Hi ...

yes   G10 can be laminated IF    you remove the outer layer of mold release ( a
waxy substance ) with either a good dose of acetone and 180 grit sandpaper  or
a good deal of elbow brease and 120 grit paper...

use either a good 30 minute epoxy or fiberglass resin to bond the plates
together...    as far as pressure ..   use a good sized pot full of water of
several weights tha amount to 10 - 20 lbs ...

with the rpms that you have in mind and the size of electrodes       try at
least 3 layers ( 2 min )  for about 3/8" to 1/2 " total thickness
