01:03 AM IchGucksLive: morning from Germany
01:05 AM roycroft: hallo
01:08 AM Crom: He lowered shipping to $75...morning
01:12 AM roycroft: https://portland.craigslist.org/mlt/bfs/6165472155.html
01:13 AM roycroft: this is somewhat interesting
01:14 AM IchGucksLive: does someone know wheere to bye good precicion Cheep planaetary gears like neugart ple60
01:17 AM archivist: planetary gears= a number of meshes=backlash= less precision
01:24 AM IchGucksLive: for wood it is good
01:24 AM IchGucksLive: i think i will go with that worm http://www.maedler.de/product/1643/1331/1978/1367/schneckengetriebe-hi-bis-226-nm-i751-bis-1001
01:44 AM LeelooMinai: IchGucksLive: How much is that thing?
01:49 AM IchGucksLive: 120
01:55 AM IchGucksLive: LeelooMinai: there are CHEEP NMRV on the net for Half the price
01:56 AM IchGucksLive: take a look on ali or bay
01:57 AM LeelooMinai: I recently saw a reducer like that locally for USD 75 or so, but no idea if it was any good, 1:60 I think
02:01 AM LeelooMinai: Found it. But out of stock: https://www.princessauto.com/en/detail/60-1-horizontal-shaft-aluminum-worm-gear-speed-reducer/A-p8607392e
02:13 AM IchGucksLive: LeelooMinai: https://www.aliexpress.com/wholesale?ltype=wholesale&d=y&origin=y&isViewCP=y&catId=0&initiative_id=SB_20170606224129&SearchText=NMRV&blanktest=0&tc=af
02:33 AM Deejay: moin
02:52 AM archivist_herron: bookmark
02:52 AM the_wench: yet another log is at http://emclog.archivist.info/
04:48 AM XXCoder: boo
04:49 AM XXCoder: LeelooMinai: dont worm gear have backlash?
04:55 AM jthornton: morning
04:56 AM XXCoder: hey jt
04:58 AM jthornton: what's up today
04:59 AM XXCoder: I broke record for the poart im working on
04:59 AM XXCoder: 27 parts
05:00 AM Tom_L: now they'll expect it all the time
05:00 AM XXCoder: nah
05:00 AM XXCoder: they expect 24 or so
05:00 AM XXCoder: thats my typical
05:01 AM jthornton: what kind of part?
05:01 AM XXCoder: im one of fastest workers there
05:01 AM XXCoder: belt cover from what i understand
05:01 AM XXCoder: I rarely know what part is for
05:09 AM XXCoder: jthornton: making anything?
05:12 AM jthornton: working on some cargo carry things for the Spyder and moving a bunch of stuff from the old shop
05:12 AM XXCoder: nice
05:12 AM XXCoder: whats you do for work if not too curiouis
05:13 AM jthornton: my main work is automation when I can get jobs doing that
05:13 AM XXCoder: oh yeah you recently had this job to automate umm cutting of one part
05:18 AM XXCoder: one of best smbc ones. http://www.smbc-comics.com/index.php?db=comics&id=1638#comic
05:21 AM gcardinal: Anyone tried this sensor with linuxcnc https://www.sorotec.de/shop/3D-Finder---3D-Messtaster-6411.html ?
05:22 AM XXCoder: dang its worth almost as much as my whole machine frame.
05:24 AM jthornton: looks like a nice one for 360 eur what ever that is
05:25 AM XXCoder: jthornton: telsa solar roof is sold out all way to 2018
05:25 AM XXCoder: dang.
05:26 AM XXCoder: its solar roof that has infinity warranty as well as better life than average roof while generating power, and from what i understand, only modest price increase
05:26 AM jthornton: what is that?
05:26 AM XXCoder: no wonder it sold out so hard
05:27 AM XXCoder: https://futurism.com/tesla-has-sold-out-of-solar-roofing-tiles-well-into-2018/
05:33 AM gcardinal: I cant stand Tesla... :P
05:33 AM XXCoder: whats wrong with telsa
05:34 AM XXCoder: imange getting this concept and building a true 4d cnc machine https://www.youtube.com/watch?v=0t4aKJuKP0Q
05:34 AM XXCoder: some ops thats so hard with 3d 5 axis machine would be very simple
05:34 AM gcardinal: XXCoder thinking its environmental friendly.
05:35 AM gcardinal: here is a video of sensor in use https://youtu.be/jtBLnZd7nqE?t=8m58s
05:35 AM XXCoder: and it isnt?
05:36 AM gcardinal: I think its even more damaging then regular cars
05:36 AM XXCoder: cars?
05:36 AM XXCoder: wtf
05:37 AM XXCoder: im talking about solar roof not cars
05:37 AM gcardinal: yeah but reason I cant stand Tesla is becouse of the cars - roofs are ok :)
05:38 AM XXCoder: batteries is BIG issue we have right now
05:38 AM XXCoder: no wonder theres so many groups researching on batteries
05:38 AM XXCoder: I think some group is trying to make sodium version of lathinium ion
05:38 AM XXCoder: much cheaper and easier to get
05:38 AM gcardinal: but no one wants to talk about what happens to batteries when they die...
05:38 AM XXCoder: nice video
05:39 AM XXCoder: recycling works usually
05:39 AM XXCoder: and sadly phones laptops and such is much worse source of techinical junk dump\
05:39 AM XXCoder: cars lasts years
05:39 AM XXCoder: phones maybe 2? for average customer
05:41 AM gcardinal: tesla last for about 5 years
05:41 AM gcardinal: but thats 2t not 200g
05:41 AM XXCoder: thats not too bad. I think they actually buy battery packs back
05:41 AM XXCoder: because its always 2 or 3 cell that go bad not all at once
05:42 AM XXCoder: you can fix drill battery in similiar way. try to recharge it to full couple times
05:42 AM XXCoder: then pull apart and indivually check cells for charge, theres always 1 or 2 dead cells, replace those and get back together
05:42 AM XXCoder: its like new again
06:02 AM gcardinal: XXCoder but what to do when the ones which are dead?
06:03 AM XXCoder: eat it
06:03 AM XXCoder: recycle it really, its mostly lathinium ion anyway which should be very recycleable.
06:04 AM XXCoder: I recently read about new terminals design that dont slowly break apart like latghinium ion ones do
06:04 AM XXCoder: so battery life is vastly longer
06:13 AM XXCoder: gcardinal: https://futurism.com/new-instantly-rechargeable-battery-deals-a-fatal-blow-to-fossil-fuels/
06:13 AM XXCoder: I read all batteries inventions stories with grain of salt because so many of em never pan out.
06:20 AM jthornton: https://universal-solder.com/product-category/arduino-boards-modules/
07:25 AM gcardinal: XXCoder yes but also emc2 - moving 1 person in a 2t car - wont buy into "green" alternative here
08:10 AM sync: XXCoder: suprisingly solar cells are going to be a recycling issue
08:20 AM JT-Shop: judging from the turd pile on the hand rail what ever knocked the feeder down was a pretty big coon
08:21 AM Loetmichel_: JT-Shop: not enough foundation then for the feeder
08:21 AM Loetmichel_: all your fault
08:21 AM Loetmichel_: :-)
09:28 AM SpeedEvil: sync: what?
09:28 AM SpeedEvil: sync: The silicon in the solar cells in a typical ~20kg solar panel are ~0.8kg or so.
09:29 AM sync: but what about the lead?
09:29 AM SpeedEvil: There is no lead in modern solar panels.
09:29 AM SpeedEvil: The solder is not lead based.
09:30 AM sync: there is lead in modern solar cells
09:30 AM sync: quite a lot actually
09:30 AM SpeedEvil: sync: where?
09:30 AM sync: in the busbars
09:30 AM SpeedEvil: Why do you think it's lead, and not lead-free alloy
09:30 AM sync: because I developed busbar compounds?
09:31 AM roycroft: even if there were lead, what's the concern about it?
09:31 AM SpeedEvil: sync: when?
09:31 AM sync: two years ago
09:31 AM sync: it is leaded glass with silver
09:31 AM sync: and will always be
09:31 AM sync: due to the way the contact works
09:32 AM SpeedEvil: Which busbar are you referring to?
09:32 AM sync: the screenprinted busbars on the front and the back
09:32 AM sync: of course there are backside connected cells, but still they need some way of contacting those
09:33 AM sync: and they will contain lead
09:41 AM SpeedEvil: I find some limited research indicating silver is an alternative, but lack of decent data. I was assuming you were meaning difficulty in seperating out the silicon for recycling - wasn't thinking of lead. And indeed some of the panels (including the one I have) do use lead free solder to attach to the (probably lead based) metalisation. Interesting
09:42 AM sync: there is motion to go lead free, but it is difficult to achieve low contact resistances
09:44 AM SpeedEvil: http://www.murata.com/en-eu/about/newsroom/techmag/metamorphosis16/productsmarket/newenergy
09:44 AM SpeedEvil: I guess you could simply chip the panel, and treat it mostly as glass contaminated with lead.
09:44 AM SpeedEvil: As leaded glass.
09:45 AM sync: actually it is metallic lead
09:45 AM SpeedEvil: But, the demand for leaded glass for recycling is AIUI negative
09:45 AM SpeedEvil: Not once you heat it to glas melting point
09:45 AM sync: as the lead will come out of solution
09:45 AM sync: it is not that easy tho
09:46 AM SpeedEvil: you could I suspect manufacture leaded glass from it moderately easily, which nobody wants.
09:47 AM sync: probably, but overall the recycling issue is bigger than people might think
09:48 AM SpeedEvil: If lead contamination of refuse is actually a problem.
