Homebrew PCBs

You can use anything you want as a carrier, but the top surface of 
the PCB MUST be grounded while the print is being made. If you use a 
non-conductive carrier you can use copper foil tape and a grounding 
clip that disconnects before reaching the drum. Metal seems easier to 
me, but ...?

The drum does not seem to be that fragile. I do lightly file the 
other three edges of the pcb.
