01:44 AM -!- #linuxcnc mode set to +v by weber.freenode.net
02:36 AM Loetmichel: mornin'. Meh, barely 1.5h at the company, already thinned the skin on my fingers. That Caustic soda developer is a mean sauce... maybe i should wear gloves when patting around in that goo... anyways, last frontpanel-lettering done! (hopefully) :-)
02:40 AM rmu: Loetmichel: how are you doing it? photoresist and etch? how do you image and expose the photoresist?
02:43 AM Loetmichel: the material is called "alucorex", photoresist-clad anodized aluminium
02:43 AM rmu: oh, ok. never heard of it. bungard?
02:44 AM Loetmichel: same process as making PCBs (iE: printing a foil, putting it on the alucorex, expose to UV for a few minutes, throw in the developer), just that the developer is also the "etchant" for the anodizing/alu
02:44 AM Loetmichel: yes
02:45 AM rmu: so the anodizing is colored black and the NaOH etches exposed material?
02:45 AM Loetmichel: yes
02:46 AM Loetmichel: the NaOH develops the photoresist and then continues to etch away the black anodizing until you can see the writing
02:47 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=669
02:47 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=681
02:47 AM Loetmichel: these i made a few years ago
02:47 AM Loetmichel: thats 1mm alucorex
02:48 AM rmu: interesting.
02:50 AM rmu: and the template is a laser-printed transparent sheet?
02:50 AM Loetmichel: yes
02:51 AM rmu: I never had very much success with that method when making PCBs, toner usually wasn't dense enough and traces became "spongy"
02:52 AM rmu: and accuracy of my laser printer wasn't good enough, but i guess that's less of an issue with front panel lettering
02:52 AM Loetmichel: try to get a HP laserjet 4+ or similar age printer
02:52 AM Loetmichel: they put enough toner on the paper to make it waterproof ,)
02:52 AM rmu: no thanks, but no ;)
02:53 AM rmu: laserjet4+ is about early 90ies?
02:53 AM Loetmichel: yes
02:54 AM Loetmichel: im have one thats done a million pages... still running like new :-)
02:54 AM rmu: i remember having a beast like that at work back then, some poor HP service guy had to disassemble and vacuum it on a bi-weekly basis, while it did print about 200 pages between services
02:55 AM rmu: HP stands for Horrible Printer
02:56 AM Loetmichel: back then the print engines were made by Canon.
02:57 AM Loetmichel: laserjet 4+ has the same engine as canon lbp8-IIIt
02:57 AM Loetmichel: and they work like a charm ;)
02:59 AM rmu: maybe that specimen was a dud. the "Horrible Printer" label was earned later.
04:18 AM veegee: Damn
04:18 AM veegee: I put too much grease in the gears in my right angle die grinder
04:19 AM veegee: somehow the grease went into the pneumatic motor section
04:19 AM XXCoder: ow. rebuild time
04:19 AM veegee: I can see small amounts of red lithium grease coming out the exhaust
04:19 AM XXCoder: greased air ;)
04:19 AM veegee: But I flooded it with air tool oil and ran it with a high oil drip rate for a while
04:20 AM veegee: It ran just fine and flushed out most of the grease
04:20 AM veegee: What's the worst that can happen?
04:21 AM veegee: I have a air line lubricator set to 1 drop every 5 seconds for that tool right now
04:21 AM veegee: Can't notice any change in performance or noise from the motor. Gears got a lot quiet though
04:21 AM JavaBean: don't let the tool exhaust at your body
04:21 AM veegee: JavaBean worst case you get a light coating of clean air tool oil
04:22 AM veegee: not a big deal
04:22 AM JavaBean: some people might have a reaction to it... also makes you more flamable
04:22 AM veegee: Not really
04:22 AM veegee: You can drop a flaming match into a bottle of air tool oil and the match will go out
04:22 AM veegee: point a blowtorch into it and it'll just smoke
04:23 AM veegee: Same thing with kerosene. They're waaaaayyyyy too thick
04:23 AM JavaBean: try your test again, with a "light coating of clean air tool oil"
04:23 AM Loetmichel: or diesel
04:23 AM Loetmichel: thick isnt the point, low vapour pressure is
04:23 AM veegee: light coating of oil on skin with grinding sparks?
