[02:27:34] <Deejay> moin
[05:27:59] <jthornton> morning
[06:10:53] <jthornton> http://www.thingiverse.com/thing:1821456
[06:10:53] <XXCoder> made another design eh
[06:11:21] <jthornton> yea, the corners would pull up and the bottom would not be flat so I lowered the temp by 5c and got rid of the corners and reduced the volume
[07:16:18] <Jymmmm> Can spring check valves be opened (to remove the spring)? http://www.ebay.com/itm/1-2-NPT-Brass-In-Line-Spring-Vertical-Check-Valve-Copper-Control-Tool-200WOG-/321871612781
[07:16:49] <Jymmmm> A different one with cross diagram http://www.ebay.com/itm/1-2-Brass-In-Line-Spring-Check-Valve-200WOG-/121170556823
[07:20:42] <archivist> a percentage others are riveted in
[07:21:58] <Jymmm> Ah, thank you.
[07:22:05] <Jymmm> Heh, this is cool... https://gfycat.com/detail/WaterloggedSorrowfulArmedcrab?tagname=Trending&tvmode=0
[07:24:04] <archivist> totally blank page on https://gfycat.com effin shite js page
[07:24:57] <Jymmm> archivist: Try this https://fat.gfycat.com/WaterloggedSorrowfulArmedcrab.mp4
[07:26:33] <Jymmm> I've always wanted to have a "mini me" vehicle inside/under my SUV. Thought it be great if you ever broke down of got stuck.
[07:26:44] <Jymmm> or*
[08:45:53] <AlSmt> anyone have schematics for chnc II 1986 vintage?
[08:53:47] <pink_vampire> XXCoder: ?
[08:56:06] <archivist> AlSmt, a few have have replaced the controls with linuxcnc
[08:56:25] <AlSmt> ya looking for some help
[08:57:44] <AlSmt> got the machine and no documents at all ,auction
[08:59:39] <AlSmt> fanuc 10t siemens servos
[09:00:54] <archivist> a runner, or ready for linuxcnc
[09:03:05] <AlSmt> might run said it ran in April
[09:06:52] <archivist> there is a large zip file with odd docs http://www.collection.archivist.info/archive/mirror/fanuc/
[09:09:23] <AlSmt> thanks i'll go look
[09:18:24] <AlSmt> archivist, you the man
[09:35:37] <AndChat|234416> AlSmt: might call the manufacturer and ask about a manual.
[09:37:56] <archivist> that would come with a large invoice I bet
[10:33:27] <MacGalempsy_> I would guestimate $100+ USD, maybe even$250+. However, it would be worth it if it cannot be found anywhere else. Try thewaybackmachine.net I have been able to find some good info, but it typically only goes back to the early 1990s.
[10:37:04] <archivist> I had a manual request from the designer of an item once
[10:37:57] <MacGalempsy_> lol. nice, which was it? I should scan and send you a couple of these different edm manuals
[10:38:35] <MacGalempsy_> how do auto scanners deal with 3-hole punched paper?
[10:41:53] <archivist> cannot remember which one it was, do remember seeing his name in the corner of the circuit diagram though
[10:45:24] <archivist> found it phase sensitive detector AIM PSD122A
[10:46:04] <Erant> Where do y'all get your bearings? I'm trying to find some 608Z or 608ZZ quality deep-groove bearings to see if I should make my own ball screw supports.
[10:48:29] <MacGalempsy_> Erant: ebay or amazon are always options.
[10:49:31] <gregcnc> too many fake bearings out there
[10:49:41] <Erant> Yeah, unfortunately you can't rely on shit there.
[10:49:54] <Erant> 608's are the worst, because they're skateboard bearings
[10:50:03] <gregcnc> you can likely find a local bearing supply
[10:50:08] <Erant> So you'll get ABEC-5's that are most certainly not ABEC-5.
[10:50:52] <Erant> Now, I could probably do with a genuine ABEC-3.
[10:51:04] <MacGalempsy_> NOS are good things to look out for. Something you know that was made before the onset of rollerblades.
[10:51:13] <enleth> Anyone familiar with USPS tracking here?
[10:51:25] <MacGalempsy_> yeah
[10:51:31] <Erant> enleth: Eh. I mean... I track a lot of packages :P
[10:51:37] <enleth> "Redelivery scheduled", "The customer has requested that the Postal Service redeliver this item on an unknown date" - what does "unknown date" mean here, exactly?
[10:51:58] <MacGalempsy_> never heard of that one before.
[10:52:01] <enleth> Unknown to USPS, unknown to customer, unknown to the tracking webapp?
[10:52:06] <MacGalempsy_> february 30th?
[10:52:21] <MacGalempsy_> enleth: what country are you in?
[10:52:34] <Erant> enleth: Eh, that tracking thing can be wack.
[10:52:42] <gregcnc> erant did you look at thrust loads?
[10:53:03] <enleth> It's in the SF right now, waiting to be picked up
[10:53:06] <Erant> Or rather, the mailman might have filled out the reason for missed delivery wrong.
[10:53:08] <enleth> Since 25th
[10:53:12] <Erant> Oh.
[10:53:18] <Erant> Time to call USPS.
[10:53:45] <MacGalempsy_> yeah, I was thinking just go to the local post office and see if they have the package sitting there
[10:53:48] <Erant> gregcnc: Of the bearings? My machine can't generate much more than 100lbs of cutting force anyway, so not too worried there.
[10:54:01] <enleth> It couldn't be delivered because the friend I sent it to is a fucking moron and didn't make sure to authorize someone to receive it
[10:54:28] <enleth> That's "Notice Left"
[10:54:46] <Erant> k, so is it at the postal office?
[10:54:48] <enleth> And next up it's "Redelivery Scheduled"
[10:54:56] <enleth> I hope
[10:54:57] <MacGalempsy_> sometimes if you request a signature and the person is not home, then they take it to the office
[10:55:11] <enleth> I'm trying to get the idiot friend to actually haul his sorry ass over there to get it
[10:55:29] <MacGalempsy> this heater takes forever to warm up...
[10:55:43] <gregcnc> that puts you right at the load limit for axial thrust assuming 25% of static radial laod.
[10:56:23] <MacGalempsy> going to print out a cruiser knob on the printer, then cnc the finishing cut. anyone know the sfm for abs?
[10:57:36] <gregcnc> enleth I was going to say most likely there wasn't anyone to receive the package, they will try the next day
[10:58:30] <Erant> gregcnc: Yeah, I was going to use two. Though I guess that doesn't matter, as only one will take the axial load at a time.
[11:00:29] <Erant> gregcnc: I was just going to preload with the ballscrew mounting nut thing.
[11:01:13] <gregcnc> standard bearings will still have clearance adding to your backlash
[11:01:36] <Erant> Are you saying MC0 bearings?
[11:02:21] <Erant> What I'm currently running is two thrust bearings, plus a needle roller bearing with a spring preload.
[11:02:51] <Erant> (Spring preload axially, obviously)
[11:03:55] <gregcnc> which are the 608?
[11:05:02] <Erant> That's what I'm looking at for my new ballscrews.
[11:05:16] <Erant> The current setup is for the ACME leadscrews.
[11:05:46] <Erant> (This from just looking at existing EK, BK and FK mounts)
[11:06:58] <gregcnc> small emco machines are built this way http://imgur.com/a/GmDmA two needle thrust, and a ball bearing for radial load from the belt
[11:08:59] <Erant> Maybe I'll just do that again. It'll mean pretty much guaranteed 0 backlash.
[11:09:15] <Erant> Plus I've got a Z problem.
[11:10:29] <gregcnc> otherwise a matched pair of angular contact with preload, but not common in 8mm
[11:10:47] <Erant> gregcnc: That's pretty much what I've got. Though my radial bearing isn't really doing anything.
[11:11:01] <Erant> I'm direct driving it right now.
[11:11:32] <Erant> But I might do a belt for the Y axis, reduce the annoyingly long stick out.
[11:11:34] <gregcnc> well it keeps things centered
[11:11:38] <Erant> Right.
[11:11:49] <Erant> I mean, I need it. It's not under much load.
[11:13:19] <gregcnc> The aerotech slides on my frankemill have a matched angular pair and a prelaoded nut. They are nice.
[11:13:31] <Erant> gregcnc: I've got a Bellevile washer in there right now. Should I switch to rigid preload, or is it 'eh, whatever'.
[11:13:45] <enleth> gregcnc: "next day" was two weeks ago, though
[11:13:47] <Erant> gregcnc: I was looking for angulars. They're hard to find that small.
[11:13:52] <enleth> almost three weeks
[11:13:56] <Erant> enleth: What does USPS say?
[11:14:28] <enleth> Erant: I pasted everything I had, the most important thing being "The customer has requested that the Postal Service redeliver this item on an unknown date in SAN FRANCISCO, CA 94133."
[11:14:30] <gregcnc> contact post office with tracking number should have been done right after they didn't come back with the package
[11:14:49] <enleth> and I'm wondering what does the "unknown date" mean here
[11:14:51] <Erant> enleth: Well, I meant, what did they say when you called them?
