Making A One Piece Cut Block Mold

The rubber is poured from a height in a thin stream into the lowest spot in the mold box. The high pour and thin stream will break any bubbles that remain after the vacuum chamber. The material is allowed to rise and surround the model at its own pace, gently displacing all air in the process. The rubber is poured to at least a half inch above the top of the model and allowed to cure overnight.