04:23 AM Loetmichel: you can only light vapors
04:24 AM veegee: yeah low vapour pressure
04:24 AM veegee: light coat of oil on skin with grinding sparks was my entire day today
04:24 AM veegee: only thing that started burning was the steel wool I had beside what I was grinding for cleaning purposes
04:24 AM JavaBean: my point is, that light coating of oil on clothes may be more flamable than the clothes when clean
04:24 AM veegee: probably the other way around
04:25 AM veegee: depending on the ignition sourc e
04:25 AM veegee: grinding sparks have very low energy, not enough to raise the local temperature of an oily rag
04:26 AM veegee: but maybe enough for clean dry cotton, which is what you can use to start a fire by rubbing wood together
04:26 AM JavaBean: beeswax doesn't burn well at low temps... but if there is a wick in it, the wick will burn and consume the beeswax
04:26 AM veegee: yeah neither of those is easy to ignite
04:26 AM XXCoder: wick is accerant for it heh
04:26 AM veegee: the wick alone will ignite even easier is my point
04:27 AM XXCoder: exactly my point, yeah. it burns and heats things enough so harder to burn wax burns
04:27 AM veegee: well also increases temperature which increases vapour pressure
04:27 AM veegee: it's burning a vapourized oil in the wick
04:28 AM veegee: so I'm not worried about getting sprayed with a very light coat of oil
04:28 AM veegee: also have lots of fire extinguishers around
04:28 AM veegee: Also I wear leather welding protective equipment when I grind anyway
04:29 AM veegee: It's actually really hard to set things on fire
04:29 AM veegee: I tried last night on my neighbour's house. Waste of a bottle of popane
04:29 AM veegee: Even poured diesel fuel on it. Nothing
04:35 AM Loetmichel: JavaBean: actually: the wick will NOT burn
04:36 AM Loetmichel: it will just wick up the molten wax into the flame where it vaporizes
04:36 AM Loetmichel: zippos are known to have glass fibre wicks wich cant burn, they work just fine, even with diesel oil
04:36 AM JavaBean: i had a bunch of candles where the wick is totally burnt up and are gone
04:37 AM Loetmichel: you just have to have enough "ignition" energy to vaporize a tiny bit of fuel, ignite it and it will start a "runaway reaction"
04:38 AM Loetmichel: wicks in candles only burn once there is no more fuel aviable to wick on or the fuel is to cold to vaporize (i.E: initial lighting of a candle until there is liquid wax)
04:39 AM Loetmichel: the moment there is fuel to vaporize the wick will be cooled by said vaporizing and not burn any more
04:39 AM * JavaBean shrugs, points out that when he lights a candle he lets it burn for a few hours
04:41 AM Loetmichel: yeah, thats what i meant. The wick only burns when its either "dry" or to long to wick up the wax to the top
04:41 AM Loetmichel: hence candles roughly always having the same length of wick sticking out, regardless of how short the candle already is.
04:42 AM JavaBean: not really in my case, i trim the wick before lighting
04:42 AM Loetmichel: when you use a hot air gun/bunen burner to carefully melt the wick/wax before lighting it you can have a nearly white wick with a burning flame on it.
04:43 AM Loetmichel: then your wick doesent burn without residue
04:43 AM Loetmichel: or its sized wrong for the candle (a.k.a can wick up further than the flame size you want to have)
04:44 AM Loetmichel: there is a point for every candle/wick compbination where it will gracefully burn down to the end with the wick "self shortening" as it goes down
04:55 AM JT-Cave: morning
05:29 AM * JT-Cave candles every day but has no candles
06:19 AM Tom_L: morning
06:23 AM XXCoder: hey
07:43 AM JT-Cave: hi ho... hi ho it's off to the shower I go to start my day
07:43 AM XXCoder: yay
08:24 AM roycroft: it is friday
08:24 AM roycroft: this is good
08:25 AM CaptHindsight: Loetmichel: you can use an inkjet to put graphics into anodize
08:27 AM CaptHindsight: anodize but not seal the aluminum, print with solvent dye ink, seal, done
08:29 AM CaptHindsight: if you don't have a flatbed inkjet than you also make stencils and just spray solvent ink
08:32 AM CaptHindsight: https://imgur.com/a/yAITRos
08:34 AM CaptHindsight: also works for anodized aluminum plated cold roll https://imgur.com/a/N0l5O96
08:35 AM CaptHindsight: 1.5mm steel ^^
08:48 AM Loetmichel: CaptHindsight: its ready made 1mm alu sheet already anodized and then clad with photoresensitive resist.
08:49 AM Loetmichel: -re
08:49 AM Loetmichel: https://www.bungard.de/en/consumables/consumables/alucorex
09:01 AM tiwake: hmm, I think its sodium hydroxide that is good at stripping anodize?
