01:51 AM XXCoder: none oif that math coprocessor crap lol
01:51 AM Crom: pops wouldn't go for the Appel III
01:52 AM Crom: I had 386sx-16's then sx-33's then sx-40's then I got a AMD 40586-133, then I got a Pentium P60
01:53 AM Crom: I had to buy the Trash-80s with my own money
01:54 AM Crom: I got a 386DX-25 motherboard than didn't like running at 25mhz... ran fine at 12.5mhz all socketed DIP's
01:54 AM archivist: kidz...

02:03 AM Crom: 100mm spindle
02:03 AM Crom: oops wrong computer
02:03 AM dean: i dont know but anyone build there own plasma cutter yet
02:03 AM XXCoder: dean its really not that hard
02:04 AM XXCoder: its basically cnc router
02:04 AM XXCoder: just water bed and plasma cutter for tool
02:05 AM Crom: easier to buy a cutter.... table is pretty easy to build.. but yeah most people just buy the table
02:05 AM dean: yea i have a small hobart plasma cutter i wanted to hook up and once i get my shop moved and put up change to a bigger plasma cutter
02:06 AM dean: I live in Chevak Alaska and would like to make as much stuff as I can
02:06 AM Crom: I'm thinking when I make a plasma table I'll use #25 chain for drive.
02:06 AM dean: shipping is a killer out here so if I can reuse or make it myself saves me a lot
02:07 AM archivist_herron: a number of plasma cutters are linuxcnc driven
02:07 AM Crom: where you at?
02:07 AM dean: me Chevak Alaska
02:07 AM Crom: I in southwest corner of Riverside county in California
02:07 AM Crom: yeah AK is not cheap for shipping...
02:08 AM dean: not cheap for living either haha
02:08 AM Crom: LA for me is hour to 2 hours depending on where in town I have to go
02:08 AM dean: i pay 6.25 a gallon of gas
02:08 AM XXCoder: $2.65 or so here
02:09 AM XXCoder: usually above national average
02:09 AM Crom: don't you have a refinery up there?
02:09 AM Crom: $3.09 last fill up here
02:09 AM Crom: $2.89 3 weeks ago
02:10 AM dean: theres nothing next to us Alaska is 1/3 size total lower 48 states we have refinery but no where close to us
02:10 AM Crom: $2.65 in Salinas a month ago...
02:11 AM dean: well i have to go my old ladies home
02:11 AM Crom: well time for bed nite nite all
02:13 AM XXCoder: laters
04:17 AM The_Ball: I have an old contraves spindle dc servo drive, does anyone know what "bridge select" 1 or 2 means? I can see in the schematics that it's selecting two different output stages, but what is it used for?
04:19 AM IchGucksLive: hi
04:19 AM IchGucksLive: dean still on
04:20 AM IchGucksLive: The_Ball: its for gearing
04:21 AM IchGucksLive: most like Maho uses 2 gear stages for the spindles
04:21 AM IchGucksLive: lcnc got a comp for that behavier
04:21 AM The_Ball: There are two gears in the spindle, yes
04:21 AM IchGucksLive: as it dicides the gear stage to use on RPM calles
04:23 AM IchGucksLive: im off to classroom just a quick breef here
04:23 AM IchGucksLive: till later
05:34 AM gcardinal: Is there a more affordable alternative to Greenlee D-SUB punches? like this one http://www.greenlee.com/products/PUNCH-UNIT%2540dCONNECTOR-9-PIN-(229).html?product_id=15349
05:34 AM gcardinal: Or what is best way to make holes for d-sub ports in an electrical enclosure ?
05:37 AM gcardinal: My initial plan was cut a bigger rectangular hole and place a milled aluminium plate over it with proper milled holes - but what be much nicer to do it directly in enclosure
05:39 AM malcom2073: gcardinal: Knee mills are good for getting large enclosures mounted for that :-D.
