01:16 AM Crom: ugh... I need a 80mmx120mmx19mm piece of AL with 2 5mm threaded holes 53mm on center apart at one 80mm wide end and 2 5mm cleaance holes at the other end with windows so I can use it as a riser block
01:25 AM Crom: hmmm I could get it out of my other block of 40mm AL end cap
01:30 AM IchGucksLive: morning from germany
01:31 AM IchGucksLive: Crom: make a drawing DXF/DWFG
01:31 AM IchGucksLive: DWG
01:31 AM IchGucksLive: so the world can see cour idee
01:32 AM Crom: That'll have to be monday... unless I can find a dxf output here..
01:33 AM IchGucksLive: use Qcad
01:34 AM Crom: I think I have that on the IBM T60
01:56 AM IchGucksLive: Till later
02:12 AM TurBoss: hello
02:18 AM Deejay: moin
02:27 AM Crom: Moin Deejay
02:28 AM Crom: where's a good paste spot for dxf files?
02:28 AM TurBoss: https://www.sendspace.com/ ?¿
02:29 AM TurBoss: grabcad also
02:29 AM archivist: a screen image of it to save people needing a program
02:29 AM Crom: where's a good paste spot for dxf files?
02:30 AM Crom: got it..
02:32 AM Crom: https://www.sendspace.com/file/1sc10f
02:32 AM Crom: Riser Block.dxf
02:35 AM Crom: I need a riser block, 120mm tall 80mm wide, 19mm thick, with 6 holes: 2 tapped 5mm x 0.8 pitch 10-15mm deep on 53mm centers, other end is 2 5mm clearance holes and a window to put in a allen cap screw and enough extra space to swing the allen wrench 30+ degrees
02:35 AM Crom: clearance holes are also on 53mm centers
02:40 AM Crom: who could do this for me at a reasonable price?
02:54 AM XXCoder: sendspace is ok
02:55 AM Crom: XXCoder: soon as I can, I be able to send you my old spindle mount... I have to use it a couple more times
02:56 AM XXCoder: what foir?
02:56 AM Crom: 52mm spindle size
02:56 AM XXCoder: oh my machine has it now
02:56 AM Crom: You have a 48mm right?
02:56 AM Crom: never mind then hehe
02:56 AM XXCoder: I managed to make deal with seller to send just z block so i can use either 52mm or 43mm
02:57 AM Crom: nice
02:58 AM XXCoder: yeah
02:58 AM Crom: I wish I had the money for these...
02:58 AM XXCoder: well worth it. just wish I figured that 52mm had more choices than 43 back then
02:58 AM Crom: http://www.ebay.com/itm/IKO-Japanese-Linear-Rail-with-Two-Bearings-/112406167582
03:00 AM Crom: with 6 of those I could make a beefy machine
03:01 AM XXCoder: yep
03:02 AM XXCoder: I saw HUGE ones of those when I saw has 5 axis big machine special (those are rare) man those rails and screws is big
03:02 AM XXCoder: in least 2 inch diameter
03:02 AM XXCoder: though other machine has 3 inch ballscrew. insane.
03:03 AM Crom: dynamic load rating 5620 C N static is 9060
03:05 AM Crom: 1263lbf 2036 pound force static...
03:06 AM Crom: I'd be bending things if I got within a mile of those ratings
03:07 AM Crom: welp nite all..
03:07 AM XXCoder: later
03:17 AM Crom: dang it can't find my phone
03:32 AM XXCoder: hey the Wolf_
05:09 AM IchGucksLive: hi
05:10 AM XXCoder: yo
05:11 AM TurBoss: \o
05:11 AM IchGucksLive: crom seams to go on a hard mashine
05:11 AM XXCoder: TurBoss: how goes machining
05:11 AM TurBoss: didn't try anithing
05:11 AM TurBoss: I have to make some parts (not require finishing)
05:12 AM TurBoss: for the probe
05:12 AM IchGucksLive: i got the first wood mill of the new serie runuing yeaterday
05:12 AM IchGucksLive: but got some table trouble ive never expexted
05:13 AM TurBoss: I'm also trying to do a MPG with recicled parts but the encoder I have moves 2 steps sometimes
05:13 AM TurBoss: so not valid
05:13 AM IchGucksLive: it goes straight 0,05mm down to almost 2/3 of X then it falls 0,5mm on 250mm
05:13 AM IchGucksLive: i did 4 years ago a real cheep one on PCF8575 base i2C
05:14 AM IchGucksLive: but now i use the XHC
05:14 AM IchGucksLive: its easy to config and has all needed stuff
05:14 AM TurBoss: :)
05:21 AM IchGucksLive: TurBoss: http://heimwerkermarkt-tretter.de/pcb_milling.jpg
05:22 AM IchGucksLive: i dont kow it is worth to upload the old Video on this
05:24 AM IchGucksLive: With the Arduinos it is mutch easyer and also cheeper to get one going
05:24 AM IchGucksLive: and if you do not need LCD go for a Xboy controler that has 12 Buttons
05:25 AM IchGucksLive: 5USD and your mashine is in Full mpg controle
05:26 AM TurBoss: oh coool
05:26 AM TurBoss: I like the jog wheel, will buy one
05:26 AM TurBoss: only 18€
05:30 AM IchGucksLive: i found a image of the runnig let me upload it
05:30 AM TurBoss: cool
05:33 AM IchGucksLive: TurBoss: http://heimwerkermarkt-tretter.de/emc_p_v1_vv.jpg
05:33 AM TurBoss: ohhhhhhhhhh
05:33 AM TurBoss: very nice
05:33 AM IchGucksLive: its about 50 box
05:33 AM XXCoder: nice
05:34 AM IchGucksLive: i hacked the XHC-hb04 to get all the best out of it
05:34 AM TurBoss: I have som joy pads that go to the game port
05:34 AM IchGucksLive: as i need also axos movement on jbuttons
05:34 AM TurBoss: *som
05:34 AM TurBoss: ee
05:36 AM IchGucksLive: so now the First 3 STEP presses acting on Wheel 0,1.0,5 1 THEN it changes 4,5,6 press go to 250,1000,2500mm Macro-6/7 plus minus moving
05:36 AM IchGucksLive: so i got also the iconss working to show what we are on
05:36 AM IchGucksLive: donme by updown counter with compare
05:37 AM IchGucksLive: and the Wirerless leak on reset is also solved on Multiklick
05:37 AM IchGucksLive: to MODE
05:37 AM IchGucksLive: it resets the control to the xhc
05:37 AM IchGucksLive: defaulte
05:38 AM TurBoss: I'll go wired
05:38 AM IchGucksLive: so all syncronised
05:38 AM IchGucksLive: best to do
05:38 AM XXCoder: theres some pendants that have delayed response on jogging
05:38 AM IchGucksLive: it is a nice projekt
05:38 AM XXCoder: I hate thopse
05:38 AM XXCoder: office mill at work has that
05:38 AM TurBoss: delay?