09:01 AM Loetmichel: NaOh, indeed
09:02 AM Loetmichel: 8g on a liter hot water is sufficient
09:02 AM CaptHindsight: strong alkalines
09:03 AM CaptHindsight: powdercoat + laser also works on any metal
09:11 AM Loetmichel: tiwake: its meant to make durable front panels/manufacturer plates
09:11 AM Loetmichel: hence the photoresist
09:11 AM Loetmichel: that the developer for the photoresist and the etchant for the anodizing is the same stuff is just a bonus ;)
09:16 AM CaptHindsight: also cleans the drain
09:22 AM Loetmichel: indeed
09:22 AM jymmmm: morning
11:30 AM Tom_L: jym, it probably was zhanx
12:24 PM satiowadahc: Finally figured out how to register... Do people use the web client or is there a desktop app for freenode?
12:25 PM roycroft: i use a curses-based client
12:26 PM roycroft: so none of the above :)
12:29 PM satiowadahc: Through the terminal?
12:37 PM Tom_L: satiowadahc, hexchat is a good one
12:37 PM Tom_L: runs on just about anything
12:41 PM satiowadahc: Thanks! I'll check it out
12:42 PM Tom_L: glad you're here and willing to help out. we need developers
12:42 PM satiowadahc: We're a team of three, and trying to convince upper management to spend time on the main project so we can give back ... finally :P
12:43 PM Tom_L: have you seen the additional qtpyvcp gui additions?
12:44 PM satiowadahc: Are you talking of : https://github.com/kcjengr/qtpyvcp/ ?
12:44 PM Tom_L: yes
12:45 PM Tom_L: #hazzy is their main channel
12:45 PM * hazzy-m was summoned
12:45 PM Tom_L: meh, go back to sleep
12:49 PM satiowadahc: uffdah. IRC has a lot of channels. So if I'm understanding it right its seperate from lcnc but still has the 2-3 issues?
12:51 PM hazzy-m: satiowadahc: QtPyVCP is a framework for building GUIs for LinuxCNC
12:59 PM satiowadahc: Ah yes, looking at it we pulled a few oddballs from there into our gui
01:55 PM skec: Hi guys, may I ask, if there is a way in linuxcnc to move stepper motor one step? not 1 mm, or 0.01 mm, but 1 step. I ask this, because I want to know how many steps per revolution there is in my dvd rom stepper motor. This information I need to calculate the SCALE parameter. I guessed that there is 20 steps/rev, however, with this, when I move 5
01:55 PM skec: mm in linuxcnc, I get 2.5 mm of actual move (through leadscrew).
01:57 PM JT-Shop: hook step to direction pin and change direction
01:58 PM skec: my configuration is using step_gen=7, its not step/dir, but 4-phase thing..
01:59 PM JT-Shop: then you would need to know steps per rev or guess at it I assume as I've never done a 4 phase stepper
02:00 PM W1N9Zr0: set SCALE to 1, then 1mm move = 1 step
02:00 PM skec: awesome W1N9Zr0! thanks!
02:42 PM X704 is now known as tiwake
02:48 PM Centurion-Dan2 is now known as Centurion_Dan
02:48 PM roycroft: were that 3 o'clock would arrive soon
02:48 PM * roycroft is decidedly done with work for the week, but is not off work for another two hours and 15 minutes
03:02 PM JohnS_AZ: Hi guys. I'm putting together my first machine and just got it moving last night. Now I'm at the limit and home switches point. I see I can wire all of the limits to one input, and all of the homes to one input. OR, I can use the limits AS homes, and wire things up per axis. I can see where the second would save a bit of wiring, but aside from that
03:02 PM JohnS_AZ: is one approach better than the other?
03:03 PM Deejay: gn8
03:04 PM JT-Shop: limit and home can be the same switch on each axis
03:05 PM JT-Shop: just set the ini file for each axis that has a shared switch
03:05 PM JT-Shop: roycroft, hows the bench coming along?
03:08 PM roycroft: jt-shop: i fitted/tested the leg vise hardware yesterday
03:08 PM roycroft: i'm going to start cutting the tenons for the stretchers and bench top support after work today
03:08 PM roycroft: hopefully i'll do the first dry fitting of the base this weekend
03:09 PM robotustra: JohnS_AZ, what controller do you use?
