Homebrew PCBs

Hello Buckeyes1997,

90 degree cutter cut was very smooth without any burr. But, it did not
provide much leeway when the pcb is not very smooth. Even a mil difference
was leaving small islands of Cu.

Did you use the 90 degree cutter from here?

Is that an FR-4 board or a paper phenolic board? btw, What is the size of
the smallest trace on that pcb in the photo?

Have you tried other bits before deciding on the 90 degree cutter bit?

Thanks
Joe