[11:15:17] <gregcnc> not relevant now
[11:15:34] <gregcnc> unknown date that is
[11:16:12] <enleth> Erant: so far I didn't, will do tomorrow if the idiot friend doesn't handle it as I've got enough stuff on my mind today
[11:16:57] <gregcnc> after three weeks it's either on the way back to origin or lost
[11:17:03] <Erant> Got it. Yes, calling USPS highly recommended. If it's been 3 weeks though... They don't keep packages at the post office for three weeks.
[11:17:07] <Erant> What gregcnc said.
[11:17:15] <Erant> You get, like, a week to pick it up.
[11:17:37] <enleth> oh well, we'll see
[11:17:57] <Erant> (And the tracker's not to be trusted if things don't go exactly to plan)
[11:18:26] <Erant> The moment the package goes off the rails, whatever it says is not reliable.
[11:19:00] <gregcnc> in 20 years I had only one package recently get lost. I sent a small part to a guy for free and it took like 3 weeks to get there. Probably jammed in a machine or fell off the conveyor based on the condition the envelope arrive in.
[11:20:31] <gregcnc> post office will look for it if you give them contents, I've heard of people getting stuff after months and from half way across the country
[11:22:37] <gregcnc> Erant vxb lists 708. they aren't matched preloaded pairs though
[11:24:19] <Erant> gregcnc: I mean, I'm not looking for 0.00001" backlash.
[11:24:36] <gregcnc> oh but you know you want it
[11:26:35] <Erant> ;)
[11:26:52] <Erant> vxb a good source then?
[11:28:33] <CaptHindsight> they have been
[11:31:52] <Erant> k, well, I'll probably just end up doing the thrust bearing thing again. Same bellevile washer to put some spring load on there.
[11:32:01] <CaptHindsight> gregcnc: that French lathe is not running
[11:32:25] <gregcnc> serious breakage?
[11:32:41] <Erant> CaptHindsight: Is it waving a little white flag?
[11:32:43] <Erant> (sorry)
[11:33:11] <CaptHindsight> haven't seen it, they say it needs an transformer
[11:33:29] <CaptHindsight> they were vague, but welcome to visit
[11:33:37] <gregcnc> maybe for 400V 3P
[11:33:55] <gregcnc> i have one
[11:44:02] <CaptHindsight> oh, well, no answer, mailbox full
[11:44:57] <CaptHindsight> looks like an auto shop
[11:45:09] <gregcnc> it has a nice tailstock
[11:47:59] <CaptHindsight> another paranoid or clueless seller, email reply with no info other than "8-5 excluding lunch"
[11:48:48] <gregcnc> no shortage of strange people
[11:49:30] <CaptHindsight> I'll ask to meet him at the nearby gas station :)
[11:49:58] <gregcnc> exactly
[11:56:44] <Jymmm> Erant: white flag... lmao
[11:57:39] <MacGalempsy> never!
[11:58:44] <Jymmm> MacGalempsy: Sit yer white flag wavin ass down biotch!
[12:00:29] <MacGalempsy> Jymmm: ouch. havent waved a white flag yet
[12:00:38] <MacGalempsy> im just getting started
[12:00:46] <Jymmm> lol
[12:02:00] <MacGalempsy> Jymmm: what are you working on?
[12:02:48] <Jymmm> MacGalempsy: outdoor wood fired heater for the garage
[12:05:39] <Jymmm> Well, that shut him up ;)
[12:06:06] <MacGalempsy> :)
[12:06:24] <MacGalempsy> brick or cement?
[12:06:39] <Jymmm> MacGalempsy: newspaper
[12:06:56] <Jymmm> MacGalempsy: Well, newspaper rack that is
[12:07:29] * MacGalempsy is confused... newspaper? lining or burning?
[12:07:34] <Jymmm> Now he's going WTF?! lmao
[12:08:45] <MacGalempsy> yeah, basically.
[12:08:50] <Jymmm> MacGalempsy: I got one of these for free http://www.raksystems.com/52btab.jpg and I'm going to line the inside with clay or fire brick to use as the firebox, then have a coil of copper tubing inside very much like a coffee maker works
[12:09:11] <SpeedEvil> copper may not be optimal
[12:09:15] <SpeedEvil> SS
[12:09:17] <SpeedEvil> perhaps
[12:09:23] <Jymmm> SpeedEvil: Why not?
[12:09:24] <MacGalempsy> ahhh. ok. I just mixed up 2 test cements yesterday evening
[12:09:37] <MacGalempsy> grog, fireclay, silica sand, perlite and water
[12:09:51] <SpeedEvil> I haven't properly investigated - I was just suggesting you might want to investigate
[12:10:15] <MacGalempsy> the plan is to let them dry until saturday and then let them dry a few more days uncovered
[12:11:06] <MacGalempsy> Jymmm: where are the copper tubes going? to a radiator?
[12:11:19] <Jymmm> SpeedEvil: Gotcha =)
[12:11:57] <SpeedEvil> what temperature is the glay going to get to?
[12:12:54] <MacGalempsy> https://flic.kr/p/N9wzMP Here are the ingredients for the cement. I.m hoping to max out the type-n thermocouple
[12:13:16] <Jymmm> MacGalempsy: It's sorta like this.. https://i.ytimg.com/vi/nAORPy4J6j8/maxresdefault.jpg
[12:13:47] <Jymmm> MacGalempsy: Excapt, I'm going to have a radiator in the garage
[12:13:59] <Jymmm> MacGalempsy: a car radiator that is
[12:14:34] <MacGalempsy> Jymmm: that should put out some good heat. you going to use the radiator fan assembly, too?
[12:14:48] <Jymmm> MacGalempsy: Well, I'm picking up a broken window AC this afternoon and going to try that first
[12:15:50] <Jymmm> I really have no clue on what capacities / volumes/ therms will be produced, I may have over/under actual results
[12:16:00] <MacGalempsy> Jymmm: That would be great, fan and radiator all in one
[12:16:27] <Jymmm> Yeah, I will use the fan, but I don't want to "HAVE" to
[12:16:40] <FinboySlick> If you can get it to work in reverse, an AC unit can be a great heat pump.
[12:16:58] <Jymmm> FinboySlick: HEat pumps don't work well below 45F
[12:17:19] <FinboySlick> Mine does fine at -25C.
[12:17:29] <FinboySlick> But it's built for that.
[12:18:00] <Jymmm> FinboySlick: you have something special than, not a typical heatpump
[12:18:30] <FinboySlick> It's not that special. 3k canadian peso.
[12:18:42] <FinboySlick> 18000 btu, two heads.
[12:18:56] <MacGalempsy> so three cups of coffee and a beer into the day, its time to run some power equipment
[12:18:58] <Jymmm> electric?
[12:19:03] <FinboySlick> Yes. 220v.
[12:19:43] <Jymmm> FinboySlick: I know there is a "TYPE" of heat pump that works below 45F well, but it's not common
[12:20:32] <FinboySlick> Jymmm: It has a mix of refrigerant fluid to be efficient along the whole range.
[12:20:55] <Jymmm> k
[12:21:19] <FinboySlick> I wouldn't live without it now. My house is rated at 11.5 full air changes/hour and is essentially just pretend-walls, yet it keeps the whole thing warm in harsh Canadian winters and cool in summer.
[12:21:40] <Jymmm> FinboySlick: Make and model?
[12:21:59] <FinboySlick> I'm looking it up. I'm pretty sure the compressor is made by mitsubishi, but the kit is not mitsubishi branded.
[12:22:49] <Jymmm> FinboySlick: Did the installers charge the system themselves? Custom formula?
[12:23:04] <FinboySlick> My buddy Terry did it, he's just a plumber.
[12:23:07] <gregcnc> dammit hungry again... when will it stop
[12:23:11] <FinboySlick> It's really quite easy to install.
[12:23:24] <MacGalempsy_> Jymmm: There is a space age fiber that looks like cotton stuffing that the local pottery place sells at $5/sqft. He fires pottery in there at 3000F [12:23:36] <MacGalempsy_> no mortar or brick required [12:23:39] <FinboySlick> It comes pre-loaded for the length of tubing you order with the machine. [12:23:50] <Jymmm> FinboySlick: ah [12:24:05] <Jymmm> MacGalempsy_: sounds liek ceramic fiber [12:24:18] <FinboySlick> To do it 'right' it's best to use a vacuum pump on the table before you let the gas in. [12:24:33] <FinboySlick> :s/table/tubing/ [12:24:53] <MacGalempsy_> for such a small rectangular box, it would be less than$100 to do that. Way easier than the mortar.
[12:25:27] <Jymmm> MacGalempsy_: So would picking up the 12" stepping stone stacked in the back =)
[12:27:40] <FinboySlick> Jymmm: https://senville.com/air-conditioners/18000-btu-aura/
[12:28:09] <FinboySlick> My only complaint is that the 'auto' computer isn't very clever and it tends to deadlock when one would heat and the other would cool.
[12:28:26] <FinboySlick> It's not smart enough to priorize one over the other so it just throws a fault.
