AM skunkworks: mostly 2nd... it is his retirement fun.
09:44 AM skunkworks: (and my r&d escape)
09:53 AM miss0r: i've long wanted a boring bar with 'some' reach that can do as small as 6+mm holes
09:54 AM miss0r: Can you guys recommend something that is good?
10:03 AM miss0r: I think I should find a solid carbide indexable boringbar
10:03 AM gregcnc: you can get indexables down to 4mm or so
10:13 AM miss0r: The prospect of grind one myself out of carbide is daunting
10:21 AM IchGucksLive: hi it is quite sunny here but cold
10:22 AM IchGucksLive: ni hao jimmylu2333-fedo
10:29 AM IchGucksLive: till later
10:33 AM BitEvil_ is now known as SpeedEvil
12:00 PM miss0r: Can anyone in here recommend a brand/place to buy a 5-6mm solid carbide indexable boring bar?
12:02 PM Jymmm: miss0r: dollar store (or in your case iirc the pound store) =)
12:03 PM miss0r: Jymmm: almost; This is the Kroner store (Danish)
12:03 PM Jymmm: miss0r: oh that's right... my bad
12:04 PM miss0r: I just can't seem to find any. All the ones I can seem to locate are just steel shanks.
12:06 PM methods_: yeah why would you need a carbide boring bar that's insertable?
12:07 PM methods_: oh sorry indexable
12:07 PM miss0r: Because with most steel boring bars, I can only do a 4:1, and with a carbide shank I can push that closer to 8:1 (stickout:shank diameter)
12:07 PM methods_: what do you mean by indexable in this situation?
12:07 PM miss0r: It takes inserts
12:08 PM methods_: yeah they usually don't make carbide boring bars that are insertable
12:08 PM methods_: that might be very hard to find
12:08 PM miss0r: not realy. Theres plenty. I just can seem to find a seller offering a 5-6mm one
12:09 PM methods_: have you looked into these?
12:09 PM methods_: https://www.sandvik.coromant.com/en-gb/products/coroturn_xs
12:09 PM miss0r: mitsubishi carbide makes'em, but I can't find a seller
12:09 PM methods_: ah ok
12:09 PM miss0r: yeah, not realy what I want
12:10 PM miss0r: If I can't get the one I want, I might as well make my own I guess
12:10 PM miss0r: but the time needed X(
12:10 PM methods_: yeah
12:13 PM methods_: https://www.widia.com/content/dam/kennametal/widia/common/resources/downloads/literature/WIDIA%20Catalogs/A-09-02078_Widia_Turning_inch_p178-343_Circle.pdf
12:13 PM methods_: widia might have one you want
12:13 PM methods_: looks like the have smaller dia shank indexables
12:13 PM miss0r: hah, amazon has the one I want: https://www.amazon.com/Mitsubishi-Materials-C05HSCLCR03-Micro-Dex-Rhombic/dp/B01EKJCM8E
12:14 PM methods_: amazon to the rescue
12:14 PM methods_: too bad it's out of stock lol
12:14 PM miss0r: yeah
12:21 PM IchGucksLive: hi
12:27 PM Deejay: bbl
01:01 PM Tom_L: http://maxtoolinc.com/C05HSCLCR03-P277825.aspx
01:01 PM Tom_L: miss0r
01:04 PM Tom_L: hah, i bet it's the same company: http://www.carbidedepot.com/C05HSCLCR03-P277825.aspx
01:10 PM gregcnc: miss0r not Iscar rep in EU? http://www.iscar.com/eCatalog/item.aspx?cat=6862271&fnum=326&mapp=IS&app=30&GFSTYP=M&isoD=1
01:20 PM Tom_L: http://www.iscar.com/newarticles.aspx/countryid/1/newarticleid/202
01:20 PM Tom_L: http://www.iscar.com/newarticles.aspx/countryid/1/newarticleid/219
01:21 PM Tom_L: give us your cc and we'll order it for ya too
01:21 PM fragalot: hi
01:21 PM FAalbers: ho
01:22 PM Tom_L: still puzzled about my work offset thing
01:22 PM Tom_L: seems like it wanted a linear move in Z before it would accept the new offset
01:22 PM fragalot: is that when you put something off until tomorrow?
01:26 PM gloops: new motors turned up, quite a different thing to chinese nema 23s..
01:27 PM Tom_L: in a good way?
01:27 PM fragalot: they're italian, which means that they may work,.. or they may not. depends on what the weather is like
01:27 PM gloops: shaft at rear is 20mm with big bearing, all round a lot more robust, hope they work now heh
01:27 PM Tom_L: working is always a plus
01:28 PM Tom_L: maybe i'll go out and see if i can break a cutter..
01:28 PM gloops: come with 2 30mm pulleys anyway so thats something if they dont - cant see any reason they wont not marked, turn fine etc
01:33 PM gloops: i might be running tommorrow, if i feel energetic when i get up
01:48 PM miss0r: Looking forward to some videos of it gloops
01:49 PM miss0r: gregcnc: I don't know any local dealer
01:50 PM fragalot: miss0r: join the club? :P
01:50 PM miss0r: Tom_L: yeah, its just that the import tax will kill me
01:50 PM miss0r: hello fragalot
01:50 PM fragalot: 'sup?
