I have concerns as well for the melting temp of Plexiglas. I'm going
to put together a G10 disk as soon as I can get my hands on some. I
lathed some stainless steel electrodes and insulating standoffs to mount
them into a lower temperature tolerant disk (i.e.. Plexiglas) but I'll
install them in the new disk as soon as I can cut it.
*Does anyone know of a good supplier of 1/2" G10 preferably already cut
into a disk shape?*
Thanks for your response.
