Nifty stuff, what is sculpty???Where do you get it?
bbaumer07-Apr-08 17:45
Sculpy is a synthetic oven baked clay, similar to Fimo. Most any crafty store has it, Hobby Lobby for sure. The best part is is somewhat machinable after you cook it.

Cook it...what do you mean??
bbaumer07-Apr-08 18:11
you bake it in your oven at 175 degrees for 5 minutes per 1/4" of thickness or so
bbaumer07-Apr-08 18:12
actually, I just re-read, it's 275 for 15 minutes per 1/4"

Push into spinner, remove and bake...is it sandable?
bbaumer07-Apr-08 18:21
yes it is, I had to work the back edge pretty significantly to get it square. It is pretyt hard, but workable. I sprayed the vacuum formed with water as a mold release, it seemed to work really well, some learning curve getting it out without distorting it. You can see how smooth a standard drill bit bored the hole in the scoop. Also, thats a .a25 aluminum tub I inserted from the rear ( drilled after baking ) that also acts as a working shaft on the prop.

I am impressed. I will use this in the future. Seems like an easy way to cast parts from vacuformed plastic! This, me thinks ,is wonderful!