01:51 PM miss0r: Just 'unstuck' my saw... Vacuumed the shop floor, cleaned the lathe & the mill
01:52 PM miss0r: The usual Wensday stuff. (apart from fixing the saw)
01:53 PM miss0r: Also, I've been browsing around for a solid carbide boring bar for inserts, that can go down to 5-6mm ID
01:53 PM fragalot: with inserts?
01:53 PM miss0r: yeah
01:53 PM fragalot: not sure if they exist that small
01:53 PM miss0r: This one in particular: http://maxtoolinc.com/C05HSCLCR03-P277825.aspx
01:53 PM miss0r: they do ;)
01:55 PM miss0r: In this particular case I could've gotten away with a 1/4" reamer, but I didn't have one. Next time I'd like to just be able to turn it straight off the bat
01:55 PM fragalot: brb, running to the tool catalog library
01:58 PM miss0r: what, you don't keep it within range ?! :]
01:58 PM fragalot: it's literally next to the tv :P
01:58 PM fragalot: can't find anything under 11mm ID
01:59 PM miss0r: Yeah. I found one online :] I'll call my local tool pusher tomorrow, and hear what he has to day
01:59 PM miss0r: say*
01:59 PM gregcnc: how deep was this bore?
02:00 PM miss0r: "only" 22mm
02:01 PM fragalot: that's when you take a solid carbide drill bit & get creative with it :P
02:02 PM miss0r: Sure. I ended up grinding the living bejesus out'a one of thoes brazed chinesium boring bards that came with the boring head
02:02 PM gregcnc: you don't keep any solid carbide types around? https://www.ebay.com/itm/232703387009
02:03 PM miss0r: gregcnc: Not realy. Usualy when I need a special tool, I grind some toolbit steel.
02:03 PM fragalot: miss0r: I have a decent source of miniature solid carbide boring bars..
02:03 PM miss0r: fragalot: The scrapbin behind your workplace?
02:03 PM fragalot: miss0r: no, someone elses'
02:03 PM miss0r: :]
02:03 PM fragalot: new old stock
02:04 PM miss0r: Nice
02:05 PM gregcnc: are these not common over there? I use threading tools like that too.
02:05 PM miss0r: I realy should also get a proper boring for the boring head as well :]
02:06 PM miss0r: gregcnc: It depends on the shop. I don't use'em
02:06 PM gregcnc: sounds like it would have been handy
02:07 PM miss0r: Indeed
02:07 PM gregcnc: I think you'd have to do a lot of boring to come out ahead with an endexable boring bar that small
02:09 PM gregcnc: I did buy a couple 3/16" carbide shank bar off ebay. i've had a small steel shank indexable for ages
02:09 PM miss0r: but that ended up being too loosy goosy ?
02:09 PM gregcnc: it's probably bored over an 1" deep more than once.
02:10 PM gregcnc: I've only done that kind of stuff manually where i can make sure things are going well.
02:12 PM gloops: very cheap for mini lathe
02:12 PM miss0r: If I do decide on using a steel boring bar, i'll make it myself.
02:15 PM gloops: sandvik 50 notes https://www.ebay.co.uk/itm/SANDVIK-MINI-BORING-BAR-E08K-STFCR-06-R-NEW/253506108704?
02:17 PM miss0r: "minimum bore diameter 11mm"
02:18 PM gloops: ahh
02:18 PM gloops: i guess it was either 6 or 8 mm, nice tool though
02:18 PM miss0r: yeah
02:18 PM miss0r: Not too expensive either
02:19 PM fragalot: not yet
02:19 PM fragalot: :P
02:19 PM miss0r: damnit, I didn't see that it was an auction
02:19 PM miss0r: I thought it was just the asking price
02:20 PM fragalot: gloops is sneaky like that
02:21 PM fragalot: posts ebay auctions for really cheap mills, with 6 days remaining
02:21 PM gloops: nobody else will bid on that
02:21 PM gregcnc: I've been looking for carbide bars lately
02:23 PM miss0r: hows that working for'ya ?
02:23 PM miss0r: gloops: get'yer cnc done damnit!
02:24 PM gloops: only bits and bobs left to do haha, ive been busy
02:25 PM miss0r: This is what you said last week ;)
02:26 PM gloops: i wired spindle back up this morning, its all moving now, just a few little things left, no rush ive got plenty of time over next couple of weeks
02:26 PM miss0r: b..but.. THINK OF YOUR AUDIENCE ! :]
02:27 PM gloops: i just hope linuxcnc is up to the job, ive done my bit, what if it cant keep the two motors in sync now???
02:28 PM gloops: i wont have the heart to carry on with it, ill just drag it to the road for the scrap man
02:28 PM miss0r: its up for it ;)
02:29 PM fragalot: it's only as robust as the person that's configured it
02:30 PM gloops: cant be configured any better, the mechanics are sound, the stage is set, the band is ready to play
02:31 PM fragalot: doesn't the band need power?
