Homebrew PCBs

If you have occasion to find a used Cameron micro drill press, don’t hesitate to buy it. They are extremely precise and can run up to 30,000 RPM. I bought a model 164 with the standard 1/8” Yukiwa drill chuck, and had a very difficult time measuring any runout with a Starrett Last Word DTI run against the shank of a carbide drill bit. Specified spindle runout is only 0.0002”, or 0.05 mm.


The only drawback, if there is one, is that the maximum depth of work is a bit limited, but much less so than with the Dremel. I’ve only broken bits by bumping the work piece against the side of the drill.


All the best!
