The Foam-ula for success

The construction of the fiberglass shell for The Numerator 2.0 is moving alone quite well. We started with 7 sheets of Polystyrene foam and masterfully craved them using a new hot wire cutting tool. The packaging of this tool said it would cut through foam "like a hot knife through butter!" One we cut all of the individual pieces of foam, we glued them together and we had ourselves a mold.
We performed a wet lay-up over the foam with fiberglass mat and epoxy resin. Once all the shell is covered with the desired amount of fiberglass, we will break out the foam and dissolve the rest with Acetone. Thanks to Brett, Matt, John, and Brian for their help on the lay up. Here are some pictures of the fruits of our labor.

F'n t!ts - you guys should be wearing masks though for the fumes. Pulmonary lung disorders suck (litteraly).

Cheers and keep up the great work.
