01:34 AM * gloops checks the 'jobs left to do list'
01:41 AM gloops: which is more like - jobs to do again list
02:06 AM Deejay: moin
02:06 AM gloops: morning
04:17 AM jthornton: morning
04:18 AM XXCoder: yo
04:23 AM jthornton: wow it's 52°F
05:21 AM Isleape1 is now known as Isleape
05:59 AM gloops: https://www.ebay.co.uk/itm/Inventables-Shapeoko-2-3-Axis-CNC-Cutting-Router-Engraving-Milling-Machine/263449607275?
05:59 AM gloops: cheapo router going uk
06:00 AM gloops: 60z motors, doubtful that has much practical use
06:01 AM archivist: er "small engraver"
06:03 AM gloops: it looks deceivingly bigger in the photos, yes its probably better called an engraver
06:03 AM archivist: I wonder if that seller is making them, I see no "use" marks
06:04 AM gloops: shapeko is a brand i think, theyre on to shapeko 3 or 4 now
06:04 AM gloops: https://www.ebay.co.uk/itm/cnc-3-axis-woodwork-router-plasma-cutter-machine-5ftx3ft/182647702537?
06:05 AM gloops: thats probably more in the class of what im trying to make, more powerful, probably not as rigid at a guess
06:07 AM archivist: for that much money I expect some covers for the screws
06:09 AM gloops: wiring and such looks a tidy job, some decent parts in it, not sure how you would cover the screws?
06:09 AM gloops: bellows or retracting blinds or something
06:09 AM gloops: they are mainly out of the blast area, with dust hose shouldnt get too much on them
06:11 AM phipli: hum
06:11 AM phipli: one of the chickens is looking sorry for herself today
06:11 AM phipli: looks like she's stuffed herself with wood chippings because shes stupid and greedy
06:13 AM gloops: may need worming phipli?
06:14 AM phipli: she's just greedy
06:14 AM phipli: always has been
06:14 AM phipli: they broke an egg
06:14 AM phipli: and ate it
06:14 AM phipli: (they don't usually, was probably thin shelled)
06:14 AM phipli: but I've seen her do it before
06:14 AM phipli: she eats the egg flavoured chippings
06:15 AM phipli: then looks really put out that it makes her feel funny
06:15 AM gloops: lol
06:16 AM gloops: well a bit of roughage probably wont hurt
06:16 AM phipli: I don't like when they stop eating though
06:16 AM phipli: it can be a really bad sign
06:18 AM gloops: yeah better to keep an eye on them when theyre like that
06:18 AM phipli: yeah
06:18 AM phipli: going to catch her in a bit and check her over
06:18 AM phipli: offer her some treats to get some food in her
06:19 AM phipli: check her crop etc
06:19 AM jthornton: morning phipli
06:22 AM jthornton: http://gnipsel.com/images/chickens/chickens/01-26-18.jpg
06:22 AM jthornton: the USB camera http://gnipsel.com/images/chickens/nestbox/nest-box-cam-03.jpg
06:36 AM * fragalot just finished breaking in his spindle
06:36 AM jthornton: that's not good
06:36 AM fragalot: not checked run-out on it yet though
06:39 AM phipli: crop is fine
06:39 AM phipli: isn't doing "eggbound" movements
06:39 AM phipli: takes grain from me
06:39 AM jthornton: what is "eggbound" movements?
06:39 AM phipli: just... depressed
06:39 AM phipli: if she was eggbound she'd be squatting
06:40 AM phipli: and sort of trying but failing to lay an egg
06:40 AM phipli: probably her rear feathers moving back like she was going to poo
06:40 AM phipli: is that your Henry?
06:40 AM jthornton: I know that sign well...
06:40 AM phipli: He's all grown up
06:40 AM jthornton: yes, he has decided to be my friend
06:41 AM phipli: :)
06:41 AM phipli: and who's the young lady next to him?
06:42 AM jthornton: she doesn't have a name yet, only two of the RIR pullets stand out with comb features
06:43 AM jthornton: she was sitting on my legs and Henry hopped up, I put my hand on his back and he squatted down with no indication he didn't like it
06:44 AM phipli: One of our new ones is properly relaxed with us now
06:44 AM phipli: the other... is scared of her own shadow
06:44 AM jthornton: nice
06:45 AM jthornton: that makes it hard to get them comfortable with you
06:46 AM phipli: yeah - I don't want to push my luck and drive her away
06:46 AM fragalot: ._. I give up with this FUsion360 model
06:47 AM fragalot: maybe I should just make my mill out of wood first & work out the mold for the granite version from there
06:47 AM jthornton: i wish I could get this over here https://www.modmypi.com/raspberry-pi/cases-183/raspberry-pi-b-plus2-and-3-cases-1122/nwazet-pi-camera-box-bundle-case,-lens-and-wall-mount-b-plus
06:58 AM jthornton: https://www.amazon.com/Raspberry-Starter-Official-Case-Power-Supply/dp/B0787BXR3P
06:58 AM jthornton: I wonder if the top cover with the round hole will fit a camera?
06:59 AM * fragalot runs off to the shops to buy a pile of crappy plywood to build a mill mock-up
06:59 AM fragalot: 18mm ply, or 20mm tooling plate.. Essentially the same thing, right? xD
07:16 AM phipli: jthornton, I have one somewhere, I'll check
07:16 AM phipli: I think that is what it is for
07:16 AM phipli: jthornton, we now have two chickens in one nestbox, arguing while they try to lay eggs
07:17 AM phipli: (the nest boxes aren't big enough for two chickens)
07:17 AM jthornton: I've had 3 in the Mk2 24" wide box... now with the Mk3 36" wide box I seldom see more than 2 in there
07:19 AM phipli: jthornton, that cover with a hole in it is for the camera
07:19 AM phipli: has four clip/pins on the reverse that clip into the screw holes on the official camera board
07:20 AM jthornton: cool, I think that will be a better nest box camera being very small
07:21 AM jthornton: I got a 10,000mah USB battery pack to power it
07:21 AM phipli: it is approximately 3x1.5 inch
07:21 AM phipli: (my parents got me one a while back)
07:22 AM jthornton: the one I built with the POE splitter ended up being in a 200x120x75mm case so pretty big
07:25 AM jthornton: 3 eggs in the roll out nest box but it's raining
07:26 AM phipli: https://zdnet3.cbsistatic.com/hub/i/r/2017/05/07/875c87b9-5860-40b0-a521-be82ca840dbe/resize/370xauto/62547c6d3493fbbd40c01181f6cbc4be/imgp3774.jpg
07:26 AM jthornton: I have a month left on this machine build and I got another job yesterday for right after I'm done
07:27 AM phipli: that the polisher?
07:27 AM jthornton: nice
07:27 AM jthornton: yes
07:27 AM phipli: better picture : https://pbs.twimg.com/media/C5xjuzUWcAAwW5_.jpg
07:28 AM jthornton: I had a HMI go out on a machine and the replacement was not compatible so I had to write a new program from scratch
07:28 AM phipli: remember that there isn't any ethernet
07:28 AM jthornton: I thought the new zero W had wifi built in?
07:28 AM phipli: yeah
07:28 AM phipli: but no ethernet
07:29 AM phipli: I thought your existing system was ethernet based :)
07:29 AM jthornton: right, I'm going to try to connect with wifi
07:29 AM phipli: good good
07:29 AM jthornton: I have wifi switches all over the place lol
07:29 AM phipli: what sort of thing did you have to do for the HMI?
07:32 AM jthornton: I had to write a new program for it at the same time learn about Maple Systems HMI software took quite a while
07:32 AM jthornton: translates into I made a lot of money this week :)
07:34 AM phipli: Excellent :)
07:35 AM phipli: My old boss was saying he gets his pension half way through the month, and payment for any part time work at the end of the month
07:35 AM phipli: sounds... like two paydays
07:36 AM Tom_L: 29�F
07:37 AM gloops: found a reamer thats a perfect size for stepper motor shafts, in box of old imperial stuff, what a stroke of luck
07:44 AM phipli: Will never understand why these are so expensive
07:44 AM jthornton: what's that?
07:45 AM phipli: at some point I'd like to get something like this for my nephew + niece (distant future)
07:45 AM phipli: educational microprocessor board
07:45 AM phipli: sort of things schools (should) use for teaching kids embedded programming
07:46 AM phipli: usually come with a book of projects to learn how to do things like, read the temperature from a DS18b20 and display it on a 1602 LCD
07:46 AM phipli: the cost... compared to the bits... is insane though
07:47 AM phipli: I understand educational materials / software / videos cost money
07:47 AM phipli: but I can't help but feel they're wasting money for their custom IDE that you don't need, and only works on windows anyway
07:52 AM jthornton: got a link to it?
07:53 AM Tom_L: you just lookin for a camera case for the pi?
07:53 AM phipli: https://www.ebay.co.uk/itm/DEV-BOARD-EASYAVR-V7-MIKROE-2013-Fnl/352066808393
07:54 AM phipli: forgot I hadn't linked sorry :)
07:54 AM phipli: My older version came out of a discount bin, and didn't have all the peripherals
07:54 AM phipli: best way as you can pick up a 1602 display for £0.99
07:57 AM jthornton: Tom_L: looking for a smaller package for the rpi camera yes so a zero and case will fit the bill
07:57 AM jthornton: hmm I think I have the rt kernel installing on jessie :)
07:57 AM Tom_L: looked on thingiverse?