02:31 PM miss0r: bleh, I was hoping for gun metafor.. Then I would have asked if you curved the bullet.. ect
02:31 PM andypugh: gloops: miss0r Carbide boring bar: https://www.shop-apt.co.uk/sclcr-carbide-shank-boring-bars-for-ccmt-inserts/c08k-sclcr-06-apt-8mm-diameter-carbide-shank-boring-bar-for-ccmt-0602-inserts.html
02:31 PM gloops: the power is at hand, just a few last minute tweaks left
02:32 PM gloops: that reminds me i need to download that usa rocket launch music for the video
02:32 PM miss0r: andypugh: This one is also limited by the minimum ID (11mm) I want to be able to do 6
02:32 PM andypugh: Ah!
02:32 PM andypugh: How deep?
02:33 PM fragalot: miss0r: just means you grind back the toolholder :P
02:34 PM fragalot: i'm wondering now if you can get solid carbide indexable drill bits you could double-use as a boring bar of that size
02:34 PM fragalot: ..back to the tool catalog!
02:34 PM gregcnc: Not in that size
02:35 PM fragalot: sounds like someone should make that then.
02:35 PM gloops: they do theyre $300
02:35 PM gregcnc: pfft
02:35 PM andypugh: What you need (and what I have) is https://www.ebay.co.uk/itm/182662027157
02:36 PM gregcnc: ceratizit ecocut?
02:36 PM gregcnc: I hadn't used the Horn yet
02:36 PM fragalot: andypugh: Agreed, those are nice.
02:36 PM gloops: yes thats another way of doing it
02:36 PM fragalot: miss0r: to be honest, you should be using your EDM anyway xD
02:37 PM andypugh: I use them all the time, great tools. In fact I used one last night to bore a pulley for my servo motor.
02:38 PM gloops: https://www.ebay.co.uk/itm/SOLID-TUNGSTEN-CARBIDE-ROUND-BAR-ROD-4mm-x-91mm-POLISHED-BLANK/282863102550?
02:38 PM miss0r: There are many ways to go about this. I'm just the guy who fell in love with a tool
02:39 PM gloops: but how to tap it for an insert
02:39 PM gregcnc: braze on a steel head
02:39 PM miss0r: with the edm
02:39 PM fragalot: miss0r: no, you're the tool.
02:40 PM miss0r: no, you
02:40 PM andypugh: Seriously, get a Horn holder. eBay is full of the boring / threading / grooving bars. And the smallest can bore 0.8mm
02:40 PM fragalot: >.>
02:41 PM miss0r: I guess that is a reasonable way to go.. also cheaper
02:42 PM fragalot: and more flexible
02:43 PM miss0r: if I wanted flexible I'd attend a yoga class... I WANT RIGID AND CARBIDE
02:44 PM fragalot: yet flexible in terms of boring bar sizes
02:44 PM andypugh: The horn bars are solid carbide. If you use the shortest one that will do the job then almost nothing will be stiffer.
02:45 PM miss0r: andypugh: Now you are just inviting lesser minds, like fragalot, so say something unapropriate
02:53 PM maxlem: Hi looking for any user with a pico system ppmc setup and a pci-express parport
02:54 PM andypugh: maxlem: If you go to the forum or the mailing list you will probably get an answer direct from Jon Elson (who is Pico)
02:54 PM andypugh: But you could try asking your question anyway, while youa re here.
02:55 PM maxlem: I'm in communication with Jon Elson already
02:56 PM maxlem: I want to compare some latency with other users, but thanks!
02:56 PM andypugh: What latency do you have?
02:57 PM maxlem: with the syba card, I get
02:57 PM maxlem: 10 s32 OUT 443336 ppmc.0.read.time 10 s32 OUT 379472 ppmc.0.write.time 8 s32 OUT 826728 servo-thread.time
02:57 PM maxlem: this is a lot
02:58 PM maxlem: on another system with a built-in parport, I get:
02:58 PM maxlem: 10 s32 OUT 280386 ppmc.0.read.time 10 s32 OUT 226323 ppmc.0.write.time 8 s32 OUT 515907 servo-thread.time
02:58 PM maxlem: I expected the pcie card to be an order of magnitude faster
02:59 PM maxlem: Something is not right
03:00 PM andypugh: I wouldn’t expect the bottleneck to be the PC Bus, more the parallel port link.
03:01 PM andypugh: But you are actually talking about thread time not latency, I think?
03:02 PM maxlem: yes
03:02 PM maxlem: I'd like to push the update rate further
03:03 PM maxlem: the servo loop is 98% read/write operations to the ppmc card
03:05 PM andypugh: Yes, I think it is taking to long in _both_ cases.
03:06 PM andypugh: But I don’t know enough about PPMC to know if there is any adjustment available.
03:07 PM CaptHindsight: take this one step up to a climbing mill http://www.3ders.org/articles/20180319-koala-incredible-3d-printer-climbs-its-printed-structures-for-unlimited-z-axis-building.html
03:08 PM andypugh: Cute, but pointless.
03:09 PM andypugh: Right, I need to get back to this servo wiring
03:09 PM andypugh: AFK
03:11 PM fragalot: CaptHindsight: I wasn't aware koalas used rack & pinions to climb trees?
03:14 PM gloops: i dont think evolution ever arrived at a rack and pinion
03:14 PM gloops: which should tell you something
03:17 PM gloops: some one eyed deep sea micro mollusc might prove me wrong though
03:17 PM gregcnc: the conveyor types linked are actually interesting are they out in the wild?