03:09 PM roycroft: i still have a *lot* of work to do, but i'm making progress every ay
03:09 PM roycroft: day
03:09 PM roycroft: the vise installation yesterday was awesome
03:10 PM roycroft: people have made videos of spinning the vise wheel with one finger and having it close all the way, tightly
03:10 PM roycroft: and i am able to do that
03:10 PM roycroft: i'm feeling a lot better about having spent $700+ on vise hardware after that test fitting :)
03:10 PM JT-Shop: sweet
03:12 PM JohnS_AZ: robotustra, I'm using a salvaged 3-axis mechanism, so I'm using the 5-phase step/dir controllers that came with it. ( https://twitter.com/JohnS_AZ/status/1293242207068024833 )
03:13 PM robotustra: JohnS_AZ, sorry, twitter is a negative technology I dont use
03:13 PM robotustra: as well as fb
03:17 PM robotustra: JohnS_AZ, I mean what software and interface board?
03:17 PM robotustra: to spell your G-code?
03:18 PM JohnS_AZ: I curate my twitter as a tech/geeks only space. Quite a valuable/fun channel.
03:19 PM JohnS_AZ: I'm not there yet. Just have LinuxCNC (using the example files) running the machine through OrientalMotor PMC controllers. https://www.orientalmotor.com/products/pdfs/opmanuals/HP-7420-4E.pdf
03:21 PM JohnS_AZ: I'll probably just use one switch per axis for simplicity's sake, but was wondering if the other approaches are considered "better".
03:22 PM robotustra: yeah, the simpler solution the most relyable it will be
03:22 PM robotustra: less wiring
03:23 PM robotustra: less points of failure. I used my device for many years without limit and home switches
03:24 PM JT-Shop: roycroft, I watched a video the other morning of the split top table and it's pretty cool
03:24 PM robotustra: I would put only necessary switches like on 3d printers
03:25 PM JohnS_AZ: *nod* Thanks
03:28 PM robotustra: for nothing
03:29 PM robotustra: to make something better you need to have at least the first prototype
03:30 PM robotustra: working somehow
03:39 PM CaptHindsight: JohnS_AZ: what machine are those out of? Some sort of printer?
03:40 PM CaptHindsight: Belt drive. Is this for non contact deposition or for very light cutting?
03:45 PM JohnS_AZ: It was some sort of medical lab device that dispensed liquids into vials through a 3" hypodermic needle. So, yeah, this is a pretty low torque machine. That's why I'm only using it as a pen plotter.
03:46 PM JohnS_AZ: This fall I'll be building a large lead screw based machine (when my shop cools off). Just using this as an educational machine to learn all of the software.
03:49 PM JohnS_AZ: (this could, however, be turned into a cool little pick and place machine) :-)
04:11 PM CaptHindsight: print DNA, deposit silicone or radcure resins, bioplotter etc
04:36 PM robotustra: if it's low torque motors I would just place hard stops and didnt even think about limit switches
04:38 PM satiowadahc: Would you just let it torque out and detect a stall then as your home?
04:39 PM robotustra: no, it will just lose steps at hard stop
04:40 PM robotustra: but after hard stop make G10 command and homing is done
04:41 PM robotustra: for weak motors it could be a solution
04:52 PM JohnS_AZ: Could. But since this is a model for a larger machine I want to build I want it to have pretty much the same system.
04:56 PM CaptHindsight: it's a Cartesian system with steppers
04:59 PM CaptHindsight: limit switches are simple to add and the config file changes is only a line or two, so pretty close with or without
05:00 PM roycroft: it's the weekend!
05:01 PM * roycroft can finally get some real work done
05:01 PM JohnS_AZ: Well, I was a manufacturing engineer ... 'drive it into the stops and call it zero' just doesn't sit well with me. :-)
05:01 PM CaptHindsight: so add limit switches
05:02 PM CaptHindsight: roycroft: sour tasting?
05:02 PM JohnS_AZ: I am ... one per axis.
05:02 PM roycroft: no, that's after work entertainment :)
05:02 PM roycroft: i'll be cutting tenons for my workbench base presently
05:02 PM CaptHindsight: I'll likely be sanding, sanding and then sanding
05:03 PM CaptHindsight: after that some sanding, with a little painting in between
05:03 PM CaptHindsight: they should not call it a paint job, it should be called a sanding job
05:27 PM roycroft: i have sanding, sanding, and sanding coming up in the not too distant future
05:30 PM robotustra: JohnS_AZ, are you manufacturing engineer or manufacturing overengineer?