09:51 AM * SpeedEvil wishes he could get more solar laminates.
10:08 AM * jym shoves SpeedEvil thru the pasta roller machine, glues him to a room to have sun exposure all yer long! There, you are now a solar laminate ;)
10:09 AM SpeedEvil: (solar laminate = a conventional solar panel, but without teh aluminium edge - got some cheap)
10:15 AM jym: SpeedEvil: Nice, I'd life to play with some of those.
10:15 AM jym: like*
10:16 AM jym: SpeedEvil: a 15-30W that I could put on the roof of my car would be awesome!
10:16 AM SpeedEvil: jym: these are flat. you can getflexy ones
10:17 AM SpeedEvil: http://www.ebay.co.uk/itm/Peel-Stick-136-watt-Uni-Solar-Laminate-Solar-Panel-Flexible-24v-Unisolar-/281803084464?hash=item419cc5d2b0:g:0eYAAOxyOMdS6E2F
10:17 AM SpeedEvil: That is a damn reasonable price
10:17 AM jym: SpeedEvil: oh, they roll up?
10:17 AM SpeedEvil: (though a little long for most cars)
10:17 AM jym: SpeedEvil: I have a full sized SUV
10:18 AM SpeedEvil: 216" of roof?
10:18 AM SpeedEvil: https://youtu.be/7MBaEEODzU0?t=232 - related.
10:19 AM jym: Well, technically I do have 18ft, but not optimal for solar panel of course =)
10:20 AM SpeedEvil: you'd want multiple shorter ones, I suspect.
10:21 AM jym: or a single 50/100W panel that I couldn't mount on the roof, but it's okey, not something I'll be working on anytime soon. I do have my foldable panel, its 15W and does well, just ment for portable use, not a permanent install.
10:23 AM skunkworks: http://www.machsupport.com/forum/index.php/topic,29259.10.html
10:23 AM skunkworks: or just use linuxcnc.
10:30 AM cradek: oh come on, we've only had that for 20ish years
10:32 AM SpeedEvil: jym: the above panel, if slicable into 3 strips might work nearly ideally. I think shorter ones are available
10:33 AM CaptHindsight: duinos or apps solve just about everything
10:33 AM jym: CaptHindsight: world peace?
10:34 AM CaptHindsight: sure
10:35 AM jym: CaptHindsight: WOOHOO
10:54 AM roycroft: whirrled peas?
11:05 AM LeelooMinai: Er
11:09 AM LeelooMinai: It's about ballscrews being not ideal, right? I don't get that "X axis Calibration Data Chart - what are horizontal numbers representing there?
11:14 AM SpeedEvil: presumably offsets from linear?
11:17 AM LeelooMinai: Hmm... that must have been some pretty bad ballscrew then - almost 1mm error over 8 inches...
11:18 AM LeelooMinai: Unless this is not just ballscrew/leadscrew data, but whole axis and there's something else happening there.
11:19 AM LeelooMinai: Cannot imagine a screw from any factory that bad.
11:19 AM IchGucksLive: hi from Germany
11:19 AM SpeedEvil: LeelooMinai: maybe you're reading it wrong, could it be 1 thou?
11:20 AM LeelooMinai: No, top is 40 = 1mm
11:21 AM IchGucksLive: Q someone is on Grabvad
11:21 AM IchGucksLive: cad
11:22 AM LeelooMinai: I am on few of those site - ie have account so I can get models.
11:22 AM LeelooMinai: Often get electronic components models from those.
11:23 AM LeelooMinai: For Altium
11:23 AM IchGucksLive: what is the hint there do i ned to upload models regular or only download if i got some upöoded
11:23 AM LeelooMinai: I just download without any problems.
11:23 AM IchGucksLive: i need a Step from a shoe sole
11:23 AM LeelooMinai: lol...
11:24 AM LeelooMinai: No idea what what you are doing there - cobbling? :)
11:24 AM IchGucksLive: today i got a polnish class on cnc plasma and foam
11:25 AM IchGucksLive: but most er oly interested at sculpting
11:25 AM IchGucksLive: ok till later
11:26 AM LeelooMinai: I google shoe sole 3D model and went to imasge view - tons of those.
11:36 AM LeelooMinai: Fail. Saw this on YouTube and thought it's kind of a good idea, but they are nuts with those prices: https://www.amazon.ca/KATRIS-Scratcher-Modular-Furniture-L-Shape/dp/B00HUBLK4M/ref=sr_1_1?ie=UTF8&qid=1496851459&sr=8-1&keywords=Katris
11:37 AM LeelooMinai: I thought "o, cool, made from recycled paper, so one piece probably $5" :)
11:38 AM gregcnc_ is now known as gregcnc
11:48 AM CaptHindsight: https://www.technologyreview.com/s/604088/the-3-d-printer-that-could-finally-change-manufacturing/
11:51 AM LeelooMinai: CaptHindsight: At this point I don't really want people to have access to cheap metal printers - they will probably print guns and kill everyone around:/
11:52 AM CaptHindsight: metal powder with inkjet binder and then sintered using microwave
11:53 AM LeelooMinai: That probaly does not have properties of a "normal" alloy.
11:53 AM phipli: morning
11:54 AM LeelooMinai: I may be wrong, but my first thought would be that it will be like cheap cast metal.
11:54 AM LeelooMinai: I mean one of those that break easily.
11:56 AM LeelooMinai: "In a series of carefully calibrated steps during the sintering process, the polymer is burned off, and then the metal is fused together at a temperature well below its melting point."
11:56 AM LeelooMinai: Right, that won't be very strong.
11:57 AM roycroft: how much time do you have to spend getting those parts to look decent after 3d printing them?
11:58 AM LeelooMinai: Well, that's less of a problem imo
11:58 AM jym: roycroft: 10x longer than it took to hotglue them in the first place... it's called MOLD INJECTION ;)
11:59 AM jym: ..sub $1000 unots that is
11:59 AM LeelooMinai: It's just a matter of refinement of technology, better resilution, etc. - eventually it will get at a point, where it won't need post-processing.
11:59 AM jym: units*
11:59 AM * roycroft foresees a tremendous growth in the grinding and buffing industries if 3d metal printing is widely adopted
11:59 AM LeelooMinai: But more of a problem is stryctural strength imo.
11:59 AM LeelooMinai: structural*
11:59 AM jym: $80K metal 3d printing is AWESOME. It's the sub $1000 that suck
12:00 PM roycroft: i guess you could mount those 3d printed boltes in your lathe and do a cleanup pass on the threads with a single point tool
12:00 PM jym: LeelooMinai: Use it as a mold to cast real thing.
12:00 PM roycroft: bolts
12:00 PM LeelooMinai: jym: Right, they probably do that already a lot, but, that's not really solution, just compromise.
12:02 PM jym: LeelooMinai: It IS a solution. You are looing at it from a IT process. But consider what it takes to just create a MASTER mold, then it's a non issue.
12:02 PM jym: JIT*
12:03 PM jym: There is no all-in one solution for eveything, this aint star trek, there are no replicators , mkay
12:03 PM LeelooMinai: I mean solutiuon for an average Jane to do it at home:)
12:03 PM roycroft: i agree that there is a lot of potential for 3d printing
12:03 PM roycroft: mass-manufacturing high quality parts is not currently one of them
12:03 PM LeelooMinai: No ne will make casts at home and build a forge to do that:p
12:04 PM LeelooMinai: Well, no one average at least - I am sure there are nerds and crazy people that do.
12:05 PM gregcnc: why would it be an issue? you design to the material properties
12:06 PM LeelooMinai: gregcnc: ...
12:08 PM gregcnc: crappy products made of crappy materials are produced daily for people who want crap or don't care
12:08 PM CaptHindsight: jym: thank you for putting it in terms that the common man can understand, mkay lol
12:08 PM LeelooMinai: I guess that's the path Flintstones went - they designed everything to wood and stone:)
12:09 PM roycroft: welcome to the wal*mart world, gregcnc
12:09 PM roycroft: make crap
12:09 PM roycroft: sell crap
12:09 PM roycroft: buy crap
12:09 PM roycroft: use crap
12:09 PM roycroft: buy crap again
12:09 PM jym: CaptHindsight: Live long and kiss my ass! ;)
12:10 PM LeelooMinai: roycroft is not familiar with Rules of Acquisition:)
12:10 PM CaptHindsight: thank you again South Park for your clarity of the situation
12:10 PM jym: CaptHindsight: lmao
12:12 PM jym: CaptHindsight: RUSPECT MUH ATHORATEEE
12:13 PM gregcnc: commercial I saw the other day https://youtu.be/cpprlfnSxEw
12:13 PM LeelooMinai: Fail - wood bit on metal:)
12:14 PM CaptHindsight: Desktop Metal is after making components that can't be made by casting or injection
12:15 PM CaptHindsight: I've gotten lots of files for parts that can only be made with additive processes
12:17 PM CaptHindsight: https://d267cvn3rvuq91.cloudfront.net/i/images/mj17-3dmetal5.jpg?sw=1080&cx=0&cy=0&cw=1000&ch=1334 you can't cast or machine that part
12:17 PM CaptHindsight: well at least as one piece
12:17 PM cradek: you could edm it
12:17 PM gregcnc: what's interesting is that it's changing the way things are designed
12:18 PM Loetmichel_: LeelooMinai: see it as a win: she can do drilling with a wood bit in metal. She must be good in what she does ;)
12:18 PM CaptHindsight: not sure what the webbing looks like inside that part
12:19 PM Loetmichel_: CaptHindsight: that picture is perfectly doable
12:19 PM Loetmichel_: not with a hollow part without
12:19 PM Loetmichel_: infill though
12:19 PM LeelooMinai: Obviously - if one day they figure how to make parts as strong as machined metal (probably with nano-scale carbon lattice, etc.) it will change anything.