05:39 AM malcom2073: You could also make your own punch, they're not terribly hard to make
05:40 AM malcom2073: course, making your own you'll likely quickly get over the cost of buying one in terms of time and effort heh
05:41 AM gcardinal: yeah... its almost strange there is no more affordable alternatives. dont have access to a bigger mill and the one I have can't handle even door of the enclosure (no way to secure it for milling)
05:44 AM archivist_herron: can be cheaper to use a local sheet metal company to press stuff
05:44 AM enleth: gcardinal: a set of generic round punches for "corners" and a cold chisel for straight lines
05:45 AM enleth: gcardinal: you could mill a die and affix it somehow on the other side of the panel, then punch/chisel away
05:47 AM enleth: making just the die, without a matching punch, should be way easier than doing both
05:49 AM enleth: put a threaded hole in the middle, drill a hole in the panel where the final hole is supposed to be, smack some superglue on the die, bolt it in place until the glue sets, then set the whole thing on a hard surface, die facing down, and punch away
05:49 AM enleth: that's what I'd do, should work
05:54 AM * archivist_herron grimaces
05:59 AM jthornton: morning
06:00 AM gcardinal: Thanks for answers and ideas. I think I would get better finish if I cut part of it and mill out a alu insert
06:00 AM gcardinal: Was just a bit strange not to see any other alternatives to greenlee...
06:03 AM jthornton: you could mill the D-SUB hole... ngcgui has a ready made thing for that
06:05 AM jthornton: or use the Roy Underhill method
06:23 AM * jthornton has to finish the chicken tractor this week and get the coop built
06:36 AM jthornton: http://media.blog.homedepot.com/wp-content/uploads/Chicken-Coop-Plans-TheCreativeMom.pdf
07:10 AM nallar is now known as Ross
08:23 AM TurBoss: Hi
08:31 AM TurBoss: i'm back
10:02 AM IchGucksLive: hi from a sunny not that cold germany
10:33 AM IchGucksLive: till later
10:47 AM roycroft: yay!
10:47 AM roycroft: more vacation days!
10:48 AM * roycroft will get his shop and yard projects caught up
11:25 AM Crom: then come do mine?
11:27 AM Crom: dang it.. didn't make my mount wide enough.. need 13mm more width for the 100mm mount
11:27 AM jdh: un-cut it.
11:27 AM Crom: gotta find a welder to welder on the off cuts
11:28 AM Crom: s2/welder/weld/
11:41 AM Crom: looking at a ER25 air cooled spindle
11:42 AM Crom: $731 with VFD
11:42 AM Crom: $2100 with VFD and BT30 ATC
11:55 AM jdh: atc would rock
12:04 PM XXCoder: "a tool changer"? heh
12:06 PM sync_: automatic toolchanger
12:06 PM XXCoder: lol funny how short work out
12:22 PM IchGucksLive: hi
12:24 PM XXCoder: hey
12:24 PM IchGucksLive: there are selfmade ATC for Kress Spindles out
12:24 PM IchGucksLive: sk20 i think
12:30 PM Loetmichel_: IchGucksLive: what i never get: why go thru the hassle of making an ATC just to introduce vibrations and wobble and noise with a kress as the drive motor for it?
12:31 PM IchGucksLive: its cheep
12:31 PM Loetmichel_: not with the atc attached
12:32 PM jdh: because atc is cool
12:32 PM Crom: atc lets you use a tool changer...
12:32 PM Loetmichel_: yes it is
12:32 PM Crom: atc lets you have premounted tools already in your tool table
12:32 PM Loetmichel_: thats whay i dont get why make a good tool and then throw out all that precision by usung a sub-par drive motor on it?
12:33 PM Loetmichel_: using
12:33 PM Crom: cuz it's what you can afford?
