My first negative silicone mold attempt that I'll use to make a positive silicone. Them I'll use it to make my negative plaster mold. In the final third picture, the mold came out quite well except for a few bubbles around the bolts. This was a result from most likely not vacuum degassing the silicone before I poured. I would have except I have yet to make a vacuum chamber and get myself a pump. Those are on the list next.