12:19 PM Loetmichel_: but the visible part is no problem with injection moding aluminium
12:20 PM Loetmichel_: LeelooMinai: they already can
12:20 PM gregcnc: but what if you only need 10 pieces?
12:20 PM Loetmichel_: laser sinter of stainless steel dust, then put into casting sand, then infuse with molten brass
12:20 PM CaptHindsight: if the inside has webbing or internal structures then it's 3d only
12:20 PM LeelooMinai: I would even say it's inevitable, but, technology is not a problem - more of a problem is peeople lagging behind and olbiterating Earth before that happens.
12:21 PM Loetmichel_: CaptHindsight: thats what i just said
12:21 PM CaptHindsight: as one piece
12:21 PM CaptHindsight: me too
12:21 PM Loetmichel_: external visible webbign is not a problem tho
12:22 PM LeelooMinai: Well, it's 2.5 structure - you can just machine it.
12:22 PM LeelooMinai: Or cheat and machine layers and put them together as laminate.
12:24 PM gregcnc: without a print it's fun to guess
12:24 PM Loetmichel_: LeelooMinai: i thought about that
12:25 PM Loetmichel_: making layers on the CNC mill and then welding them together with ultrasound
12:25 PM LeelooMinai: So, if they make magic metal glue that is cheap, safe, and binds metal sheets with strength, that would in itself open a lot of possibilities without any changes to machinery.
12:25 PM Loetmichel_: they do
12:25 PM Loetmichel_: there are epoxy and PU glues out there that come damn near aluminium strenght
12:25 PM Loetmichel_: ask the car industry ;)
12:26 PM LeelooMinai: Loetmichel_: Well, something must be wrong with them... To expensive? Not as strong as steel?
12:26 PM CaptHindsight: the real problem is that all these 3d printer vendors are greedy and controlling, they don't want to share tech...
12:27 PM Loetmichel_: CaptHindsight: obviously
12:27 PM LeelooMinai: CaptHindsight: That applies to any vendor:)
12:27 PM CaptHindsight: often the problem is solved by combining one or more methods
12:27 PM gregcnc: isn't every engineers dream to be awarded a patent and live it up?
12:27 PM Loetmichel_: what did you expect from a company that wants to earn money?
12:28 PM CaptHindsight: but they only want you to use their one method and with their materials
12:28 PM LeelooMinai: gregcnc: How about - er, no? :)
12:28 PM CaptHindsight: so in 20 years or when all the patents expire you can pick and choose
12:28 PM roycroft: in 20 years there will only be one corporation and it will own everything
12:29 PM LeelooMinai: I guess if you are money-oriented and lived in some capitalist country, you can think that way...
12:29 PM CaptHindsight: thats 3-5 presidents from now
12:29 PM gregcnc: how many ground breaking technologies are given away?
12:30 PM gregcnc: and then actually used for something
12:30 PM Loetmichel_: gregcnc: none. as far as i know
12:30 PM LeelooMinai: But I would say that engineer's dream in other places would be creating technology that solves problems with hunger, enrgy, etc. and giving it to the whole world - buggering the patents.
12:30 PM roycroft: no, we'll still have president trump in a jar then
12:30 PM roycroft: er
12:30 PM roycroft: president trump's head in a jar
12:31 PM Loetmichel_: IF someone invents cold fusion for real... it will be not as easy to survive that invention without getting it out in public ASAP
12:31 PM Loetmichel_: so it cant be surpressed any more
12:31 PM IchGucksLive: hi
12:31 PM Loetmichel_: if you fail that move you'll probably die
12:31 PM Loetmichel_: fast
12:32 PM LeelooMinai: Right, killed by some oil company ninjia assasins:)
12:32 PM Loetmichel_: yeah
12:33 PM Loetmichel_: or water power
12:33 PM Loetmichel_: or solar ;)
12:33 PM Loetmichel_: or ven just some government that wants it as their own advantage over all other nations
12:33 PM CaptHindsight: what would solve more problems now are printers that combine more than one tech, like SLA with FDM, or SLS with inkjet or milling etc
12:36 PM IchGucksLive: CaptHindsight: CN is working on
12:37 PM * LeelooMinai opens random packages that arrived from China after months...
12:38 PM LeelooMinai: Small thrust bearings - interesting. No idea why I got them - probably from curiosity:)
12:38 PM CaptHindsight: roycroft: Costco? https://www.youtube.com/watch?v=Z8zNsUTWsOc
12:41 PM CaptHindsight: do you think that the Great App bubble will burst in the next few years?
12:42 PM FinboySlick: "I like money."
12:42 PM CaptHindsight: this years Computex was all about eh comeback of the laptop
12:42 PM CaptHindsight: but I don't see it
12:42 PM IchGucksLive: Loetmichel_: is there a Norm for that cases https://www.ewh-shop.de/index.php?cat=c87_Kunststoff-Schaltschraenke-schaltschrank-kunststoff.html
12:42 PM LeelooMinai: Hmm, neat - two nuts with grove + cage with balls, nothing really expensive there, but smooth.
12:42 PM IchGucksLive: Loetmichel_: the ones with the PMMA dors
12:43 PM CaptHindsight: FinboySlick: lots of great lines in that film
12:43 PM Loetmichel_: IchGucksLive: probably. No, surly. but no idea which one ;)
12:43 PM LeelooMinai: I guess if I need to design something that has a tiny turntable, those will work great.
12:44 PM Loetmichel_: CaptHindsight: looking at trump and puitin i would wager that our future is more like "idiocracy"
12:44 PM Loetmichel_: ... sadly
12:45 PM FinboySlick: CaptHindsight: Big fan of Mike Judge's work. I hope you've watched Silicon Valley.
12:45 PM LeelooMinai: I was marveling at those bearing, and boom, Trump - broght to Earth with a crashing sound:)
12:45 PM Loetmichel_: LeelooMinai: i made a few xxl "lazy susans" out of marine plywood. a star-shaped inrunner and a bunch of regular 608zz bearings
12:45 PM CaptHindsight: FinboySlick: it's funny, but lately it's just become painful for me to watch
12:46 PM Loetmichel_: on the star runner betwenne the sheets and 2 on the upper plate to center a bolt scewed into the lower one
12:46 PM LeelooMinai: BTW, that Eric son of his may be as stupid as his dad - I saw him saying on news about democrats "they are not even people":)
12:47 PM LeelooMinai: I mean he literally said that.
12:47 PM FinboySlick: CaptHindsight: I identify a lot with Gilfoyle
12:48 PM CaptHindsight: FinboySlick: last episodes "smart" refrigerator hacking was great
12:48 PM FinboySlick: CaptHindsight: I'm a few episodes behind.
12:51 PM LeelooMinai: Loetmichel_: But the bearings had radial load on them, right?
12:52 PM LeelooMinai: Those tiny ones I got are for axial load.
12:52 PM LeelooMinai: 608zz I think, those are the ones that skaters use, etc.
12:53 PM LeelooMinai: I probably have them somewhere - used tham for my CNC hood/enclosure.
12:53 PM CaptHindsight: FinboySlick: it's full of stereotypes but Jian-Yang really hits it on the head
12:54 PM FinboySlick: CaptHindsight: I like that they expanded his role too. Though I always liked his well timed prank calls.
12:54 PM CaptHindsight: the dynamic between Gilfoyle and Dinesh is great
12:54 PM FinboySlick: And the perpetual tragedy of Jared's life.
12:55 PM LeelooMinai: That's too geeky even for me:p
12:55 PM CaptHindsight: why I'm not in silicon valley
12:56 PM FinboySlick: LeelooMinai: hehe, it's a guilty pleasure.
12:56 PM CaptHindsight: it really is like most maker spaces only with VC's
12:57 PM roycroft: silicon valley is an interesting place to visit once in a while
12:57 PM roycroft: living there would drive me insane though
12:57 PM LeelooMinai: Yes, before it is replaced with "coal mining and fraking valley" :)
12:58 PM LeelooMinai: fracking*
12:58 PM CaptHindsight: I'm still amazed by the cluelessnes of some investors
12:59 PM CaptHindsight: who do they get their tech advice from?
12:59 PM roycroft: the internet
12:59 PM LeelooMinai: Trump University
01:01 PM CaptHindsight: anyone interested in a Matsuura 710V, I'm looking for something bigger and faster
01:01 PM CaptHindsight: needs spindle bearings
01:02 PM CaptHindsight: they just get warm at this point
01:02 PM * LeelooMinai googles it and thinks "Right, it's tiny"
01:03 PM nubcake_ is now known as nubcake
01:04 PM roycroft: i'd be interested for $500, delivered :)
01:05 PM * roycroft would need to pour a new slab in his garage to support it though
01:05 PM LeelooMinai: If teleportation would be a thing, I would teleport it directly to a scrap yard:p
01:05 PM nubcake: :'D
01:06 PM CaptHindsight: it will probably end up in the corner for a while
01:07 PM CaptHindsight: if i find a nice 10-20K rpm spindle for it, then it will stay
01:07 PM CaptHindsight: I used to see used heads on ebay, but not lately
01:08 PM LeelooMinai: Risky bussiness
01:08 PM LeelooMinai: May have runouts, wear, who knows what.
01:09 PM SpeedEvil: If teleportation was a thing, I would like to transport the iron atoms from my backyard into the form of a perfect machine tool.
01:10 PM LeelooMinai: If that was possible you would not need any machine tool:)
01:15 PM CaptHindsight: http://www.ebay.com/itm/Mori-Seiki-Lathe-SL-2B-big-bore-cnc-lathe-/182485822619 isn't Rolla in JT's backyard?