05:39 AM TurBoss: that == delay?
05:39 AM IchGucksLive: he means count all jogs nomeatter what
05:39 AM IchGucksLive: so if you spinn on 1mm jog it will move lots of
05:40 AM TurBoss: oh
05:40 AM IchGucksLive: the HAAS do that also
05:40 AM XXCoder: indeed. machines at work usually do accurate count but also rapid repsose
05:40 AM XXCoder: yeah office mill is haas
05:40 AM XXCoder: tiny machine compared to other work machines\
05:40 AM IchGucksLive: cheep and usefull
05:40 AM IchGucksLive: ok im off
05:41 AM XXCoder: later
05:41 AM IchGucksLive: till later
05:41 AM TurBoss: :)
05:41 AM TurBoss: bye
05:41 AM XXCoder: om broke itself at work
05:41 AM TurBoss: om?
05:41 AM XXCoder: it apparently uses induction for Z limit switch
05:41 AM XXCoder: and chips could go inside back column and trigger sensor
05:41 AM XXCoder: so it went to wrong Z0, and tool corosel crashed into spindle
05:41 AM XXCoder: office mill, tur
05:41 AM TurBoss: :(
05:42 AM XXCoder: not my machine so no loss for me
05:42 AM TurBoss: xD
05:43 AM TurBoss: I went from 16 to 8 microsteps
05:43 AM TurBoss: because of steps begin loss
05:43 AM XXCoder: 16 is little large microstep
05:44 AM TurBoss: worked fine ...
05:44 AM XXCoder: if you want "16" then get 0.9 steppers
05:44 AM TurBoss: ah yes
05:44 AM XXCoder: then use 8 microstep
05:44 AM TurBoss: was 10% or torque
05:45 AM archivist: micro steps are not exact parts of a whole step anyway
05:45 AM XXCoder: indeed
05:45 AM XXCoder: sometimes it dont even move then next one it moves 2 microsteps
05:45 AM XXCoder: that dont happen at say 4 I suppose?
05:45 AM XXCoder: while it still varies a little
05:45 AM archivist: somewhat random amounts depending on magnetics in the motor and friction of the machine
05:48 AM TurBoss: XXCoder : did you finsh the ship?¿
05:48 AM XXCoder: the avocodo boat?
05:48 AM TurBoss: the one from that game
05:48 AM XXCoder: cant remember what you mean (sometimes my memory suck)
05:48 AM XXCoder: ahh
05:48 AM XXCoder: not yet, too lazy to print anything
05:48 AM TurBoss: ahhahahaha
05:48 AM TurBoss: :D
05:49 AM TurBoss: at least you fixed the mchine?
05:49 AM XXCoder: tomorrow maybe, though its more likely I will print induction sensor holder then re-upgrade my machine to it. switch sucks!
05:52 AM XXCoder: new clickspring!
05:53 AM * TurBoss backs to coding...
05:54 AM TurBoss: uff too lazy
05:54 AM TurBoss: ...
05:54 AM archivist: get on with it!
05:54 AM archivist: :)
05:55 AM archivist: I know the feeling well, walk away do something else, and the answer hits you
05:55 AM TurBoss: :D
05:56 AM archivist: now get me nice responsive buttons for a website :)
05:57 AM archivist: I have some but multi level really screws you on a touch device
05:57 AM TurBoss: I use the ionic framework
05:58 AM TurBoss: web Ios android
05:58 AM archivist: no effin js frameworks
05:58 AM XXCoder: damn
05:59 AM XXCoder: clickspring guy is crazy sometimes
05:59 AM XXCoder: he brings up ponental methof of making accurate gear in various teeth numbers
05:59 AM archivist: using css and real html so any browser works however old(almost)
05:59 AM XXCoder: he then does it.
05:59 AM XXCoder: using old style tools even
05:59 AM TurBoss: my focus is on apps
06:00 AM TurBoss: maybe some browser in kiosk mode
06:00 AM XXCoder: https://www.youtube.com/watch?v=BIUAdINXZmQ
06:01 AM archivist: the site I am doing is focused on older people with older browsers
06:01 AM TurBoss: cool
06:01 AM XXCoder: older and more exploitable browsers
06:01 AM archivist: the customers with the spare cash
06:01 AM TurBoss: wowowoow 3 listemers
06:02 AM TurBoss: on my radio
06:19 AM XXCoder: os/2 warp is back
06:19 AM XXCoder: arcaOS 5.0 name now
06:19 AM TurBoss: oh
06:20 AM XXCoder: $129 for personal and $239 for commerical
06:20 AM TurBoss: i need somthing that runs on my 386 scb
06:20 AM TurBoss: booo
06:20 AM XXCoder: I guess people with old telcom system can finally update those
06:20 AM TurBoss: *sbc
07:08 AM jthornton: morning
07:08 AM XXCoder: hey jt'
07:08 AM TurBoss: o/
07:09 AM * Tom_L checks his sundial
07:09 AM * XXCoder checks his hourly candles
07:10 AM XXCoder: wow its down to halfway between 4 and 5 am mark
07:10 AM * XXCoder double checks with water clock. yep its around same
07:10 AM jthornton: I've been up since 5am trying to get light levels from the ardweenie but the counterfit usb chip gave me fits
07:11 AM XXCoder: sucks
07:11 AM jthornton: Gene_home: the devel channel is not the best place to ask for slic3r questions...
07:12 AM jthornton: Tom_L: did you get the update to the logger?
07:12 AM Tom_L: a new one?
07:12 AM Tom_L: i installed it the other day
07:12 AM jthornton: from the other day
07:14 AM Tom_L: 5/19
07:15 AM jthornton: no KGB since then
07:15 AM jthornton: I see it does not log the -linuxcnc-github/#linuxcnc-devel- comments
07:17 AM TurBoss: Til #linuxcnc-devel exist :D
07:17 AM archivist: what time in japanese :) Japanese traditional timekeeping practices required the use of unequal temporal hours: six daytime units from local sunrise to local sunset, and six night time units from sunset to sunrise.
