08:01 PM rue_shop5: huh
08:01 PM rue_shop5: didn't set myself out a good mix of tasks
08:10 PM rue_mohr: I'm making up 10 of the SG90 potentiomers
08:23 PM rue_mohr: -- weekend --
08:23 PM rue_mohr: - fix marker lights on mecha
09:01 PM Tom_L: i made a few things from fiberglass

09:06 PM Tom_L: 2' ish
09:06 PM rue_mohr: ah
09:06 PM rue_mohr: cool
09:06 PM Tom_L: 60cc
09:06 PM Tom_L: ? i think
09:06 PM rue_mohr: thats not small
09:06 PM Tom_L: then it wasn't 60cc
09:07 PM rue_mohr: 049?
09:07 PM Tom_L: no bigger
09:07 PM rue_mohr: huh
09:07 PM Tom_L: by 2-3 sizes
09:07 PM rue_mohr: so
09:07 PM rue_mohr: with my truck
09:07 PM Tom_L: some did scale of the thunder boats
09:07 PM rue_mohr: I went to scrape off some of the bubbling pain
09:07 PM rue_mohr: t
09:08 PM rue_mohr: and, thats all that was there
09:08 PM Tom_L: no surprise there
09:08 PM rue_mohr: so, I'd like to fix it up
09:08 PM Tom_L: rust?
09:08 PM rue_mohr: no, just paint
09:08 PM rue_mohr: even the rust was gone
09:09 PM Tom_L: get some galvanized sheet and make it the right shape and tig it in
09:09 PM rue_mohr: well
09:09 PM Tom_L: cut back til you find good metal
09:09 PM Tom_L: (me did some body work too)
09:09 PM rue_mohr: the thought was that if I replace it with fiberglass, it wont rust again
09:10 PM Tom_L: not the best idea
09:10 PM rue_mohr: ?
09:10 PM Tom_L: i mean, you can but a proper repair would be new metal
09:10 PM rue_mohr: but then it would rust out again
09:10 PM rue_mohr: in another...
09:11 PM rue_mohr: 32 years
09:11 PM Tom_L: then you coat the welds with spray tar
09:11 PM Tom_L: on the underside
09:11 PM rue_mohr: inside
09:12 PM rue_mohr: front quarter
09:12 PM rue_mohr: but, it should come off..
09:12 PM Tom_L: or find a quarter and replace the whole thing
09:12 PM rue_mohr: I think its a problem they all had
09:13 PM Tom_L: i did a little bit of rust repair on mine before that kid bought it
09:13 PM rue_mohr: mhm
09:13 PM rue_mohr: how big were the spots
09:13 PM Tom_L: i had to fix the cab mounts for one
09:13 PM rue_mohr: yea, mine seem ok
09:13 PM rue_mohr: I'v heard that a few times about those tho
09:13 PM Tom_L: nothing fancy there
09:14 PM rue_mohr: maybe its not a problem for mine on account of all the oil spilled in the cab
09:14 PM Tom_L: heh
09:14 PM rue_mohr: mostly leaks out those funny ports they put under the mats
09:15 PM Tom_L: https://www.ebay.com/b/Fenders-for-Chevrolet-S10/33644/bn_1354242
09:15 PM Tom_L: some of those look newer
09:15 PM rue_mohr: 500 is ouch
09:16 PM Tom_L: salvage
09:16 PM Tom_L: i got a rear bumper salvage once
09:16 PM Tom_L: somebody rear ended me
09:16 PM rue_mohr: our yard here scraps EVERYTHING
09:17 PM rue_mohr: hey, you in the mood for a bit of math
09:17 PM rue_mohr: ?
09:17 PM Tom_L: 1+1=1
09:17 PM rue_mohr: heh
09:17 PM rue_mohr: not much worse
09:17 PM rue_mohr: the input to a fn is 352-304, the output is 0-100
09:18 PM rue_mohr: its a backwards relationship
09:19 PM Tom_L: -2.0833
09:19 PM Tom_L: ratio
09:19 PM Tom_L: ?
09:19 PM rue_mohr: out = (I-304)*-2.0833
09:19 PM rue_mohr: ?
09:20 PM Tom_L: i've no idea
09:21 PM Tom_L: it's like a 1" tube of liquid pushing a 2" tube
09:22 PM Tom_L: 0 - -48 = 0 - 100
09:22 PM rue_mohr: yea, I'm at 100-(I-304) * 2.083
09:23 PM Tom_L: or 48 - 0 = 0 - 100
09:24 PM rue_mohr: out = I*2-533 might work
09:26 PM rue_mohr: wow that .083333 is really important
09:28 PM rue_mohr: er
09:30 PM rue_mohr: 100 = (I - 304) * 2.083333
09:30 PM rue_mohr: skljfkljasdf
09:30 PM rue_mohr: 100 - (I - 304) * 2.083333
09:30 PM rue_mohr: work
09:30 PM rue_mohr: s
09:30 PM rue_mohr: so, 100- 2.083333*I - 633.333
09:31 PM rue_mohr: so
09:31 PM rue_mohr: -2.083333*I - 533.33333
09:32 PM rue_mohr: wtf
09:32 PM rue_mohr: did I do that wrong
09:32 PM rue_mohr: ?
09:33 PM rue_mohr: out = 100 - (I-304)*2.083333
09:33 PM rue_mohr: 304 -> 100
09:34 PM rue_mohr: 352 -> 0
09:39 PM Tom_L: see you didn't need me after all
09:39 PM rue_mohr: your nailed the important part right away