01:15 PM CaptHindsight: $3k ^^
01:15 PM SpeedEvil: Autoleveling bed: https://www.youtube.com/watch?v=3kWsRF7KdPA (not really, cesium tungstate solution)
01:16 PM SpeedEvil: (ridiculously heavy and can float some metals)
01:16 PM JT-Shop: Rolla is about 3 hours away from me
01:17 PM CaptHindsight: _methods: what do you prefer Mori vs Mazak for lathes?
01:18 PM LeelooMinai: SpeedEvil: "Hehe, it's kind of fun" <- definitelly in the "last words" category.
01:21 PM JT-Shop: after a couple of hours of charging the forklift had just enough juice to load the knee mill onto the trailer...
01:22 PM CaptHindsight: I went from electric to propane forklift. I really want both now.
01:23 PM CaptHindsight: http://www.ebay.com/itm/MAZAK-QUICK-TURN-8-CNC-LATHE-QT-8-FOR-PARTS-OR-REPAIR-/282486937927 $1k or best
01:24 PM _methods: i like mori myself
01:24 PM _methods: i can't stand mazatrol
01:24 PM _methods: just my opinion so you know how useful that is
01:25 PM CaptHindsight: it would get the LCNC treatment
01:25 PM _methods: ah in that case probably won't make much difference
01:25 PM CaptHindsight: I've fixed both before
01:25 PM _methods: they're both physically good machines
01:25 PM CaptHindsight: same sorts of issues
01:26 PM _methods: i think it's easier to get mori parts though
01:26 PM CaptHindsight: and not mechanical
01:26 PM CaptHindsight: always the controllers
01:27 PM CaptHindsight: like to find something with live tooling
01:27 PM roycroft: so what is likely wrong with this that will cost me a lot of money to repair?
01:27 PM roycroft: https://portland.craigslist.org/mlt/bfs/6165472155.html
01:28 PM roycroft: wheel bearings?
01:28 PM CaptHindsight: the motor
01:28 PM roycroft: motors are cheap, relatively
01:28 PM CaptHindsight: unless it was dropped not much else
01:29 PM roycroft: if it needs a $200 motor it's still a good deal
01:29 PM _methods: the bearings the bed rides on
01:29 PM roycroft: yeah, i guess those would be pricey too
01:29 PM roycroft: probably more than the grinding wheel bearings
01:30 PM CaptHindsight: I got a bag of new balls for $10
01:30 PM roycroft: but if i go check it out i should get a good sense of whether they're shot or not
01:30 PM roycroft: if the bed moves smoothly, easily, and quietly there's a good chance the bearings are fine
01:31 PM _methods: if the mag is dead that can be expensive too
01:33 PM FinboySlick: roycroft: The bed is on bearings? I'd have imagined more standard ways back then.
01:33 PM CaptHindsight: http://www.ebay.com/itm/Lot-of-95-Loose-Chrome-Steel-Solid-Diameter-Ball-Bearings-/282508513392
01:34 PM IchGucksLive: im off Gn8
01:35 PM archivist: I got some balls, I then measured to select which I would use to fix the pitch measuring machine
01:35 PM Loetmichel_: $me is making a mess around here... MAAAN how stupid can one be? yesterday i trow a desk lamp off my desk. whith a glass shade that shattered... picked it up, put it back on the desk, cleaned the floor... just now i was a bit fast around the corner and managed to spear my elbow on one of the remaining glass shards... maaan, that was a fight to get that bandaid to stick with all that blood
01:35 PM Loetmichel_: :-( (why always me?)
01:36 PM archivist: because clumsy
01:36 PM Loetmichel_: yeah, something like that i guess
01:38 PM archivist: I was out at a customers replacing a shattered window on Monday, no cuts :)
01:41 PM roycroft: archivist: do you mind discussing your technique to resilver clock faces et al.?
01:41 PM roycroft: i've seen procedures where one rubs with silver nitrate, then rubs with cream of tartar
01:42 PM roycroft: and i've seen procedures where one mixes silver nitrate, table salt, and cream of tartar together and applies the mix all at once
01:42 PM archivist: roycroft, we did something like that, just bought some ready mixed stuff
01:43 PM roycroft: and then the old technique of using silver arsenate, which i think i'll avoid :)
01:43 PM roycroft: so you used a one-step process
01:45 PM archivist: I usually left it to ex boss to do :)
01:46 PM archivist: this one https://www.cousinsuk.com/product/dial-silvering-powder
01:47 PM archivist: that does have a finishing powder but we may have used tartar from the local supermarket iirc
01:48 PM archivist: http://www.ebay.co.uk/itm/100g-Clock-Dial-Silvering-Powder-Free-Finishing-Powder-/370622469899
01:49 PM roycroft: i'm not sure i'll be silvering any brass any time soon
01:49 PM roycroft: i'd like the option though
01:51 PM archivist: not sure if it is actually a chemical battery and electroplate technique, never researched it
01:51 PM roycroft: it says it's rub on
01:51 PM roycroft: and it comes with "finishing powder"
01:51 PM roycroft: i'll assume the product is silver nitrate and the "finishin powder" is the potassium bitartrate
01:52 PM archivist: damp cloth/paper dab in powder, rub on
01:52 PM roycroft: yes
01:53 PM roycroft: i figured the cream of tartar is a "fixer" analagous to using fixer on photographic film/prints after developing
01:54 PM roycroft: i'm a little concerned about doing this on machinery badges
01:54 PM roycroft: even though i'll coat with laquer immediately after silvering, i have durability concerns
01:54 PM archivist: if the badges are brass it will be fine
01:54 PM roycroft: it's my intent to use brass
01:55 PM roycroft: and i might be happy with the look of the brass, but there may be occasions where i'd prefer a silver color instead
01:55 PM archivist: brass lacquered looks nice un silvered too
01:55 PM roycroft: yes
01:56 PM roycroft: also, i figure that since i'll be experimenting with etching and filling with wax anyway, learning how to silver would be a logical extension of the skills
01:56 PM archivist: restoration after elebenty billion years id not too hard
01:57 PM archivist: the deeper the better for wax filling
01:57 PM roycroft: yes, that is what i would guess is the case
01:58 PM roycroft: i'm going to get a sheet of brass, cut it up into little squares, and etch for increasing periods of time to determine what works best
01:59 PM archivist: remember to get your wet and dry grain consistent for nice finish
01:59 PM archivist: we put the chapter ring on a lathe to get it right
02:00 PM archivist: full sequence of dial repair but no hands getting in the way to show operations http://www.collection.archivist.info/searchv13.php?searchstr=pd+norfolk+dial
02:01 PM roycroft: i won't be doing round things at first
02:01 PM roycroft: but i'm thinking that for the badges, i'll save some of the brass material and use it to hold up a sanding block so i can get even pressure on the badges when prepping
02:01 PM archivist: we had wet and dry on glass for straight grain
02:01 PM archivist: or polish
02:02 PM roycroft: that works too
02:03 PM roycroft: i have a small surface plate that i picked up really cheap which i use for lapping/honing - it makes a nice surface for attaching wet and dry
02:07 PM archivist: one thing to test is paint/wax compatibility with lacquer
02:08 PM archivist: I have to redo the barber coleman label because of that
02:37 PM enleth: OK, I just had a very interesting 7i77 failure
02:39 PM enleth: the mill threw an axis following error all of sudden and stopped, but did not turn the spindle off (which is controlled by a latching relay, so it needs an off pulse), so I had to use a manual spindle stop switch
02:39 PM enleth: then I tried to jog the machine out of the stock, but it wouldn't budge
02:40 PM miss0r: success! Now the EDM is drilling away
02:40 PM enleth: then I noticed that moving the Z handwheel does not update the DRO
02:40 PM enleth: and finally, that the X handwheel is moving the DRO in both X and Y in sync, and the field I/O fault LED on the 7i77 is on
02:40 PM miss0r: :-/ that does not sound good
02:41 PM miss0r: That actualy sounds like you killed something or you have some noise you need to look at
02:41 PM enleth: I'll power cycle it, but first I'm looking for anything that might be useful for diagnostics
02:41 PM enleth: all the power LEDs on the 7i77 are on
02:42 PM enleth: and it certainly is doing *something*, as the X encoder is being read correctly
02:42 PM enleth: just reported as X and Y
02:42 PM miss0r: and you've had this working without changing anything in the meantime?
02:43 PM enleth: yep, crapped out in the middle of a cut that I run a dozen times before that
02:43 PM enleth: the only thing out of ordinary is that I crashed the Z axis into the stock earlier because I wasn't paying attention
02:44 PM miss0r: Just shooting questions from the hip here: any changes? left the controller box open? more air humidity? power surges you've noticed?
02:44 PM enleth: it obliterated the endmill and made a dent in the stock, but I don't expect it to have had any effect on the electrical part of the machine
02:45 PM enleth: one of the control boxes, the one with 7i77, is open all the time, for now
02:45 PM enleth: otherwise no interesting changes around
02:45 PM miss0r: is it possible that a drop of water or a small chip made its way into the box?
02:46 PM enleth: what's really weird is that there wasn't any fault message displayed in axis other than the following error
02:46 PM miss0r: also: do you have a schematic of what you have build? that way I can be ALOT more helpfull in my questioning
02:46 PM enleth: normally, when I cut the field power while linuxcnc is still running, it spews a bunch of angry messages
02:46 PM miss0r: which, unfortunatly, is bad new
02:47 PM enleth: I have the original schematic of this mill, 7i77 is basically dropped in place of the old Heidenhain control
02:47 PM miss0r: When you cut the power, alot of questions are left unanswered. But when the electronics is crazy, it can answer random stuff that might fall 'within acceptable'.
