G-10 and equivalent glass-epoxy composites are dirty-expensive if you
to BUY them :) . Here in Finland one company wants about 200usd for a 4'
4' sheet 10mm thick of G-11. The cost is the same for a smaller piece of
sheet as well because of cutting expenses.

Thanks to a friend I managed to acquire a piece of G-10 with
price and talked one company with a special lathe to make it into a
There aren't many companies that will work with these materials - dust
dangerous and diamond-tools are required etc. SO: check before acquiring

How about pheholic laminates with cotton? They are not as good as G-10
much cheaper, easily available etc.. Usign a thicker piece should work

"cotton-enforced bakelite".
