How To Make a 2 Piece Silicone Mold to Cast a Police Baton Prop

Begin by building a containment box to accommodate the original model. Spread a 1/2'' bed of non-sulfur clay along the bottom of the box and then place the original into the box.

Build clay around the original until one half of the piece is embedded. Use clay sculpting tools to cut registration keys into the clay bed. Add additional keys. Keys help the two-part mold stay properly aligned from cast to cast.