02:48 PM enleth: well, I'm probably going to do a power cycle now
02:48 PM enleth: nothing interesting in dmesg, too
02:48 PM miss0r: Yeah. if that doesn't fix it. it smells a bit like a dead 7i77
02:48 PM enleth: oh, I can run PNCConf and see if it detects the 7i77
02:49 PM miss0r: I wonder if theres a diagnostic software for the 7i77

02:54 PM CaptHindsight: we have some similar with internal cavities
02:55 PM CaptHindsight: some have ports only .5mm dia that twist through the body
02:55 PM miss0r: enleth: any news?
02:55 PM enleth: still displaying a fault after a power cycle
02:56 PM miss0r: Can you take a picture of the board powered up? also how it is mounted in the box - just to give me some sort of idea
02:59 PM enleth: http://i.imgur.com/HHxE5ux.jpg - shitty phone photo, I can take a better one later
02:59 PM enleth: all four yellow supply LEDs are on
03:00 PM miss0r: I see chips!
03:00 PM enleth: must be some old stuff, I haven't been cutting aluminum for a while
03:01 PM miss0r: Does it have its own powersupply, by any chance? Have you measured the voltage on the input of the board?
03:02 PM enleth: it's getting regulated 24V from the machine's original built-in power supply
03:02 PM enleth: transformer, bridge, some old high power linear regulator
03:02 PM miss0r: Have you measured it on the input of the board right now? :]
03:02 PM enleth: yes, it's 24V
03:02 PM miss0r: alright
03:02 PM miss0r: Do you have a scope?
03:03 PM enleth: yep
03:03 PM miss0r: That supply is where I would start. does it have alot of ripples'n such?
03:03 PM enleth: to be honest, I'd be more interested in knowing what is considered a "fault" by the 7i77 field IO controller
03:04 PM miss0r: Can't help you there, sorry :]
03:05 PM enleth: I presume it's either that this LED is on by default and is turned off by the dsPIC in there as soon as it boots up
03:05 PM enleth: or maybe it can actually detect some kinds of failures
03:05 PM miss0r: and for some reason it isn't booting up the way it should ? sounds likely
03:06 PM enleth: tl;dr it would be nice if I could just replace a fried generic chip or two
03:06 PM enleth: less nice if the dsPIC is dead
03:06 PM enleth: I don't expect pcw_home to agree to send me just a programmed chip to solder in on my own
03:07 PM miss0r: I would consider doing an idiot clean-up.. Just detacting the board, and removing it completely from the enclosure and blast it with a mix of air and electronics cleaner agent
03:07 PM miss0r: I think you are correct about that :]
03:08 PM enleth: that's the next step after cold booting the PC with 6i25
03:09 PM miss0r: In the meantime, might I entertain you guys with a short video of my EDM doing its first drilling automatically: https://drive.google.com/open?id=0B51cA8Udo5i7RlNsRTBBVUJfVzA
03:14 PM CaptHindsight: https://imagebin.ca/v/3PBiRswEt0y5 which one will win the positionong wars?
03:26 PM enleth: OK, there wasn't any visible contamination on it but I gave it a couple blasts of compressed air, then connected the DB25 cable to 6i25 and powered up the field IO part with 24V from a lab supply, everything else disconnected
03:26 PM enleth: still displaying a fault
03:27 PM DaViruz: miss0r: wire edm? or plunge?
03:27 PM enleth: pcw_home: are there any further debugging steps to be taken with a 7i77 that developed a sudden field IO fault and keeps faulting even out of the machine, powered up with a known good supply?
03:29 PM enleth: pcw_home: what does that LED actually *mean*? what controls it, what triggers it?
03:29 PM enleth: the field IO fault LED, that is
03:29 PM enleth: hm, wait
03:30 PM enleth: I should have read to the end of the manual page before asking - it's a host comms watchdog fault
03:32 PM miss0r: DaViruz: plunge
03:33 PM miss0r: enleth: Sounds like the 7i77 is dead
03:35 PM enleth: miss0r: well, technically speaking, it might be something else
03:35 PM enleth: if that LED is a watchdog fault, maybe it's the opto
03:36 PM miss0r: That is true. How come they are so secretive about what it means!
03:37 PM sync: just ask pcw_home
03:38 PM enleth: miss0r: honestly, I've got enough of a problem possibly having to replace an $200 part for no good reason, no need to throw irony at me for something I already admitted
03:38 PM enleth: besides, I don't know if a watchdog fault is the *only* thing that triggers this LED
03:39 PM JT-Shop: the DS3231 has arrived
03:40 PM phipli: now you can tell the time
03:41 PM phipli: I've not used a DS3231 I don't think - mainly used DS1307s in the past
03:42 PM enleth: interesting - mesaflash --sserial does detect the field IO part
03:42 PM enleth: as long as it's getting power
03:42 PM phipli: One thing handy with some RTCs is that they have spare EEPROM that you can use for other things
03:43 PM enleth: pcw_home: OK, the question still stands - what are the possible meanings of the field I/O fault LED other than host comms watchdog, or why would the watchdog fault if there is *some* sort of communication going on, with the field IO being detected by mesaflash?
03:43 PM JT-Shop: now I need to figure out how to connect it up, it has 5 wires
03:43 PM JT-Shop: but first I need to unload the mill
03:45 PM miss0r: enleth: Didn't try to throw anything at you realy
03:45 PM JT-Shop: page 19 of the 7i77 manual describes the led meanings
03:46 PM enleth: JT-Shop: yes, I noticed that, but what I see is somewhat inconsistent with that description and I included this fact in the question
03:47 PM enleth: JT-Shop: it can't be *just* a host comms watchdog, because I am getting host communication with the field IO
03:49 PM enleth: by that I presume the dsPIC on the field IO side is booted up and responding
03:49 PM pcw_home_ is now known as pcw_home
03:50 PM enleth: *something* is returning valid sserial discovery data over that opto and there isn't really anything else on that side of the board that could do that, as far as I can remember
03:50 PM enleth: so it can't be only a watchdog indicator, or it's not just a dumb watchdog
03:59 PM XXCoder: sync: yeah though luckly it lasts pretty long time.
04:02 PM McBride36 is now known as McAFK

04:30 PM roycroft: drink lots of beer
04:30 PM roycroft: aim for bucket
04:30 PM roycroft: free coolant
04:31 PM XXCoder: add distalled water to your remaining stock
04:31 PM XXCoder: good enough till you get more
04:31 PM gregcnc: if i had some to begin with i wouldn't be so worried
04:31 PM XXCoder: doh
04:31 PM XXCoder: time to work later
04:35 PM CaptHindsight: gregcnc: homuch dusyah need?
04:37 PM gregcnc: a pail would make up a sumps worth sump
04:37 PM roycroft: would some of that pet-friendly car anti-freeze work?
04:38 PM roycroft: it's supposed to be a lot less corrosive than the regular stuff
04:38 PM gregcnc: what i've found out is cutting fuids are highly engineered except for teh cheapest stuff
04:38 PM roycroft: yes
04:38 PM roycroft: but you're in a pinch
04:38 PM roycroft: i'm talking about get through the day stuff
04:38 PM CaptHindsight: ethylene or methylene glycol?
04:39 PM gregcnc: I saw propylene glycol based made in canuckistan
04:39 PM JT-Shop: mill inside and door is down, break time

04:43 PM gregcnc: I wanted to get some trim 690XT or Qualichem 250C
04:43 PM gregcnc: but that sounds very similar
04:43 PM gregcnc: where did you buy it?
04:44 PM CaptHindsight: I got 5gal with a machine
04:45 PM CaptHindsight: makes like 55gal
04:46 PM CaptHindsight: https://www.mscdirect.com/product/details/36206423 should be next day ground
04:48 PM gregcnc: 3 days
04:49 PM gregcnc: but probably what i end up doing
04:50 PM CaptHindsight: just checked, yeah in Ga vs Indiana
04:50 PM CaptHindsight: :(
04:50 PM gregcnc: how did you see that? i called to find out
04:50 PM CaptHindsight: put it in the cart and started checking it out
04:51 PM CaptHindsight: it usually tells me what location they are in stock before it goes into the cart
04:51 PM CaptHindsight: not cutting fluids for some reason
04:52 PM gregcnc: they told me OH has it but it was the longest delivery?
04:52 PM CaptHindsight: huh Ohio is usually 1-2 days
04:52 PM roycroft: speaking of putting things in carts
04:52 PM roycroft: amazon jerked me around again
04:52 PM roycroft: i went to order something
04:53 PM dioz: funds unavailable
04:53 PM roycroft: when i went to check out i got an error saying one of the items was only available to prime members and that i would have to pay for prime to be allowed to buy it
04:53 PM CaptHindsight: I don't trust Amazon any more than any deal made in China. It's not a deal until it's all over.
04:53 PM roycroft: so i deleted it from my cart
04:53 PM roycroft: went back
04:53 PM roycroft: added it again
04:53 PM roycroft: and was able to complete checking out
04:54 PM roycroft: this is twice in a week they've jerked me around trying to force me to sign up for prime
04:54 PM CaptHindsight: everything is dynamic
04:54 PM CaptHindsight: price, delivery, availability
04:54 PM roycroft: yes
04:54 PM roycroft: i trust them after they post a tracking number
04:54 PM roycroft: but not until then
04:54 PM CaptHindsight: I don't buy anything on Amazon that I need urgently
04:54 PM roycroft: nor i
04:54 PM dioz: given how you react to amazon. i'd assume you'd also think united airlines was wrong with how they dealt w/ that doctor
04:54 PM CaptHindsight: like ebay
04:55 PM dioz: amirite?
