Had a successful pour today of 4 of the heads for the benches.
Here are a couple pictures of resin bonded sand molds for cardboard patterns. Note how thin the molds are. That is because there is only a thin piece of cardboard in each mold. Although the cardboard pattern is 3/8ths of an inch thick the mold needs to be 4 inches thick to keep the 2,000 degree metal from burning out of the mold. The 3 benches will require 3,300 pounds of sand and 600 pounds of bronze.
These are the faces that I will be casting for the benches. I have included pictures to give you an idea how they will look together with backs and arms. It’s hard to put them together in cardboard with tape as they just collapse from their own weight. fortunately when they are solid bronze they hold up much better.