03:18 PM fragalot: gloops: https://www.extremetech.com/extreme/166493-evolution-delivers-the-first-mechanical-gear-found-in-a-living-creature
03:18 PM fragalot: close, but not quite a rack yet
03:18 PM gloops: roller rack gregcnc?
03:18 PM gregcnc: https://www.3ders.org/articles/20170509-blackbelt-3d-unveils-conveyor-belt-3d-printer-for-continuous-fdm-printing.html
03:20 PM gloops: surprised that hasnt been thought up before now
03:20 PM fragalot: i wonder how it manages to print overhangs?
03:23 PM CaptHindsight: fragalot: it prints those upside down, so they underhang
03:23 PM fragalot: CaptHindsight: ....still?
03:24 PM CaptHindsight: they never have actual pictures of how it's done, it's magic
03:26 PM XXCoder: capt reminds me of that cnc router project. similiar concept
03:27 PM XXCoder: its pretty small machine, bit over 4 feet long, 2 feet wide, but can cut whatever strip length
03:27 PM CaptHindsight: https://youtu.be/DOlN6FtCX6g?t=5m23s
03:28 PM XXCoder: they call that extreme?
03:28 PM XXCoder: I saw one where guy did 400mm long bridges witg petgb
03:28 PM CaptHindsight: fragalot: ^^ accurate to within a few mm
03:29 PM fragalot: that must be an older controller
03:29 PM fragalot: or slicer, anyway
03:29 PM CaptHindsight: Sep 18, 2013
03:29 PM fragalot: I think slic3r introduced proper "bridging" quite a long time ago
03:29 PM fragalot: works well
03:30 PM fragalot: iirc I've done bridges about 12cm long on mine before with /reasonable/ success
03:31 PM CaptHindsight: https://www.youtube.com/watch?v=qnEgSlP3F2Q Upside down 3d Printing overhang with temporary support technology
03:31 PM fragalot: I bet that gives you amazing spaghetti if you leave that on overnight
03:31 PM fragalot: interesting take on it though :P
03:32 PM XXCoder: very interesting
03:49 PM CaptHindsight: has anyone combined an inkjet or micronozzles yet with FDM to add color as it prints?
03:49 PM fragalot: not with FDM afaik
03:50 PM XXCoder: theres filiment slicer and fuser that does essentally same thing
03:50 PM fragalot: or mixing nozzles, but it's far from the same thing
03:50 PM XXCoder: http://www.sublimelayers.com/2017/06/mosaic-palette-journey-begins.html
03:50 PM fragalot: you inevitably get colors blending an dmixing
03:51 PM fragalot: where-as with putting color on separately you have full control
03:55 PM XXCoder: http://www.sublimelayers.com/search/label/Mosaic%20Palette?&max-results=8
03:56 PM XXCoder: seems to work well

04:44 PM * fragalot wants one too
04:44 PM Tom_L: you got a shars?
04:44 PM Tom_L: i think the hex is smaller than on a kurt
04:44 PM fragalot: a big Vertex one.
04:45 PM Tom_L: gotta turn a handle for it next
04:45 PM fragalot: vertex VA-6
04:45 PM Tom_L: chamfer is a little deeper than i wanted but it's ok
04:46 PM Tom_L: new tool, never tested :)
04:46 PM fragalot: certainly LOOKS functional :D
04:46 PM Tom_L: yup
04:48 PM fragalot: ha
04:48 PM fragalot: email forwarded from the gun club with one of the schedules
04:49 PM fragalot: original mail said "so when the hell am I going to get the damn login details to put these up on the website myself?"
04:49 PM fragalot: so professional :-)
04:49 PM Tom_L: heh
04:49 PM fragalot: hooray! my epoxy shipped
04:50 PM Tom_L: you'll be building soon
04:50 PM fragalot: nah, still need a lot of parts before I can start that
04:50 PM fragalot: but I can start experimenting
04:51 PM Tom_L: i'm just happy i can finally cut parts. that sherline was a piece of crap
04:51 PM gloops: thats a success Tom if you beat a shop made machine with a home build
04:52 PM Tom_L: still need a bigger spindle motor
04:52 PM gloops: 3kw?
04:53 PM Tom_L: i doubt i need one that big
04:53 PM fragalot: no same power, just bigger
04:53 PM fragalot: :D
04:53 PM Tom_L: this thing is maybe .6hp at bes
04:53 PM Tom_L: t
04:53 PM Tom_L: whatever sherline puts on their junk
04:53 PM Tom_L: but the spindle works good
04:53 PM fragalot: my rf45 is a 2.2kW, and i've never managed to stall it out so far
04:54 PM gloops: ahh ots the sherline spindle yes
04:54 PM fragalot: long live gears. :P
04:54 PM Tom_L: i'm gettin that chinaco power meter to put on it
04:54 PM Tom_L: belt drive
04:54 PM Tom_L: i changed that while it was still on the sherline
04:54 PM gloops: 2.2 with vfd is abput £240 i think
04:55 PM gloops: no real cheap way round it i dont think, some in the diy-cnc group have been playing with different motors to do it
04:55 PM Tom_L: i wonder if a servo would work
04:55 PM Tom_L: aren't they basically the same thing?