05:31 PM robotustra: it's better spend the time on real machine than on mock up
05:36 PM Tom_itx: this from the one that still has an unfinished lathe :)
05:41 PM JohnS_AZ: Yeah. Well, Mr. negative technology.
05:59 PM roycroft: "negative technology" is a really polite way of referring to those cesspools :)
06:00 PM roycroft: that said, there is a lot of value in doing mock-ups/proofs of concept
06:00 PM roycroft: moving onto production without prototyping is, well, brave
06:01 PM roycroft: and not the good kind of bravery
06:01 PM JohnS_AZ: Remarkably diplomatic. :-)
06:01 PM JohnS_AZ: Not my strong suit. :-)
06:03 PM JavaBean: Winston Churchill — 'Tact is the ability to tell someone to go to hell in such a way that they look forward to the trip.'
06:08 PM CaptHindsight: something has triggered wounded souls recently, lots are out today
06:31 PM robotustra: Tom_itx, I was busy with making guards for manual mill
06:32 PM robotustra: soon come back to the lathe
06:34 PM robotustra: when I started to mill on a man mill, I got a lot of chips on the floor, which are finally appear all over the appartment
06:34 PM robotustra: not, good
06:35 PM robotustra: btw, got pulleys for powerfeed
06:35 PM Tom_itx: nice
06:42 PM robotustra: did i show the prototype of powerfeed?
06:42 PM Tom_itx: i dunno
06:43 PM robotustra: https://imgur.com/a/G8z5vKP
06:48 PM robotustra: but for this one I must add end stops :)
06:53 PM robotustra: but I burned accidently arduino, 5v dcdc and encoder
06:53 PM robotustra: fortunetely, not a motor driver
06:54 PM robotustra: short circuit 36v to 5v
06:55 PM robotustra: ordered new ones
06:55 PM JohnS_AZ: Cool. Is that running on a nano?
06:57 PM robotustra: micro
06:58 PM robotustra: i like atmega 32u4 it has ISP pins ind Spi puns too
07:00 PM robotustra: it means that I can remove bootloader and make it simple atmega after debug
07:02 PM robotustra: nano is 3.3 v and cpu works at 8 mhz I guess
07:02 PM robotustra: micro is 5v and 16mhz
07:08 PM JohnS_AZ: Cool. I prefer to use straight PIC micros, but have plenty of Arduino and Pi boards around here.
07:08 PM JohnS_AZ: The knob is SPI?
07:09 PM robotustra: no, knob is usual encoder, A+ A- B+ B-
07:09 PM robotustra: and Vcc and GND
07:10 PM robotustra: it's attached to interrupt pin and counts ticks
07:10 PM robotustra: and direction
07:10 PM JohnS_AZ: Nice. I've used plenty of shaft encoders, but I've never seen the cool knob. :-)
07:10 PM robotustra: plenty of them on ebay
07:10 PM robotustra: it's about 20-30$
07:11 PM robotustra: but unfortunately it's not disasseblible
07:11 PM robotustra: 100 ppr
07:12 PM robotustra: I want to use it as powerfeed in 2 modes, stepped mode and continuous
07:14 PM robotustra: on a usual grizzly powerfeed they use resistor and switches
07:16 PM robotustra: I decided that to rotate encoder is much easier than a manual wheel
07:17 PM JohnS_AZ: I presume this is on a mill
07:18 PM robotustra: yes
07:19 PM robotustra: I got grizzly-like mill
07:19 PM robotustra: KC-20
07:19 PM robotustra: like g0704
07:19 PM robotustra: and what to make powerfeed more compact that standard
07:20 PM robotustra: I just don't have extra space for it
07:20 PM robotustra: 8-10 inches I think
07:25 PM JohnS_AZ: Nice machine
07:26 PM robotustra: yes pretty solid, but need a lot of upgrades out of the box
08:44 PM jymmmm: Tom_itx: ping?
08:46 PM Tom_itx: jymmmm, pong
09:11 PM skunkworks: The timing belt drives looks like it should work good.
09:17 PM Tom_itx: yay
09:17 PM Tom_itx is now known as Tom_L
09:17 PM Tom_L: i'm working on some custom threads to test
09:18 PM skunkworks: need to get the pid and scaling right now..
09:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cup4.JPG
09:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cup1.JPG
09:19 PM skunkworks: cool!
09:20 PM robotustra: Tom_L, are you going to lathe it or mill?