07:18 AM archivist: that sorts the candles from the sundials
07:29 AM jthornton: https://www.thingiverse.com/thing:1959019
07:37 AM archivist: isnt a project box off fleabay cheaper
07:38 AM Deejay: why care about the price if you can make it with your own hands/machines ;)
09:29 AM phiplii: jthornton: I like that - what is the board in the very bottom?
09:29 AM phiplii: ftdi?
09:29 AM phiplii: radio?
09:30 AM phiplii: ah - can see an antenna socket
09:30 AM phiplii: (the green box with a nano in it)
11:54 AM * LeelooMinai wonders if JT-Shop will eventually eat those chickens
11:56 AM TurBoss: at least the eggs
11:56 AM TurBoss: :D
12:21 PM IchGucksLive: hi
12:22 PM LeelooMinai: Hm, maybe someone will fine it useful. Found whole g-code CNC/milling tutorial/course series on youtube by some guy: https://www.youtube.com/playlist?list=PL35sMcDwCf0iXK_K4H_m_V-8HbmI8MS55
12:22 PM LeelooMinai: find*
12:23 PM LeelooMinai: It's pretty basic, but seems comprehensive at least.
12:26 PM IchGucksLive: LeelooMinai: did you see mine
12:27 PM LeelooMinai: IchGucksLive: I remember I watched one video - was that where I commented that's a bit weird doing it all by hand? :)
12:28 PM Loetmichel_: anyone an idea how to get an BMW M43B18 including manual gearbox in a pallet into my Opel Omega? is it possible to lift that with two guys? or better get some 2by4 and a winch?
12:29 PM IchGucksLive: LeelooMinai: you remember it so it is a good one
12:34 PM Loetmichel_: s/in/on
12:35 PM LeelooMinai: Weird how I remember things like that, but yesterday I was looking for something in my room for half an hour and the last thing remembered about it was me thinking "this is important, I must to put it in a place that it will be easy to find":/
12:35 PM LeelooMinai: Still have not found it btw
12:38 PM archivist: Loetmichel_, tool rental companies have engine lifts
12:39 PM Loetmichel_: archivist: and that helps me how to get the motor in the trunk?
12:39 PM archivist: also known as engine crane
12:39 PM Loetmichel_: i know it as "motor hoist" ;)
12:40 PM LeelooMinai: Imo put it on a bridge, put the car undeneath and drop it:)
12:40 PM archivist: as useful for chucking engines in other orifices
12:40 PM malcom2073: I've stuck an engine in the boot with a hoist before
12:40 PM malcom2073: Also done it with two guys on another occasion, might need pretty strong guys if it's heavy :)
12:41 PM archivist: smaller engines, rope around shoulders
12:42 PM malcom2073: buddy of mine tossed a toyta tercel engine in himself
12:42 PM malcom2073: was only like 2-300lbs
12:42 PM Jymmm: Must had a hellva indigestion, and then pooping a motor... YEOW!
12:42 PM Loetmichel_: problem is that the station wagon has a nice little "upwards swigning door"... so a normal crane will not help
12:43 PM archivist: I did a Vauxhall viva on my own, and a land rover gearbox
12:43 PM Loetmichel_: i dont want to mount it in the car, i want to get it home from the (private) seller!
12:43 PM archivist: we know
12:43 PM malcom2073: Loetmichel_: That's what I'm talking about, putting it in the trunk
12:43 PM LeelooMinai: Loetmichel_: Considering you are 125kg, you could borrow a te totter from the nearby park, put the engine on one end, then jump on the other and... profit:)
12:43 PM sync: yeah malcom2073, they are not heavy
12:43 PM archivist: muscles and grunt or hire a van
12:44 PM Loetmichel_: LeelooMinai: could work ;)
12:44 PM IchGucksLive: LeelooMinai: i worked last wek on the solar system with a special screw driver and it is only to be in the tiny space there
12:44 PM Loetmichel_: engine alone is 116kg, pallet should be around 15kg, no idea what the gearbox is though
12:45 PM IchGucksLive: LeelooMinai: and after 5min it han not bee seen since then
12:45 PM malcom2073: Find a friend, that's doable
12:45 PM Loetmichel_: i could do it by hand if i had a second person like me ;)
12:45 PM archivist: use a van if on a pallet
12:45 PM malcom2073: Or strap it tight against the underside of a engine hoist, I've done that to stick things in a station wagon with low clearance
12:45 PM Loetmichel_: my coworkers are sadly not that "hoist-capable" ;)
12:46 PM LeelooMinai: IchGucksLive: What do you mean "on a solar system" - are you one of those people that think they are god? :)
12:46 PM IchGucksLive: hi ruoxi if you need cnc help just ask we are hanging around over the world
12:49 PM IchGucksLive: LeelooMinai: im full on solar head here
12:49 PM IchGucksLive: home build
12:49 PM IchGucksLive: 800 euros
12:50 PM LeelooMinai: You mean one of those projecting things for planetariums?
12:50 PM IchGucksLive: no solarenergie
12:50 PM IchGucksLive: hot water for the shower
12:50 PM IchGucksLive: let me go outside and make photo of the garden
12:51 PM LeelooMinai: lol, ok - I was confused for a bit:)
12:51 PM Loetmichel_: ... problem solved. I just bought an engine hoist. -> http://www.ebay.de/itm/282402279185
12:51 PM Loetmichel_: should be sufficient
12:51 PM LeelooMinai: Hmm that's cheap.
12:55 PM IchGucksLive: LeelooMinai: near live view of outside the window http://heimwerkermarkt-tretter.de/solar_2017.jpg
12:55 PM IchGucksLive: see how high the tomatos are inside the grewenhouse
12:56 PM IchGucksLive: sun is near down so solar system is in Fix position it Rotas over the Day
12:56 PM LeelooMinai: Hmm
12:56 PM IchGucksLive: salat is in full use
12:57 PM IchGucksLive: PokChoi is also good growing
12:57 PM LeelooMinai: I wanted to build/buy a greenhouse for my mom, but she did not want one:(
12:58 PM IchGucksLive: bad for here
12:58 PM IchGucksLive: good for you still junkfood
12:59 PM IchGucksLive: LeelooMinai: ive been also for years a good planet viewer Astronomic observer
12:59 PM IchGucksLive: as you thought
01:00 PM Loetmichel_: LeelooMinai: chinesium
01:00 PM IchGucksLive: but now on my age i like to go to bed early
01:00 PM Loetmichel_: but i think it will lift the motor even on the outermost position
01:00 PM IchGucksLive: i own a 8" mead and got a 14" in range to view
01:01 PM IchGucksLive: indeed i did set up a 6" maksutov yesrerday evening on the firereengine BBQ
01:01 PM IchGucksLive: but the beer has been more interesting to the guests
01:01 PM IchGucksLive: beer
01:01 PM the_wench: I am not your waitress!
