03:54 PM Tom_L: bet you're glad
03:54 PM rue_mohr: tommorow I head into vancouver , stay overnight and friday morning do the provincial test
03:55 PM rue_mohr: THEN I'm off the hook
03:55 PM Tom_L: you get a gold star if you pass?
03:55 PM rue_mohr: (if I pass)
03:55 PM rue_mohr: red seal
03:55 PM Tom_L: beats a kick in the arse
03:55 PM Tom_L: feel ready?
03:56 PM polprog: opamp exam tomorrow...
03:57 PM Tom_L: i never quite understood them
03:57 PM Tom_L: in out and gain but meh
03:57 PM polprog: i mean, 99% you just need that picture with the configurations and the cheat sheet
03:57 PM polprog: 99% cases
03:58 PM polprog: funny thing, if he gives only 20 minutes to solve, sign, scan and send that ill be pissed
03:59 PM polprog: mostly because we were doing a basic task of finding out gain vs frequency for 1h for each example amp in class
03:59 PM polprog: and the example were pretty much a noninverting amp with a cap instead of one of the resistors, or an inductor added in series in the feedback loop
03:59 PM polprog: cretins
04:00 PM polprog: the topic is easy, its just the exam that was made unnecesarily hard
04:14 PM rue_shop1: Tom_L, never

05:06 PM rue_mohr: there is the sensor and the schematic so far
05:07 PM rue_mohr: I'd like to put a 4-20mA interface on it, so I can make a bunch and bring them all back to a single ADC
05:16 PM Tom_L: ok so i extended the slot in the material stop in this video: https://www.youtube.com/watch?v=Ga9n4Laub1Q&feature=youtu.be
05:17 PM Tom_L: as a test i did full depth with a 3/16 cutter and nothing broke
05:17 PM Tom_L: slowly :)
06:16 PM rue_mohr: :)
08:02 PM aandrew: https://imgur.com/a/jtQbAyv might interest y'all

08:45 PM rue_mohr: hahah
08:46 PM rue_mohr: the components for the sensor total 0.90
08:49 PM Tom_L: :)
08:49 PM Tom_L: aandrew, cute
09:00 PM rue_mohr: thats a rapid rapid
09:01 PM Tom_L: 210? ipm
09:03 PM Tom_L: cutting @ 10ipm
09:23 PM rue_mohr: oh THIS is why I'm not supposed to go near imugr
09:34 PM rue_mohr: so, why does that chuck look like it has a really big dent in it?
09:35 PM Tom_L: haha i posted the wrong pic here
09:35 PM Tom_L: that's for an okuma kadet
09:36 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Softjaws2.jpg
09:37 PM Tom_L: i think that's a thin cover for the center of the chuck. ours didn't have that since it had a feed tube out the back
09:37 PM Tom_L: it was open
09:38 PM Tom_L: the smaller screws you see are holding the cover
09:39 PM rue_mohr: you use jaws as jigs dont ya?
09:39 PM Tom_L: easy to do
09:39 PM rue_mohr: I think of them as someth9ng you want to last forever
09:40 PM Tom_L: you make em tall enough you can just saw the top off and go again
09:40 PM Tom_L: my steel ones i do
09:40 PM Tom_L: we used those all the time at my friend's shop
09:41 PM Tom_L: we kept them for the next job run but i just mill mine off and use them again or cut over the first project
09:42 PM Tom_L: i've done that a time or two
09:42 PM Tom_L: as long as there's enough profile in the jaw to hold the part...
09:42 PM Tom_L: you printed those for the sprayer didn't you?
09:43 PM Tom_L: i forgot which part that was now