09:20 PM robotustra: I mean threads
09:21 PM robotustra: I ordered a thread mill to try make big thread on my router
09:21 PM robotustra: like this one https://www.ebay.com/itm/1-4-20-56-TPI-SINGLE-PITCH-THREAD-MILL-BRAND-NEW-TiALN-COATED/351681186689
09:21 PM skunkworks: needed a little more machining to get the spacing right - but I can also use 1 belt size for both speeds
09:22 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200816_143641.jpg
09:23 PM robotustra: skunkworks, what is the machine?
09:24 PM robotustra: you bolted aluminium pulley to the steel hub? I will need to do something similar
09:24 PM Tom_L: mill
09:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
09:26 PM robotustra: nice, will you write g-code manually for that?
09:26 PM Tom_L: i wrote a macro to generate the threads in my cad cam
09:26 PM _unreal_: milling a replacement part for my drillpress right now
09:27 PM robotustra: I'll need to do something similar
09:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin.jpg
09:28 PM robotustra: but I think it's just a subroutine with parameters
09:28 PM Tom_L: it will generate internal or external threads
09:28 PM Tom_L: right or left hand
09:29 PM robotustra: 3 pathes?
09:29 PM Tom_L: you can choose now many you want/need
09:29 PM Tom_L: 1 to x
09:29 PM robotustra: what is the language of macro?
09:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/ThreadMill_Multi_arc.mcl
09:30 PM Tom_L: it's a script of some sort
09:30 PM robotustra: oh, it'a just a fortran
09:31 PM robotustra: with while
09:32 PM robotustra: pretty similar grammer
09:32 PM Tom_L: it's pretty old cad but it works good
09:35 PM robotustra: I do mainly 2d simple parts, for which I can write code manually
09:35 PM robotustra: may be for 3d I still will be using artcam

09:37 PM _unreal_: Part for my drill press. original was plastic I'm making a new one ut of aluminum
09:37 PM Tom_L: alot of times i'll use catia to draw a 3d model and bring it into my cad cam
09:38 PM Tom_L: same as i did it when i bought the package
09:38 PM Tom_L: most companies we dealt with used either catia or cadam
09:38 PM robotustra: does catia costs money?
09:39 PM Tom_L: lots
09:39 PM Tom_L: more than solidworks
09:39 PM _unreal_: I like designspark machanical
09:39 PM _unreal_: its free and super powerful
09:39 PM _unreal_: oh TOM they just added some new features to it like equation drawing
09:40 PM Tom_L: it's got stuff in it i'll never use but i took a few classed on it and like it
09:40 PM Tom_L: _unreal_, i've done functions and table driven parts
09:40 PM robotustra: _unreal_, to mill your parts you need to flip it
09:41 PM robotustra: 2 sides milling
09:41 PM Tom_L: why?
09:41 PM Tom_L: put a couple tabs on it and mill it
09:42 PM robotustra: there is an undercut for bolt ear
09:42 PM Tom_L: ahh, i didn't see that
09:42 PM _unreal_: that part I just showed is a two sided one
09:43 PM _unreal_: I need to make a pocket to flip it into so I can mill the relief on the other side
09:43 PM _unreal_: onlything I cant do on mymill is make the mold hole that clamps it
09:43 PM Tom_L: not enough clearance?
09:45 PM robotustra: clearence on a router is quite annoying thing, I have like 4" and it's samll for vise and big when I mount flat part on a table

09:50 PM Tom_L: alot stiffer than plastic
09:50 PM Tom_L: i made 2 pairs of em
09:52 PM skunkworks: robotustra: a little emco compact 5
09:53 PM robotustra: I think you have spent on aluminum more than the scate costs in walmart
09:53 PM Tom_L: naw
09:53 PM Tom_L: surplus, it's fairly cheap
09:54 PM robotustra: skunkworks, cool, I would buy that but I don't have it around montreal
09:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/stock_index.php
09:55 PM robotustra: I don't know what does it mean. You mean it's chipo material
09:55 PM robotustra: ?
09:55 PM robotustra: how much chuchu your scate costs finally?
09:55 PM Tom_L: cutoff companies didn't use

09:57 PM Tom_L: these were cheap compared to the pair he got after that
09:58 PM robotustra: what about wooden top?
09:59 PM robotustra: skunkworks, ACME threads, do you have backlashes?
10:02 PM robotustra: skunkworks, you are ahead of me with comparison to my lathe build

10:03 PM satiowadahc: interesting... freenode doesn't persist logs after you close it
10:04 PM Tom_L: hexchat does if you turn logs on
10:04 PM skunkworks: robotustra: ball screw