01:08 PM IchGucksLive: Q does someone know the name of the PLUG on the tb6560 boards for the switches
01:10 PM IchGucksLive: http://www.soonwell.com/ebay_file/new_pic/3Axis_TB6560-1.jpg
01:11 PM LeelooMinai: Hmm, I searched, searched, and cannot find anything about ERnn nut style differences. I only found something about the bearing kind type, but no idea what is the difference about ERxx-A -B and the "castle" one, M.
01:11 PM IchGucksLive: the white one between the opocopplers left down
01:11 PM Loetmichel_: IchGucksLive: these? http://de.rs-online.com/web/p/leiterplatten-printklemmen/8024978/
01:12 PM IchGucksLive: no the print 5 pin
01:12 PM IchGucksLive: i think they nesure 2mm not 2.54
01:13 PM LeelooMinai: IchGucksLive: You are wiring stuff, right? Have you that neat wire-terminating/clamping systems I shown few days ago from ali?
01:14 PM IchGucksLive: LeelooMinai: the mach3 5axis
01:15 PM LeelooMinai: IchGucksLive: I have been using this thing past days, and it's awsome: https://goo.gl/MVdEQq
01:16 PM IchGucksLive: i use them also
01:16 PM IchGucksLive: but not for plags
01:16 PM IchGucksLive: its a 5 pin terminal
01:16 PM IchGucksLive: CN standard
01:16 PM LeelooMinai: Well, those Phoenix plugs have screws clamps inside too.
01:16 PM IchGucksLive: cand find them in europ
01:17 PM LeelooMinai: So you have to terminate wires somhow, no?
01:17 PM IchGucksLive: the switches on the tb6560 3 axis are only on that therminal located
01:18 PM IchGucksLive: the last order of 6 boards dident came with the cable
01:20 PM IchGucksLive: oh i see our friend in australia did his side on POV http://www.hobbycncaustralia.com/Instructions/iI19wirelimit.htm
01:22 PM LeelooMinai: lol, that's a lot of work to just show some wiring:)
01:22 PM IchGucksLive: hobby folks love that
01:22 PM IchGucksLive: ive seen exact cable colors and wirering
01:23 PM LeelooMinai: A bit overkill, but ok - I guess someone new will find this useful.
01:26 PM Loetmichel_: LeelooMinai: if you have the right plugins for the renderer/3deditor its actually not that much more work than making schematics
01:26 PM Loetmichel_: Target3001 does that for PCBs really nicely
01:26 PM Loetmichel_: for example
01:26 PM IchGucksLive: agrees target doe output cool pov views
01:27 PM IchGucksLive: sirens sounding i need to move to firerhouse maybe cleaning the BBQ yesterday
02:08 PM LeelooMinai: That was scary...
02:09 PM Deejay: hm?
02:09 PM LeelooMinai: I saw on some youtube video once that you can take this black part off, and it has a slot in there that you can use to break off the blade parts: http://i.imgur.com/BLnaW63.png
02:10 PM LeelooMinai: So I thought, "o, didn't know that"... and I just tried it - the damn plastic thing broke in half and I was lucky not to have my finger cut in half...
02:10 PM Deejay: outch
02:10 PM LeelooMinai: I guess whoever thought it's a good idea, was wrong.
02:27 PM CaptHindsight: https://www.kickstarter.com/projects/1474681136/evezor-open-source-robotic-arm-manufacturing-platf
02:29 PM LeelooMinai: Right, that will work great - not:p
02:31 PM LeelooMinai: Nice story though - "when I think what I can make, I don't think what I can make - I think what you can make"...
02:32 PM malcom2073: Wow, any more dripping marketspeak and you'd need a mop
02:33 PM Crom: I need a riser block https://www.sendspace.com/file/1sc10f
02:33 PM LeelooMinai: Sounds like a politician speach almost:)
02:33 PM malcom2073: That being said, the laser coaster idea is actually pretty nifty with the ability to load/unload
02:33 PM LeelooMinai: speech*
02:33 PM Crom: 120mm tall, 80mm wide 19+mm thick
02:33 PM malcom2073: Crom: Don't have a mill to make one?
02:34 PM LeelooMinai: Crom: You could also show a cpiture or something - who has time to download DXF:)
02:34 PM Crom: not at the moment... spindle died and Z is all taken apart.
02:35 PM LeelooMinai: Crom: I had same problem few days ago - used a table saw + no-ferous metal cutting blade
02:35 PM LeelooMinai: non-ferrous even
02:36 PM LeelooMinai: and when I was building the CNC I also used a tabler router to "mill" - a bit problematic, but can work if you keep things safe.
02:36 PM Crom: hmmm that's an idea... I'd have to save up for a non ferrous blade..
02:37 PM LeelooMinai: Crom: I just MacGyvvered it quickly: https://www.flickr.com/photos/100017731@N03/33923475284/in/dateposted-public/
02:37 PM LeelooMinai: And used the blade vertical positioning as a feed of sorts.
02:38 PM LeelooMinai: I also used a mitre saw to cut aluminum with that blade - works too, if you can clamp things reliably.
02:39 PM Crom: be fun keeping things parallel and perpendicular
02:40 PM LeelooMinai: Well, if your saws are set right, it will be - at least was in my case. Not mill-exact, but was sufficient.
02:40 PM LeelooMinai: I also used using a small bandsaw, but that was fail:)
02:40 PM LeelooMinai: tried using*
02:40 PM roycroft: it would be hard to hold closer than 0.010" with a chop saw or table saw
02:41 PM roycroft: but you could file it square after the cut
02:41 PM LeelooMinai: Well, mine is some $400 Dewalt - it's decent I guess.
02:42 PM LeelooMinai: But I also buolt myself one nice sliding sledge or what it is called for it - it has been super useful.
