Pretty well, but some larger parts are taking a long time to dry. It's cold in my shop, brrrrr. I finally put some of the molds in the oven, that helped. Once dry, I can level the backs and glue on a mounting block for a stand off. There are 23 molds with some parts using the same mold 2x. I didn't know you were so anxious! I thought you were deep into a Pittts build?
