I am building my heated bed.
I have a 12X8 1/4 thick Pyrex glass top
a 12.25 x 8.25 PCB hot plate (MK1)
The problem is that it has a slight bow to it and I need to sandwich it against something to get it to flatten against the glass.
I was going to use 3/16" thick aluminum and design in some aluminum edge clamps that grip the very outmost edge of the glass and press it against the aluminum plate beneath the heater.
Is aluminum the best way to go or is there a better material. I know aluminum absorbs a lot of heat so I would think it would make the hotplate more inefficient.
Should I maybe use 1/4" think phenolic or some other material beneath the hotplate???
