Cutting PCB material both easily and accurately has been a challenge for
me. I have made a PCB cutter using a angle grinder with diamond disc.
After several attempts at trying to cut straight with a angle grinders I
came up with a saw bench arrangment. I made a video to see what people
think.

was the cheapest and simplest way I could think of.