02:42 PM Crom: My Chopssaw is a Rigid Compound mitre saw with 12" blade. Table saw is a 1960's or 70's Craftsman table saw
02:43 PM Crom: 10"
02:43 PM LeelooMinai: Crom: Do you have a aledge for the table saw?
02:44 PM Crom: made one...
02:44 PM LeelooMinai: I found it great for cutting aluminum pieces.
02:44 PM LeelooMinai: Right, I made one two - it's pretty neat - has some improvements over "normal" ones.
02:44 PM LeelooMinai: too*
02:49 PM LeelooMinai: Took a photo: https://www.flickr.com/photos/100017731@N03/33961703474/in/dateposted-public/
02:49 PM LeelooMinai: Now I could slowly maybe mill the sides from aluminum:)
02:51 PM Crom: http://picpaste.com/Riser_Block-5Qng3RBA.png
02:51 PM LeelooMinai: Since they are the most crucial part. Plus using something nice for the rails underneath that go into tabltop slots - I used I think HDPE ones.
02:51 PM Deejay: aaaaaaww https://www.flickr.com/photos/100017731@N03/22415871378/in/dateposted-public/
02:52 PM LeelooMinai: That's Pixi:)
02:52 PM Crom: I'm using maple
02:53 PM Crom: I need to redo my head and foot boards, your 90 to 45 degree are nice
02:53 PM Crom: mine is 90 onlt right now
02:54 PM LeelooMinai: Right, it's hard at last - the sides of mine are from maple. But, woods have tendency to change with moisture and temperature, so, if the "humid" times come, you can no longer have straight rails.
02:55 PM Crom: yep.. HDPE sounds nice.. I do have an sears miter gauge that's dead.. I can steal the bar from
02:55 PM Crom: sears doesn't have 1/2 slots
02:55 PM Crom: 1/2"
02:57 PM LeelooMinai: I think I even tried some oak + waxing it, to be slippery, but one day the thing just seized due to moisture probably, so, I would recommend aluminum or hdpe - worth the extra cost.
02:58 PM LeelooMinai: Hmm, I will try to make my axis straight again today.
02:59 PM newbe: hi all, i'm using linuxcnc with a parallel port breakout board and A4988 drivers. I already managed to get the x-axis work. but I have a question: Does the polarity of the 1A1B and 2A2B coils matter? I can't find any difference (works both ways the same)
03:00 PM LeelooMinai: For a stepper motor?
03:00 PM newbe: yes, a 4 wire stepper with 48 steps/round
03:00 PM LeelooMinai: Not 100% sure, but I think if it works, you are fine.
03:02 PM newbe: Ok, thanks. Could it be, that it only makes a difference when using micro stepping? currently I have "driver microstepping" = 1.0 configured
03:03 PM cpresser: newbe: the polarity will change rotation direction
03:04 PM LeelooMinai: Many people seem to wire steppers by "trial and error", so my guess is that you cannot really wire it in some catastrophic way.
03:05 PM LeelooMinai: Sans, connecting to mains:)
03:06 PM newbe: got to check that...
03:10 PM LeelooMinai: You can also find a pair easily by shorting cables randomly and turning the axle by hand - it will be harder if you have a pair shorted.
03:10 PM Loetmichel_: ha, i think i have a run. a co-worker from a job 20 years ago and 300km away just called me... he as a problem with an Alfa romeo convertible that i could help him with over the phone.. i mentoined my predicament with the BMW 318i convertible that threw a rod... His answer: "what? E36 engine? no problem, i have a friend here that rebuilds them. i'll ask him tomorrow if he as a cheap one thats
03:10 PM Loetmichel_: guraneed to run... and i have to go south to deliver a car next week anyway... so i can deliver that engine to you for free if you want..."
03:11 PM LeelooMinai: "Also, I have just won a lottery, and I have to give 1% to a random person to get a tax break - you want that?
03:12 PM Deejay: no, thanks. give to another person that needs it more!
03:12 PM Deejay: thats what Loetmichel_ would answer
03:12 PM Deejay: ;)
03:12 PM Loetmichel_: probably ;)
03:17 PM Loetmichel_: anyway, its alwaays good to not burn any bridges behind oneself... you'll never know when old aquaintances come in handy ;)
03:21 PM LeelooMinai: Yes, well, it's a double-edged sword though: you may one day find out that they are murderous psychopaths.
03:33 PM Loetmichel_: LeelooMinai: not very likely
03:35 PM phipli: JT-Shop, Our new birds have been delayed - we should have got them this week gone :(
03:35 PM phipli: Don't know when they'll get here now
03:41 PM JT-Shop: I hate when something doesn't show up on time
03:41 PM JT-Shop: just about to finish the automagic chicken door mark II
03:43 PM LeelooMinai: "It's like Mark I, but has sharpened edge, so can act as a gillotine"
03:45 PM Loetmichel_: ... and got an beefed um motor so ith shuts in less than a millisecond ;)
03:45 PM Loetmichel_: s/shuts/closes
03:51 PM phiplii: send us a picture when you're done - I'd be interested to see
03:51 PM phiplii: what method did you use?
03:52 PM JT-Shop: I'll upload some photos in the morning during free time
03:53 PM JT-Shop: I used an Arduino Nano clone and a photo sensitive resistor to tell night and day
03:53 PM JT-Shop: the gear motor I showed you the other day and a couple of DPST 5v relays, one to set direction and one to turn the motor on and off
03:56 PM JT-Shop: and a SPDT switch for manual up/down and center for auto
03:58 PM phiplii: anything for chicken detection?
03:58 PM phiplii: or is it not directly coupled to the door for that reason
04:02 PM JT-Shop: the door moves very slowly and is light enough to not hurt a chicken
04:03 PM JT-Shop: I also used a couple of 2020 rails for the door to slide in this time as the wood rails were a bit sticky from time to time going up
04:11 PM phiplii: I was thinking this sort of thing : https://www.amazon.co.uk/Pairs-Bearing-Drawer-runner-GTV/dp/B01H2T0SIK/
04:12 PM JT-Shop: sorry but I can't do much surfing right now, I'm down to less than 1.8Gb left for the month... I'm on sat
04:13 PM phiplii: ah right
04:13 PM phiplii: np
04:13 PM phiplii: just ball bearing drawer sliders
04:13 PM phiplii: usual sort of thing
04:13 PM JT-Shop: but drawer slides should work fine
04:25 PM Deejay: gn8
04:25 PM JT-Shop: all modes are working well, I'm happy
04:25 PM JT-Shop: goodnight Deejay '
04:27 PM JT-Shop: phipli: I like the 2020 for slides as it is plenty loose for chicken crap
04:29 PM phiplii: are you just running a board in the slot?
