I’ve used Frank Goss’s technique for making sheet wax when I needed a
special thickness. One problem I ran into was how to get a uniform
thickness. The way I solved it was with a few coins.
Frank mentioned how to melt some wax, pour it onto a piece of
Plexiglas, and press another sheet of Plexiglas down on top of it. My
tip is to first put 3-4 coins (or spacers of the right thickness) on
the bottom Plexiglas. Then pour the wax and press the top sheet down
