I followed some advice from a friends wife who works with prosthetic make-up appliances.  Who suggested I make a rig to really hold the mold closed.  It’s really cut down on the running looking like an idiot while white plastic gets stuck in all my finger hairs.  The models do come out cleaner,  but they are a little bent from the wood putting pressure on different parts of the mold. But I think I can fix that with some sanding and a little Epoxy clay. 

Also,  utility knives are sharp.
