01:34 PM Tom_L: saddle up and ride into town
03:35 PM aandrew: hm, any tricks to getting RTV based caulking (exterior, white) to cure faster as a molding material? it's the material I'm molding, not what the mold is made out of
03:35 PM rue_mohr: fire up the car, get a good head of steam up for the trip
03:36 PM rue_mohr: aandrew, yes, mix some
03:36 PM rue_mohr: mix in some

05:54 PM Tom_L: also my grandfather made me one as a child
06:10 PM aandrew: oh I think you told me that cornstarch trick already
06:11 PM aandrew: it's already in the mold for 24h now but still wet, we may have to abort this attempt
06:15 PM Tom_L: rue_shop7, don't look to the past, look to the future and make a fission powered engine
06:22 PM aandrew: if you're really forward-looking, skip fission and move straight to fusion
06:22 PM aandrew: and you're up in canada, so it's already cold fusion
08:59 PM rue_shop7: yes but I cant go out to the forrest and get nuclear fuel for free
09:00 PM rue_mohr: There is energy borrowing, but BAD things happen if you dont return it
09:00 PM Tom_L: ok A8 is on the same fixture plate now
09:06 PM rue_mohr: hu?
09:06 PM rue_mohr: A9/10 is the only 1/8" material tho
09:07 PM Tom_L: just moved it down a bit and can run it off the same plate with different material
09:07 PM Tom_L: so once the plate is set i can run both
09:07 PM rue_mohr: er, ok
09:09 PM Tom_L: and it drills the holes for the next part in line so all i do is slide the sheet down a bit for the next one and screw it in place
09:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A8_fixture.jpg
09:29 PM Tom_L: i have 2 locating pins on the left one gets moved left after drilling the holes in the right part then it moves left for the profile
09:29 PM Tom_L: that way i can just keep moving the plate left .750"
09:54 PM rue_mohr: oooh yea, cool
09:54 PM rue_mohr: yea I'm cutting some of those now
09:54 PM rue_mohr: the tiny hole is actually 1/16"
09:55 PM rue_mohr: I dont have enough horizontal room on the sherline, so I have to make blanks for 3
09:55 PM rue_mohr: my offset is 20mm
09:56 PM rue_mohr: looks like you have yours a bit tighter, I had problems with the tabs when I got them too close
09:56 PM Tom_L: no tabs
09:57 PM Tom_L: just profile and hold with a 1/16 dowl and bolt
11:06 PM rue_shop7: I think I'll have to see it