[12:28:42] <Jymmm> MacGalempsy_: I have no clue how well this may or not work. So, before I go investing a lot into it, going to be as cheap as possible and then go/improve from there.
[12:28:48] <Jymmm> FinboySlick: heh
[12:30:39] <Jymmm> MacGalempsy_: I got the newspaper rack for free, paving stones I already have, will get the window AC for free, So basically need to find some copper tubing, a check valve, and some plastic tubing (cause I can't remember how much I have =)
[12:31:21] <Jymmm> MacGalempsy_: I'm still trying to figure out how to control the heat in the garage =)
[12:32:04] <MacGalempsy_> The biggest concern with the paving stones is to dry them out gradually, or they could explode
[12:32:28] <MacGalempsy_> set the AC unit to turn off the fan when it gets hot enough
[12:33:42] <Jymmm> MacGalempsy_: The wndow AC is broken, I'll be pulling it apart and using the condenser/evap coils
[12:33:59] <gregcnc> need to close the damper on the fire too
[12:34:58] <Jymmm> gregcnc: That's to slow the fire, this is going to be an open loop setup...
[12:35:20] <Jymmm> FinboySlick: thanks for the link
[12:35:22] <gregcnc> what happens when the water boils?
[12:35:50] <Jymmm> float valve
[12:35:56] <Jymmm> like in a swap cooler
[12:35:58] <MacGalempsy_> Put in a quarter and it turns off for 5 m in
[12:36:15] <gregcnc> ok that works too
[12:37:02] <Jymmm> gregcnc: the copper coil in the firebox may boil completely dry if I shut off the supply to it
[12:37:34] <Jymmm> gregcnc: Basically, think a giant coffee maker =)
[12:38:12] <Jymmm> just that it feeds back into the resrvoid instead of the coffee grounds =)
[12:38:12] <gregcnc> sure, not the most efficient, but easy and cheap
[12:38:31] <Jymmm> and safe
[12:39:22] <Jymmm> no pressure build up, no CO in the garage
[12:39:34] <Jymmm> if it runs dry, who cares
[12:39:47] <Jymmm> just no heat in garage =)
[12:40:33] <Jymmm> SpeedEvil: Know of and sources for cheap/salvageable SS tubing?
[12:41:06] <Jymmm> I only have one stick of thick wall that barley like to flex, much less bend =)
[12:41:51] <Jymmm> FinboySlick: how long have you had that? And how's you electric bill per winter months?
[12:44:35] <IchGucksLive> hi
[12:45:47] <gregcnc> 1.7kW in provides 5.3kW out, magic
[12:46:10] <Jymmm> gregcnc: Does it turn straw into gold too?
[12:46:30] <FinboySlick> Jymmm: I'm on my third year. It's pretty darn efficient, about 1/4 what it takes my conventional electric heater.
[12:46:51] <SpeedEvil> heat pumps are awesome
[12:46:51] <gregcnc> math says 1/3
[12:47:07] <Jymmm> SpeedEvil: not below 45F typically
[12:47:16] <SpeedEvil> Jymmm: depends on the generation of heatpump
[12:47:33] <SpeedEvil> there are ones that will work well at well below 20F
[12:47:48] <FinboySlick> Mine's rated up to -30C.
[12:47:51] <Jymmm> SpeedEvil: This one here is old and has electric hating elements too
[12:48:04] <Jymmm> for <45F
[12:48:56] <Jymmm> SpeedEvil: But the link FinboySlick gave me looks like it can run from 220V@7A circuit
[12:49:53] <FinboySlick> It doesn't have a heating element as far as I know.
[12:49:54] <Jymmm> And the unit we have now runs on 220V@ 40A + 50A circuits
[12:50:19] <gregcnc> what's the output though?
[12:50:37] <FinboySlick> 18000btu
[12:50:44] <Jymmm> gregcnc: It's OLD, no clue
[12:51:12] <Jymmm> 18000 BTU, is that PER head?
[12:51:19] <FinboySlick> No, 9k per head.
[12:51:36] <FinboySlick> Forced air.
[12:51:49] <Jymmm> FinboySlick: sq feet of your home?
[12:52:03] <FinboySlick> Um... 25x30, two stories?
[12:52:29] <FinboySlick> I have one head on each floor.
[12:52:41] <Jymmm> 25*30=750 * 2 = 1500
[12:53:41] <Jymmm> FinboySlick: How much is your electric bill in january?
[12:54:06] <FinboySlick> I'd have to check...
[12:54:26] <Jymmm> FinboySlick: ball park... $100$200 $400 ??? [12:55:20] <FinboySlick> They don't bill regularly, essentially they bill you when the guy can drive by and read the meter. Usually every couple months. Let me pull it out. [12:55:53] <Jymmm> The neighbor has (on avg in the winter) a$550/month, but she runs it constantly and is always cold.
[12:56:02] <Jymmm> USD
[12:57:29] <SpeedEvil> Jymmm: yeah - they have to be designed for it - it's much easier to make one that craps out at 45F
[12:57:34] <FinboySlick> 555 Canadian for 12/23/15 to 01/25/16
[12:58:15] <FinboySlick> Jymmm: And my house is a *sieve*.
[12:58:22] <FinboySlick> As in drafty.
[12:58:31] <gregcnc> http://www.usboiler.net/heat-loss-calculator.html
[12:58:57] <FinboySlick> gregcnc: I had it tested at 11.5 full air changes per hour.
[12:59:35] <FinboySlick> Wait, it's 11.5, but the per hour might not make sense.
[13:04:48] <FinboySlick> Well, nope... Pulled out the report, it's per hour.
[13:05:23] <FinboySlick> Bottom line, that thing is working like a little trooper.
[13:09:41] <Jymmm> FinboySlick: so that's $420/mo USD [13:10:14] <Jymmm> FinboySlick: whats the outside temp where your at in January? [13:14:50] <FinboySlick> Full month average is rated -10C but we get plenty of -24 -25 [13:15:12] <Jymmm> FinboySlick: ok, cool. ( no pun intended ;) [13:15:35] <FinboySlick> Average of -10C doesn't seem quite right. [13:19:20] <MacGalempsy> too cold for these bones [13:19:37] <MacGalempsy> I would like to do winters in Puerto Rico, its getting cheaper [13:33:37] <IchGucksLive> Gn8 [13:35:26] <jesseg> Is it bad manners for me to have my small CNC engraver to find home by moving slowlty at a low maximum current till it hits a hard stop and incurs a following error? It seems to work great, is simple and repeatable, and has the added benefit if a tool is caught in the action someplace, it'll halt without excerting full operating force [13:37:43] <jesseg> oops I should mention that I'm using brush type DC encoder motors. So no worries about losing step. [13:38:29] <CaptHindsight> jesseg: it may not be reapeatable indefinitely [13:39:12] <CaptHindsight> jesseg: is there an encoder involved here? [13:40:02] <CaptHindsight> heh, I guess brush type encoder motor would include an encoder [13:43:47] <CaptHindsight> jesseg: so you slowly crash the axis, get a following error and then you manually set that as Home? [13:44:34] <gregcnc> feature request: crash mode homing [13:46:44] <gregcnc> just like parking your car in chicago [13:46:46] <jesseg> CaptHindsight, well, it's automatic. The motor current is limited to far less than maximum operating torque, so it may be a crash but it's slow and in all respects below the operating speed and force. And the surfaces that meat are flat and square against eachother. Once it "crashes" then the position is read from the encoders while it's still against the stop, and that's 0,0 [13:48:03] <CaptHindsight> I'm happy with it if you are [13:48:03] <jesseg> It's just a small engraver with an air operated Z that clunks up and down with an air solenoid [13:48:04] <jesseg> :D [13:48:13] <jesseg> we're both happy then [13:49:20] <jesseg> It came to me as stepper motors, but I reworked it to use actually brushless encoder motors. I used my regular brush-type encoder PID controller board but modified it to support brushless [13:49:31] <gregcnc> how do you limit current just for homing? Seems like this would be handy on many machines as a failsafe [13:49:33] <jesseg> I'm not terrible fond of steppres [13:50:20] <jesseg> gregcnc, my little home brew PIC-based PID motor controller board lets the PC software set "Maximum duty cycle" on the pwm, which essentially limits the current at a stall based on coil resistance in the motor [13:51:03] <jesseg> so it just sets the maximum duty down low during homing, then sets it back up when done [13:51:12] <jesseg> because maximum duty also limits maximum speed :P [13:51:37] <jesseg> A fancy controller could actually measure and control current, even at high speeds [13:54:14] <gregcnc> ok makes sense [13:54:25] <nubcake> Hey there [13:55:00] <Erant> gregcnc: My servo drives support that too. [13:55:37] <gregcnc> maybe i've just overlooked this, erant which drives? [13:56:05] <Erant> http://www.applied-motion.com/products/servo-drives/bludc4-s [13:56:30] <Erant> Configurable over their wonky RS485 command bus. [13:56:49] <Erant> Which I still