01:03 AM rue_mohr: it was on a webpage3
01:17 AM rue_mohr: we were all excited because it was self-regenerating
01:17 AM rue_mohr: https://jimlaurwilliams.org/projects/seychellePaper/
05:07 AM Tom_L: i rememer it but never used any
08:53 AM VanUnamed_ is now known as VanUnamed
12:00 PM rue_mohr: I'm not a chemist
12:01 PM rue_mohr: and it takes a long time to get the first batch set up
12:01 PM rue_mohr: but years ago I started some
12:01 PM rue_mohr: and I dont know how to adjust it properly
12:01 PM rue_mohr: so its not in the right state to use
12:01 PM rue_mohr: thats my whole point
12:02 PM rue_mohr: right now it would tear the resist off before finishing the etch
02:36 PM rifraf: found a possible thrust bearing that would fit https://www.motion.com/products/sku/00653814
03:20 PM aandrew: I don't know that I'd go back to a chemical self-etch, I think I'd probably put the time/money/energy into a PCB mill before faffing about with chemicals again
05:46 PM rue_mohr: I dont fancy the mechanical compromizsation
06:11 PM rifraf: i like the chemicals, you just need to get your method correct
06:14 PM rifraf: batch of pretty radii https://desire3d.com/images/public/radii.jpg
06:15 PM rifraf: now that i can make these gonna try sell them to everyone who already has a top, much bigger market
06:15 PM rue_mohr: what are they?
06:16 PM rifraf: brass rings
06:17 PM rue_mohr: nice
06:17 PM rifraf: https://desire3d.com/webshop/index.php?rt=product/product&product_id=131
06:17 PM rue_mohr: are they stacked 4 high?
06:17 PM rue_mohr: or have ridges?
06:18 PM rifraf: no, they are stacked 5 high in that image
06:18 PM rifraf: each one only 9.5 (3/8") high
06:19 PM rue_mohr: ok
06:19 PM rifraf: they are just a blank currently
06:20 PM rifraf: outside to be machines and engraved as required, then polished, hard part os getting them to this point
06:20 PM rue_mohr: and their brass, so chome plating can be a thing
06:20 PM rifraf: ok\
06:20 PM rifraf: diy?
06:21 PM Tom_L: sexy
06:21 PM Tom_L: done with your ground tool?
06:22 PM rifraf: yep
06:22 PM rifraf: and a bit of 400 grit paper then a quick polish on radius and inside
06:22 PM Tom_L: do you coat them so they stay shiney?
06:23 PM rifraf: no
06:23 PM rifraf: the polish i use stops some tarnish
06:23 PM rifraf: but is nice top let people polish them up themselves, they will still darken
06:24 PM rifraf: will supply with high polish, but is natural brass, and will do what brass does
06:25 PM Tom_L: sell a polish kit too :)
06:25 PM Tom_L: or dip em in muratic acid
06:25 PM Tom_L: that works real quick
06:25 PM rifraf: yeah good idea, need a tiny vial to put this polish in
06:26 PM rifraf: a few drops goes a long way
06:26 PM Tom_L: uline
06:26 PM rifraf: acid to clean them?
06:26 PM Tom_L: maybe not in the Au but here
06:26 PM Tom_L: no
06:26 PM Tom_L: but i did use it to clean brass to shiney then cleaned off the acid and put a clear coat on
06:27 PM rifraf: yeah clear coats will look crap after a while of getting bumped i think
06:27 PM Tom_L: could be
06:27 PM rifraf: and then make it really hard to try polish
06:27 PM rifraf: i am using the selling point of bumps and use add character
06:28 PM Tom_L: may as well
06:28 PM rifraf: and with bare brass even a quick polish with anything and a cloth will give results
06:30 PM rifraf: ok off to the dump quickly and then back to cutting OD radius on the smaller ones
06:30 PM Tom_L: chop chop
06:30 PM rifraf: Tom_L did my ecommerce site open ok for you?
06:30 PM Tom_L: yep
06:30 PM rifraf: is a WIP, i really wanna try get it working
06:31 PM rifraf: paying money for nothing

06:35 PM Tom_L: he had a bout with google bots a few times
08:03 PM rifraf: i noticed quite a few clutch throwout bearings was uni directional, like a sprag bearing, this common?
08:03 PM rifraf: cause i need to be sure i can go both ways
08:16 PM Tom_L: only needs thrust in one direction
08:16 PM Tom_L: that or use a deep groove ball bearing
08:19 PM rifraf: i mean spinning in only 1 direction
08:20 PM rifraf: the thrust is only 1 way
08:31 PM Tom_L: i dunno

10:50 PM Tom_L: commercial i think but it
10:50 PM Tom_L: it's kinda weird
10:50 PM Tom_L: i think it uses threaded holders the spindle comes down and threads into
10:51 PM Tom_L: i'm just trying to get him a template to work from. he doesn't know much about it
10:52 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/Toolchange3.mkv

10:57 PM Tom_L: https://www.youtube.com/watch?v=wsUm0P3TmAM
11:01 PM rifraf: interesting, and for er11 as well, must be nice and small
11:01 PM Tom_L: i've never seen threaded holders like that
11:01 PM rifraf: not seen either
11:02 PM Tom_L: he had no clue where to start with M6 remap
11:03 PM Tom_L: and it's only 4 tools
11:04 PM Tom_L: you run all your machines metric right?
11:04 PM Tom_L: i had to convert to inch so i could work on it then put his numbers back in once i had the paths sorted out
11:29 PM rifraf: all metric yes
