Hello hello,
I am new to customs and casting and have been failing forward so far. Failure is a good learning tool, as is good instruction. Due to availability, workspace and toxicity issues, I have settled on the local equivalent of Instant Mold and Milliput as my mold/cast mediums of choice (if I could get Siligum here, I'd add that and Super Sculpey).
So far I have only had one evening of molding and casting and the results have been poor, but I am satisfied with my progress.
My first mold and cast was a two part pressure molded 2015 Fett Backpack which ended up slightly off register and too heavy (will use aluminum core in the future):
Second was a modified Clone Pilot Helmet that has been my prototype for practicing customizing. Note I made a two part mold with the seam horizontally across the middle, lol.
It turned out ok though, just ugly:
Does anyone have any advice on casting helms Instant Mold and Miliput? I think casting inverted in a two part mold (front and back) with possibly a 3rd part (plug) might be best. However, one would need to build the lego box and molds together, which is different than a silicone pour.
