Homebrew PCBs

Manly spindle indeed... but it works great! I have the same setup.

The only question I have is how fast to feed the drill bit into the PCB? I
do not want to feed them too fast so they snap. Yet I do not want to feed
them too slow and thus unnecessarily slow down the drill process and dull
the bits. Does anybody know the recommended chip load per tooth for
PCB-sized tungsten carbide drill bits? I drill at 5 inches per minute at
10000 RPM, but I suspect that's a bit too slow.