have to integrate with LinuxCNC. [13:58:43] <roycroft> so i have a question that is slightly off topic, but more on topic than most discussions here [13:58:54] <roycroft> i have an application where i need to lift a spindle precisely [13:59:02] <roycroft> just single axis movement [13:59:11] <roycroft> linuxcnc seems overkill for that [13:59:34] <Erant> Depends on the motion [13:59:35] <roycroft> is there something else folks use for such things that's compact (as in arduino/pi sized approximately) [13:59:41] <roycroft> simple [13:59:47] <roycroft> maybe keypad-driven [13:59:54] <roycroft> i don't think a full keyboard is necessary [13:59:54] <CaptHindsight> PLC? [14:00:00] <Erant> roycroft: GRBL? [14:00:09] <CaptHindsight> stepper, servo, encodes etc etc? [14:00:13] <Erant> It's not great, but it'll run on a... PI? [14:00:17] <roycroft> stepper is probably fine [14:00:33] <CaptHindsight> PLC [14:00:34] <roycroft> i just need to lift the spindle to a fairly precise height [14:00:38] <roycroft> lower it [14:00:41] <roycroft> raise again [14:00:43] <roycroft> the spindle is heavy [14:00:49] <roycroft> the leadscrew would have backlash [14:01:04] <roycroft> so probably any lowering operation would require lowering below target and lifting to target [14:01:18] <Erant> roycroft: How much programming do you want to do? [14:01:25] <roycroft> as little as possible :) [14:01:31] <Erant> Because that sounds like something you could write in an afternoon. [14:01:35] <CaptHindsight> gravity may cancel any lash [14:01:41] <roycroft> yes, capthindsight [14:01:45] <roycroft> which is why i would lower then raise [14:01:47] <Erant> CaptHindsight: It certainly doesn't for my head. [14:02:00] <Erant> CaptHindsight: Shit binds on the dovetails. [14:02:04] <Erant> (I'm fixing it, but...) [14:02:21] <roycroft> or are you saying gravity will always keep it at the bottome of the groove? [14:02:29] <roycroft> that's likely the case, actually [14:02:30] <CaptHindsight> precision motion on a worn machine that binds? [14:02:48] <Erant> In fact, I have a situation now where it looks like when you come back up, the head dips down a thou or two before coming up. [14:02:52] <_methods> http://www.geekbuying.com/item/K8-Intel-Z8300--Keyboard-Touchpad-MINI-PC-373070.html?source=ShareAsale [14:02:57] <_methods> strange roll uup computer [14:03:17] <Erant> CaptHindsight: Nah, this is a shitty Sieg X1. The Z axis dovetails are too short. [14:03:19] <roycroft> i don't need continuous motion at all [14:03:21] <CaptHindsight> nifty [14:03:27] <Erant> They're too short for the weight. [14:03:28] <roycroft> just lift to a particular height, then hold [14:04:05] <CaptHindsight> gregcnc: lathe sold at 8am today [14:04:09] <roycroft> so a little scripting on a pi or arduino, and a stepper motor, is probably what i need? [14:04:26] <gregcnc> it was cheap unless scrap [14:04:32] <jesseg> roycroft, how fast does it need to be? Steppers can be pretty slow [14:04:35] <roycroft> it would be nice to auto-zero the tooling [14:04:39] <roycroft> slow is fine [14:04:50] <roycroft> total lift will be in the 10cm range [14:05:03] <jesseg> roycroft, steppers are easy to auto zero. Just run it 50cm in one direction, and it'll be at zero LOL [14:05:31] <CaptHindsight> gregcnc: there must be several watchers for lathes on CL [14:05:37] <roycroft> a touch plate is what i'm thinking [14:06:10] <gregcnc> well i think between WI, IL, and IN there are a few [14:06:44] <Erant> roycroft: Like, with a strain gauge? [14:07:29] <Erant> I thought about that. I'd rather have an optical method though. [14:07:49] <roycroft> no [14:07:59] <roycroft> spindle lifts until tooling touches the metal plate [14:08:05] <roycroft> which closes a circuit that indicates zero [14:08:17] <CaptHindsight> _methods: no PCI/e, SPI. LPT or nufin [14:08:18] <Erant> Lifts? [14:08:28] <roycroft> raises up [14:08:46] <roycroft> the spindle will be mounted below the work [14:08:47] <Erant> Is this a horizontal spindle then? [14:08:50] <roycroft> vertical [14:08:51] <Erant> Ah [14:08:56] <Erant> Got it. [14:08:57] <roycroft> it's a wood router [14:09:05] <roycroft> i wasn't meaning to be coy [14:09:39] <Erant> Yeah, the metal plate thing works if you're going to be running exclusively conductive tooling. [14:09:42] <roycroft> i have a router lift, and want to motorise it and cnc it [14:10:30] <_methods> CaptHindsight: yeah i just thought it was kinda interesting [14:10:53] <CaptHindsight> _methods: I've seen several over the years [14:11:10] <CaptHindsight> but this one folds [14:11:12] <_methods> i've never seen one like that that had everything in one roll up [14:11:50] <_methods> just needs a roll up monitor lol [14:12:02] <CaptHindsight> thinking the same :) [14:12:10] <CaptHindsight> where would I use it? [14:12:22] <_methods> roll up monitor, inflatable cnc [14:12:31] <_methods> and you can use it in the ocean on your inflatable raft [14:12:57] <CaptHindsight> hope I didn't forget the batteries and inverter [14:13:47] <Erant> roycroft: So the easiest thing for your lift is probably something like GRBL. a PLC will work, but might be pricier. [14:14:18] <Erant> It does 'software' step generation and whatnot, and you can connect a USB keyboard to it. [14:14:45] <CaptHindsight> _methods: I'd like one in khaki canvas with frayed edges [14:15:54] <_methods> hehe [14:16:29] <CaptHindsight> with matching monitor and battery pack/power supply [14:17:14] <CaptHindsight> they usually do a poor job with the keyboards [14:18:09] <CaptHindsight> looks like a silicone keyboard [14:18:27] <CaptHindsight> I tried one for a while with backlit keys [14:18:46] <roycroft> yeah, i'm looking at the grbl wiki [14:18:51] <roycroft> it probably does what i need without much fuss [14:22:53] <FinboySlick> You want a proper IBM keyboard, with keys that sound like a centerpunch ;) [14:24:13] <FinboySlick> ka-Klunk! [14:33:02] <roycroft> i want siri [14:33:07] <roycroft> "siri, make my part while i drink beer" [14:33:24] <nubcake> http://9gag.com/gag/aYL24Ov?ref=fbp [14:33:36] <gregcnc> siri turn my part into scrap [14:33:37] <nubcake> last image is so true :o [15:39:12] <nubcake> do i have to connect all 4 axis-drivers to the EN terminal on my eBay BOB ? (there's only 1 EN, the one before had one for every axis) [16:23:11] <Deejay> gn8 [16:26:25] <[fields]> what non plastic materials can a typical 3d printer print? [16:27:33] <nubcake> pla i guess? [16:27:43] <XXCoder> theorically, low temperate metals [16:28:09] <XXCoder> but nobody ever tried that. I suspect it turns into too liquid for it to retain shape when past hotbox [16:28:24] <nubcake> might need a freezebed then i guess? :D [16:28:28] <XXCoder> unless you have cold air setup or something. yeah [16:42:11] <CaptHindsight> [fields]: please define "typical 3D printer". FDM/reprap? [16:42:45] <jdh> Ti [16:44:56] <MacGalempsy> step one is recognizing there is nothing "typical" about this channel [16:46:21] <CaptHindsight> I guess it is its own step program [16:46:29] <Jymmm> CaptHindsight: 3D printer = cube of wax and blow torch [16:46:55] <CaptHindsight> Jymmm: huh, not hot grits and butter? [16:47:09] <FloppyDisk525> Pizza, all 3d printers print pizza... [16:47:37] <roycroft> pizza sounds good [16:47:44] <roycroft> i might make a pizza for dinner tonight [16:47:46] <MacGalempsy> I tried to 3d Print a knob and then machine it. However, the shrinkage made the final product too small. Printing out an oversized knob now to see if I can get it to look good [16:48:07] <CaptHindsight> pastes may be easily deposited by a similar extruder used by FDM printers [16:48:07] <FloppyDisk525> nubcake - either yes, or connect the enable to a relay and have that goto the enables [16:48:22] <Jymmm> CaptHindsight: hot chick and butter [16:48:31] <roycroft> are you saying i need a 3d printer to do that? [16:48:36] <CaptHindsight> non plastic pastes [16:49:11] <CaptHindsight> roycroft: are you referring to organic pastes? [16:49:26] <FloppyDisk525> nubcake - Depends on your machine as well, but you want to be able (I think you might) to disable all drives if needed at the same time. Hence the enable. [16:49:30] <roycroft> i