07:57 AM jthornton: yes that is pricey for sure
07:58 AM jthornton: https://www.amazon.com/gp/product/B0748MPQT4
08:07 AM phipli: http://cpc.farnell.com/phoenix-contact/rpi-bc-107-6-dev-kit-kmgy/din-rail-raspberry-pi-bc-dev-kit/dp/EN8496869
08:07 AM phipli: DIN raspberry pi cases discounted
08:08 AM Tom_L: https://grabcad.com/library/orange-pi-zero-case-for-35mm-din-rail-1
08:09 AM Tom_L: https://grabcad.com/library/raspberry-pi-zero-casing-1
08:10 AM jthornton: cool
08:10 AM phipli: Tom_L, costs a little more when you have to buy the printer first :)
08:10 AM jthornton: 5 eggs in the nest box and still raining
08:11 AM Tom_L: he has one
08:11 AM phipli: jthornton, I should check it those two birds sat on each other have laid anything
08:13 AM jthornton: wow 2.2 extra GB of data
08:13 AM phipli: left, or they've given you more?
08:13 AM jthornton: I've just not used it yet
08:14 AM Tom_L: you sorta feel obligated when they set a limit...
08:14 AM jthornton: no need to be frugal with my data for the rest of the month
08:14 AM jthornton: yea download videos all day long lol
08:15 AM phipli: :)
08:15 AM Tom_L: got the Z column fairly square and did the Z offset last evening
08:16 AM Tom_L: need to drill holes for the spindle mount now and recheck it all
08:21 AM jthornton: your making more progress than I am with the cleaner I'm building
08:55 AM Tom_L: got the config fairly well tuned to this machine now
08:56 AM Tom_L: moved the control and monitor to the wall above the steel work table now
09:07 AM jthornton: biggest egg yet 76g
09:09 AM Tom_L: what's the tumbler for? parts or rocks?
09:13 AM jthornton: nails
09:32 AM gloops: archivist pity a bit far away https://www.ebay.co.uk/itm/3-inch-Bench-Belt-Sander/173114468649?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
10:03 AM archivist: a few miles down the road!
10:05 AM archivist: I am using my hand held lidl belt sander upside down
10:09 AM Cromaglious_: finally bought a z table for my laser cutter
10:09 AM phipli: where is Hungerford?
10:10 AM Cromaglious_: maybe now, I'll find time to put the tubein, and replumb it fo the radiator
10:10 AM phipli: only 140 miles...
10:10 AM phipli: bit tricky on the bike
10:10 AM phipli: especially with a belt sander on the back
10:11 AM phipli: jthornton, Chicken is looking a bit better
10:11 AM phipli: she's eating things other than treats
10:12 AM phipli: even if she isn't 100% (i.e. not shoving the others out the way to get to the food)
10:23 AM JT-Shop: phipli: what do you think was wrong with her?
10:29 AM phipli: JT-Shop, something she ate hopefully
10:30 AM phipli: or perhaps she had a hard time laying an egg
10:30 AM phipli: (too big or too soft)
10:40 AM JT-Shop: I got a 76g egg this morning... biggest one yet
10:45 AM phipli: that is quite big :)
10:45 AM phipli: I need to get some decent scales so I can weigh ours properly
10:53 AM IchGucksLive: hi
10:55 AM phipli: Afternoon IchGucksLive
10:55 AM IchGucksLive: ;-)
10:56 AM phipli: Getting a new laptop at work soon
10:57 AM phipli: need to persuade them to unlock the bios so I can boot it from a usb stick when I want to...
11:23 AM ziper: what is the adjustment screw on the end of a dial indicator for
11:24 AM phipli: if you mean the knob on the end of the control screw thing
11:24 AM phipli: it isn't an adjustment, it is a device for applying a constant torque to each measurement
11:24 AM phipli: so you don't pinch what you're measuring one time, compared to another
11:24 AM phipli: wait, no
11:24 AM phipli: you said dial
11:25 AM Wolf__: bezel clamp?
11:25 AM phipli: I read micrometer somehow
11:25 AM * phipli fails
11:25 AM Jymmm: phipli: If a company locked the bios, I'm guessing they may not make an exception.
11:25 AM ziper: it has a thread cap, and under that is a screw that does something to the spring that loads the plunger
11:26 AM phipli: Jymmm, it isn't locked on my current machine
11:26 AM phipli: but it is on other people's of the model I'm getting
11:26 AM Wolf__: ziper: picture?
11:26 AM Jymmm: phipli: Yeah, "new policy", feel fortunate, blah blah blah
11:26 AM phipli: I'd rather not log a call every time I want to toggle hyperthreading
11:27 AM phipli: find out soon :)
11:27 AM phipli: I'm one of a small number of people to have local admin
11:27 AM phipli: so...
11:27 AM phipli: you never know
11:27 AM Jymmm: phipli: Or, ask them if you can keep BOTH laptops. Most IT don't really do much with older ones except keep around for spares.
11:27 AM phipli: that is the plan
11:28 AM phipli: the old one is a few years old, but was amazing at the time
11:28 AM phipli: 5 or so years old
11:28 AM phipli: but quad core i7 with 8gig of ram and an ssd
11:28 AM Jymmm: Computers are the only thing I know of that are worth thousands new, and worht hundreds in 6 months or less =)
11:29 AM phipli: yeah - the ram in the new machine is worth more than the whole of the old machine
11:29 AM gregcnc: ziper if there is a knob there it's not really an adjustment
11:29 AM Jymmm: phipli: Eh, I'm a ram whore, so that's always the case for me
11:30 AM phipli: I'm using CFD and so have asked for 32gb
11:30 AM Jymmm: CFD?
11:30 AM phipli: Computational Fluid Dynamics
11:30 AM Jymmm: ah
11:30 AM phipli: simulated fluid flow
11:31 AM Wolf__: I have to wonder if he is talking about the knurled top end of the spindle
11:31 AM phipli: for other, non-cfd things, I might actually set up a ram disk
11:31 AM Jymmm: Heh, need that much just to run Firefox with all it's memory leaks =)
11:31 AM phipli: Jymmm, true that
11:31 AM * phipli checks current Firefox status on this machine...
11:32 AM Wolf__: ziper: https://image.shutterstock.com/z/stock-vector-working-mechanism-of-dial-indicators-metrology-187924268.jpg
11:32 AM phipli: I'm only using 3.4gb total atm
11:32 AM phipli: Firefox is behaving and only using 721MiB
11:32 AM Jymmm: Used: 12.8GB
11:33 AM phipli: Memory hog HexChat is using 13.6MiB
11:33 AM Jymmm: FF 2.3GB atm
11:33 AM gregcnc: some indicators have a knob that is threaded into the shaft, often a oring or something beneath it. other have a cap over the end
11:34 AM phipli: heh. A friend at work plays with 6502 based 80s computers at home lots
11:34 AM Tom_L: is chrome any better?
11:34 AM Jymmm: Tom_L: For memory, yes.
11:34 AM phipli: I was reading some code he'd written at work and he was declaring most of his (appropriate) variables as bytes, not integers
11:35 AM Jymmm: Tom_L: But I have craploads of FF plugins to control/filter websites installed in FF
11:35 AM phipli: I pointed out he had 8GB of ram
11:35 AM phipli: chrome isn't great with ram either really
11:35 AM phipli: they use as much as they can
11:36 AM Jymmm: phipli: Ah, I only use it on my phone and hate it
11:36 AM phipli: I've drifted to FF simply because they're a little less...
11:36 AM phipli: interested in watching what you're doing and selling it
11:40 AM Kevin`: wasting ram once is fine. what happens is those data structures get put into arrays or sent over networks etc and person still doesn't know how to handle data efficiently
11:41 AM enleth: it's much more complex than even that
11:41 AM enleth: structure sizes have an enormous impact on CPU cache performance
11:42 AM IchGucksLive: can somone spess rouphing is correct
11:42 AM enleth: RAM may be fast compared to disk or network, but RAM access is still extremely slow compared to the CPU execution speed
11:42 AM IchGucksLive: spell ofcause
11:43 AM enleth: optimizin variable sizes can speed up a program by orders of magnitude if it helps the CPU maintain the working dataset in a single cache line
11:43 AM ziper: Wolf__, gregcnc I guess it is just a travel limiter
11:43 AM ziper: my gauge doesnt retract, I oiled it and it got better but its still not working right
11:43 AM gregcnc: probably needs cleaning
11:43 AM roycroft: great
11:44 AM roycroft: i just found a manual for my vfd that actually discusses the various settings
11:44 AM roycroft: i've been working with one that only list them and their value ranges
11:44 AM roycroft: i might not have had to ask so many questions about settign it if i had had this manual earlier
11:44 AM gregcnc: I have one that's slow, one day i'll clean and adjust it
11:45 AM IchGucksLive: Ah is there a Kinietics for a 6dof or all using puma
11:46 AM IchGucksLive: puma got j0-6
11:46 AM IchGucksLive: puma got j0-5
11:46 AM enleth: phipli: your friend might be right for the wrong reasons with those variables - his programs could be running faster without that having anything to do with overall memory usage
11:47 AM phipli: enleth, the programs were tiny tools that ran in sub second times anyway :)
11:47 AM enleth: phipli: oh well. I guess he just didn't want to get out of shape then.
