Knife mould

This was my first major mould.  I get my materials from Askew Taylor in downtown Raleigh NC.  They have a great selection of almost anything ay artist would ever need.

The mould is a silicone rubber compound.  The sides of the mould are really rough because I didn't use enough mould release, so the silicone fused together and had to be ripped apart. 

These pieces of wood were used to hold the sides together and the clamps were used to clamp the wood together.  The mould was filled with a liquid plastic and allowed to harden for the appropriate amount of time.

The mould worked a lot better for just the handles.  As you can see the blades of the knives got a lot of air bubbles trapped in them from the design of the mould and the plastic proved so thin that it easily broke off.  Lesson learned, a harder plastic is needed to cast knife blades!

All the white is the cast and the black is the original.