should hope my pizzas ar organic [16:49:33] <roycroft> are [16:49:41] <FloppyDisk525> But, for a small mill, like a sherline or something, eh, do whatever... [16:50:14] <FloppyDisk525> you have to pay extra for 3d printed organic pizza... [16:50:59] <Jymmm> I'm guessing that's 3/8" aluminum tubing in the coil, but how many feet to you think it is? https://i.ytimg.com/vi/nAORPy4J6j8/maxresdefault.jpg [16:51:24] <nubcake> FloppyDisk525, i didn't even think about that disable all axis with that 1 contact, just wondering if that's ok/normal to enable all with just 1 connector [16:52:02] <CaptHindsight> Jymmm: is this an whoever is closest or do you have to be exact to win the prize? [16:52:15] <FloppyDisk525> 2 issues I can think of... one is how many wires into a small screw terminal, usually 2 or 1 is desired. So use some terminals like: [16:52:30] <Jymmm> CaptHindsight: just a guesstimate so I know how much to buy [16:52:40] <FloppyDisk525> http://www.wago.us/products/rail-mounted-terminal-block-systems/overview/ [16:53:00] <FloppyDisk525> Also, #2 is Current... How much can be supplied and how much will be used? Don't want to burn out that enable output. [16:53:16] <CaptHindsight> Jymmm: 4 loops and whats the dia? [16:53:18] <FloppyDisk525> Normally, stepper drives draw milliamps for the enable, like 20ma [16:53:33] <FloppyDisk525> So, you're probably fine. If you can a spec great, if not, try it... [16:53:38] <Jymmm> CaptHindsight: o clue, I was gussing it's 3/8" OD [16:53:53] <CaptHindsight> Jymmm: dia of the outer loop? [16:54:05] <Jymmm> FloppyDisk525: Wait, are you disabling steppers how? [16:54:19] <FloppyDisk525> I like to break out w/ terminal blocks, but that's just me. You could put them all in a wire-nut thingy and wire that into the enable. [16:54:20] <Jymmm> CaptHindsight: no clue [16:54:37] <CaptHindsight> Jymmm: 8ft should be more than enough [16:54:45] <nubcake> FloppyDisk525, i thought of maybe using a (not sure if its the right term) coupler relais, finder 24v coil NC/NO for that [16:54:46] <FloppyDisk525> Jymmm - unless I've had too much beer, nubcake has a BOB w/ an enable 'OUTPUT' that goes to the stepper drivers. [16:54:50] <Jymmm> FloppyDisk525: You typically disablr steppers on the DRIVE, not the motors [16:55:06] <FloppyDisk525> I'm talking drive here... enable on the drive. [16:55:22] <Jymmm> FloppyDisk525: then why would amperage matter ? [16:55:43] <FloppyDisk525> amperage matters for all this bob stuff because you can only draw so much... [16:55:49] <FloppyDisk525> If the inputs draw too much, you'll fry the output. [16:55:50] <nubcake> already got some wago terminal blocks to use [16:56:21] <Jymmm> FloppyDisk525: You're not DRIVING anything, it (should) just be a signal, but check the specs [16:56:24] <FloppyDisk525> I have no idea of the hardware he's using, so you always (imo) want to look at the current used by the input side (stepper driver) and what the output side can supply... [16:56:43] <Jymmm> CaptHindsight: I'd guess it's 6-8" wide [16:56:48] <FloppyDisk525> Unless Ohm was lying about his law, a signal takes some level of current... [16:57:03] <FloppyDisk525> And, I like to keep smoke in:-) [16:57:08] <Jymmm> FloppyDisk525: not if it was optical =) [16:57:23] <FloppyDisk525> Very low level:-) [16:57:39] <Jymmm> FloppyDisk525: Fine.... LICK IT [16:57:42] <FloppyDisk525> you're right, you could also have some high impedence type input that doesn't take much either... [16:57:50] <FloppyDisk525> current. [16:58:48] <CaptHindsight> Jymmm: you boiling water on demand over an open fire pit? [16:59:12] <Jymmm> CaptHindsight: closed firebox [17:00:20] <Jymmm> CaptHindsight: coil like you see piped to radiator in garage. BUT... this will be an OPEN loop system and there will be a reservoir with a float valve to top off [17:01:07] <Jymmm> CaptHindsight: a car radiator that is =) [17:01:32] <CaptHindsight> Jymmm: diameter x 3.14 x number of loops will be more than enough since the coils get smaller but... [17:01:43] <Jymmm> CaptHindsight: or evaporator from window AC if this guy ever calls me back =) [17:02:07] <Jymmm> CaptHindsight: https://www.youtube.com/watch?v=nAORPy4J6j8 [17:04:54] <Jymmm> woohoo, he called back... now to go pick up the (broeken) AC andgrab the evaporator out of it =) [17:06:18] <CaptHindsight> http://www.intmath.com/blog/mathematics/length-of-an-archimedean-spiral-6595 [17:07:22] <Jymmm> CaptHindsight: WTF is this shit?! http://www.intmath.com/cgi-bin/mathtex.cgi?\large{L=\int_{a}^{b}\sqrt{r^2+\left%28\frac{dr}{d\theta}\right%29^2}d\theta} [17:07:24] <Jymmm> lol [17:07:37] <Jymmm> bbiab [17:07:50] <Jymmm> CaptHindsight: ty, so was that 10 or 20ft? [17:07:59] * Jymmm snickering [17:08:25] <CaptHindsight> depending on diameter tes [17:08:30] <CaptHindsight> tes/yes [17:08:56] <CaptHindsight> try it with some rope [17:10:36] <roycroft> j ##homebrew [17:10:48] <roycroft> do not ever try to lift a full carboy with one of those neck handles [17:11:17] <roycroft> ack, mischan [17:40:23] <JT-i3> printing a mount for my EZ Struder [17:43:29] <Tom_L> what's your next one gonna be? [17:44:34] <JT-i3> undecided at this point lol [17:44:47] <JT-i3> better and bigger than this one lol [17:44:58] <Tom_L> cause nobody just builds one... [17:45:06] <JT-i3> lol [17:46:03] <JT-i3> this one turned out pretty good for the price, a few improvements and it's as good as the expensive 200x200x200 printers [17:46:25] <Tom_L> what did you change on it? [17:48:43] <JT-i3> the first thing I did was take some shipping tape and make the fit better for the extruder idler roller and the X axis bearings and the bottom of the Z axis rods [17:49:39] <JT-i3> the rest was just tweaking the configuration.h file till I got what I expected then learn what temp/feed/speed/layer height worked well with the PLA [17:50:10] <JT-i3> first thing I had to do was make the extruder spit out 50mm when you told it to [17:51:28] <JT-i3> the$40 EZ Struder should help and it has a release button for easy changing of the filament

[19:42:38] <dioz> anyone here familiar with the milwaukee multi-charger station?
[19:42:58] <dioz> if i had 3 x bosch chargers could i cut the ends off and just wire them all together and plug them into one outlet?
[19:51:31] <andypugh> dioz: I think the question is not if you could, but if you should :-)
[19:55:25] <dioz> i wanna put them all inside a tool box
[19:55:32] <dioz> and fasten them to the bottom
[19:55:39] <dioz> so i can leave all the batteries in one box
[19:55:56] <dioz> instead of having 2 in the drill box, 2 in the recip saw box, 2 in the grinder box
[19:56:17] <dioz> this way i just take one box with all the chargers and all the batteries to a wall
[19:56:20] <dioz> plug it in
[19:56:22] <dioz> and i can charge all my shit at once
[19:57:49] <Frank_3> hello :)
[19:58:57] <dioz> i could get a 3 to 1 power plug i guess

[20:13:27] <witnit> why not call it a print?
[20:13:29] <zeeshan> put it in a 4 jaw chuck
[20:13:29] <Frank_3> i have to send it to do it
[20:13:37] <zeeshan> and flatten the corners on the lathe

[20:18:00] <zeeshan> i can make that for a gazillion dollars :)
[20:18:10] <Frank_3> thats like 2 cents right ? hehe
[20:18:37] <Frank_3> ill ask how much they charge me in the shop close to me
[20:18:45] <Frank_3> would that part need a lot of precision??
[20:18:57] <zeeshan> only where the bearing goes
[20:19:27] <Frank_3> i have a mitutoyo caliper, i guess i can control the part with that
[20:19:36] <Frank_3> and wont need an ID micrometer
[20:21:18] <zeeshan> usually you need a micrometer
[20:21:39] <zeeshan> cause a bearing's OD is 0 to -0.0005" tolerance
[20:22:01] <zeeshan> which means you need to aim for -0.0005 to 0.0015
[20:22:06] <zeeshan> to achieve a decent press fit
[20:22:11] <zeeshan> for the hole
[20:22:15] <Frank_3> crap
[20:22:30] <zeeshan> thats easy to do w/ a cnc mill or lathe
[20:22:35] <zeeshan> nothing major..
[20:22:46] <gregcnc> manual even
[20:23:18] <Frank_3> but i dont think the shop around the corner has a micrometer to check the accuracy of the hole
[20:23:35] <Frank_3> thanks for the info on the tolerance
[20:23:39] <gregcnc> machine shop with no mic?
