12:00 AM zhanx: cheaper to order from amazon
12:05 AM zhanx: be here saturday and cheaper than gas driving there
12:09 AM rue_mohr: so, there is a thing
12:09 AM zhanx: a thing
12:09 AM rue_mohr: 3d print
12:09 AM rue_mohr: then cast in silicone
12:09 AM rue_mohr: then use to make wax positive
12:09 AM zhanx: nice
12:09 AM rue_mohr: then use plaster to lost wax cast
12:10 AM rue_mohr: (x many)
12:10 AM rue_mohr: corn starch works great as a release powder for silicone
12:12 AM rue_mohr: I need to make some tapered pins too
12:12 AM rue_mohr: oh :)
12:12 AM rue_mohr: and a "made in canada" stamp for my casting sand!
12:14 AM zhanx: one of the old guys here, thinks i am not eating right and brought me food.
12:14 AM rue_mohr: k
12:14 AM zhanx: yep not eating whatever that chicken stuff is
12:14 AM rue_mohr: did he get old eating it?
12:14 AM zhanx: i have no clue
12:15 AM zhanx: its like a chicken soup thing with stuff in it that is not a noodle
12:15 AM zhanx: zero flavor
12:15 AM zhanx: its pure salt I think
12:15 AM rue_mohr: hmm
12:16 AM rue_mohr: I'm NOT big on foods I dont already eat
12:16 AM zhanx: i took it tasted it, said nice things, gonna flush it
12:16 AM zhanx: I eat a lot of veggies, I guess that is the issue?
12:16 AM zhanx: whats wrong with fish and rice. etc
12:16 AM rue_mohr: heh ;) find a nice comment that encourages him to not bring you more
12:17 AM zhanx: i will say tomorrow it didn't agree with me and kept me up all night. hope that works
12:18 AM rue_mohr: hah, since reading that book I cant look at casting the same way
12:18 AM rue_mohr: book
12:18 AM zhanx: Since forge is done and the bottom works as a pizza oven, I am making pizza tomorrow
12:18 AM zhanx: cauliflower as the dough
12:18 AM rue_mohr: I have no desire to cast in 10% horse manure, but I keep considering that I dont need a 1:1 positive of what I want to make
12:19 AM rue_mohr: carefull of toxic metalness
12:19 AM zhanx: yea I can send you the horse poo if you want it
12:19 AM zhanx: pulling the pipe out of it
12:19 AM rue_mohr: hahahaha
12:19 AM rue_mohr: pass
12:19 AM zhanx: then its all brick
12:21 AM rue_mohr: damn, I have a HUGE queue of ideas with casting that will take SO LONG to try
12:21 AM zhanx: you?
12:22 AM zhanx: I want to cast a 3d cement printer
12:22 AM rue_mohr: hmm, sounds big and heavy
12:22 AM zhanx: it will be
12:22 AM rue_mohr: I want to make flask alignment pins
12:22 AM rue_mohr: holders
12:22 AM rue_mohr: things
12:24 AM zhanx: that is on my todo list
12:25 AM rue_mohr: I been making them with angle iron and there are design issues
12:25 AM zhanx: well, i got 15 piece of 20 foot 2x12"
12:25 AM zhanx: to play with, they are old
12:27 AM zhanx: I want to make a solid, solid table with them
12:29 AM rue_mohr: k
12:29 AM zhanx: issue I got is not the material but the size
12:30 AM zhanx: 4x4 or 6x6 so can pour on it
12:33 AM rue_mohr: keep the pouring low
12:33 AM rue_mohr: and there will be spillage
12:34 AM rue_mohr: a sand pit is a good idea
12:34 AM zhanx: well the table is going to be a sand pit / model / mold area
12:34 AM rue_mohr: k
12:34 AM zhanx: 6" deep min
12:35 AM zhanx: helps me not have to bend over for the back
12:36 AM rue_mohr: k
12:36 AM rue_mohr: splasing molten aluminum is a bad thing
12:36 AM zhanx: yep hence the high walls
12:36 AM zhanx: and not bending over is one less movement
12:37 AM rue_mohr: I was pondering the idea of a pot crane
12:55 AM zhanx: lol the town i am in is on tv for most dangerous videos
08:39 PM rue_shop1: ok, gonna try to use the corn starch release trick with the silicone to make a custom stamp
08:41 PM rue_shop1: or maybe I should use wax first
08:41 PM rue_shop1: ooo
08:43 PM Tom_L: baby powder should work too
09:04 PM rue_shop1: apparently cornstarch helps it set
09:09 PM Tom_L: no idea
09:18 PM rue_shop1: <ad warning>

09:20 PM rue_shop1: https://makezine.com/2010/11/04/reader-research-diy-casting-silicon/
09:20 PM rue_shop1: ^ not as bad on ads
09:22 PM Tom_L: i used to use a glass like additive (glass bubbles) to fiberglass resin as a filler
09:22 PM Tom_L: very sandable
09:26 PM Tom_L: what are you making with it?
09:35 PM rue_shop1: I have a bunch of ideas to try on things
09:35 PM rue_shop1: I'm playing with a stamp as one of them
09:35 PM rue_shop1: -- no materials --
09:35 PM rue_shop1: the accountant cant understand me leaving the material section of a job sheet blank
09:35 PM rue_shop1: they also dont understand me crossing it of
09:35 PM rue_shop1: off
09:36 PM rue_shop1: so I have to write "-- no materials -- " on each one
09:36 PM rue_shop1: they also cant understand me not writing the source as "stock" on EVERY line item I pull from stock
09:37 PM rue_shop1: but I want to try some of this intercasting stuff
09:37 PM Tom_L: so what are you gonna use for the text mold?
10:01 PM rue_shop1: 3d print
10:01 PM rue_shop1: well, it was a bit fine for that, I might need to try a sub-1mm bit
10:02 PM rue_shop1: but that would also need patience, so ~