04:56 PM gregcnc: of course it would
04:56 PM gregcnc: just get one rated for the RPM you need
04:56 PM Tom_L: that's what sprockets are for :)
04:56 PM gloops: but what bearings?
04:56 PM Tom_L: i think this is 1.7:1
04:56 PM Tom_L: i dunno
04:57 PM gregcnc: industry did away with gearing for the most part
04:57 PM Tom_L: i got a bunch of holders for this thing, i kinda hate to not use them
04:57 PM Loetmichel: Tom_L: sprockets are discontinous motion, you know that?
04:57 PM Loetmichel: (and loud)
04:57 PM Tom_L: belt
04:57 PM gloops: or make a spindle shaft and drive it with a big motor and pulleys for speed change or something
04:58 PM gregcnc: bah
04:58 PM Tom_L: from that: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/old_pulley2.jpg
04:58 PM Tom_L: to that: http://tom-itx.no-ip.biz:81/~webpage/cnc/new_pulleys/new_pulley_mounted2.jpg
04:59 PM gregcnc: Is the GT3 quiet?
04:59 PM Tom_L: yeah
04:59 PM gregcnc: my emco howls over 4500
04:59 PM Tom_L: the air nozzle makes more noise than the mill
04:59 PM Tom_L: other than cutter noise
05:00 PM Tom_L: i think i can get about 5k rpm out of this but i don't go ove 4k usually
05:01 PM gregcnc: Emco has MXL
05:02 PM Tom_L: i don't remember what i put on the Z axis stepper
05:02 PM Tom_L: XL i think
06:28 PM ferdna: so i got them...
06:28 PM ferdna: https://www.dropbox.com/s/qvuwbvl59tgie4z/20180321_171455.jpg?dl=0
06:30 PM ferdna: Tom_L, ^
06:31 PM Tom_L: that was quick
06:31 PM Tom_L: i want a gecko :(
06:32 PM Tom_L: did they tell you what resistors they sent?
06:32 PM ferdna: Tom_L, if you want it you can have it... i'll send it to you...
06:32 PM Tom_L: depending on your steppers you may need to change those
06:32 PM Tom_L: naw
06:32 PM ferdna: no idea
06:33 PM ferdna: they look more like fuses to me
06:33 PM Tom_L: you need an idea before you use them
06:33 PM Tom_L: they're current limit resistors
06:33 PM Tom_L: it will tell you where to put them
06:33 PM ferdna: oohhh
06:34 PM Tom_L: 2 of the screw terminals
06:34 PM ferdna: no instructions in the box
06:34 PM Tom_L: you can get the pdf off their site
06:34 PM ferdna: 5a 1E
07:23 PM FAalbers: Home bound I go !
08:43 PM hazzy-dev: Anybody own or have experience with an AH Bugeyed Sprite? (aka Crabeyed Sprite to those across the pond?)
09:17 PM CaptHindsight: the car or the crustacean?
09:29 PM Tom_L: i've worked on them before
09:30 PM Tom_L: been quite a while
09:30 PM Tom_L: what about it?
09:40 PM hazzy-dev: CaptHindsight: The car, but it is not much different from the crustacean, especially with regard to size!
09:41 PM hazzy-dev: Tom_L: I am trying to retrofit a anti sway bar, but can't find a good place to mount the bushings to the chassis so was wondering if anybody had done that before
09:41 PM Tom_L: wasn't there one the hood folded forward on?
09:41 PM Tom_L: i'm trying to remember...
09:41 PM Tom_L: i doubt i'd be much help there
09:42 PM Tom_L: they definitely need something though :D
09:42 PM hazzy-dev: I seem to remember some having the hood go forward too, but on this one it goes back
09:43 PM hazzy-dev: I just take the hood off, since even with it up I get get my head under it :D
09:44 PM hazzy-dev: can't get, even
09:44 PM Tom_L: it was awkward to work on for sure
09:45 PM hazzy-dev: I am worried there won't be enough ground clearance once I get the sway bar on
09:45 PM hazzy-dev: xD
09:51 PM CaptHindsight: hazzy-dev: they handle about the same
09:51 PM CaptHindsight: hazzy-dev: front or rear sway bar?
09:53 PM CaptHindsight: rear https://d3dxp4akn1otfb.cloudfront.net/1961-Austin-Healey-Sprite-Import%20Classics--Car-100895957-d6c255343c5d6dd96bfa5932525269c3.jpg?w=1280&h=720&r=thumbnail&s=1
09:53 PM Tom_L: what was the larger version called?
09:53 PM Tom_L: i can't remember now
09:53 PM hazzy-dev: CaptHindsight: Front
09:53 PM CaptHindsight: front https://dy98q4zwk7hnp.cloudfront.net/1961-Austin-Healey-Sprite-Import%20Classics--Car-100895957-a48084236aab445df6d4d47e74bcca05.jpg?w=1280&h=720&r=thumbnail&s=1
09:54 PM CaptHindsight: hazzy-dev: you have those two frame rails
09:54 PM Tom_L: was the larger one the MKIII?
09:54 PM Tom_L: if you can call any of em large...