11:47 AM phipli: heh
11:47 AM phipli: true
11:48 AM enleth: still, for any complex software, people who clam that computers have a lot of memory so structure sizes don't matter much usually have no idea whatsoever about CPU cache internals
11:49 AM phipli: I think most people probably don't have any idea about cache internals
11:49 AM enleth: it's probably *the* most complex aspect of software development, maybe second to real multi-CPU concurrency
11:50 AM enleth: wait, no. both of those are second and third to cache internals WITH multi-CPU concurrency
11:50 AM phipli: OpenCL stuff gives me a headache
11:50 AM phipli: turning a highlevel task into something that fits into those little blobs of program...
11:50 AM phipli: hurts
11:51 AM enleth: but it's not hard, it's *weird*
11:51 AM enleth: like functional programming
11:52 AM phipli: it feels like concurrent assembly with an overcomplicated set of instructions
11:52 AM gloops: you oiled the gauge ziper...
11:54 AM gloops: well, not much time today but i think that was the killer blow, im looking at mechnical completion tommorrow, aside maybe from a couple of nuts i cant buy local
11:55 AM ziper: gloops, yeah? is that bad? this one was only a dollar so I dont feel bad
11:56 AM gloops: this is a precision instrument ziper, the surface tension of oil can completely throw off any hope accuracy
11:56 AM gloops: of accuracy
11:58 AM ziper: there wasn't much hope of accuracy when the instrument wouldnt even retract itself
11:59 AM ziper: but why would a very light oil on the gears throw off accuracy?
12:00 PM Jymmm: ziper: crud sticks to oil
12:00 PM Jymmm: ziper: (but I get it =)
12:01 PM fragalot: hi
12:03 PM gloops: stuff like that usually runs dry, or with a tiny amount of oil, you can get stuff like watch cleaner in aerosol cans to try cleaning with, its probably gummy oil or grease and the particles stuck to it thats making it stick
12:05 PM enleth: which do you think is better, using bearing and spindle oil as a way oil, or using way oil as bearing and spindle oil?
12:05 PM enleth: assuming identical viscosity
12:06 PM fragalot: CAN they have identical viscosity?
12:06 PM gloops: spindle oil for spindle id say
12:06 PM fragalot: the whole idea behind way oil is that it's super thick so it doesn't get pushed away
12:06 PM fragalot: and the idea behind spindle oil is that it's runny to lubricate at high speed
12:07 PM gloops: yes, but using thin oil on the ways regularly is better than using the wrong oil in the spindle
12:07 PM gloops: imo
12:07 PM fragalot: agreed.
12:08 PM enleth: tl;dr I have a jug of generic ISO 68 machine oil that is "designed for lubrication lightly or moderately loaded machine elements and
12:08 PM enleth: industrial equipment, roller and plain bearings, guides, spindles and open-mechanical transmissions"
12:09 PM enleth: wondering if I should get a jug of ISO 68 way oil too
12:09 PM fragalot: Meh.
12:09 PM gloops: sht what do they call that oil additive for worn engines
12:09 PM fragalot: the only real "advantage" of proper way oil is that it's not prone to stick-slip
12:10 PM gloops: slick 50 - you can get that from most car shops, good sticky stuff
12:10 PM enleth: fragalot: and yes, they do have almost identical kinematic viscosity according to the datasheets
12:11 PM fragalot: enleth: Weird :-)
12:11 PM enleth: fragalot: 69.0mm^2/s and 68.5
12:11 PM enleth: which is, I think, what makes them ISO 68 oils?
12:11 PM fragalot: it is
12:11 PM * fragalot learned something today
12:11 PM fragalot: in any case - try the oil, if you find that you have stick-slip issues, then get the way oil too
12:12 PM enleth: I'm not too keen on cleaning the machine if it turns out to be a problem
12:12 PM enleth: eh, I guess I'll order the way oil too, it's cheap
12:13 PM enleth: at least I'll have more regular machine oil for other uses
12:13 PM enleth: if I had two pumps, I could get fancy and pump way oil for the ways, machine oil for the ballscrews
12:14 PM Tom_L: send me some of it
12:14 PM enleth: but I only have one and those ballscrews are supposed to be fine with way oil
12:14 PM Tom_L: what are you using for way oil?
12:14 PM fragalot: so today i've spent the afternoon building a plywood mock-up of my mill
12:14 PM fragalot: what. a. horrible. material.
12:14 PM fragalot: it's so spongey
12:15 PM gloops: https://www.ebay.co.uk/itm/Slick-50-Engine-Treatment-Oil-Additive-Petrol-Diesel-Extends-Engine-Life-750ml/141986024203?
12:15 PM fragalot: gloops: way oil is cheaper
12:15 PM gloops: are you using plywood for the mold?
12:15 PM fragalot: gloops: "mock-up", not mold
12:16 PM enleth: Tom_L: a local refinery makes ISO 68 way oil that's even marketed as a replacement for Mobil Vactra 2, the recommended way oil for Bridgeports
12:16 PM gloops: fragalot yeah probably, its good stuff though, sticks, really sticks to anything that slides
12:16 PM fragalot: but eventually, yes, the mold will be made of plywood & heavily coated with polyurethane
12:16 PM gloops: lol
12:16 PM Tom_L: vactra 2 is way oil?
12:16 PM fragalot: gloops: I don't like things to stick too much
12:16 PM Tom_L: i've never really had to pay attention to that
12:16 PM gloops: just line it with cling film
12:17 PM fragalot: I like being able to wipe my lathe clean rather than having to get a spatula to scrape the dusty mess off
12:17 PM Wolf__: the engine additives can mess things up because too slick
12:17 PM Wolf__: lets you crank down too much on the gibs
12:17 PM enleth: $50 shipped for a 20l/5.3gallon jug
12:17 PM fragalot: gloops: I'm not sure if that's a good idea; I imagine the clingfilm sticking to the granite afterwards?
12:18 PM gloops: well if you want a good finish youre gonna be polishing that plug for weeks
12:18 PM fragalot: not bothered about a good finish, but I HATE bits of plastic sticking out still
12:18 PM roycroft: grease it up
12:18 PM fragalot: I already have that on the shed's concrete slab
12:19 PM fragalot: roycroft: Aye. PU & a good release agent should work fie
12:19 PM fragalot: fine
12:19 PM enleth: Tom_L: yes, and it's been the official BP way oil pretty much forever
12:20 PM enleth: OK, there is one important reason for me to get the proper stuff - it sticks to vertical ways, preventing rust to the upper part of column ways
12:20 PM gloops: well shouldnt be a problem if the mold is sectional, like so you can unscrew it and part piece at a time
12:20 PM Tom_L: i knew that i just never kept track of the different types of oil my bud used and what they were for
12:21 PM Tom_L: i'll probably try to get a little from him
12:23 PM Tom_L: i wonder if regular coolant would work for a mister
12:23 PM enleth: anyways, I'm ready to order parts for the new lube system
12:24 PM enleth: it should be there mid-week, so I'll be taking the mill apart once again to clean all the ways properly and unclog all oiling orifices
12:24 PM enleth: and I hope it's the last time in the next 10 years that I need to do it
12:24 PM Tom_L: http://itwprofessionalbrands.com/1334/accu-lube/semi-synthetic-metalworking-fluids/rustlick-ultracut-380r
12:25 PM Tom_L: he uses that for coolant
12:25 PM enleth: Tom_L: ah, the "proper" way oils are also supposed to not interfere too much with coolant systems
12:25 PM Tom_L: yeah
12:25 PM enleth: they end up in the coolant tank eventually
12:26 PM fragalot: gloops: thisi s EPOXY granite we're talking about. sectional or not; without a good release agent, it is NOT coming off until I chuck it in a fire :P
12:26 PM Tom_L: not if you don't have one :)
12:26 PM enleth: and they should float well above the pump inlet
12:26 PM gloops: fragalot at least you wont have to worry too much about draft
12:26 PM Tom_L: i'm gonna try to get by with mist coolant and see how it goes
12:26 PM fragalot: gloops: yup
12:28 PM Tom_L: i actually think he ran a skimmer for a while
12:29 PM fragalot: Tom_L: but those remove the benifitial bacteria!
12:43 PM JT-Shop: Tom_L: I just mill dry on the BP everything I've tried like mist is just a mess
12:43 PM Tom_L: no lube at all?
12:44 PM Tom_L: maybe i'll leave the oil off and just use the air
12:44 PM fragalot: TiCN coated carbide actually lasts longer dry
12:44 PM Tom_L: https://www.ebay.com/itm/Mist-Coolant-Lubrication-Spray-System-For-8mm-Air-Pipe-CNC-Lathe-Mill-DrillATBD/202151085390?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D8a5429cbea7048ef9ee9adf8cf71f044%26pid%3D100675%26rk%3D3%26rkt%3D15%26sd%3D273036235047%26itm%3D202151085390&_trksid=p2481888.c100675.m4236&_trkparms=pageci%253Af76f7cc4-0391-11e8-aa33-74dbd18067f3%257Cparentrq%253A38ee7cbb1610abc1f85bbecaffe3ed76%257Ci
12:44 PM Tom_L: gonna try one of those and see what happens
12:44 PM fragalot: good god that cheap!
