Time to make the parting board.This done so it can be a 2 part mold. This the top of the mold. Start out with mold clay to hold the plug in place on the back side of the parting board. Then on the top i use parifn wax to seal the plug to the paring board. Let cool down for a few hr. and start the job of scarping the wax to get a clean edge this is a 90 degree. So you can get a square edge.