12:34 PM Loetmichel_: if you can afford a tool changer for (mor than )a few 100 bucks you can also afford a chnese 1.5kw spindle or something similar
12:34 PM Crom: my boring bar won't ork... I need to get a smaller one
12:34 PM Loetmichel_: its not THAT much more expensive than a Kress, but MUCH less vibration and more power
12:35 PM jdh: my chines spindle is pretty smooth
12:35 PM Loetmichel_: jdh: thats what i meant
12:36 PM Loetmichel_: a kress is loud, has brushes that need changing, isnt meant to do 24/7, and has more runout and less balancing done to it
12:36 PM Loetmichel_: and it only costs about 100 bucks less than a chinese spinle with 1.5 times the power and all the other plis sides
12:36 PM Loetmichel_: plus
12:42 PM Loetmichel: hihi, boss called from .dk. he arrived safely and in time at the customer. just did lunch with him. customer said: from the 6 other bidders on that contract only one called in that he will be there a bit later the day. the other 5 only said "not enough time, cant be done to the deadline"... so it was worth the effort to do long hours on saturday and sunday... 1/2 is waaaay better chances than
12:42 PM Loetmichel: 1/7 ;)
12:51 PM IchGucksLive: michel ask him for some dutyx freee
12:51 PM IchGucksLive: Loetmichel: girls day ahead are you doing somthing
12:52 PM Crom: still looknig at this one http://www.ebay.com/itm/New-3KW-ATC-Automatic-Tool-Change-Water-Cooled-Spindle-Motor-BT30-3-7KW-380V-VFD-/272638506232
12:52 PM CaptHindsight: http://www.27bslash6.com/interviews.html
12:52 PM sync_: pls, it is the future day
12:52 PM IchGucksLive: Crom: goes PRO
12:52 PM sync_: as we are not discriminating boys
12:53 PM IchGucksLive: sync_: to ring in more female to boy jobs
12:53 PM IchGucksLive: 5400 male studends on mashining and 8 female
12:53 PM IchGucksLive: sync_: lots of headspace to go
12:54 PM IchGucksLive: sync_: as special the US concern TEREX crane wants to make more female cranes as the driver are non male
12:55 PM IchGucksLive: and ofcause JohnDeer
12:56 PM IchGucksLive: https://www.deere.de/de_DE/our_company/about_us/john_deere_deutschland/jd_deutschland.page
12:56 PM FinboySlick: CaptHindsight: Thanks for reminding me of that wonderful site ;)
12:57 PM IchGucksLive: http://www.terex.com/cranes/de/aboutus/locationinformation/Germany/Zweibruecken/index.htm
12:57 PM IchGucksLive: on the last link you can see the Uni on top of the hill
12:57 PM IchGucksLive: right to the forest
12:59 PM IchGucksLive: Folks give me a ideeo n why the cranemanufacture devides in US-Tonnes and World tons
12:59 PM IchGucksLive: lift range
12:59 PM IchGucksLive: is there a different in Tonns
12:59 PM IchGucksLive: never heard on that
01:00 PM IchGucksLive: m/ft ok kg/lb ok but T/to
01:00 PM Crom: us long ton 2200#'s real close to metric ton, short tone 2000#'s under a metric tone
01:01 PM IchGucksLive: thanks
01:01 PM IchGucksLive: i will put this issue on the list to teatch
01:01 PM IchGucksLive: as it can make life changing
01:02 PM FinboySlick: Crom: The lower RPM in that spindle's range is a bit limiting.
01:04 PM IchGucksLive: im off for gardening and early sleep as we got firer alarm last night and i got less sleep on my age it is not the highlight
01:04 PM IchGucksLive: Gn8
01:30 PM roycroft: why do some folks prefer running their lathe spindle in referse and parting off from the rear?
01:30 PM roycroft: reverse
01:31 PM Crom: no idea... I can't do that unless i want to unscrew my chuck
01:33 PM sync_: roycroft: because it prevents chatter
01:33 PM roycroft: it seems to be somewhat commonly done
01:33 PM roycroft: how so, sync_?
