Homebrew PCBs

I've used a small (4") composition metal-cutting blade for a zip router. It
makes a nice clean cut with a small kerf (about 0.05") but you need to do it
outside with a fan to blow away the dust and smoke. That dust will kill you.
I built a small wet saw using the same blade which worked well but was too
messy. I think my next step will be to get a shear if I can find one the
right size and cost. I cut a couple of boards on a table saw with a 10"
plywood blade which is now dull as a result and must be replaced. That
fiberglass dulls everything but carbide or diamonds. I have a 16" paper
cutter but I don't want to take a chance on dulling it since I just finished
sharpening and refurbishing it.