04:31 PM JT-Shop: yea it's just a 1/8" aluminum plate running in the slots of the 2020
04:40 PM LeelooMinai: Is it sane to try making x-axis horizontal to the table with having the z-stage on it? I am trying to do it with rail screws untighten and moving the z-stage around, but seems a bit voodoish.
04:43 PM LeelooMinai: I put a surface plate on the table and have an arm + indicator attached to z bed and the indicator rides over the plate with x movements.
04:49 PM Crom: all that will do is tram te z tothe table.. you need to move one end of x up or down while indicating
04:49 PM sync: LeelooMinai: you cannot assume your surface plate to be parallel to the bottom tho
04:51 PM LeelooMinai: Right, I am assuming that XY plane is a plane at this point - just want to set up X.
04:51 PM Crom: do you have any long parallels?
04:52 PM LeelooMinai: No
04:52 PM LeelooMinai: I once look at those, but they were very expensive.
04:53 PM LeelooMinai: sync: You meant that the bottom side of a plate is not guaranteed to be parallel to the top
04:53 PM LeelooMinai: ?
04:53 PM sync: yes
04:53 PM Crom: indicating to the surface of the table you should have mostly same distance when X min to X max
04:55 PM LeelooMinai: Right, well, that's what I do, but, the z -stage has a weight, so when I move it around to tighten screw, etc., it also interacts with the rails, etc.
04:55 PM Loetmichel_: JT-Shop: linear rails for a chicken door? if thats not overenigeered i dont know what is ;
04:55 PM Loetmichel_: )
04:56 PM LeelooMinai: Hmm, I think I need to devise a better strategy.
04:57 PM LeelooMinai: Wish I could just slide the whole z-part of the rails, but it's not happening with a fixed gantry.
04:58 PM LeelooMinai: Well, I guess fixed or not, with a gantry tht is wide.
04:59 PM JT-Shop: did you put linear rails on your chicken door?
05:05 PM Crom: Been thinking about how to cnc my sewing machine...
05:07 PM XXCoder: that'd be essentally cnc router
05:07 PM XXCoder: just different "spindle"
05:07 PM Crom: thinking of only using 2 linear shafts
05:08 PM Crom: and using belt drive
05:09 PM Crom: take out my feed dogs (the teeth under the pressor foot. Put in my embroidery needle plate and pressor foot.
05:10 PM Crom: make a fair sized embroidery hops cept make it rectangle and in various sizes so I can clamp in different sizes of leather or fabric
05:10 PM Crom: s/hops/hoops/
05:11 PM Crom: I can change the machine to leave needle up at stop. and I can feed it a timed pulse to make a stitch
05:13 PM XXCoder: if you seperate top and bottom and use encoded motors to keep them in sync you'd have unlimited surface area.
05:14 PM Crom: I really want it not for sewing, but for making lines (rows of holes) on leather to cut out
05:14 PM Crom: I could use it for really slow embroidery
05:15 PM Crom: poking holes for stitches would be nice too..
05:18 PM LeelooMinai: Hmm, I wonder - if it's just my desing, or detaching z-stage from z-rails does always involve a lot of work and disassembling most of the z-stage?
05:18 PM LeelooMinai: from x-rails*
05:20 PM LeelooMinai: Looking at random images on google
05:21 PM LeelooMinai: You must be kidding me... He crept even into my CNC interests:( http://www.industrialmachinery.com/store/images/9977.jpg
05:22 PM Crom: hmmm possibilities http://www.ebay.com/itm/BELT-DRIVE-ACTUATOR-FAST-MOTION-LINEAR-MOTION-UNIT-75mm-Lead-520mm-Stroke-/201579472172
05:22 PM XXCoder: trump isnt good name for machine.. thump - crash!!!
05:23 PM Crom: thinking 20mm linear shaft on the back under the table for X. Y would ride on the X shaft and be a belt driven linear actuator y stepper shaft parallel to the X shaft.
05:24 PM LeelooMinai: Bugger that - taking my z-stage apart.
05:37 PM LeelooMinai: Probably should have a small cordless screwdriver that can hinge in the middle, so you can use it at different angles.
05:39 PM LeelooMinai: Something like this, but cheaper: https://www.amazon.ca/Bosch-Bare-Tool-PS10BN-i-Driver-Exact-Fit/dp/B009K1H3VE/ref=sr_1_1?ie=UTF8&qid=1495404540&sr=8-1&keywords=bosch+i-driver
06:09 PM Crom: I was looking at that ball worm drive... it's really easy to get around the patents... make the inner rail, put it together with the outter and weld them together... 1 patent is screws, the other is pinned
06:10 PM malcom2073: The problem isn't getting around the patents, it's affording to defend yourself in court until you win
06:14 PM sync: or you just make it and don't care
06:14 PM sync: just don't research if it is patented
06:17 PM malcom2073: If you're not making money off it, worse they'll do is a cease and desist, usually
06:37 PM LeelooMinai: Sad... One day you jog the z-axis, something crashes, and two days later: https://www.flickr.com/photos/100017731@N03/34676386501/in/dateposted-public/
06:38 PM XXCoder: aw
06:38 PM LeelooMinai: Who whould have thought that there's so many screws in a CNC:)
06:38 PM XXCoder: lol yeah
06:42 PM jdh: you disassembled a stepper motor?
06:43 PM LeelooMinai: Yes, that too - was curious if something got messed up inside besides the mount "ear" that cracked.
06:44 PM LeelooMinai: But did not seem so.
06:44 PM LeelooMinai: Still, it's not what it was before. But it works up to 45 mm/s or so, so for now I will leave it.
06:46 PM jdh: there are many places that say reassembled steppers will never work correctly. no clue if they are really accurate though.
06:46 PM sync: depending on the magnet material you might have lowered the flux
06:46 PM LeelooMinai: Well, i did not really care that much - but seems that whole operation did not make it worse.
06:47 PM jdh: yeah, that has been the case when I did the same.
06:49 PM LeelooMinai: I also had to disassemble on of those indicator arm magnetics block yesterday (needed to re-tap it for M5) and it was not what I expected inside - seems that there's a magnet there with a slot, but it only is rotated by 90 degrees - I thought it will be lowered to the bottom or something for some reason.