09:55 PM Tom_L: http://www.realmusclecar.com/listings/1967-austin-healey-3000-mkiii-bj8/
09:55 PM Tom_L: that's what comes to mind when i think of that one
09:55 PM CaptHindsight: heh the exhaust looks like it has a drip loop
09:56 PM hazzy-dev: CaptHindsight: Yes is does have the frame rails. In that last pic it looks like they drilled and taped little welded on pads for mounting the sway bar bushings?
09:57 PM hazzy-dev: Yeah, that loop in the exhaust is funny, it tends to hit on stuff ...
09:58 PM CaptHindsight: hazzy-dev: what year?
09:58 PM hazzy-dev: 58
09:58 PM hazzy-dev: First year they were made
09:58 PM CaptHindsight: ^^61
09:58 PM Tom_L: complete rust bucket?
09:59 PM hazzy-dev: Tom_L: Not anymore!
09:59 PM Tom_L: which of those old cars had positive gnd?
09:59 PM Tom_L: i know some of the MG's did
09:59 PM Tom_L: oh and generators...
09:59 PM hazzy-dev: Many of them did
10:00 PM hazzy-dev: This one had pos earth and still has a gen
10:00 PM hazzy-dev: Converted to neg earth
10:00 PM Tom_L: SU carbs?
10:00 PM hazzy-dev: yes
10:00 PM Tom_L: heh
10:00 PM Tom_L: leaks?
10:00 PM Tom_L: they all did...
10:00 PM hazzy-dev: Leaks, which ones?
10:00 PM hazzy-dev: :D
10:01 PM CaptHindsight: https://www.speedwellengineering.com/wp-content/uploads/2011/01/spanglertubpainted1.jpg
10:01 PM Tom_L: holy crap that's bright
10:02 PM CaptHindsight: heh, you could powder coat that thing
10:02 PM hazzy-dev: haha! that might be dangerous, blind othe rdrivers!
10:02 PM hazzy-dev: Here she is: https://i.imgur.com/PFRK0IM.jpg
10:04 PM hazzy-dev: No more rust!!!! https://i.imgur.com/ZkbAjFe.jpg
10:04 PM CaptHindsight: were they rack and pinion?
10:07 PM hazzy-dev: I think it is a worm, but can't remember :o
10:07 PM Tom_L: i can't either
10:08 PM Tom_L: what's the red one beside it?
10:09 PM Tom_L: looks like it's got knockoff wheels
10:09 PM hazzy-dev: It does! It is a 1926 AC
10:09 PM Tom_L: i've had those come off
10:11 PM hazzy-dev: Sorry, I meant to 1936 AC
10:11 PM hazzy-dev: https://i.imgur.com/kjN421n.jpg
10:12 PM Tom_L: so then on to the next question... what's the one next to it :D
10:12 PM Tom_L: fairly new..
10:13 PM CaptHindsight: I used to like working on cars years ago
10:13 PM hazzy-dev: It is a 2003 handa civic, I think
10:13 PM Tom_L: CaptHindsight, i got over it
10:14 PM CaptHindsight: I still work on them but now i don't like it
10:14 PM Tom_L: i keep mine going and that's about it
10:14 PM CaptHindsight: I started on a simple paint job and now it's almost a complete strip down and rebuild
10:15 PM CaptHindsight: my son hates me
10:17 PM hazzy-dev: These aren't my cars, they belong to a elderly neighbor and she is doing most of the work since her husband died, I am just helping out with the things she can't do.
10:17 PM Tom_L: i see
10:17 PM hazzy-dev: My cars are much less interesting, but my sister just wrecked one of them so they need work too Oo
10:17 PM Tom_L: my opinion of you has changed a little bit :D
10:17 PM hazzy-dev: Good, so now you think I am less crazy, right?
10:18 PM hazzy-dev: :)
10:18 PM Tom_L: heh
10:18 PM Tom_L: the one's i worked on weren't mine either
10:18 PM Tom_L: and the ones that owned them didn't
10:19 PM CaptHindsight: https://i.pinimg.com/originals/a7/0d/18/a70d189c82df71af9077ee5cbe918ed1.jpg
10:19 PM CaptHindsight: http://www.britishracecar.com/NickChamberlain-Healey-Sprite/NickChamberlain-AH-Sprite-CC.jpg
10:20 PM hazzy-dev: Aha! Thank you CaptHindsight! Those are very helpful
10:20 PM hazzy-dev: So I need to weld on some little pads it looks like
10:21 PM hazzy-dev: And the end of the sway bar goes UP, I had it going down which made the ground clearance very low
10:22 PM CaptHindsight: http://valvechatter.us/?p=3365
10:29 PM hazzy-dev: Thank you for your help CaptHindsight
10:29 PM hazzy-dev: Your Google skills must be much better than mine, I searched for nearly 2hr today on and off and came up with zilch that was helpful
10:29 PM CaptHindsight: https://imagebin.ca/v/3vi1R8v2AVgh remove rear suspension, media blast and derust (electrolysis), machine new bushings and paint
10:30 PM CaptHindsight: hazzy-dev: you must work on your google-fu grasshopper
10:33 PM CaptHindsight: new everything, bearings, springs, bushings, rotors, calipers etc
10:33 PM CaptHindsight: same for the front
10:33 PM hazzy-dev: Looks sharp! What is that on?
