Head Start is an early educational experience for low income rug rats. 7 of the last 8 years my wife and I have made small graduation medallions for local head start students on a volunteer basis. A child's first graduation should be a little special.
Making the molds in a stack is very efficient for mass producing "one-sided" castings.
Center dowel forms sprue cavity.
Smooth with trowel. Rap with rammer to loosen.
Flip on to board. Remove pattern box.
Patterns are too close to edge, leave at least 1/2 inch. Carefully place on stack.
Stacks after pouring!