06:50 PM LeelooMinai: But it's a big cylinder of a magnet.
06:50 PM XXCoder: interesting
06:50 PM XXCoder: induction I guess it detects motion of metal near it, since alum arent magnetic
06:51 PM XXCoder: and my printer uses induction on alum.
06:52 PM LeelooMinai: Not sure exactly what is going on there - probably the magnetic field is interacting with the metal enclosure and somehow at 90 deg rotation it's gone from the base.
06:53 PM LeelooMinai: Hmm: https://upload.wikimedia.org/wikipedia/commons/thumb/0/0a/Wiki_MagneticBase_ALL.svg/200px-Wiki_MagneticBase_ALL.svg.png
06:53 PM LeelooMinai: So that base is not even one piece.
06:54 PM LeelooMinai: So at 90 deg, each metal plate "eats" the field...
06:57 PM LeelooMinai: Er, seems the oposite - in on position they bercome part of the poles, and in off-position poles point to the non-ferrous part.
07:04 PM Crom: hmm the round magnet is 2 pieces
07:04 PM Crom: housing is 3 pieces on mine as well...
07:08 PM Crom: the split line on my magnet is vertical in on.. and horzontal in off
07:10 PM Crom: hmm one side is north and the other side is south in on..
07:12 PM sync: interestingly killing the flux does not happen that often with modern rare earth magnets that have high coercivity
07:37 PM LeelooMinai: Watched robot wars again- I wonder how people get to that TV competition stage: some designs are pretty absurd:)
07:45 PM XXCoder: here should be sub-compeitions to weed out shitty designs
07:45 PM XXCoder: but theres not enough
07:47 PM LeelooMinai: Well, I wonder if they let some weird ones in just because it may be fun to watch them fail.
07:48 PM LeelooMinai: Like 8-legged walker that in competition of 3 barely managed to crawl into the middle of the arena throughout the whole battle:)
07:49 PM XXCoder: lol
07:49 PM XXCoder: I remember that spinny thing
07:49 PM XXCoder: it had done very well till one of attachments on dome broke off
07:49 PM XXCoder: it got imbalanced and flipped off off area
07:50 PM XXCoder: made me wonder if textured spinner would be better
07:50 PM XXCoder: nothing to break off
07:50 PM LeelooMinai: Er, which one - there's a lot of things that spins something there.
07:50 PM XXCoder: and its counterspinning something inside so overall torque is zero
07:50 PM XXCoder: no not one youre watching, its old show
07:51 PM LeelooMinai: Right, I got back to watch the older ones.
07:51 PM LeelooMinai: I am at season 4 now.
07:51 PM XXCoder: oh well its been too long for me to remember lol (maybe one of firsts?)
07:52 PM XXCoder: its pretty memorable though, it starts shaking around then flip and hits floor with dome and spins off arena
07:53 PM LeelooMinai: Hmm, I remember something flying like a freezbee at some point, forgot what it was though.
07:54 PM XXCoder: I think that was one
07:55 PM XXCoder: it had 2 attachments, and one broke off
07:55 PM XXCoder: so it was out of balance
07:57 PM LeelooMinai: I watched the new ones too - like US battlebots. At this point they are kind of scary though. Like that Carbide one. I wish nets were allowed to counteract those crazy spinning ones.
08:00 PM XXCoder: yeah
08:01 PM Crom: spinny one that was the myth busters guy jaime wasn't it?
08:02 PM sync: there are lots of spinny ones
08:02 PM sync: it is a clever design tho
08:02 PM sync: lotsa energy with low-ish weight
08:02 PM XXCoder: yeah
08:02 PM Crom: tons and tones of inertial energy
08:02 PM XXCoder: slow spinup though
08:03 PM XXCoder: Crom: dunno about mythbuster but one im talking about predates that show
08:03 PM Crom: takes time to input energy
08:03 PM Crom: probably jaime's that was pre mythbusters
08:03 PM sync: that just depends on your motor and how much current your batteries can deliver
08:04 PM Crom: he used a chain saw engine
08:05 PM XXCoder: if floor was metal I'd use pretty powerful magnet that can be turned on and off
08:05 PM XXCoder: like one of those indictor arm holder magnets
08:05 PM Crom: heh magnetic chuck upside down
08:06 PM XXCoder: if there was few of those, can even use em as movement, that'd be nearly impossible to push
08:06 PM LeelooMinai: Not sure what the floor is nowadays made from, but I like the wheels that had carbide spikes on them - I think from golf shues or something. I think that's the way to go.
08:06 PM XXCoder: Crom: basically.
08:07 PM XXCoder: it'd be slow but essentally unstoppanle
08:07 PM XXCoder: use a dome that is not fixed so it rotates if something is attacking it
08:07 PM XXCoder: so say if something is using chainsaw it would spin
08:08 PM XXCoder: making it hard to cut
08:09 PM LeelooMinai: Right, that's another thing - some people were driving those things without sense:)
08:11 PM LeelooMinai: As they tried on purpose to neutralize the only strong points they had.
08:14 PM LeelooMinai: I would not even think about entering without covering the main and clear points that one needs to have good prospects. Like good agility, ease of repair, no way to get turned upside down or on the side and be stuck, no external weak points, like rubber tires, exposed chains, etc. - I would think that people would start by listing those, and then designing something:)
08:23 PM Crom: well you need some sort of pliable tire to move quickly.. And have a weapon which uses inertia for best energy density in attack
08:24 PM LeelooMinai: Right, but I mean, you would start with covering basics, while some people have designs like they never watched an episode.
08:24 PM Crom: I always liked a spinning flywheel or flywheels for energy storage. A clutch that can withstand insane amounts of energy transfer
08:25 PM Crom: flywheels also help against flipping
08:25 PM LeelooMinai: Right, those and gas flippers seem to do well. The braziliang gus for example had it done pretty well.
08:27 PM LeelooMinai: I guess the precession effect will oppose changing the axis of rotation, but not sure how strong it is.
08:27 PM LeelooMinai: But, there are also drawbacks, like you can hit something statinary and self-destroy.
08:28 PM Crom: I don't like exposed flywheels
08:29 PM LeelooMinai: Well, you need to expose it or how are you going to attack with it? :)
08:31 PM Crom: dump clutches to change the rotary motion into linear motion, stab spears or hammer arms or pincers
08:32 PM LeelooMinai: Somehow I did not see one case where a spike-like weapon did anything.
