Homebrew PCBs

When I have cut pcb material on my table saw I taped up a bunch, with
masking tape, and ran them thru so that the thickness would be at least a
half inch thru the cut.

 

I think a good table saw blade for this purpose would have many teeth, like
an 80 tooth diamond faced blade, which are available for 10 inch, which I
have and 8 inch, 12 inch, 4 inch I am not sure.

 

Some of the pcb material I think would not survive the table saw and a band
saw with a metal cutting blade might be better.

 

Sorry I cannot give a more precise response.

Can someone recommend a good blade pitch for that task?

Get a Wet/Dry Diamond Blade.

Saftey: Most any of the Wood Workers rules would also apply to cutting
PCB's.

1. Keep your fingers away from the blade when running.

2. Wear Saftey Glasses.

3. Setup good Dust Collection.

4. Panel cutting jig that you can clamp your material to.