[20:24:16] <Frank_3> *facepalm*
[20:26:03] <zeeshan> Frank_3: you dont really need any special tools to check
[20:26:20] <zeeshan> they can configure their dro by machining the od of your part
[20:26:28] <zeeshan> and then machine the id after and it'll be dead on
[20:26:38] <zeeshan> provide them a sample bearing
[20:26:41] <zeeshan> so they can check the fit
[20:27:10] <Frank_3> they have only manual lathes
[20:27:41] <Frank_3> but i guess with the sample bearings they would do the job
[20:28:10] <Frank_3> (no dro)
[20:28:40] <zeeshan> theres a lot of ways to measure that id
[20:28:47] <zeeshan> im sure they have telescoping gauges and a micrometer
[20:28:55] <zeeshan> gages
[20:28:55] <Frank_3> i was thinking on this: but they are all adjustable
[20:40:49] <enleth> is imgur.com throwing 503 with a blank screen for anyone else?
[20:41:03] <witnit> nay
[21:08:52] <MacGalempsy> hello
[21:09:10] <BeachBumPete> hey mac
[21:10:06] <MacGalempsy> hey pete. whats going on tonight?
[21:10:31] <BeachBumPete> been busy out in the shop you?
[21:11:15] <MacGalempsy> just turning it down for the evening.
[21:11:22] <BeachBumPete> nice
[21:11:51] <BeachBumPete> I moved my CNC lathe to its new home position and have been working on moving stuff around to prepare for the arrival of the VMC
[21:11:58] <MacGalempsy> spent the day trying to finish cut a printed cruiser knob today.
[21:12:18] <MacGalempsy> will the sit in the same room?
[21:12:32] <BeachBumPete> yeah same room
[21:13:25] <BeachBumPete> I also found the chord rack that used to be mounted to my tig welder and got it mounted back on there and tidied up that area
[21:13:38] <MacGalempsy> ended up printing a 3x3x2cm stock, but the stringy nature of the print played havoc on the final product
[21:13:46] <Frank_4> i think i have a virus :( my internet is so slow on this pc
[21:13:59] <BeachBumPete> what sort of printer do you have?
[21:15:47] <MacGalempsy> it started as a mendlemax 1.5
[21:16:28] <MacGalempsy> haveall the stuff for a new printer, just need to finish the bracketd
[21:17:52] <BeachBumPete> seems like that printer JT is using is kinda neat and has the admirable trait of being cheap as well ;)
[21:20:16] <MacGalempsy> my whole cnc mill effort started because my plastic tuning skills are limited...
[21:20:46] <CaptHindsight> buckle up for the revolution in manufacturing!!
[21:20:50] <MacGalempsy> ive had it for about 3 or 4 years now. i have a love hate relationship with it
[21:20:55] <BeachBumPete> well I currently have no plastic tuning skills so don't feel bad
[21:21:29] <CaptHindsight> BeachBumPete: all was well when you returned home?
[21:21:41] <BeachBumPete> huh?
[21:21:48] <CaptHindsight> the storm
[21:21:54] <BeachBumPete> I never left home
[21:22:00] <BeachBumPete> and yes all is well
[21:22:11] <CaptHindsight> oh, I thought somebody said you left for a few days
[21:22:36] <BeachBumPete> no we shuttered up the house and slept while the 85 mph winds whistled by :)
[21:22:46] <BeachBumPete> worst part was losing power for 3 days
[21:22:57] <tiwake> sounds like fun
[21:23:09] <tiwake> and why propane is the best
[21:23:19] <CaptHindsight> 85mph, that like a wednesday in Chicago :)
[21:23:37] <Tom_L> or Ks
[21:23:45] <BeachBumPete> losing power was no fun but we camped out in the family room around a borrowed portable AC unit and had a big generator out back watching movies so that was ok
[21:24:20] <MacGalempsy> sounds like roughing it. did you have cold beer?
[21:24:27] <BeachBumPete> well the storm supposedly had 140 mph winds but it ran by us by about 50 miles offshore
[21:24:49] <jdh> parts of I-95 and I-40 are still flooded here
[21:24:54] <BeachBumPete> so I figure as did the local meteoroligists that we saw actual winds in the 85-90MPH range
[21:25:20] <MacGalempsy> missing any shingles?
[21:25:36] <BeachBumPete> its kinda funny my friends here said that they had not had a serious storm in almost a decade and I come down here and three months later we have a doozie
[21:25:49] <BeachBumPete> no no shingles missing that I could see
[21:26:35] <BeachBumPete> getting kinda excited now that I have the shop cleaned up and have things positioned finally to allow the VMC to be moved in. Possibly tomorrow night
[21:27:17] <MacGalempsy> whats the first project on your list?
[21:27:31] <BeachBumPete> I removed a hanging flourescent light fixture and this ugly ass light from the ceiling in the shop so it clears easily and I am gonna put the florescent light above my Tig welding station.
[21:27:59] <BeachBumPete> first project is to get it leveled up, setup, and hook everything back up so I can start hooking power back up to it.
[21:28:14] <BeachBumPete> I had to unhook quite a few wires from the control cabinet
[21:28:53] <BeachBumPete> I decided to finally break down and lower that very tall electronics cabinet so the machine can go thru a standard garage door without modification.
[21:29:17] <MacGalempsy> luckily my small mill has the cabinet on the back of the enclosure.
[21:29:18] <BeachBumPete> that required me to reroute several wires so I unhooked them and labeled them and just tied them off.
[21:29:35] <BeachBumPete> yeah my machines cabinet is on the back of the enclosure as well
[21:30:08] <BeachBumPete> but originally they tucked the bigass power transformer box underneath it so the machine could be hooked up to varying voltages of different countries etc.
[21:30:21] <BeachBumPete> don't need that anymore so I removed the whole box and transformer
[21:30:37] <BeachBumPete> which left like a foot and a half space underneath the electronics cabinet
[21:31:20] <BeachBumPete> I took advantage of this and lowered the cabinet down to just above the adjusting pods bases so the overall height of the machine was considerably shorter now.
[21:32:26] <BeachBumPete> I took my Kurt vise and my cheap chinese CNC vise out of the boxes yesterday and started oiling them up
[21:32:44] <BeachBumPete> I found my slotted cast iron angle plate and oiled it as well.
[21:33:12] <MacGalempsy> the southern humidity put a rust on quickly
[21:33:15] <BeachBumPete> I also found the monster heavy tailstock for the CNC lathe in another box and got it up on my bench so I can start working on repainting and oiling that up too.
[21:33:26] <BeachBumPete> meh not so far
[21:34:08] <BeachBumPete> I always used to spray bare metal down with WD40 or similar tho just in case.
[21:35:05] <BeachBumPete> I was thinking about building a pair of mobile leveling bases for the CNC lathe's base feet so I can move it around easier to work on the retrofit
[21:35:25] <BeachBumPete> right now it is still atop the 4x4 skids I used to move the machines with
[21:35:27] <MacGalempsy> how much does it weigh?
[21:35:36] <BeachBumPete> like just under 4k
[21:36:13] <MacGalempsy> will leveling casters bolt up without a frame?
[21:36:20] <BeachBumPete> its funny it is NOT all that much bigger than my old 12x36 in overall size but it is nearly four times as heavy LOL
[21:36:49] <BeachBumPete> I don't know
[21:37:09] <BeachBumPete> the machine has four leveling screws studs whatever they are
[21:37:22] <BeachBumPete> they are like an inch and a half diameter or so
[21:37:39] <BeachBumPete> the bad part is that they are NOT at the extreme corners of the base feet
[21:38:22] <BeachBumPete> so if you put some sort of caster underneath using those positions you would be a bit unstable due to the position or at least less stable then you could be were they at the extreme corners
[21:41:59] <BeachBumPete> but it sure would be nice to be able to just roll it around to work on it.
[21:43:03] <MacGalempsy> yep. someday i hope to have a heavy duty gantry in my shop
[21:43:28] <jdh> next to my waterjet
[21:43:34] <MacGalempsy> yeah
[21:44:13] <BeachBumPete> I don't think I would want a waterjet machine
[21:44:27] <jdh> it would be cool for a few days
[21:44:54] <BeachBumPete> I guess so but I think that is a machine I will just pay to use someone elses
[21:45:04] <MacGalempsy> by the time i get something that big, i will have minions to operate it 24/7
[21:45:57] <BeachBumPete> well at least your minions could do the clean up and maintenance on it
[21:46:29] <MacGalempsy> are they messy?
[21:46:41] <BeachBumPete> I wonder how hard it would be to make a set of casters for the machine
[21:47:07] <MacGalempsy> ive seen 1000lbs casters
[21:47:14] <BeachBumPete> I think so. the one I was using at the last shop was nasty. at least the results of the cutting was
[21:47:56] <BeachBumPete> large shovelfuls of the media mixed with whatever you were cutting which was usually steel of some sort so it was this big mess of nasty rusty red garnet sludge
[21:49:21] <MacGalempsy> huh. that stuff is probably hell on the plumbing
[21:49:41] <BeachBumPete> yup
[21:49:46] <zeeshan> MacGalempsy: i found gold
[21:49:47] <zeeshan> ;-)
[21:50:10] <zeeshan> wish it was nuggets
[21:50:15] <zeeshan> fine code :D
[21:50:17] <zeeshan> *gold
[21:50:38] <zeeshan> haha
[21:50:42] <zeeshan> i got those exact same skates
[21:51:01] <zeeshan> handled my 11000 lb lathe
[21:51:02] <zeeshan> :D
[21:51:51] <MacGalempsy> zeeshan: nice! you going to stake a claim?