12:45 PM Tom_L: i've got a Ti coated cutter i like pretty well
12:45 PM Tom_L: yeah
12:45 PM * fragalot orders 4
12:45 PM JT-Shop: dang that is cheap
12:45 PM Tom_L: can't hardly miss on those
12:45 PM Tom_L: mm hose fitting but that can be fixed
12:45 PM fragalot: new fitting will cost more than this thing
12:46 PM Tom_L: haha
12:46 PM Tom_L: mine was a bit more due to US stock
12:46 PM fragalot: Right, I just ordered 2 of those
12:46 PM fragalot: let's find out if they work.
12:46 PM Tom_L: i've got more of that snake pipe if i need it too
12:47 PM Tom_L: may even have a Y adapter
12:47 PM Tom_L: if it's the same size
12:48 PM Tom_L: if you get chinaco just get it before their new year starts
12:51 PM fragalot: either they take forever to get it here, or customs will delay it
12:51 PM fragalot: either way i'm not expecting next-day delivery
12:51 PM fragalot: :P
12:54 PM Roguish_shop: those mist things are on Amazon also.
12:54 PM JT-Shop: damn plasma torch is messing up, Red Fault LED is lights up sometimes at arc start... Manual says "When illuminated, indicates that a fault condition exists, which prevents system operation."
12:54 PM JT-Shop: very informative lol
12:54 PM fragalot: haha
12:55 PM fragalot: most common issue is a lack of air pressure when starting
12:55 PM fragalot: I added a small buffer to mine which seems to help a lot
12:55 PM JT-Shop: that's a different LED
12:56 PM fragalot: well then i guess you'll just need to get a new machine
12:58 PM JT-Shop: well Hypertherm has a good troubleshooting page for fail to start an arc reading that now
12:58 PM fragalot: on a more serious note - is your swirler still OK?
12:58 PM JT-Shop: I might need to replace the consumables I'll check them
12:59 PM fragalot: I assumed that was step #1, before reading the manual xD
01:02 PM JT-Shop: https://www.hypertherm.com/en-US/learn/articles/pac-systems---starting-problems
01:04 PM pink_vampire: i hate my life, in a funny way
01:05 PM Jymmm: pink_vampire: I'd suggest NOT going to Evil Clown College then ;)
01:05 PM pink_vampire: i took a picture
01:06 PM fragalot: as you do.
01:06 PM Wolf__: o.0
01:06 PM gloops: of your life?
01:06 PM pink_vampire: https://i.imgur.com/8nF1S3G.jpg
01:06 PM Jymmm: gloops: Yeah, it's up on youtube
01:07 PM gloops: a student did one of those, it was her unmade bed, takeaway trays, empty drinks bottles general crap all over
01:07 PM gloops: sold for a fortune i think
01:07 PM pink_vampire: i was soo happy to ad those 2 regulators, and then i saw it..
01:07 PM Wolf__: ->
01:07 PM fragalot: pink_vampire: the little arrow?
01:08 PM gloops: this looks sophisticated
01:08 PM fragalot: or are they marked "in" and "out" rather than an arrow? :P
01:09 PM pink_vampire: i wish i could connect one of them backwards
01:10 PM pink_vampire: it's look so beautiful and annoying at the same time
01:11 PM Wolf__: I would just turn the one on the left more so the knob is up and gauge is forward
01:11 PM Jymmm: pink_vampire: You could, just install a male fitting
01:12 PM pink_vampire: i need the hoses to go to the left
01:13 PM Wolf__: I use 1/4 and 3/8 DOT air lines and push connect fittings to do my equipment runs
01:14 PM IchGucksLive: gn8
01:14 PM fragalot: everyone is a critic :P
01:15 PM Wolf__: not really critical, just costs less and easier to setup https://i.imgur.com/OeR3fzr.jpg
01:16 PM Wolf__: and for my noga mister https://i.imgur.com/fkxm4Dq.jpg
01:16 PM pink_vampire: Wolf__: very nice setup
01:17 PM jesseg: what is that? that thing on top with two (air? water?) lines going to it?
01:17 PM fragalot: looks like a cylinder
01:17 PM Wolf__: 4” dia air cylinder, 1” stroke
01:18 PM jesseg: Does it release the collet or something?
01:18 PM Wolf__: yup
01:18 PM fragalot: with a wireless solenoid on it, apparently
01:19 PM jesseg: How does it release? Just press really hard, which means there must be a counter spring in the spindle which is what actually holds the collet tight?
01:19 PM Wolf__: lol yup fragalot
01:19 PM jesseg: I've thought about mounting an air wrench at the top of my mill so when the quill comes all the way up it goes into the socket on the air wrench
01:20 PM Wolf__: jesseg: exactly, bellville washers
01:20 PM jesseg: Wolf__, very very clever!
01:20 PM fragalot: jesseg: wouldn't it be better to move the air wrench down, rather than rely on your quill never going al lthe way up again?
01:20 PM fragalot: jesseg: I think john saunders from NYCCNC makes kits for that
01:20 PM Wolf__: not original idea lol
01:21 PM jesseg: fragalot, oh no it's the oldest idea in the book
01:21 PM Wolf__: hoss and tormach both use air cylinders
01:21 PM jesseg: oh, the air wrench is old idea
01:21 PM jesseg: I don't know about the way Wolf__ did it, but it sure is cool
01:21 PM fragalot: it is -but I never heard of relying on the quill travel for it
01:22 PM fragalot: knowing myself, I'd release it all the way up whilst it's running
01:22 PM fragalot: in reverse.
01:22 PM jesseg: fragalot, LOL
01:22 PM jesseg: yeah just have an electric or air brake on the drawbar head.. Set spindle direction then apply the break as needed
01:23 PM Wolf__: most air wrench systems are either air cylinder driven or spring driven down when you go to run the draw bar ou
01:23 PM Wolf__: t
01:25 PM fragalot: i'm not a fan of having the spindle accidentally run at a bazillion rpm & have the BT30 face mill go flying, lol
01:26 PM Wolf__: ^ no way I would use the quill travel to engage the wrench
01:29 PM * fragalot sneaks up to Wolf__'s mill and pushes the little red button on the solenoid valve when he's not looking
01:30 PM Wolf__: wouldnt do much, its in pieces lol
01:30 PM fragalot: I'mma press it anyway
01:31 PM pink_vampire: https://i.imgur.com/vT201EB.jpg
01:31 PM pink_vampire: much better
01:31 PM Wolf__: https://i.imgur.com/uetkDdd.jpg I have a little bigger one for my new mill
01:31 PM pink_vampire: less parts
01:31 PM Loetmichel: fragalot: all of the air-driven drawbar heads i have seen so far apply a pretty large surface the moment the cylinder goes down, i doubt a normal spindle motor can hold up ANY RPM against that.
01:31 PM fragalot: pink_vampire: That looks like a win to me.
01:32 PM pink_vampire: also a win for me
01:32 PM Wolf__: looks good pink
01:32 PM pink_vampire: now to the hard part
01:32 PM fragalot: Loetmichel: of course they can, your spindle keeps going whilst the nut either undoes itself, or permanently bonds with the toolholder.
01:32 PM pink_vampire: MIP is the same as NPT?
01:33 PM fragalot: Loetmichel: or do you mean they apply a brake,
01:33 PM fragalot: Loetmichel: also -- what jesseg suggested was a stationary head & use the spindle to turn the nut
01:33 PM fragalot: so there.
01:33 PM fragalot: :P
01:34 PM Loetmichel: Usually those systems are made intentionally in a way that the mating surfaces on air ram and spindle shaft are so large that the WORK as a brake
01:34 PM fragalot: pink_vampire: MIP = Male NPT
01:34 PM Loetmichel: ah, misunderstood then
01:34 PM pink_vampire: <3
01:34 PM Loetmichel: i thought of air operated drawbars on top of the spindle
01:34 PM fragalot: pink_vampire: http://pipeandhose.com/taxonomy/term/29
01:34 PM Loetmichel: (hollow spindle that is)
01:35 PM pink_vampire: cool!
01:35 PM pink_vampire: how much pressure a jar can take?
01:35 PM gregcnc: jar?
01:35 PM pink_vampire: yes
01:36 PM gregcnc: glass?
01:36 PM pink_vampire: a glass jar
01:36 PM gregcnc: fuck that
01:36 PM fragalot: none.
01:36 PM fragalot: typical glass jars are at best designed to hold a light vacuum
01:37 PM gregcnc: let us know when you get back from the hospital
01:38 PM MrHindsight: fragalot: vacuums are pretty light :)
01:38 PM fragalot: ba dum tisch
01:39 PM MrHindsight: it's the heavy vacuums you have to watch out for
01:39 PM gloops: champagne bottle takes a bit more
01:39 PM pink_vampire: what is the pressure for mist?
01:39 PM gloops: if you dont want the champagne ill have it
01:39 PM Wolf__: I run 20-30psi
01:40 PM Wolf__: https://i.imgur.com/9HOn0vS.jpg water filter housing for the tank
01:40 PM pink_vampire: I think champagne is a very good coolant.