10:33 PM CaptHindsight: brand new fenders on ebay for $30ea
10:35 PM CaptHindsight: 01 Maxima https://imagebin.ca/v/3vi3fSIe3kyT
10:36 PM hazzy-dev: Aha
10:37 PM CaptHindsight: nothing special
10:37 PM CaptHindsight: but parts are cheap
10:38 PM CaptHindsight: i think the whole suspension as a kit was <$400
10:38 PM hazzy-dev: I just got basically a whole new front end for a 02 corolla on ebay (bumber, hood, fenders, light ..) for less than 300, I was expecting it to be 1200. I was very impressed with what is available these days
10:38 PM Tom_L: wax on... wax off...
10:38 PM CaptHindsight: yeah
10:39 PM CaptHindsight: I called a bone yard in Phoenix and had them cut me the wheel arches
10:39 PM CaptHindsight: $50
10:39 PM CaptHindsight: new rockers were $25ea
10:39 PM hazzy-dev: Not bad at all
10:39 PM CaptHindsight: complete leather interior $100 with door panels
10:40 PM hazzy-dev: I tried a couple junk lots for parts for the corolla but all the cars already had what I needed striped, or had also been in a wreck
10:40 PM CaptHindsight: now you can't park it just anywhere
10:42 PM hazzy-dev: Haha, the leather will be nice
10:42 PM hazzy-dev: I am happy when one of my cars gets an upgrade from vinyl to cloth :)
10:43 PM CaptHindsight: looking for a fancy driver seat
10:43 PM CaptHindsight: maybe something from a BMW with all the adjustments and heat
10:44 PM CaptHindsight: is there anything out there that detects blaring sport light from the car behind you and redirects it back into the vehicle behind you?
10:44 PM CaptHindsight: sport/spot
10:44 PM CaptHindsight: maybe a mirror on a gimbal :)
10:45 PM hazzy-dev: What I want down here in the south is a peltier COOLED seat
10:45 PM hazzy-dev: LOL, that would be great!
10:45 PM CaptHindsight: I swear some people love to tailgate with their HID light son
10:46 PM hazzy-dev: How bought just chroming your entire car? That might work
10:46 PM Wolf__: 2 reason I love my big ass truck
10:46 PM hazzy-dev: http://www.caswellplating.com/electroplating-anodizing/spray-on-chrome-kits/spray-on-chroming-system-50-square-feet.html
10:46 PM Wolf__: tailgaters headlight shine under it
10:47 PM Wolf__: and cooled forced air in the seats
10:47 PM CaptHindsight: unfortunately not legal here to have a chrome/mirror car
10:47 PM Tom_L: get an led strip and aim it rearward
10:48 PM CaptHindsight: been tempted
10:48 PM CaptHindsight: with a warning sign first
10:49 PM Tom_L: https://reactual.com/outdoor-equipment-2/led-lights/brightest-led-lights.html
10:49 PM CaptHindsight: seems they also frown on releasing an oil slick, grenades, pointy tire poking devices etc etc
10:50 PM Wolf__: salt spreader works well on tailgaters
10:50 PM CaptHindsight: filled with gravel?
10:50 PM Tom_L: just drop a bucket of BB's
10:51 PM CaptHindsight: hhmmm
10:52 PM CaptHindsight: rear facing washer pump nozzle filled with oil
10:52 PM CaptHindsight: or paint remover
10:52 PM Tom_L: that was my next thougt but you beat me to it
10:53 PM CaptHindsight: skunk fluid
10:53 PM Tom_L: follow them home and leave messages in their yard with weed killer
10:53 PM CaptHindsight: too stalkery
10:54 PM Tom_L: or just pop the trunk to the sight of a gattling gun mounted inside
10:55 PM CaptHindsight: hot tar
10:56 PM Wolf__: rear aimed air cannon with glass marbles for ammo
10:58 PM hazzy-dev: A paint ball gun would probably work well, even though it would be non destructive
11:01 PM CaptHindsight: most of the time I just wave in the rear view mirror and they go around me
11:03 PM CaptHindsight: flamethrower in 5, 4, 3,, 2.....
11:03 PM CaptHindsight: Wolf__: not a problem high off the ground in a truck
11:04 PM CaptHindsight: but really annoying when in a low car
11:04 PM Wolf__: yeah
11:04 PM * Tom_L checks out for the night
11:04 PM Wolf__: makes me wish I had done 5% tint on the rear window of my wagon
11:06 PM CaptHindsight: some towns around here ticket for tint
11:06 PM CaptHindsight: others could care less
11:07 PM Wolf__: only windows not legal on my car are the front side windows at 20%, 35% is legal limit, rear of wagon/van/suv can be blacked out
11:08 PM CaptHindsight: going to try hanging some >90% reflective film in the rear
11:11 PM Wolf__: front sides and rear are 20%, 5% on the rear sides on mine, kinda dark https://i.imgur.com/28eeGh0.jpg
11:12 PM CaptHindsight: looks good
11:12 PM Wolf__: without the tint I felt like I was driving a fishbowl
11:13 PM CaptHindsight: is the paint a blue metallic?
