I thought that I was going to mold this first and then cut the new wax up in "slices" for casting but to save a tremendous amount of time, energy, and effort, I've decided to cut the original wax model and cast it directly with no backup mold. This is a bit of a risk because if something happens to the wax or the ceramic investment mold along the way or if the bronze breaks out of the mold during casting, then I lose the piece entirely and I would have to start from scratch again. Risks: sometimes they work, sometimes not. That's life. Onward.