[21:51:57] <zeeshan> no
[21:52:08] <zeeshan> theres no way i have the resources to mine that
[21:52:14] <zeeshan> i dont even know how much there is
[21:52:17] <zeeshan> but its there
[21:54:45] <BeachBumPete> I think I might have to make some of those skates
[21:55:18] <zeeshan> suggestion
[21:55:23] <zeeshan> i need to do this mod still
[21:55:29] <zeeshan> notice how the guy uses flat plate
[21:55:44] <zeeshan> i'd pocket the flat plate
[21:55:50] <zeeshan> so you could fit a plywood piece inthere
[21:56:02] <zeeshan> asap the skate is unloaded, the plywood piece wants to fly out
[21:56:19] <zeeshan> i think ill pocket mine 1/8"
[21:56:19] <BeachBumPete> or you could just tig weld some small ledges to the edges
[21:56:25] <zeeshan> yes or that
[21:57:08] <BeachBumPete> the plywood has the added effect of taking up any variances hopefully keeping the skates under the machine
[21:57:42] <zeeshan> ive moved 4 machines with them so far
[21:57:46] <zeeshan> on flat concrete floor
[21:57:51] <zeeshan> it seems like no matter what i did
[21:57:59] <zeeshan> i could only get 3 of them to be loaded at any given time
[21:58:08] <zeeshan> the 4th one was just teeter tottering
[21:58:16] <zeeshan> makes sense cause the floor isnt 100% flat
[21:58:30] <BeachBumPete> is this WITH the plywood or without?
[21:58:34] <zeeshan> with
[21:58:44] <zeeshan> as you move the machine around
[21:58:47] <zeeshan> the 4th one gets loaded
[21:58:51] <zeeshan> and another one loses the load
[21:59:00] <zeeshan> but you still need it there cause it'll shift weight
[21:59:13] <BeachBumPete> yeah I have used the pro machine skates several times now and experienced much the same thing
[22:00:10] <BeachBumPete> my experience with the ones I rented leaves me with something that I think makes these actually safer in that they are so short in height. The ones I rented were like three and a half inches tall
[22:00:31] <BeachBumPete> if the machine were to fall off of that height it would have a ways to go until it hit the ground
[22:00:35] <zeeshan> yea
[22:00:40] <BeachBumPete> possibly causing a tipover
[22:00:42] <zeeshan> initially i only had 4 bearings total
[22:00:46] <BeachBumPete> these appear to be QUITE short
[22:00:48] <zeeshan> they worked fine until i moved the 11000lb
[22:00:49] <zeeshan> lathe
[22:00:59] <zeeshan> i blew up the bearings after a few pushes
[22:00:59] <zeeshan> lol
[22:01:05] <BeachBumPete> did you use 1/2 plate like he did?
[22:01:09] <zeeshan> yes
[22:01:14] <BeachBumPete> what size axles?
[22:01:18] <zeeshan> i did the calculation
[22:01:37] <zeeshan> i dont remember the numbers for the loads per bearinb
[22:01:49] <zeeshan> but it worked out to be able to have 15,000lb capacity w/ some buffer
[22:01:52] <zeeshan> you definitely need 8 bearings
[22:01:57] <zeeshan> i used 1" axles
[22:02:05] <BeachBumPete> what did you use skate bearings?
[22:02:15] <zeeshan> i think 6202-2rs-1
[22:02:18] <zeeshan> i'll need to check
[22:02:28] <BeachBumPete> wow 1" seems huge
[22:03:01] <BeachBumPete> I was thinking 1/2 inch shafts and perhaps 1" OD bearings or something like that
[22:04:00] <zeeshan> thats why i used it
[22:04:08] <zeeshan> that way they didnt need any machining
[22:04:11] <zeeshan> just slip the bearings on
[22:04:14] <BeachBumPete> ya know something I just realized
[22:04:41] <BeachBumPete> I could probably just use this method and tig weld the axle directly to the lathe baseplate
[22:05:12] <BeachBumPete> put two on one end and then put one that can swivel on the other end or something
[22:05:35] <BeachBumPete> because once it is where I need it you adjust the leveling feet to get it all nice and level
[22:06:06] <BeachBumPete> I am sure those feet go higher than the axle and half the bearing
[22:06:25] <zeeshan> mine sit about 25-50 thou above the steel plate
[22:06:30] <zeeshan> but with the plywood in between
[22:06:32] <zeeshan> its enough clearance
[22:06:48] <zeeshan> depends on what od bearing you get
[22:07:03] <BeachBumPete> did you just press on the bearings like he did or is there a keeper of some sort?
[22:07:12] <zeeshan> press fit
[22:07:25] <BeachBumPete> ok
[22:07:31] <zeeshan> if i could go back
[22:07:31] <BeachBumPete> they look dead simple really
[22:07:37] <zeeshan> i should have tap and drilled the ends
[22:07:40] <zeeshan> and keep a keeper
[22:07:47] <zeeshan> just as extra safety
[22:07:55] <zeeshan> its too much work to do that now
[22:08:03] <BeachBumPete> just a hole and cotter pin and washer would work fine I think
[22:08:14] <zeeshan> i didnt make the shafts long enough
[22:08:14] <zeeshan> lol
[22:08:27] <zeeshan> i only got like 1/16" of room extra
[22:08:30] <zeeshan> after you put in the bearings
[22:08:46] <BeachBumPete> they never traveled while moving the machines tho right
[22:09:09] <zeeshan> nope
[22:09:13] <BeachBumPete> nice
[22:09:36] <BeachBumPete> it would sure be nice to be able to move the VMC and the lathe wherever I want without too much drama
[22:10:10] <BeachBumPete> I am hoping when they bring the VMC here they can use that ram like the other guy did and push the machine into position for me so all I have to do is jack it up onto the pods
[22:10:36] <BeachBumPete> the CNC lathe is here but the VMC is coming hopefully tomorrow if I can get the truck here
[22:10:42] <zeeshan> nice man!
[22:10:47] <BeachBumPete> yeah its about time
[22:10:50] <zeeshan> you'll be back into the machining action :D
[22:10:57] <BeachBumPete> Can't wait
[22:11:00] <zeeshan> in a month or ill be starting the lathe build
[22:11:03] <zeeshan> been too long :D
[22:11:12] <BeachBumPete> my customers have been ringing me up for weeks wanting parts made
[22:11:13] <zeeshan> or 2
[22:11:20] <zeeshan> haha
[22:11:24] <zeeshan> nice
[22:12:14] <BeachBumPete> I will honestly just be happy to NOT have to pay the 225 dollar storage rental fee
[22:12:36] <zeeshan> jesus thats a lot
[22:12:54] <BeachBumPete> its not a little :(
[22:13:04] <BeachBumPete> it was for a 10x20 unit tho
[22:13:25] <BeachBumPete> I actually had two of them one 10x10 and the other 10x20
[22:13:39] <BeachBumPete> was paying like 375 a month for them both
[22:13:58] <zeeshan> are you all moved in to your house?
[22:13:59] <BeachBumPete> once we got the new house I quickly emptied the smaller one out
[22:14:09] <BeachBumPete> yes its very nice now
[22:14:14] <zeeshan> sweet man
[22:14:16] <zeeshan> you're living the life :d
[22:14:22] <zeeshan> beautiful weather
[22:14:24] <zeeshan> close to the ocean
[22:14:25] <zeeshan> :D
[22:14:30] <BeachBumPete> its more expensive but it sure is nice to NOT have to work on the house anymore
[22:14:51] <BeachBumPete> yeah its very nice when the hurricane is not threatening ;)
[22:15:15] <BeachBumPete> it has been REALLY beautiful here since the storm went thru
[22:15:34] <BeachBumPete> weather is in the low 80s and nice and sunny and breezy
[22:16:03] <zeeshan> a ltitle bit of wind aint hurt no one
[22:16:04] <zeeshan> :d
[22:16:43] <zeeshan> are you on the east coast
[22:16:50] <zeeshan> or west coast of the pan handle
[22:17:07] <BeachBumPete> central east coast
[22:17:11] <zeeshan> ah
[22:17:13] <zeeshan> so you got hit bad
[22:17:14] <BeachBumPete> about an hour north of Palm Beach
[22:17:22] <zeeshan> thats where the peak winds were recorded
[22:18:11] <BeachBumPete> http://imgur.com/a/qhEZQ
[22:18:32] <zeeshan> need to tie the vmc and lathe to your roof
[22:18:39] <zeeshan> house will be impossible to break
[22:18:40] <zeeshan> :)
[22:18:52] <BeachBumPete> http://imgur.com/a/PJrmi
[22:18:59] <zeeshan> nice
[22:19:02] <zeeshan> i'm jealous! :{
[22:19:13] <BeachBumPete> I took those pics from the condo I am working in a couple days ago
[22:20:05] <BeachBumPete> It really is beautiful man. I missed it living in Tennessee. Even the hurricane didn't spoil it for me ;)
[22:20:44] <BeachBumPete> I had my Kayak right off that beach two weekends ago fishing offshore
[22:20:54] <zeeshan> what did you catch
[22:21:02] <zeeshan> i've been getting hardcor einto fishing
[22:21:08] <zeeshan> =D
[22:21:29] <BeachBumPete> I caught some blue fish and a small snapper I was not out there very long
[22:21:56] <zeeshan> nice
[22:22:07] <BeachBumPete> I actually got kinda seasick LOL
[22:22:08] <zeeshan> i fished the ocean during a trip this summer
[22:22:22] <zeeshan> i caught an atlantic salmon and a bunch of mackarel
[22:22:38] <zeeshan> those mackarel put up a fight
[22:22:38] <zeeshan> haha
[22:22:42] <BeachBumPete> it was a bit choppy that day and after breaking thru the shore break I think I tired myself out paddling out and when i finally got out there Id had it
[22:22:50] <zeeshan> i dunno how you kayak
[22:22:52] <zeeshan> that shit is scary
[22:22:56] <zeeshan> i'll never do it
[22:22:59] <BeachBumPete> Oh yeah mackeral is great
[22:23:08] <BeachBumPete> what is scary about it?
