The real solution would be a source of fresh foam
pads....
I could use a few sets.
Easy for us: Go to any shop who sell leather tools and buy a "hole
puncher". It is a stick with a hole in one side, and a sharp border. You use
that with a hammer to create round roles in leather. Buy one with the
INTERNAL size of the foam pads you want. Now you just need to find some
scrap foam and a table of wood. You can cut as many foam pads as you want
:o)
hope that helps