04:55 PM roycroft: which is why i'll never sign up for prime
04:55 PM CaptHindsight: I'm happy if it shows up
04:55 PM CaptHindsight: and it's sually easy to return
04:55 PM roycroft: i think it should be illegal for airlines to overbook flights
04:55 PM dioz: why?
04:56 PM CaptHindsight: you know why it's leagal for them to do that?
04:56 PM roycroft: because they have total control over their passengers
04:56 PM LeelooMinai: Anyone knows how much are auto-darkening welding helmets sensitive? I mean if I shine strong flashlight on it, it should darken?
04:56 PM gregcnc: last time i ordered amazon w free shipping they waited until the last day to ship for arrival on the last delivery day.
04:56 PM CaptHindsight: fuck you! that's why :)
04:56 PM roycroft: it's almost a monopoly
04:56 PM toner: if they do overbook, they need to handle capacity issues at the boarding desk
04:56 PM toner: once you're seated, you should be good to go
04:56 PM roycroft: they used to, toner
04:56 PM dioz: operational situations arrise. there needs to be, sometimes, deviations. it's outlined in their usage policy
04:56 PM dioz: same w/ cellphones
04:56 PM roycroft: and i used to not take the attitude that it should be illegal
04:57 PM dioz: cellphones aren't guaranteed to work
04:57 PM roycroft: that's different than overbooking, dioz
04:57 PM dioz: not really
04:57 PM roycroft: yes, really
04:57 PM CaptHindsight: you just don't matter
04:57 PM CaptHindsight: silly person
04:57 PM dioz: there's operational aspects that come up preventing normal operation
04:57 PM roycroft: i don't fly
04:57 PM dioz: shit happens
04:57 PM roycroft: that's my solution:)
04:57 PM toner: I don't think there should be a law preventing them from removing passengers in that case, but it should be a PR shitstorm when they do :P
04:57 PM roycroft: the last time i flew was a week before 9/11
04:57 PM LeelooMinai: Hmm, maybe I need to leave it on the sun or something to charge.
04:57 PM CaptHindsight: most people just don't care
04:58 PM roycroft: i refuse to play the security theatre drama game
04:58 PM roycroft: i rarely left my timezone anyway
04:58 PM roycroft: but since 9/11 i've traveled on amtrak and i've driven
04:58 PM CaptHindsight: they would stand in line to get shot in the head and fight for positions in front
04:58 PM roycroft: i'm done with the airline industry
04:58 PM dioz: i think to say that this business HAS to treat you a certain way is noy very capitalistic. that's the cry-baby affect imo
04:58 PM dioz: entitlement
04:58 PM roycroft: capthingsight: it might be obvious by now that i'm not the typical consumer
04:59 PM roycroft: it's not a capitalistic industry
04:59 PM roycroft: it's a de facto monopoly
04:59 PM roycroft: market forces do not apply
04:59 PM roycroft: which is why regulation and oversight are required
05:02 PM dioz: so even less hard to grasp the concept of the idea that it is a luxury. it isn't a right to fly
05:02 PM Jeebiss_ is now known as Jeebiss
05:02 PM dioz: you don't have the right to board their aircraft
05:02 PM roycroft: luxury is not the opposite of a right
05:02 PM CaptHindsight: roycroft: it tends to be easier when outside the US except when traveling back into the US
05:02 PM roycroft: it's become easier to not want to travel back to the us lately :)
05:02 PM dioz: it is a service they sell with certain terms and conditions
05:02 PM CaptHindsight: I got pulled out of line with my kids for rolling my eyes in Tokyo when I saw the BS
05:02 PM dioz: those terms abd conditions are outlined
05:02 PM LeelooMinai: dioz: Be careful what you wish for imo:)
05:02 PM dioz: if you don't like it don't interact with the company
05:02 PM roycroft: dioz: as i said earlier
05:02 PM dioz: or cry abouy it i guess
05:02 PM roycroft: i refuse to play the security theatre drama game
05:02 PM roycroft: and i'm not crying
05:02 PM dioz: you must be a liberal
05:02 PM roycroft: i am what i am
05:02 PM roycroft: i don't fit in any of your boxes easily, i suspect
05:02 PM roycroft: sorry
05:02 PM dioz: well if you're suggesting a business should be obligated to operate in such a manner...
05:02 PM roycroft: and that was not a canadian sorry
05:02 PM roycroft: it was a sarcastic sorry
05:02 PM roycroft: i have a grasp of remedial economics
05:03 PM roycroft: you obviously do not
05:03 PM {HD}_ is now known as {HD}
05:03 PM LeelooMinai: I once took a questionare that would put your positions into an area in four quadrants - I ended up close to the dot maked "Ghandi":p
05:03 PM dioz: hah. sure if enough people don't agree with such operational policy the business has a chance of losing customers
05:03 PM roycroft: it's a fairly essential service that operates as a de facto monopoly
05:03 PM dioz: but the fact you're suggesting a business should be obligated in such a political eay...
05:03 PM dioz: way
05:03 PM dioz: that is very odd
05:03 PM roycroft: i'm not suggesting anything political
05:04 PM roycroft: i'm stating reality
05:04 PM roycroft: airlines are not capitalistic
05:04 PM roycroft: they are monopolistic
05:04 PM dioz: legal ramifications for not obliging would involve politics and policies
05:04 PM roycroft: free market rules do not apply
05:04 PM roycroft: that's economics, not politics
05:04 PM roycroft: the supply/demand curve does not apply
05:04 PM CaptHindsight: get people to care again
05:04 PM LeelooMinai: dioz: You think liberal = wrong?
05:05 PM dioz: LeelooMinai: i think liberals are very confused atm.
05:05 PM CaptHindsight: who stops them?
05:05 PM roycroft: i'm not confused at all
05:05 PM roycroft: but i'm also not going to adopt the label you're trying to plaster on me
05:06 PM dioz: the same liberals talking about equality and inequity are hoping their governments develop strong economies yet the very aspect of a atrong economy involves crushing (financially) other states.. which promotes inequality
05:06 PM dioz: neoliberalism isn't a good thing
05:06 PM LeelooMinai: dioz: So according to you what - everything should be run by private companies and no services should be provided by government or what?
05:06 PM CaptHindsight: roycroft: ignore the trolls
05:07 PM * roycroft will continue not flying, and will exercise his first amendment right to vocally state that he believes airlines should be regulated
05:07 PM roycroft: and that's all i have to say on the matter
05:07 PM dioz: i could also point out all the issues with democracy
05:08 PM dioz: but the usa is a constitutionalaly representative republic
05:08 PM CaptHindsight: how much should one spend on a chuck key?
05:09 PM dioz: make your own
05:09 PM roycroft: lathe chuck or drill chuck?
05:09 PM CaptHindsight: shoulkd I splurge on the chrome plated version at $65 or?
05:09 PM roycroft: no
05:09 PM CaptHindsight: lathe
05:09 PM roycroft: a lathe chuck key should cost no more than $20, unless it's a really big chuck
05:09 PM gregcnc: mine was painted blue and straight at one point in time
05:12 PM CaptHindsight: I gave mine away with the lathes I sold
05:12 PM roycroft: it's not hard to make one
05:12 PM roycroft: i would never pay $65 for a chuck key
05:12 PM roycroft: and i would not ever want a chrome plated one
05:12 PM roycroft: i'd be afraid to use it
05:12 PM roycroft: teh shiny might go away
05:14 PM roycroft: my lathe did not come with a chuck key
05:14 PM dioz: LeelooMinai: i'm not a big fan of things like... government provided health care or employment insurance or welfare
05:14 PM roycroft: a 3/8" socket extension worked fine though
05:15 PM roycroft: then i bought a 3/8" square chuck key
05:15 PM roycroft: then i bought a 4 jaw
05:15 PM roycroft: and it came with a 3/8" chuck key
05:15 PM roycroft: but that's ok - now i have two
05:15 PM roycroft: and i can do the dual-handed 4 jaw centering thing
05:15 PM roycroft: loosen one side while tightening the other
05:16 PM * JT-Shop likes a 4 jaw chuck better
05:16 PM roycroft: you're also not a big fan of respecting other people's opinions/feelings, apparently, dioz
05:16 PM LeelooMinai: dioz: Very interesting. Disastrous probably, but ok - I guess it's a plan.
05:16 PM CaptHindsight: JT-Shop: what about for round stuff?
05:16 PM dioz: roycroft: you can have whatever opinion you want and i'll fight for your right to have it
05:16 PM roycroft: a 4 jaw is more accurate than most 3 jaws
05:17 PM JT-Shop: for all stuff, you can center up a piece much better in a 4 jaw
05:17 PM CaptHindsight: roycroft: had to read the logs to see who was trolling you
05:17 PM roycroft: well, some 3 jaw scroll chucks have those adjusters
05:17 PM roycroft: they're effectively 3 jaws encapsulated in 4 jaws
05:17 PM dioz: LeelooMinai: how is it disasterous? i'd say what is more disasterous is allowing people who haven't contributed to the federal safety nets use them is more disasterous.
05:17 PM roycroft: but they're also rather expensive
05:18 PM CaptHindsight: ChinaCo 4-jaws are just as bad as the 3-jaw :)
05:18 PM JT-Shop: I use polish chucks
05:18 PM roycroft: the 4 jaw i just bought is a cheap import
05:18 PM roycroft: i expect it will get me by for a while
05:18 PM roycroft: i expect it will be rather fiddly, but i'll be able to make accurate parts with it
05:19 PM dioz: when does a state become so over-run with non-contributers?