[22:23:12] <zeeshan> flipping upside down
[22:23:14] <zeeshan> and dieing
[22:23:15] <zeeshan> :)
[22:23:24] <BeachBumPete> Oh man my kayak is VERY stable
[22:23:32] <BeachBumPete> its like 35 inches wide
[22:23:42] <zeeshan> there was a kayak tour at bay of funday (sees very large tides)
[22:23:48] <BeachBumPete> its not your typical kayak
[22:23:50] <zeeshan> i said.. hell effing no.
[22:23:50] <zeeshan> :P
[22:24:15] <BeachBumPete> the new fishing kayaks they sell now are quite stable. Most people can stand up and fish in them
[22:24:15] <zeeshan> i was watching videos online
[22:24:34] <BeachBumPete> I don't stand in mine but I have before
[22:24:36] <zeeshan> someone who knows how to kayak knows how to react when you're about to to flip over
[22:24:44] <zeeshan> theres some pedalling you can do
[22:24:46] <zeeshan> to prevent
[22:25:02] <BeachBumPete> I ALMOST flipped coming back in thru the shore break tho.
[22:25:19] <BeachBumPete> the surfers were out there because the waves were kinda high
[22:25:34] <BeachBumPete> i got turned sideways a bit and the next wave nearly tossed my ass over
[22:25:36] <zeeshan> ill stick to a tin can!
[22:25:54] <BeachBumPete> but I jumped out and grabbed the boat so it did not float away
[22:26:10] <BeachBumPete> It was already shallow enough to stand up in tho.
[22:26:22] <zeeshan> youre going to get eaten by a shark or alligator!
[22:26:39] <BeachBumPete> thanks for jinxing me man
[22:26:45] <zeeshan> im just kidding :P
[22:26:59] <BeachBumPete> there are some BIGASS sharks around here tho
[22:27:17] <BeachBumPete> some guy recently caught a 13 foot hammer head off the beach on the west coast
[22:27:29] <zeeshan> lol wtf
[22:27:32] <zeeshan> they were fishing for sharks?
[22:27:33] <zeeshan> :D
[22:27:38] <BeachBumPete> that's a monster man
[22:27:47] <BeachBumPete> yeah they were fishing for sharks
[22:27:59] <BeachBumPete> they used a small stingray to catch it apparently
[22:28:14] <BeachBumPete> you don't accidentally catch a 13 foot hammer head
[22:28:18] <zeeshan> haha
[22:28:22] <MacGalempsy> shark is tasty
[22:28:24] <BeachBumPete> you gotta have some serious equipment
[22:28:25] <tiwake> you kinda can
[22:28:35] <zeeshan> i bet you need a special spool
[22:28:48] <BeachBumPete> he had a very heavy duty setup
[22:28:49] <zeeshan> you prolly generate so much heat
[22:28:55] <MacGalempsy> pete you may nee to cnc some fishing equipment
[22:28:56] <BeachBumPete> lemme see if I can find the story
[22:28:56] <zeeshan> that'd break an average real in no time
[22:29:01] <tiwake> I cant imagine fishing being fun without alcohol
[22:29:08] <zeeshan> MacGalempsy: i want to make a custom spool
[22:29:14] <zeeshan> tiwake: what!
[22:29:19] <zeeshan> it's so much fun without being drunk
[22:29:25] <zeeshan> beautiful scenery
[22:29:29] <zeeshan> enjoy :P
[22:29:42] <tiwake> zeeshan: I've been fishing before... fly fishing, bobbing, out in the sea fishing... meh
[22:30:09] <zeeshan> http://i.imgur.com/uD0LZyH.jpg
[22:30:13] <zeeshan> still my fav pic from the summer
[22:30:32] <tiwake> though it might be more fun if there were not so many regulations and gotta get fishing license... etc etc.
[22:30:43] <tiwake> oops, that one is not a clipped fin
[22:30:45] <tiwake> screw that
[22:31:08] <zeeshan> ROFL
[22:31:11] <zeeshan> at the size of that spool
[22:31:59] <BeachBumPete> that is a HUGE damn fish man
[22:32:54] <BeachBumPete> one of the guys on the South Florida Kayak fishing Facebook page has video of one like this swimming around his kayak for like ten minutes
[22:32:55] <MacGalempsy> yeah. only 30 min to reel in. thats like transparent aluminum line!
[22:33:25] <BeachBumPete> well they were fishing off the beach so it was probably not that far off shore when they hooked it
[22:33:29] <zeeshan> ive been trying to catch northern pike
[22:33:32] <zeeshan> but no luck so far
[22:33:56] <tiwake> then you gotta take it home, wash all the equipment so it does not rust, flay/skin the fish
[22:34:04] <MacGalempsy> live bait?
[22:34:11] <zeeshan> nahh
[22:34:15] <zeeshan> been trying jerkbait
[22:34:16] <tiwake> ok NOW its time to start thinking about cooking it
[22:34:35] <MacGalempsy> i like trout fishing
[22:34:54] <MacGalempsy> most around here are bass and catfish
[22:35:18] <BeachBumPete> trout is good fish
[22:35:28] <zeeshan> we got lots of fish here
[22:35:39] <BeachBumPete> I never really liked bass and catfishing
[22:35:56] <zeeshan> bass, fucking carp, fucking goby, yellow perch, cat fish, northern pike, pickerel, muskie
[22:36:04] <LoveMHz> now I want to see the follow up news article about how the pissed off hammer head drags someone from the same beach around for 30 minutes and "lets them go"
[22:36:09] <zeeshan> salmon, all your varieties of trout :D
[22:36:47] <BeachBumPete> its nice to have a variety of fish species to catch
[22:36:50] <zeeshan> no sharks tho!
[22:36:54] <MacGalempsy> as kids we did crabbing. now that is better with beer
[22:36:55] <BeachBumPete> that is one of the things I love about Florida
[22:37:03] <BeachBumPete> I love crabbing
[22:37:06] <BeachBumPete> and clamming
[22:37:17] <tiwake> the government ruined clamming too
[22:37:28] <BeachBumPete> they try to ruin about everything huh
[22:37:55] <tiwake> gotta get a permit for freaking cockles
[22:38:06] <zeeshan> im glad the gov steps in
[22:38:11] <zeeshan> theres too many savages out there
[22:38:19] <zeeshan> i was fishing the creek the other day
[22:38:23] <zeeshan> salmon littered everywhere
[22:38:25] <BeachBumPete> we fish often from a bridge that spans the intercoastal waterway here
[22:38:30] <tiwake> moved to montana for three years, come back to oregon and now you cant even get cockles cause permits
[22:38:30] <zeeshan> people cutting them up just for roe
[22:38:32] <zeeshan> so fucking stupid
[22:38:39] <tiwake> zeeshan: tell that to the seals
[22:38:46] <BeachBumPete> its amazing the variety of fish we catch there using the same damn bait live shrimp LOL
[22:38:51] <zeeshan> seals?
[22:39:04] <tiwake> wanna talk about savages to fish?
[22:39:22] <zeeshan> wasting fish meat
[22:39:23] <BeachBumPete> damn I better get to bed
[22:39:25] <zeeshan> is savagery
[22:39:25] <zeeshan> :P
[22:39:33] <BeachBumPete> Gn8 guys
[22:39:34] <tiwake> take a bit, leave the other half
[22:39:42] <tiwake> *bite
[22:40:02] <zeeshan> cya
[22:40:23] <tiwake> zeeshan: didnt used to have fish "shortages" until seals were put on the protected list
[22:40:23] <Tom_L> mmm. missed it all
[22:42:34] <tiwake> oh, he left
[22:43:04] <tiwake> well, if he likes the government, he can continue living on whatever coast he is at
[22:43:04] <renesis> seals are neat
