After recently obtaining a used hydraulic press, I googled “how to
make matrix dies” and found some instructions that I followed: 16
ga. steel sheet on top of tempered masonite over 3/4" plywood. I cut
equal squares of each material, then separately marked and cut out
my desired shape. The problems I had: the plywood seemed to crush at
least 1/8" after only a few pressings, and I didn’t know how to
successfully attach the 3 layers together (rubber cement didn’t
hold). Also, cutting the square of steel was time-consuming- could I
use a lapidary trim saw (or something else?) for that task (and save
my jeweler’s saw for the die shape)?
Any suggestions other than to buy some already made? I’ve already
invested money in raw materials and would like to make this work.
