to inaugurate my new, homebuilt worktable for toying around with resin and similar stuff,
i decided, to try something that should be simple and new (to me)
from the 28mm figures (1:64) modelers i read about things and aplications for materials called the “green stuff” and the “white stuff”.
the white stuff for the molds is something, that gets kneadable from heating in water (they say 170F), then dried and formed around some master. at getting cooler it gets stable, with some flexibility.
to use it again for something else, it has to be heated again.
the green stuff for the copies is just some kneadable two part epoxy, that gets nearly stiff after a time.
i tried to copy a Preiser bread in 1:24, a head, i printed in 1:29, two printed rifles in 1:32 and a little dog from a Kinder egg.
(as i write this, the dog and one rifle are still in the forms)
for mold release i used some vaseline-aloe vera paste, that i had standing around.
looking sharp, it is visible, that the copies tend to become a little bit bigger, than the originals.
i think, i need bigger pieces for the molds, maybe with boxes around.
on one sided copies (like that rifle) i have to scrape away more green material, that they do not become too thick.
and… smearing the mold-release in with the finger, instead of a fine brush, makes for missing parts in the copy (missing nose in head)