01:40 PM MrHindsight: https://www.youtube.com/watch?v=OuHBzK-LK24 30 Marshmallows In A Huge Vacuum Chamber
01:40 PM pink_vampire: where did you got it?
01:41 PM Wolf__: amazon
01:41 PM gloops: fire extinguisher will hold it
01:41 PM pink_vampire: gloops: it is not transparent
01:41 PM gregcnc: yeah i've seen the water filter setup online
01:41 PM fragalot: Wolf__: Neat thinking of just using an empty filter housing
01:42 PM Wolf__: 10” slim water filter housing, 1/4 npt fittings, drilled and tapped the top for the pickup line
01:42 PM gloops: why does it need to be transparent?
01:42 PM Wolf__: https://i.imgur.com/au8jYKa.jpg
01:42 PM fragalot: CHINA
01:43 PM Wolf__: yeah…
01:43 PM Wolf__: full setup https://i.imgur.com/6h18AtY.jpg + regulator and solenoid valve
01:44 PM pink_vampire: very nice setup!
01:44 PM gloops: my mrs cakes do that in an ordinary oven
01:45 PM gloops: dont forget chinese new year looming, if ordering anything - expect delays
01:45 PM pink_vampire: https://i.imgur.com/D9x7CC6.jpg
01:45 PM pink_vampire: Centrum multivitamin mist jar
01:46 PM Wolf__: lol
01:46 PM gregcnc: I have an acculube mister i have to replumb. all the oil lines crumbled. it's gravity fed.
01:47 PM Loetmichel: pink_vampire isnt centrum the company that make those superflouse "mineral supplements"?
01:47 PM Loetmichel: superflous
01:50 PM pink_vampire: I have an idea for beauty mini mist jar
01:51 PM pink_vampire: https://i.imgur.com/zh720Tn.jpg
01:51 PM gregcnc: clay may not be effective coolant
01:52 PM pink_vampire: it is empty
01:52 PM gregcnc: no coolant will not be effective for sure
01:52 PM pink_vampire: LOL
01:54 PM pink_vampire: so Centrum VS Loreal
01:55 PM gregcnc: i wonder what's going on here
01:55 PM gregcnc: https://www.ebay.com/itm/253390810314
01:56 PM Loetmichel: btw: anyone have a good idea what to use as a "homebrew" mist coolant for aluminium? Preferably evaporating without leaving stains or oxide.
01:56 PM gregcnc: ethanol
01:56 PM pink_vampire: 767 is over price for that
01:56 PM pink_vampire: new is about 650,
01:57 PM pink_vampire: and here the motor is not original
01:57 PM Loetmichel: 50/50water and IPA with a dab of dish detergent leaves "oxide scars" in the AlMg3
01:57 PM pink_vampire: and also it is the old NSK design.
01:57 PM fragalot: pink_vampire: why not just get a filter housing? or, well.. anyting else that is actually designed to take some pressure?
01:58 PM pink_vampire: take some.. 30 psi...
01:58 PM Loetmichel: fragalot: that makeup glass will hold quite a bit of pressure...
01:58 PM fragalot: Loetmichel: but the lid may not
01:58 PM Loetmichel: it does
01:58 PM fragalot: Well then.
01:58 PM Loetmichel: i know that kind of makup. the lids are made of some "bakelite" like plastic
01:58 PM Loetmichel: hard as nails
01:59 PM Wolf__: http://a.co/i8dF5oe'
01:59 PM Loetmichel: i guess its good for 150 PSI at least, if not more
01:59 PM Wolf__: cheap enough, my time is worth more imo
02:00 PM pink_vampire: the clay mask smell better
02:02 PM Wolf__: plus the filter housing is rated to 125psi so no worries about it exploding if you have a regulator issue
02:03 PM pink_vampire: i think the multivitamin can increase the rigidity of the machine over time.
02:04 PM gregcnc: loetmichel a light paraffin oil like lamp oil? takes some time to dry, but it will
02:05 PM pink_vampire: but seriously, I think those water filter just too big for what i need.
02:05 PM fragalot: pink_vampire: they exist in all sizes
02:05 PM fragalot: hang on i'll find a tiny one we use a lot at work
02:06 PM fragalot: pink_vampire: metric or imperial?
02:06 PM gregcnc: festo and others make air line lubricators?
02:06 PM Loetmichel: gregcnc: could work, i still have some citronella lamp oil here... could check how good that is.
02:06 PM Loetmichel: thanks
02:07 PM gregcnc: I use it all the time
02:07 PM pink_vampire: fragalot: i'm working with 1/4" npt
02:07 PM fragalot: pink_vampire: https://agrimart.net/1-2-poly-line-strainer/
02:08 PM fragalot: there are transparent versiosn
02:08 PM fragalot: versions*
02:08 PM Wolf__: http://a.co/6UZnYDb
02:08 PM fragalot: https://www.kleen-ritecorp.com/p-137-spraying-systems-strainer-12f-50-mesh.aspx
02:08 PM fragalot: (they are a little smaller than your fist)
02:09 PM fragalot: but Wolf__'s suggest is probably more of a sensible size
02:12 PM pink_vampire: fragalot: look like a very nice idea!
02:12 PM pink_vampire: Wolf__: super!
02:21 PM Loetmichel: Deejay: do you know the name of that mist cooling device that akku has?
02:21 PM Loetmichel: i cant remember its name
02:22 PM Deejay: nope
02:23 PM gregcnc: special kind of mister?
02:30 PM Loetmichel: gregcnc: little aluminium block with a suction hose for the fluid, an air hose with a needle valve and a short nozzle to mix the two
02:30 PM Loetmichel: and IIRC a magnet to mount it on the spindle
02:31 PM Wolf__: so, a noga super cool
02:31 PM Wolf__: oh wait, I know the one
02:32 PM gregcnc: kool mist?
02:33 PM gregcnc: fogbuster?
02:33 PM Wolf__: fog buster sounds like it
02:36 PM gloops: why not just use an airbrush? theyre cheap as
02:37 PM fragalot: not enough air pressure
02:37 PM fragalot: with an airbrush, your goal is to atomize the fluid
02:37 PM fragalot: with a mist cooling device, your goal is to blow the chips away
02:38 PM Wolf__: the plus with the fog buster or modified noga mini-cool is air blast + coolant droplets
02:39 PM Loetmichel: yeah, fog buster it was
02:39 PM Loetmichel: thanks
02:39 PM Wolf__: my filter housing + noga mini-cool works the same way
02:42 PM Loetmichel: gloops: what wolf said
02:43 PM Loetmichel: the fogbuster doesent "mist" in the closest meaning of the word
02:43 PM Loetmichel: it spews out high speed droplets of coolant
02:43 PM gloops: https://www.youtube.com/watch?v=CNLuPgr7NdY
02:43 PM gloops: diy fogbuster
02:43 PM gloops: thats pretty obvious really, the design
02:43 PM Loetmichel: so you dont breathe in loads of gassified coolant
02:44 PM gloops: a plastic pen top!
02:44 PM fragalot: Loetmichel: you still do though; it's inevitable.
02:44 PM Wolf__: mine is a copy of oxtools and james kilroys build
02:45 PM Loetmichel: fragalot: a lot less than with a conventional atomizer though
02:45 PM fragalot: sure
02:46 PM gloops: i dont need coolant as mainly working wood, but i am hoping to do some ally, this is better than flooding on a machine with a wooden surface
02:47 PM fragalot: if all you do is "some alu", air hose or vacuum + WD40 works well enough
02:47 PM Loetmichel: fragalot: WD40 is great as a coolant
02:48 PM fragalot: Loetmichel: it is, only downside is that it's expensive 'round here
02:48 PM Loetmichel: but way to expensive over here to do it 8 hours a day 5 days a week
02:48 PM fragalot: you can't get the gallon jugs here, only the spray cans
02:48 PM Loetmichel: exaclty
02:48 PM gloops: yeah, i dont want to be stood watching it though
02:48 PM fragalot: hence "some alu" :)
02:48 PM Loetmichel: l<->t
02:49 PM Loetmichel: as i said: i now use a mix of 50% Isopropyl alcohol and water (and a dab of dish soap to get it to foam)
02:49 PM gloops: ill be online banking all the cheques while this is happening
02:50 PM Loetmichel: wors fine as a coolant with alu, but has some issues with dulling the surfaces and leaving "water marks" on the alu
02:50 PM fragalot: I've tried alcohol before and whilst it worked alright, I didn't quite like how flammable that stuff si
02:50 PM fragalot: never thought to water it down
02:50 PM fragalot: Loetmichel: even if you use demi-water?
02:50 PM Loetmichel: yes
02:50 PM Loetmichel: its no chalk
02:50 PM Loetmichel: something is oxidizing the aluminium
02:50 PM fragalot: Hm.
02:51 PM Loetmichel: white marks on the alu, and when you grind them off with fine emery cloth you get pitting
02:52 PM gloops: for small jobs youre better off making a tray and sit the job in a bath
02:52 PM fragalot: gloops: that sounds like a recipe for re-cutting chips
02:52 PM fragalot: or do you mean after they're machined?