05:19 PM roycroft: in most cases, the machine operator is the determinant of the quality of the parts, not the machine
05:19 PM CaptHindsight: I avoid any Chinese tools or tooling now. Just not worth the time lost
05:19 PM roycroft: i don't make a living machining
05:19 PM CaptHindsight: unless it's really crude work
05:19 PM roycroft: and i'm trying to refine my skills
05:19 PM roycroft: the imported stuff is fine for me for now, for most things
05:20 PM CaptHindsight: hmm do I use a chisel or mill this part?
05:20 PM roycroft: when one is bootstrapping one's machine shop, buying top end stuff from the get-go is not usually possible
05:20 PM CaptHindsight: keep an eye out for old good stuff
05:20 PM CaptHindsight: it tkaes some time
05:20 PM roycroft: the thing is though, i have a good sense of the limitations of my stuff and the compromises that i'm making, and set my expectations accordingly
05:20 PM roycroft: yes
05:21 PM LeelooMinai: dioz: I am just saying that's ok, it's a strategy. I guess "only strong should survive" kind of strategy. I guess in Star Wars universe you would be on the Sith side:p
05:21 PM roycroft: but i'm not going to wait the rest of my life to acquire tooling/fixtures/etc.
05:21 PM dioz: i think the existing ideas of altruism and pity and kindness and sympathy are a result of judeo-christian indoctrination... when in fact evolution isn't the rsult of being nice. it's the result of winning
05:21 PM roycroft: this is a good strategy for me
05:21 PM roycroft: let the two people who like to troll me troll each other
05:21 PM roycroft: and i'll stay out of it :)
05:22 PM roycroft: capthindsight: there are certain things on which i won't compromise, because they just don't work at all
05:22 PM LeelooMinai: I am starting wondering if republicans = Sith/Orcs/etc. and libeerals are like Jedi/Human/Elfs in sci-fi/fantasy... It would expleint a lot to me in politics:)
05:23 PM dioz: hah. that'd an egotistical eay of viewing it i guess
05:23 PM phipli: excellent - my mill isn't completely dead
05:23 PM phipli: it was just... more intermittent than it was before
05:23 PM dioz: i'mma go on a limb and say you think morality is universal as well
05:23 PM roycroft: telescoping gages, for example
05:23 PM roycroft: i did not have a set for a long time, because every chinese import set i used was so sticky it was impossible to set them
05:24 PM * phipli goes looking on the internet for replacement mosfets...
05:24 PM roycroft: i finally got a mitutoyo set at a garage sale a few years ago
05:24 PM roycroft: and they actually work
05:24 PM LeelooMinai: I did not say that one side is better than the other:) I guess one will be attracted to one of them more, and what are you going to do:/
05:25 PM dioz: LeelooMinai: i'd almost believe that... i think it's indoctrination. i find about 100% of liberals suffer from sever cognitive diaonance
05:26 PM andypugh: CaptHindsight: I made my own slightly special chuck-key to suit all my chucks. https://goo.gl/photos/dUpckqfB8EXqrYMa8
05:26 PM * roycroft thinks two people need to go to #politics and leave this place
05:27 PM CaptHindsight: andypugh: nice color shifting finish as well :)
05:27 PM * LeelooMinai thinks roycroft started it and now tries to blame late-comers:)
05:27 PM roycroft: you must have seen a universal tyre iron before :)
05:27 PM dioz: i think people who comment on other people chats and complain are kind of babies
05:27 PM dioz: "i don't like your chats"
05:27 PM CaptHindsight: good thing that 3/8 socket extensions fit the chucks
05:28 PM andypugh: CaptHindsight: I hardened and tempered the ends, I used silver-steel (caution, does not contain silver)
05:28 PM dioz: we all just here to exchange ideas and further our understanding. i thi k it's sad people would rather walk around with their fingers in their ears
05:28 PM roycroft: you can get a good grip on that
05:28 PM dioz: i'm done though
05:28 PM roycroft: and it won't hurt to pull on it
05:29 PM roycroft: i like that - the ones i have are the typical ones with the thin rods to spin the wrench
05:29 PM roycroft: i need to fix that - even putting some padding on them would help
05:33 PM LeelooMinai: lol: "DIY Rahn Repeat-O-Meter Part 1: CAD Design" - https://www.youtube.com/watch?v=ra727zZCMzk
05:33 PM roycroft: i have to say, a 4 jaw would have been nice for putting my spindle nose replica back in the lathe yesterday
05:33 PM LeelooMinai: I thought it was a joke - sounds like something one would see being sold on a shopping channel
05:33 PM roycroft: i never did get it to run completely concentrically again
05:34 PM roycroft: although i must say, when i blued it at the end and screwed the chuck on it, the register bluing was evenly worn away all the way around
05:34 PM roycroft: so i guess i got that part round
05:35 PM roycroft: the threads were a little messy, though
05:35 PM dioz: isn't the biggest difference from 3 to 4 jaw just how accurate you can align?
05:36 PM dioz: you guys watch the youtube vid of the guy lathing rebar?
05:36 PM roycroft: i spent about a half hour trying to get the thing to run true when i chucked it up again, and finally gave up
05:36 PM CaptHindsight: I'd like to find a source for square machine bases to mount linear bearings to for cartesian setups
05:36 PM roycroft: you can get surface plates for a song
05:37 PM roycroft: they're pretty square and pretty flat
05:37 PM CaptHindsight: from ~3'x 3' to 5' x 10'
05:37 PM LeelooMinai: lol
05:37 PM roycroft: surface plates that big would require at least a whole symphony
05:37 PM roycroft: a mere song won't quite do it
05:38 PM LeelooMinai: CaptHindsight: You may need some "music wire" tricks maybe:)
05:38 PM CaptHindsight: I can get an entire router for $5k but it's not square
05:39 PM LeelooMinai: CaptHindsight: Did you see that paper I once linked about my idea that seems to be already tested by someone?
05:39 PM CaptHindsight: http://www.ebay.com/itm/JCUT-1530B-5x10-CNCwoodworking-machine-cnc-router-freeship-ON-SALE-/132178178296
05:39 PM LeelooMinai: CaptHindsight: You can measure this way close to 1-2microns on long distances - I mean measure for straightness, with low cost parts really.
05:40 PM CaptHindsight: they just make them so wrong
05:40 PM CaptHindsight: trapezoid vs rectangle
05:49 PM LeelooMinai: BTW, there's 30 minute response video from oxtools guy after that Rahn NY CNC one.
05:49 PM LeelooMinai: Kind of interesting.
05:49 PM dioz: link
05:50 PM LeelooMinai: https://www.youtube.com/watch?v=ZkCIVsP7-KY
05:50 PM Cromaglious_: I left a note on Tom's about differential screw adjusters
05:54 PM sync: I don't really like both designs
05:54 PM sync: the original one with the sharp edge in the flexure is dumb and toms design is too much effort imho
05:55 PM sync: a hole drilled and then bandsawed into the side would do
05:56 PM LeelooMinai: Hmm, right, hole makes sense - easier to make very accurate one, and well, it does not have any sharp transitions.
05:57 PM sync: the hole dimension is not relevant
05:57 PM sync: surface finish more so. but in that case also not really relevant
05:57 PM LeelooMinai: Dimension no but consistency probably desirable.
05:58 PM LeelooMinai: I guess one really wants that hole to be parallel to the edge.
05:58 PM LeelooMinai: So you don't get changes in thickness on the hinging area.
05:59 PM sync: as long as it is within reasonable tolerance it'll do
06:00 PM LeelooMinai: Ok, time to go outside and see if my welding helmet charged itself on the sun:)
06:05 PM LeelooMinai: O, I see. It works now, but I cannot trigger it with even strong focused LED flashlight. Sun does trigger it though.
06:11 PM dioz: how do i make sure my taps are straight?
06:11 PM dioz: in 1/4in plate
06:11 PM gregcnc: do the tapping before the 24 pack
06:12 PM dioz: dough!
06:13 PM dioz: i countersunk some holes but it looks like my tap in the receiving plate don't line up.
06:13 PM dioz: so the flat top screws sit a little fucky
06:13 PM LeelooMinai: dioz: When I was tapping plates for my CNC I used a press drill and a tool you can put in it that holds a tap.
06:13 PM TurBoss: hello
06:14 PM dioz: how'd you control your feed?
06:14 PM TurBoss: is NativeCam a deb package?
06:14 PM LeelooMinai: Well, it's a press drill - you have control over the feed + the tool has spring inside that allows for some movement.
06:14 PM TurBoss: or I still need to do the nondeb install?
06:15 PM LeelooMinai: dioz: Same like this one, apparently called tapguide (cheap but very useful): https://d3d71ba2asa5oz.cloudfront.net/32001291/images/tapguide.jpg
06:16 PM gregcnc: flat head screws are unforgiving with hole position
06:16 PM LeelooMinai: You put the back into the chuck, and the sharo cone goes into your tap holder.
06:17 PM LeelooMinai: Ins if you first use center punch in the chuck to center it to the hole, you will get pretty accurate tapping.
06:18 PM LeelooMinai: Ins=And
06:18 PM LeelooMinai: covfefe
06:19 PM LeelooMinai: Damn, thouse welding magnets are strong - just lifted my steel table top with a lot of stuff on it with one.
06:23 PM andypugh: If you have a lot of tapping to do: https://www.grizzly.com/products/G8748
06:23 PM andypugh: (or similar, possibly home-made)
06:24 PM JT-Shop: I have a tapmatic tapping head for the Enco, I need to sell it...
