I am having difficulty finding some cheap epoxy/fibreglass sheet to use 
for a RSG. I was wondering if anyone has ever tried using well dried 
and prepared plywood? While it isn't the best insulator, I would 
imagine that a polyurethane coated disc of about 10-12" diameter would 
probably insulate well enough. Another plus is that high grade plywood 
can be very strong and is probably better at handling high temperatures 
than most plastics. It is also cheap and easy to work with. You could 
even impregnate the wood with polyurethane/acrylic/epoxy, etc using a 
vacuum. What do you think?