02:53 PM fragalot: if so, that just sounds messy
02:53 PM gloops: whilst machining
02:53 PM fragalot: I disagree then. :-)
02:53 PM gregcnc: ask the boss for a Datron
02:53 PM gloops: its how glass is done, glass a different matter though i suppose
02:54 PM fragalot: gloops: that's for a different reason
02:54 PM fragalot: glass is submerged because that makes it MUCH less likely to crack
02:54 PM gloops: ill rig something up from old bike parts when the time comes
02:54 PM Loetmichel: gloops: tray and bath doesent work that well with a vacuum table ;)
02:54 PM fragalot: you can literally cut a thin pane of glass with scissors when under water
02:55 PM gloops: plus the dust
02:58 PM Loetmichel: gloops: you dont want to have loads of water around that machine...
02:58 PM gloops: stone cutting is the thing to be in, theres some money there
02:58 PM Loetmichel: especially not with the vacuum table active: http://www.cyrom.org/palbum/main.php?g2_itemId=16179&g2_imageViewsIndex=1
02:59 PM fragalot: Loetmichel: but the vacuum table will work BETTER
02:59 PM gloops: is the psu? lol
02:59 PM fragalot: Loetmichel: it's eaiser to generate a vacuum when the medium is incompressible like water
02:59 PM fragalot: :P
03:00 PM Loetmichel: gloops: ??? what PSU?
03:00 PM gloops: looked like a power supply with polythene over it
03:00 PM Loetmichel: fragalot: i doubt the shopvac would laugh about loads of water though
03:01 PM Loetmichel: my pic?
03:01 PM gloops: https://www.youtube.com/watch?v=UxPUjz2kwg4 < see, not messy in a tray
03:01 PM fragalot: Loetmichel: wet'n'dry vacuum. wet'n'dry.
03:01 PM gloops: yes Loet
03:01 PM Loetmichel: its the back of a tempest switch enclosure
03:01 PM fragalot: Loetmichel: either that, or a nice water pump & replace the impeller every few hours or runtime as it's cavitated to shit
03:01 PM Loetmichel: the green tape is just to close the unused holes of the vacuum table
03:02 PM fragalot: that said, actually
03:02 PM fragalot: if you, theorethically, had a water based vacuum system
03:02 PM Loetmichel: fragalot: it IS a wet and dry one... but only with a 5 liter bucket
03:02 PM fragalot: could you simply do this with a piston pulling out some volume?
03:03 PM fragalot: since the whole system is filled with water, there is no "gas" to take up the volume, but the water may change states to compensate I guess
03:03 PM Loetmichel: fragalot: depends on how tight your seal is i suppose
03:03 PM fragalot: Loetmichel: 2 pistons & check valves :P
03:03 PM Loetmichel: ... as i tend to mill thru the workpice: not an option.
03:03 PM fragalot: larger pistons
03:03 PM Loetmichel: there is a reason why i use a shopvac and no vacuum pump
03:03 PM fragalot: >.>
03:03 PM Loetmichel: i need volume
03:04 PM Loetmichel: gloops: the reason its diagonally on there is because the machine was a bit small
03:04 PM fragalot: vacuum pumps generally take forever too
03:05 PM Loetmichel: gloops: thats the whole 19" enclosure in all its glory: http://www.cyrom.org/palbum/main.php?g2_itemId=16414&g2_imageViewsIndex=1
03:05 PM gloops: is that the one you made?
03:06 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16426&g2_imageViewsIndex=1 <- and put together
03:06 PM Loetmichel: yes
03:06 PM fragalot: pretty robust looking, lol
03:06 PM Loetmichel: Slightly different one the last pic
03:06 PM fragalot: could have done with a few more screws imho
03:06 PM gloops: looks ok yeah
03:11 PM gloops: i will soon be cutting aluminium like a hot knife through butter
03:24 PM Loetmichel: fragalot: i make military shielded IT tech. the overabundance of screws let me omit any EMI gaskets. its simply cheaper that way
03:24 PM Loetmichel: if the screws are less than 1.5" from each other
03:24 PM fragalot: I was wondering if that was the reason :-)
03:29 PM miss0r: Motorbrush holder with water injection - part complete :D yay !
03:29 PM fragalot: :o
03:30 PM miss0r: I'm glad I waited for the brushes to arrive before I made the part, lol. They were advertised as 6mm diameter(round brushes) but the ones i got was 6.25-6.28
03:31 PM miss0r: You gotta love generic chinesium combined with western sales wank :D
03:31 PM fragalot: so you got MORE than what you paid for, and you're still complaining
03:31 PM miss0r: Some people are just never happy :D
03:31 PM fragalot: (also, it sounds like they sell 1/4" and 6mm from the same lots :P)
03:34 PM Loetmichel: fragalot: its both in the same ballpark. good enough for sales people ;)
03:35 PM fragalot: Loetmichel: it's extra padding because the holders they sell are even wider
03:36 PM miss0r: fragalot This is what it looks like: https://imgur.com/a/eN5ON
03:36 PM fragalot: looking good!
03:37 PM miss0r: sadly I didn't take a picture before installing the two axle seals & the bearing
03:37 PM miss0r: It looks nice inside where I opened up into the water injection hole with a t-slot cutter
03:37 PM Loetmichel: fragalot: :-)
03:41 PM malcom2073: Is it possible to have a user defined M command take a parameter that does *not* start with a P or Q?
03:42 PM fragalot: I think you only get the 2 arguments
03:43 PM malcom2073: And they must start with P and Q?
03:43 PM fragalot: Yes
03:43 PM malcom2073: Doh, alright
03:52 PM miss0r: Next week i'm gonna go tell the boss to allow me to have three day weeks or quit my job. I'm Going to do this stuff two days a week now / full time. I don't have enough time any more to take care of customers :]
03:52 PM fragalot: xD
03:52 PM miss0r: Pretty big stuff, considering I've been working for the same electric company for 10 years plus some
03:53 PM miss0r: But I'm spending waaay too much of the night going out to repair machines now. I should be doing that in the day time as my primary job
03:53 PM miss0r: (I like it alot more than being an electrician anyway)
03:54 PM fragalot: understandable
03:54 PM miss0r: The misses and I just did the math tonight. We can do it ;D (I'm pretty psyched here)
03:56 PM fragalot: if you don't love what you're doing, it's not worth doing
03:56 PM fragalot: I changed jobs last month
03:56 PM Tom_L: mister arrived today
03:56 PM fragalot: no regrets at all.
03:57 PM jesseg: well the liquid in my warm flask is bubling slowly.
03:57 PM jesseg: When a bubble forms in a vacuum it really gets big fast.
03:57 PM fragalot: lol yeah
03:57 PM gloops: the liquid in my glass is disappearing quickly
03:57 PM fragalot: especially fun when de-gassing epoxies
03:58 PM fragalot: "no no no stay down no no nooooooo"
04:00 PM jesseg: lol
04:00 PM Deejay: gn8
04:05 PM gloops: i notice people are using granite composites for plates as well as the machine block
04:05 PM fragalot: if you can machine it, why not?
04:06 PM Tom_L: more stability?
04:06 PM gloops: well i have some random pieces that have been machined, it was too heavy for my z
04:06 PM fragalot: counterweight the Z
04:06 PM fragalot: best way i've seen is using an air cylinder
04:07 PM gloops: machined - for work surfaces and fireplaces that kind of stuff, wonder how good that machining is, i never really checked it
04:07 PM Tom_L: i don't think i'll need a counterweight on mine
04:07 PM fragalot: machined for fireplaces == it looks flat
04:07 PM fragalot: -ish
04:07 PM gloops: yeah, you put a ruler on it it looks pretty flat
04:07 PM fragalot: same for work surfaces; they do not guarantee any form of tolerance
04:08 PM gloops: good enough for wood, i dont know about metal work
04:08 PM fragalot: gloops: is it shiny enough to do a reflection test?
04:08 PM Tom_L: i can't decide if i want to go with a 1" grid pattern on my X like i did on the sherline or use a coarser pattern
04:08 PM gloops: hmm, probably would be with a bit of a polish
04:09 PM fragalot: gloops: see if you can reflect a flat surface with a paper grid on it, see if the squares or lines still look straight
04:09 PM gloops: you can get granite cutting boards
04:09 PM fragalot: that same test is great for perpendicularity too
04:10 PM gloops: i might look at that for my next contraption
04:11 PM Tom_L: got my spindle mounted today and somewhat aligned
04:11 PM Tom_L: gonna work on it a bit more this evening i think
04:11 PM gloops: any day now Tom by the sounds of it
04:12 PM Tom_L: i did a grid pattern in cad for it today
04:12 PM Tom_L: just unsure if i want 1" or something a bit wider
04:12 PM * roycroft is heading out to test his new spindle presently
04:12 PM gloops: the grid for testing it?
04:13 PM Tom_L: what's standard stud size for most of these small cncs?
04:13 PM Tom_L: no for the table hole pattern
04:13 PM gloops: oh right
04:13 PM fragalot: 6-8mm
04:13 PM Tom_L: 1/2"?
04:13 PM Tom_L: or smaller?
04:13 PM fragalot: (you did say "small")
04:13 PM fragalot: what size CNC & what materials?
04:13 PM Tom_L: looking at a 4" kurt vise
04:14 PM fragalot: at least 3/8 then
04:14 PM Tom_L: you haven't seen it?
04:14 PM fragalot: no
04:15 PM Tom_L: https://www.youtube.com/watch?v=EqHV0Or4Ad8
04:15 PM fragalot: looks nice!
