Carving the Torso Down

I've used a hack saw blade to cut the foam form down into something a bit more torso shaped.
It's worth noting that the foam isn't like styrofoam.  It's a tough plastic, and cutting it like this made a terrible mess of sharp sand sized bits that got everywhere.

Initial Foam Torso

The best part about a duct tape mold is that you get to destroy it. This is the foam torso I had left after the mold was done. It doesn't much look like a torso yet, but give it time.

Mold Breaks

At this point I realize I've maybe used too much polyurethane mix.   The plastic bag & duct tape mold inside is swelling up, and has actually knocked out the cardboard frame at the bottom. 

Science Is Fun

The mixing begins.
Timing here is important.  I want the chemicals intermixed completly, but if I mix too long it will start to foam while I'm still handling it.

Torso Mold

The first mold I made for my Eviscerated Torso project Halloween decoration.

I took the easy way out and used a combiation of cardboard, plastic bags, duct tape, and an old shirt. The old shirt helps define the shape.

The cardboard tube down the middle is to ensure the opening forms correctly. The open bag is where the two part polyurethane solution will be poured.

Project: Eviscerated Torso

Two part polyurethane is a fun little chemical. It mixes, and about 20 seconds later it foams up with a great deal of heat. A few hours latter it turns solid. It's also rather nasty stuff. It tends to stick to, or eats away at, all sorts of stuff. Thus the big gloves, as it's famous for merging with skin on contact. It doesn’t smell great either.
