Ok, I'm trying to generate a Vader faceplate for my upcoming ANH kit. I'm using a 2nd hand DP Classic Action faceplate as a base and have already molded it, thinking I could just sculpt in the smaller goatee grill in the chin.
BUT, after pulling a casting, I noticed his cheeks are sunken in more than I like and I want to spread them out a little more flush. I've tried using a heat gun to soften the cured resin, force them out and hold them till they cool, but it's just too much curve, and they keep going back.
What I need to try now is pull another casting, pull it while it's still soft, and block it in place with something till it cures. A square block of foam would be perfect, but there's none to be had right now, and I'd really like to get this done tonight.
I made a "cheek spreader" a couple weeks ago, out of a small turnbuckle with a couple rubber furniture feet on the ends, but it's almost too big, plus I'm afraid it'll just push out big bulges where the rubber feet are. I "think" I could cut some thick plastic plates to put on the ends and spread the force evenly, but I don't know if there would be enought room between the rubber feet and the actual resin cheeks.
Anybody have any ideas?