04:16 PM gloops: machine base £10 https://www.ebay.co.uk/itm/Pink-marble-grate-slab/192431968362?
04:16 PM fragalot: my misters have just been shipped :P
04:16 PM fragalot: so they should be here some time end of feb
04:18 PM fragalot: gloops: if you want to spend the time flattening that, sure
04:19 PM fragalot: & then crack it by using concrete anchors :P
04:20 PM gloops: i reckon its pretty flat stuff, been cut on a big machine
04:21 PM fragalot: it's not kept to any tolerance worth mentioning though
04:21 PM Wolf__: Tom_L: guess you could look at the hole spacing and sizes https://saundersmachineworks.com/collections/all uses on their fixture plates
04:21 PM fragalot: all they care about is that the thickness is "roughly the same"
04:22 PM gloops: well builders dont need fine tolerances, but its been surfaced and polished on a big cnc machine, i bet its not far out
04:23 PM fragalot: but it will need flattening
04:23 PM fragalot: y'know what
04:23 PM fragalot: gloops: it's 10£
04:23 PM fragalot: take one for the ream
04:23 PM fragalot: team
04:24 PM gloops: what needs flattening?
04:24 PM fragalot: the slab's surface, it won't be machine grade
04:24 PM fragalot: visually flat, sure
04:24 PM gloops: how far out do you reckon it is?
04:25 PM fragalot: that's the point; you can't know.
04:25 PM fragalot: especially if it's been in a fireplace for god knows how long
04:26 PM gloops: yeah they not real fires - only flame effect
04:26 PM gloops: how are you getting yours flat?
04:26 PM fragalot: casting in cast iron bars
04:26 PM fragalot: then lots of cursing
04:26 PM gloops: that wont make it flat heh
04:27 PM fragalot: no, but the scraping will
04:27 PM gloops: hand scraping?
04:27 PM fragalot: yup
04:27 PM Tom_L: looks like they do 1.5" centers
04:28 PM Tom_L: err 1.25"
04:28 PM Wolf__: 440 plate is 1
04:28 PM Wolf__: "
04:28 PM Wolf__: mini pallet is 0.75”
04:28 PM Wolf__: sizes are all over the place lol
04:28 PM Tom_L: yeah
04:28 PM gloops: well i wouldnt like to be trying to cut epoxy/granite, you need to be abrading it
04:29 PM Tom_L: 3/8 studs would likely be plenty big enough for what i'd do
04:29 PM gloops: i mean cut it is an with a sharp tool
04:29 PM gloops: then you need an engineers plate that size
04:30 PM Wolf__: 3/8 studs are whats with the hold down set on my jet 840
04:30 PM Tom_L: do they have a 3/8" clamp kit too?
04:30 PM fragalot: gloops: hence the cast iron
04:31 PM gloops: oh i see, youre going to have cast iron rails set in the resin
04:31 PM fragalot: yes
04:31 PM Tom_L: looks like the top part of the holes are reamed and the threads are below that
04:39 PM gloops: http://www.theageofelegance.com/galleries/victorian/beveled/ae352-vb/ae352.htm#
04:40 PM gloops: pretty staggering to think that was made by hand, somebody went crazy making that
05:21 PM phipli: anyone use kicad?
05:24 PM jesseg: A friend of mine wants to
05:24 PM phipli: I'm giving it a try for the first time
05:24 PM jesseg: cool!
05:25 PM phipli: when I created a new component, it created two pieces of text on top of eachother
05:25 PM jesseg: I tried it years ago, but it wasn't ripe yet
05:25 PM phipli: I CAN NOT SELECT JUST ONE OF THEM
05:25 PM * phipli cries
05:25 PM phipli: video tutorial, the guy just does it. no comments made
05:25 PM JT-Shop: I hate when that happens
05:26 PM phipli: it opens a "clarify" menu so you can say which you want, but clearly has a bug on my setup where after selecting one, it doesn't select it
05:29 PM MarcelineVQ: don't you hold down the button for context menus like that?
05:29 PM MarcelineVQ: oh are you able to do that but it doens't actually work
05:29 PM phipli: how are you meant to move an object when two are stacked?
05:30 PM phipli: the clarify thing works for rotate...
05:30 PM phipli: but not move
05:30 PM phipli: right
05:30 PM phipli: got it
05:30 PM phipli: you press "m"
05:30 PM phipli: obviously
05:30 PM phipli: wysiwyg
05:30 PM phipli: just a shame the thing to see was a random, unspecified key on my keyboard
05:31 PM phipli: sorry folks :) as you were
05:32 PM phipli: (suggestions for alternative layout programs appreciated - I'm just trying to find an alternative to Eagle)
05:34 PM roycroft: so far so good - ~20 minutes run time and all the smoke is still inside the spindle
05:38 PM Rab: roycroft, same VFD?
05:38 PM JT-Shop: phipli: this came out nice http://gnipsel.com/images/cleaning-line/cleaner03.jpg
05:46 PM phipli: JT-Shop, what were the raw components?
05:46 PM phipli: you didn't drill all those holes I hope?
05:46 PM roycroft: yes, rab
05:46 PM roycroft: same vfd, new spindle
05:46 PM phipli: roycroft, I hear if you wrap gaffatape around the component it keeps the magic smoke in
05:47 PM roycroft: easy to say after the fact
05:47 PM roycroft: once it makes an escape it's impossible to put it back in
05:47 PM phipli: so, it is 11:45 here and someone has just decided this is the perfect time to dig up the street using a jackhammer
05:47 PM phipli: they're going to get /lynched/
05:47 PM phipli: (not by me - they're a bit down the road)
05:48 PM phipli: roycroft, unless you caught it in a filter?
05:48 PM roycroft: even if you capture you can't put it back
05:48 PM roycroft: the smoke travels one way only
05:49 PM roycroft: that's part of the magic
05:49 PM phipli: http://www3.telus.net/bc_triumph_registry/images/Smokekit2.jpg
05:49 PM roycroft: aha!
05:49 PM roycroft: i found the parameter i forgot to set
05:49 PM roycroft: i could not get full speed with the potentiometer on the control panel
05:50 PM roycroft: so i went back to using the arrow keys for speed control
05:50 PM roycroft: but now i know what to set
05:50 PM JT-Shop: phipli: no the tube was made from perforated plate, I just made and fitted the rings
05:51 PM phipli: http://1.bp.blogspot.com/-jEDPb8qtH9M/UHG_OpAeM9I/AAAAAAAAFM4/26UEhBpNfXk/s1600/space+shuttle.jpg
05:51 PM pink_vampire: what is the "blank" dimentions for 1/8" NPT ?
05:51 PM JT-Shop: for the hole or an external thread?
05:52 PM pink_vampire: I'm trying to use a die
05:52 PM pink_vampire: external thread
05:52 PM phipli: JT-Shop, tidy job
05:52 PM roycroft: a 1/8" pipe is 0.405" in diameter
05:53 PM roycroft: https://www.engineersedge.com/hardware/taper-pipe-threads.htm
05:53 PM roycroft: there
05:53 PM roycroft: pick the dimension you need
05:53 PM roycroft: :)
05:53 PM pink_vampire: but what is the taper?
05:54 PM roycroft: all ntp threads have a taper of 1" of diameter per 16" of length
05:54 PM roycroft: npt
05:54 PM JT-Shop: lol I typed the same typo in a search window
05:54 PM * roycroft deals with time daemons more than tapered pipe threads
05:55 PM pink_vampire: what do you mean by 1" per 16"
05:55 PM roycroft: exactly that
05:55 PM roycroft: if you cut the taper 16" long the diameter will decrease by 1"
05:56 PM roycroft: 62.5mm/m if you prefer that
05:56 PM Wolf__: taper of thread on diameter, is 3/4” per foot, angle of taper with centerline is 1 °47’
05:56 PM roycroft: 3/4"/ft = 1"/16"
05:56 PM roycroft: so yes
05:58 PM pink_vampire: https://i.imgur.com/Rh0jYPB.jpg
05:58 PM pink_vampire: like that?
06:01 PM Wolf__: almost
06:21 PM roycroft: yes, pink_vampire
06:22 PM pink_vampire: cool!
06:22 PM roycroft: rotate that around the x axis and you have a pipe taper
07:52 PM roycroft: well my spindle runout is not within spec, but it's still acceptable - about 0.0005"
07:53 PM jesseg: I guess that'll work for most stuff
07:54 PM roycroft: for woodworking it's fine
07:55 PM roycroft: http://www.roycroft.us/Spindle.mov
07:55 PM roycroft: sorry the focus is poor
07:55 PM roycroft: i need to make a holder for my ipad - i was hand holding it while filming
07:55 PM roycroft: and i was holding it a wee bit too close
08:18 PM absynth is now known as dan2wik
08:24 PM evilroot: Hmmm
08:25 PM evilroot: I need a decent laptop with a parallel port
08:31 PM XXCoder: roycroft: nice
08:34 PM XXCoder: evilroot: laptop tend to be shitty on jag and latency
08:34 PM evilroot: Even a decent one?
08:34 PM XXCoder: yeah so far I know
08:34 PM evilroot: Say Core i5 with 16gb DDR3?
