[TCML] Cutting Garolite disk

[Joe Mastroianni <joe@xxxxxxxxxxxxxx>]

Ok,
So I'm making a srsg and I am convinced of the primacy of garolite as  
the material to use for the disk holding the spinning electrodes. But  
as far as I can tell my sources of garolite will all provide square or  
rectangular chunks (eg - mcmaster-carr)

What's the best technique to cut a precise circle out of these square  
pieces?

I don't have a band saw...

Thanks in advance
Joe