08:32 PM LeelooMinai: Useful that is.
08:32 PM XXCoder: lol
08:33 PM LeelooMinai: Hammer-like and axes seemed to be a bit better, but not really the best.
08:34 PM LeelooMinai: Having something like a rotatin drum + flipper is a pretty safe way of not making a fool of oneself:)
08:35 PM XXCoder: I seem to recall that had one powered spike?
08:35 PM XXCoder: it draws back and rapidly extends it?
08:37 PM LeelooMinai: Right, there was at least one, but, not surprisingly, did not really do much - with this kind of weapon you need eother luck or an opponent that has exposed weak spot.
08:38 PM LeelooMinai: WHereas with some crazy spinning contruption you just go straight on and shred and that's the whole plan.
08:38 PM Crom: stab spear can be modded into a great flipper...at the end you have a accelerator. the spear is 2 layers, bottom stops and the top travels a bit further and the accelerator arm at the end pivots up since the top part is still travelling
08:39 PM LeelooMinai: I don't know - sounds to "cute" to be effective to me.
08:41 PM LeelooMinai: I don't think I have seen anyone yet doing something super-clever. It is mostly by brute force and driving skills, agility, shear drivetrain power, etc.
08:43 PM Crom: at the back end.. you could have another accelorator to slow down the bottom and give the top an extra push
08:43 PM LeelooMinai: well, sans the guy who has hidden a net in a box for a spinner, but that was deemed illegal.
08:44 PM LeelooMinai: But the spinner was dead in 1 second:)
08:44 PM Crom: wedge always did petty good..
08:45 PM LeelooMinai: Well, imo that's like a flipper, but you use momentum of the whole bot instead of an actuator.
08:48 PM Crom: hmmm what gas is good fordriving a flipper or pincher
08:49 PM LeelooMinai: I think they use liquid, er, CO2?
08:50 PM LeelooMinai: Though I thought I heared them say CO
08:50 PM LeelooMinai: But is't that poisonous? :)
08:53 PM LeelooMinai: I remember when I was doing MTB, I had a CO2 cartridge to quickly pressure tires in case of puncture, so probably that's the same idea.
08:57 PM jdh: traded in MTB for CNC?
08:58 PM LeelooMinai: Moved to Canada, then as hjobby I had electronics, then CNC I guess.
09:00 PM Crom: hmmm you can't use combustion except for engines right?
09:01 PM Crom: and torches
09:03 PM LeelooMinai: I would be surprised if you could use a flame thrower:)
09:03 PM LeelooMinai: I saw one case where they had some kind of torch and actually won with it.
09:03 PM Crom: can't use caseless ammo to fire stabbers
09:03 PM LeelooMinai: No, no projectiles for sure:)
09:04 PM Crom: it's a retained projectile...
09:04 PM Crom: atf would have a fit....
09:05 PM LeelooMinai: They allowed drones weirdly though - one got destroyed with an actual rake attached to a bot, which was pretty funny.
09:09 PM Crom: use a gas and oxidizer your fine... use a solid substance.. your ass is gras...
09:12 PM LeelooMinai: Right, they don't want it to end up as mini-wwII battle
09:20 PM Valen: oxidisers aren't allowed in robot wars
09:20 PM Valen: generally flippers are powered by CO2
09:21 PM Valen: pinchers generally suck and in an attempt not to are hydraulic powered
09:21 PM Valen: unteathered projectiles are not allowed
09:22 PM Valen: next season for robot wars (uk) entanglement devices are allowed
09:22 PM Valen: I think thats the season filming over the past few days
09:24 PM Valen: The spinners have KE's far far in exess of armour peircing .50's
09:24 PM Valen: our 13.6kg ones are in the same ballpark as a .50
09:24 PM LeelooMinai: Awsome - nice to know that I had the right idea for that:)
09:25 PM LeelooMinai: Valen: What do you mean "our"
09:25 PM Valen: Here's a 1.36 kg one I made with linuxcnc ;-> http://imgur.com/a/ccQ3N
09:25 PM Valen: I compete in robot wars in australia
09:25 PM Valen: A group of our people got together to build deathroll
09:26 PM LeelooMinai: A, great - I think I saw some Australians once, but in bottle bots? Somwhere...
09:26 PM Valen: battlebots would have been the kkeros from ages ago
09:26 PM Valen: wait battlebots is the US one
09:26 PM Valen: that was deathroll
09:26 PM Valen: got it's ass kicked in like 20 seconds by a ring spinner
09:27 PM LeelooMinai: Well, there is this guy that is having an easy mode every time, what is that bot...
09:27 PM LeelooMinai: Tombstone
09:28 PM LeelooMinai: With nets it would not be that easy for him any more:) He seems a nice guy, but, too easy imo. Same with Carbide one.
09:30 PM LeelooMinai: Probably they will come up with anti-net devices - maybe some wire-like protrusions connected with wires, so the net cannot reach the weapon.
09:30 PM Valen: entanglement devices have been banned for pretty much the life of the sport, it's going to be interesting and perhaps boring
09:31 PM LeelooMinai: Well, I don't know - seems a fair game to me. If you use one, you will have probably one-shot only.
09:32 PM LeelooMinai: They are also pretty specific and specialized, so unlikely to overpower everything like spinners.
09:35 PM LeelooMinai: Would be fun to rewind to Robot Wars 2050 though.
09:36 PM * LeelooMinai rewinds and sees robots in the audience watching people smash each other with clubs
09:56 PM Tom_itx: that's called LA
09:58 PM LeelooMinai: Hmm, I have torque wrench and cannot use it because I lost the silly 1/2 to 3/8 adapter thingy - that sucks
09:59 PM LeelooMinai: I cannot find anything in my room any more - maybe it's a sign I should organize it.

11:55 PM Crom: portable walking foot...
11:57 PM roycroft: i was going to work on leveling my lathe this evening, but found that i don't have any thin shim stock in steel
11:58 PM roycroft: and i don't think it would be good to use brass for that
11:58 PM roycroft: so i've ordered some steel shim stock
11:58 PM Crom: got a crate of feeler guages?
11:58 PM roycroft: i don't have any sacrificial ones
11:58 PM roycroft: i think brass might compress and spread out over time
11:59 PM roycroft: the stuff i ordered is hardened 1018 in thicknesses ranging from 0.001" to 0.015"