06:25 PM andypugh: TurBoss: I think that NCam _will_ be a deb package, but isn’t yet.
06:25 PM TurBoss: thanks
06:26 PM LeelooMinai: Well, on the git site the guy writes that should be in the package soon, but he writes that for weeks now:)
06:32 PM dioz: andypugh: that looks decent
06:33 PM JT-Shop: Tom_L: are you going to log the ##chickens channel?
06:36 PM dioz: TurBoss: packages.debian.org
06:37 PM JT-Shop: say goodnight Gracie
07:07 PM Tom_L: JT-Shop, was that a request or a question?
07:08 PM Tom_L: looks pretty empty to me
07:20 PM LeelooMinai: mm, weird, the oxtools guy says that the feet on that tool should be harder than granite. My first thought would be softer, so they don't damage the plate.
07:25 PM LeelooMinai: If I had to do those feet, I would use ceramic bearing balls, make pits for them in the plate and glue them in with some magic glue.
07:26 PM LeelooMinai: Not sure why he flattened his steel balls.
07:26 PM LeelooMinai: I would think that having round legs would be ok.
07:26 PM LeelooMinai: Stands/feet that is.
08:57 PM CaptHindsight: how do you use that Grizzly hand tapping machine in the middle of a 24" wide plate?
08:58 PM CaptHindsight: only hgolds parts up to 6" wide
09:01 PM * LeelooMinai imagies CaptHindsight on a set of "Captain Obvious, Part II - The Second Part"
09:03 PM SpeedEvil: CaptHindsight: simply saw out a channel to within 18" so it will fit, then weld it back up
09:05 PM CaptHindsight: good thinking, I was going to tap a bunch of holes in small circular pieces and then drill and weld them in place
09:14 PM LeelooMinai: Damn, I need some channel with people that use Fusion 360:/
09:15 PM LeelooMinai: Hmm, what people on freenode actualy CAD, let me se...
09:18 PM LeelooMinai: Hmm, wonder what @librecad is and if they will kill me if I mention Fusion
09:18 PM LeelooMinai: Right, it's some opern source project - not a good idea I guess:)
09:20 PM malcom2073: Freenode is an open source network fwiw
09:20 PM malcom2073: Hence the "free" part of it
09:20 PM malcom2073: There used to be a solidworks channel, but as you would expect, it's pretty much dead
09:20 PM TurBoss: try at propierarynode
09:21 PM TurBoss: :)
09:22 PM LeelooMinai: I am evil:) http://i.imgur.com/3NZSMax.png
09:22 PM malcom2073: Trolling isn't evil, just... young.
09:22 PM TurBoss: hohohoho
09:23 PM TurBoss: gn8
09:23 PM LeelooMinai: Trolling is a tool - you can fish with it:p
09:25 PM LeelooMinai: Hmm, 2 people on #cad, including me - sad.
09:26 PM SpeedEvil: there is aslo ##engineering and ##mechanics
09:27 PM LeelooMinai: Those seem pretty broad - I wonder what people talk about there even.
09:33 PM SpeedEvil: low traffic alas
09:34 PM LeelooMinai: Low energy channel
09:51 PM dioz: trolling isn't young. it's intellectual
09:52 PM dioz: if, based on text, you feel your ideals or implicit biases are being pushed against how do you know it isn't ,infact, YOU with the problem?
09:53 PM dioz: if it's absolute nonsense you should be able to destroy the argument factually
09:55 PM dioz: and i think way too many use the words troll and spam wrong
09:55 PM dioz: spam is advertisements not "text i don't wanna see" and a troll is a hyper-negative person. not just someone who says something you disagree with
10:05 PM dioz: rain makes corn. corn makes wiskey. wiskey makes my baby, feel a little frisky
10:05 PM dioz: rain is a good thing
10:13 PM roycroft: capthindsight: the upright of that hand tapper is attached to the base with four bolts
10:14 PM roycroft: you can detach it from the base, drill and tap four holes in the middle of your plate, attach it to the plate, and then use it to tap your hole
10:15 PM LeelooMinai: I would make a long flat steel bar for it with holes to attach and then you can clamp the whole bar to any surface.
10:16 PM LeelooMinai: Maybe steel angle - so it's stiff.
10:36 PM Tom_L: there are Fusion users here
10:36 PM Tom_L: i'd suggest you go to librecad and ask though. you seem rather good at changing topics
10:37 PM LeelooMinai: Tom_L: Ok, how about you? All I see is you being good at is showing how dissatisfied you are with others:p
10:38 PM Tom_L: i don't use fusion.
10:38 PM LeelooMinai: I mean in general.
10:38 PM Tom_L: i use solidworks, smartcam, catia and a few others
10:39 PM Tom_L: i choose to be silent at times
10:39 PM CaptHindsight: roycroft: I ordered a box of holes from Alibaba
10:39 PM Tom_L: CaptHindsight on sale i hope
10:39 PM CaptHindsight: it would be stupid to pay full price
10:40 PM LeelooMinai: I have seen one of those in cartoons - you put a hole on a wall or whatever and you go through, then take the hole back.
10:40 PM * Tom_L wishes this channel had one
10:41 PM roycroft: i hope you got free shipping, capthindsight
10:43 PM CaptHindsight: roycroft: these were the clear holes, they showed me a pic and you could see right through them
10:44 PM CaptHindsight: whole box like they weren't even there
10:44 PM Tom_L: like donut holes?
10:44 PM CaptHindsight: yeah but the hole part not the clump that comes out of the hole
10:45 PM LeelooMinai: Chinese wormholes - they lead to Norh Korea leader bedroom.
10:46 PM CaptHindsight: they should call donut holes plugs
10:46 PM Tom_L: the real question is, are they donuts or doughnuts ?
10:47 PM CaptHindsight: I donot know
10:48 PM LeelooMinai: It happens, I am just making holes too; for my new "reinforcements" on rails: http://i.imgur.com/G2IvSk5.png
10:48 PM LeelooMinai: Added those angles there on all rails, to make them more stiff.
10:49 PM LeelooMinai: If this somehow bends, then I will be very surprised...
10:51 PM LeelooMinai: Hmm, I should probably just use steel tubes from the start, but, I was not really sure how to attach steel tubes to angles on the ends, etc.
10:51 PM LeelooMinai: Sans welding.
10:52 PM Tom_L: i'd suggest if you have specific questions about Fusion, you ask. there are those here that use it
10:52 PM LeelooMinai: A, I figured it out already - could not find the ant-alias option. Somehow it's not in graphics preferences, but in other place (Display options).
10:53 PM LeelooMinai: anti-alias*
10:54 PM LeelooMinai: In the past I was using pirated SolidEdge - was nice, but it's a monstrous software in comparison to Fusion360

10:59 PM Tom_L: as a first time problem, that was a fun one
11:00 PM LeelooMinai: CATIA is what? CAD or some simulation?
11:00 PM Tom_L: all the above
11:01 PM LeelooMinai: What is this, a children slide? :)
11:01 PM Tom_L: it and solidworks are cousins
11:01 PM Tom_L: unknown
11:01 PM Tom_L: but no
11:02 PM Tom_L: an aircraft part
11:02 PM LeelooMinai: Loft over path and done?
11:02 PM Tom_L: i did all those in the directory both in solidworks and catia
11:03 PM Tom_L: and around 100 more
11:03 PM LeelooMinai: I guess in Fusion360 I would use something they call it here "sweep"
11:03 PM Tom_L: 10 were required to pass
11:04 PM Tom_L: there are 2 compound curves in that part
11:04 PM LeelooMinai: Right, but it's still a path - just not on a plane.
11:04 PM Tom_L: it may appear flat in the pic, but it isn't
11:05 PM LeelooMinai: No, I can see that it's curved on two planes.

11:09 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/x_problem106.jpg
11:12 PM LeelooMinai: Hmm... That middle part is a bit tricky I guess. Fusion360 has "sculpture" mode where you can work with faces, more like in Blender, so maybe it could be modelled as flat and then bent there. Did not really do anything in that sculpt mode yet.
11:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/Problem52.jpg
11:34 PM Tom_L: that was a fun one
11:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/Problem45.jpg
11:34 PM Tom_L: as was that
11:40 PM Tom_L: all were graded by part volume so every fillet etc had to be "right"
11:42 PM LeelooMinai: If you knew the volume you could just create a cube to troll the teacher:)
11:43 PM Tom_L: some of us knew the volume because we wanted to get it right
11:43 PM Tom_L: for example, if you did multi surface fillets in the wrong order it would come out different
11:44 PM Tom_L: choosing the fillet order was important
11:46 PM LeelooMinai: Right - looks like interesting and fun class
11:46 PM Tom_L: expensive
11:46 PM Tom_L: that was just the first of many on catia
11:47 PM Tom_L: like i said, i did all those in both catia and solidworks just for the heck of it
11:49 PM Tom_L: that was a while back..
11:52 PM Tom_L: catia has built in cam but i don't like it much
11:55 PM Tom_L: LeelooMinai, that part was actually easier than it looks. iirc i just did an offset plane for the tabs
11:56 PM Tom_L: i'd have to go back and look for sure but i think that's how i did it
11:57 PM LeelooMinai: I guess different CADs may have a bit different ways of modelling weird parts.
11:58 PM Tom_L: they are more similar than you realize
11:58 PM LeelooMinai: That CATIA interface looks a bit dated - like 90s-style.
11:58 PM Tom_L: the features are in different places in the program
11:59 PM Tom_L: that's actually a current ver as they teach it for the aircraft industry here
11:59 PM Tom_L: full package is around $75k
11:59 PM LeelooMinai: Right, well, if someone build planes, they can afford it.