08:34 PM XXCoder: its power management system
08:35 PM XXCoder: probably more dunno
08:35 PM evilroot: Hmm
08:35 PM XXCoder: im sure others can explain it better
08:36 PM skunkworks: evilroot, lots more stuff out there now - but usually laptops are not the greatest. I use mine for testing - using mesa ethernet interfaces. Works pretty good.
08:36 PM skunkworks: acutally really good. ran some real hardware with it.
08:36 PM evilroot: I figured use an Expresscard parallel adapter and a BoB
08:36 PM XXCoder: what was jags test like
08:38 PM skunkworks: pretty good for external hardware - <20us
08:38 PM XXCoder: not bad
08:38 PM XXCoder: my old pc it was 10us or so
08:38 PM skunkworks: this is uspace - not artai
08:38 PM skunkworks: rtai
08:38 PM skunkworks: which usually is worse.
08:38 PM XXCoder: old laptop of mine it was over 100k lol
08:39 PM skunkworks: right - this laptop wouldn't run rtai.
08:39 PM skunkworks: rt_preempt is pretty darn cool - just not usually rtai latency
08:39 PM skunkworks: but 100us is ok for say mesa hardware
08:40 PM skunkworks: or worse even
08:40 PM XXCoder: yeah it handles its own signaling right?
08:40 PM XXCoder: pc dont directly do it. just commands it to do so
08:41 PM skunkworks: kinda - it only requires a servo thread 1-5khz
08:41 PM skunkworks: so the external hardware does the hard stuff - encoder counting, step generation, pwm and such
08:42 PM XXCoder: indeed
08:43 PM XXCoder: pretty cool. maybe will get mesa once I have hardware serious enough for that
08:46 PM enleth: https://i.imgur.com/ryC3Tdj.jpg there you go, some prime sort mechanical porn
08:46 PM enleth: sorry for a shitty photo, I couldn't find a proper camera
08:47 PM enleth: this is an old broken printing press we're taking apart for parts and scrap
08:47 PM enleth: but I'm tempted to keep just one side of it, all shafts cut flush with the back, as a sculpture
08:47 PM enleth: the side in the photo
08:48 PM enleth: if the bearings are beefy enough, and they appear to be such, it should even still move with a much smaller motor
08:55 PM XXCoder: nice
09:03 PM XXCoder: man
09:03 PM XXCoder: some people want better than new price for stuff
09:03 PM XXCoder: kindle paperwhite 2, $100. new paperwhite 3 is $100
09:06 PM MarcelineVQ: there's case where the older ones are better, like if one has a keyboard as actual buttons or not, idk if this is one of those cases though.
09:06 PM XXCoder: it isnt
09:07 PM XXCoder: another one nook simple touch, used, $80,.
09:07 PM XXCoder: theres better looking ones out there for say $15 $20
09:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister1.jpg
09:11 PM Tom_L: chinaco sprayer
09:12 PM Tom_L: need some longer bolts to mount it
09:12 PM XXCoder: its really getting there!
09:12 PM Tom_L: it's all squared up now
09:12 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/X_grid_pattern.jpg
09:12 PM XXCoder: is those toolholders repeatable on tool change?
09:12 PM Tom_L: thought about using that hole pattern
09:12 PM Tom_L: yes
09:13 PM XXCoder: nice
09:13 PM Wolf__: many holes
09:13 PM Tom_L: too many you think?
09:14 PM Wolf__: needs moar
09:14 PM Wolf__: =)
09:14 PM Tom_L: i may cut a groove around the perimeter for coolant drain but i haven't decided yet
09:14 PM Tom_L: you think?
09:14 PM Tom_L: that's 1.25" spacing
09:14 PM Tom_L: offset
09:14 PM Wolf__: I would do some outside the cutting area
09:14 PM Tom_L: on the left and right, i could
09:15 PM Tom_L: i also thought about that
09:15 PM Tom_L: but just ran the dry run on the hole pattern i programmed
09:15 PM XXCoder: you ever used perment marker as tool?
09:15 PM Tom_L: no
09:15 PM XXCoder: I have, and its very nice way to confirm positions so on
09:16 PM Tom_L: i ran the code high and marked it as it went along
09:16 PM Wolf__: coolant drain + make it so you can use the slot to register parts on the table
09:16 PM Tom_L: also may add a few dowelpin holes in various places
09:16 PM Tom_L: could run them inbetween the hole pattern
09:17 PM Tom_L: just offset the grid and run again
09:17 PM Tom_L: i just don't wanna get too many holes and regret it
09:19 PM XXCoder: I wonder if can design it so you could use bolts to make it flush when not used
09:20 PM XXCoder: or big set bolts type
09:20 PM Wolf__: could take some MDF and do a test run
09:21 PM Tom_L: i'm gonna put a plate on top of it to cut on anyway
09:21 PM Tom_L: smaller
09:21 PM Wolf__: mini pallet
09:21 PM Tom_L: it would be ideal if i could find one that rectangle size
09:21 PM XXCoder: "perment" but still replacable plate on top?
09:21 PM Wolf__: I’m planning on making one to use on my mill
09:22 PM Tom_L: yeah, use dowel pins to relocate a new one
09:22 PM XXCoder: thats decent idea if theres say impact it can be fixed by replacing that
09:22 PM Tom_L: i put one on the sherline
09:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Shims/X_Axis_ballnut_shim1.jpg
09:24 PM Tom_L: it's about 2.5x wider than the sherline table :D
09:24 PM XXCoder: I love the milled surface is really curvy and rough illusion.
09:25 PM Tom_L: the flycutter won't reach down that far on the sherline
09:25 PM Tom_L: i didn't make that mistake on the new one
09:26 PM XXCoder: I wonder though
09:27 PM XXCoder: if theres plate on top would it be able to lift a little when cutting say steel
09:27 PM XXCoder: or is there many enough bolta to make it stay down period?
09:27 PM Tom_L: should be ok
09:27 PM Tom_L: that's what my bud uses all the time now
09:28 PM Tom_L: his plate looks like someone took a shotgun to it
09:28 PM Tom_L: all kinds of holes
09:28 PM Tom_L: various sizes for different fixturing
09:28 PM Tom_L: or dowels etc
09:28 PM XXCoder: lol
09:29 PM XXCoder: one of machines at works like that
10:57 PM jesseg: Wow, a 100W RGB LED.. what could I possibly use that for... https://www.ebay.com/itm/202055149849
11:01 PM evilroot: Perhaps for light?
11:01 PM jesseg: I prefer white light for reading and working
11:01 PM jesseg: but there's just something cool about a 100W rgb led
11:03 PM evilroot: Something?
11:03 PM evilroot: I mean it is what it is . . .
11:04 PM evilroot: And the heat output would require serious consideration
11:04 PM evilroot: Perhaps even active cooling
11:05 PM jesseg: yeah I doubt they are any more than 50% efficient or so
11:05 PM jesseg: I see you can now get 100W IR emitting diode modules like that too..
11:07 PM jesseg: which interests me because I want to make an ir strobe for front my my truck right near my dash cam (but outside vehicle) so that it freeze frames the retro reflective effect of license plates so in case of a hit and run, the other guy's license plate gets recorded even at night.
11:07 PM jesseg: Because at night, exposure is too long and license plates end up motion blurred
11:07 PM jesseg: the problem is I'm afraid the strobing IR light may set off the red-light-changer system for ambulances... and that's a crime... Wouldn't want to do it anyway...
11:32 PM ziper: look on my works, ye mighty, and despair https://imgur.com/a/zYPxX
11:33 PM jesseg: Nice, but what is it?
11:40 PM ziper: https://www.youtube.com/watch?v=tr6ao7uT1CU
11:40 PM ziper: dont even know what the mechanism is called
11:45 PM jesseg: oh the flatwind cam follower
11:48 PM ziper: is it really a cam if it is just a rotating lug?
11:50 PM jesseg: well, I guess it's a crank if it has a connecting rod. If it slides on its own axis but is pushed by a cam lobe then I guess I'd call it a cam follower
11:50 PM jesseg: but now I'm splitting hairs
11:51 PM ziper: what is the best way to cut those two slots in the aluminum
11:51 PM jesseg: which two slots?
11:52 PM ziper: picture number 1, on top
11:55 PM jesseg: do you have a small endmill?
11:55 PM jesseg: and a milling machine?
11:55 PM ziper: endmill yes
11:55 PM ziper: mill no
11:56 PM jesseg: Ahh ok how about a flat file and lots of patience
11:56 PM ziper: I did it with a hacksaw after loading up like 6 files
11:56 PM jesseg: oh okay
11:56 PM jesseg: Do you have any friends in town with a milling machine?
11:57 PM ziper: I hope I can dunk them in lye and dissolve the aluminum
11:57 PM ziper: nope
11:57 PM Wolf__: end mill, slitting saw, shaper, table saw
11:57 PM ziper: my question was kind of manual oriented
11:57 PM ziper: doing it with a mill is obvious
11:58 PM jesseg: do you have a courser file?
11:58 PM jesseg: also, dragging the file back on the workpiece can help clean the al out of the file
11:58 PM ziper: maybe I couldve heat treated it to make it a little harder?
11:59 PM jesseg: I doubt it
11:59 PM ziper: I tried the coarsest one I could find, but since it was only like 1/16th my selection was limited
11:59 PM jesseg: yeah