11:13 PM Wolf__: grey
11:13 PM CaptHindsight: blue grey
11:15 PM Wolf__: platinum grey metallic, my last 5 cars were black I was fed up with trying to keep a black car looking good lol
11:15 PM CaptHindsight: I only wash them once a year
11:15 PM CaptHindsight: if they need it or not
11:16 PM CaptHindsight: black is actually a tough one
11:17 PM Wolf__: about the same, but every time I look at my truck I want to detail it lol, but that is such a bitch https://i.imgur.com/e4EqRjF.jpg
11:17 PM CaptHindsight: even slightly different whites don't show it as much
11:18 PM Wolf__: at least the grey can be dirty and not show from 10 feet lol
11:23 PM r0n0x: is it ok to discuss normal cnc stuff here?
11:23 PM Wolf__: I hope so
11:24 PM Wolf__: seeing topic has been motorcycles and cars for the last hour or two
11:24 PM r0n0x: i wanna get a co2 laser to screw around with but eventually make into a laser cutter
11:24 PM r0n0x: 40W i can probably get no problem, wondering if it can be used for my purposes
11:25 PM r0n0x: being cutting MDF and acrylic
11:25 PM Wolf__: what are you thinking of cutting
11:25 PM Wolf__: how thick
11:25 PM r0n0x: 4-5mm, maybe 6mm though it wouldnt have to be clean at 6
11:25 PM r0n0x: mostly though 3mm
11:26 PM Wolf__: 40w (actual) should do that
11:26 PM r0n0x: :O
11:27 PM * r0n0x is shocked
11:27 PM r0n0x: my main use is like boxes, cases, and electrical mounts
11:27 PM r0n0x: occasionally though also stuff that needs to go under load of sorts
11:28 PM r0n0x: i cant think of anything off the top of my head right now though
11:29 PM hazzy-dev: Nice looking truck Wolf__
11:29 PM Wolf__: its a beast
11:30 PM Wolf__: I need to redo the hydraulic system on it tho
11:31 PM CaptHindsight: r0n0x: another option for the laser is a SLS printer
11:31 PM r0n0x: SLS?
11:33 PM CaptHindsight: https://youtu.be/165Ql-T09SE?t=25s
11:33 PM CaptHindsight: Selective Laser Sintering
11:33 PM r0n0x: ah
11:34 PM r0n0x: cool
11:35 PM CaptHindsight: https://ibin.co/w800/3i0LDN2s3TZ7.jpg this one uses a 30W CO2 RF laser and galvo scanner
11:36 PM hazzy-dev: Finally finished revamping the tool-table for hazzy: https://i.imgur.com/fPHRZkG.png
11:36 PM hazzy-dev: gn8
11:37 PM CaptHindsight: hazzy-dev: is it ready for test drives yet?
11:38 PM CaptHindsight: r0n0x: people use Chinese glass laser tubes for laser cutters/markers all the time
11:38 PM CaptHindsight: lots of examples using LCNC on the forums
11:39 PM CaptHindsight: it's also known to have burned down someones house :)
11:40 PM hazzy-dev: CaptHindsight: No not quite, but I merged the GTK3 branch to master yesterday, so it is easier for people to try it if they want. Getting close to prime time I hope :)
11:40 PM CaptHindsight: r0n0x: https://www.slideshare.net/AlastairDSilva/linuxcnc-for-fun-profit
11:41 PM CaptHindsight: https://www.youtube.com/watch?v=U3kADpXyDE8 Controlling a K40 Chinese Laser with LinuxCNC
11:44 PM r0n0x: ooh
11:44 PM r0n0x: just to clarify though, 4mm mdf and plastic is easy done with 40W right?
11:46 PM Wolf__: I would go bigger, but I tend to overdo things lol
11:46 PM CaptHindsight: http://am.co.za/laser/thickness here's a general overall guide
11:47 PM r0n0x: 80W tube and PSU is way too expensive and my needs dont really warrant that expense yet
11:48 PM r0n0x: i mean, i could easily acheive the same result with a router
11:49 PM CaptHindsight: https://sc02.alicdn.com/kf/HTB1oF7jQXXXXXbXaXXX760XFXXXc/1902110/HTB1oF7jQXXXXXbXaXXX760XFXXXc.png
11:50 PM CaptHindsight: r0n0x: what price did you get for a 40w tube?
11:50 PM r0n0x: hmm, if i can do 8mm acrylic with 50W then screw mdf XD
11:50 PM r0n0x: i think like $250 total with psu
11:51 PM r0n0x: $200aud
11:54 PM r0n0x: hmm, seems for $270 i can do 50W tho
11:54 PM CaptHindsight: beware of Chinese watts
11:55 PM CaptHindsight: also sellers that mark a 30W tube as 50w
11:55 PM CaptHindsight: and how do you deal with problems?
11:55 PM CaptHindsight: tube shows up cracked, something missing from the power supply etc etc
11:58 PM r0n0x: im good at dealing on aliexpress
11:58 PM r0n0x: damn, 60W costs more in shipping than the tube itself
11:58 PM r0n0x: but 50W seems attainable
11:59 PM r0n0x: for not much more than 40W
11:59 PM r0n0x: maybe the same if this seller will combine postage