01:34 PM sync_: due to the geometry, probably
01:34 PM sync_: I don't really know why that is, I tried to draw it out in cad but failed
01:34 PM sync_: but it is the case
01:35 PM roycroft: the only real difference i can see is that the cutting edg of the parting tool would be closer to the center of the cross slide when parting off from the rear
01:40 PM Crom: I just make sure my grind is a bit longer on the part off side... so the part usually parts clean, and I can continue going in and clean up the held stock
02:48 PM CaptHindsight: I weld my spindles on so that they never come loose
03:13 PM Crom: now to wait for money to come in. :(
03:13 PM Crom: |/
04:32 PM Deejay: gn8
05:10 PM Crom: received my VA claims file, it's missing all the service medical records GRRRRR
05:14 PM Crom: and place I need to call closed 45 minutes ago
05:40 PM Crom: THE va fscks up again...
05:41 PM Crom: received my "claim" file it's missing all the service medical records
05:58 PM Crom: I need to build a bearing puller to remove the top bearing on my 400w spindle
06:01 PM * Jymmm hands Crom a plasma cutter
06:18 PM Crom: heh
06:21 PM andypugh: Is the bearing dead?
06:29 PM Loetmichel: Crom: stuck on the spindle or the housing?
06:30 PM Loetmichel: s/spindle/shaft
06:47 PM Crom: stuck on spindle
06:50 PM Jymmm: Crom: tourch or other heat source?
06:50 PM Jymmm: Crom: Ye old thermal expansion
06:51 PM Crom: I have the materials to make a puller... don't want heat that close to the comutator
07:41 PM Jymmm: andypugh: Well, that was a first for me... Repaired a MBP using a section of 1" 80/20
07:42 PM andypugh: Where is the 1” in the 80/20?
07:42 PM andypugh: Or do you not mean 80x20 extruded section?
07:43 PM Jymmm: andypugh: width of the 80/20, length was 3"
07:43 PM Jymmm: andypugh: Yep the extruded aluminum
07:44 PM andypugh: I imagine it isn’t the most elegant of repairs?
07:47 PM Jymmm: andypugh: Actually, it is. The body had been dented, so the bottom cover in one corner didn't seat properly. Removed the cover, disconnected the battery, removed the HDD, then grabbed a 1/8"x1/2" alumnum bar as a backer (as to not scratch the body), and then used the 80/20 as a "pry bar" to bend out the dented in section. Cover seats nicely now - and yes, the MBP still works as it should =)
07:47 PM andypugh: Right, so you made a tool, not a new part?
07:47 PM Jymmm: correct
07:48 PM Jymmm: The slots int he 80/20 fit PERFECTLY on the inner edge of the mbp body
07:49 PM Jymmm: andypugh: But, I would have never thought I'd be using 80/20 to repair a mbp =)
07:50 PM Jymmm: andypugh: a shotgun, sure. But not 80/20 =)
07:51 PM andypugh: You would need an anodised shotgun, of course.
07:51 PM andypugh: Anyway, sleep-time here.
07:51 PM Jymmm: lmao
07:51 PM Jymmm: andypugh++
07:51 PM * Jymmm google "apple shotgun"
07:55 PM Jymmm: iPhone vs shotgun https://i.ytimg.com/vi/gPhDO7EDGSM/maxresdefault.jpg
07:59 PM Jymmm: Oh the video is even better!!! https://www.youtube.com/watch?v=gPhDO7EDGSM
08:00 PM BeachBumPete: that is the best thing you can do with an iphone...
08:04 PM Crom_: over at the space... just found a 1hp 56 frame motor
09:07 PM evilroot: .join #diycnc
09:08 PM evilroot: Heh, oops
11:09 PM Gene_home: any advise regarding a diy coolant system for a cnc http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
11:34 PM Crom: make a siphon block... 1/4 drill for the short taper and a taper reamer for the long taper. drill a 1/32" drill ti the point where they meet. drill and tap for 1/8: npt thread and drill and tap the side from the taper reamer went for the in air 1/4 line to a ball valve and a 1/4 quick conect. on the outflow side 1/4" npt thread to hose to line lock nozzle.
11:35 PM Crom: 1/4" npt ball valve or a needle valve
11:37 PM Crom: oops backwards... air in side is the 1/4 drill side and the outflow is the tapered pin reamed side
