Homebrew PCBs

I have the MicroMark 81631 and I love it. I NEVER break bits even down
to the very smallest holes. The rotation speed could be a tad faster,
but it gets the job done. I use the carbide bits you can get at
harborfreight. They work pretty good.

The MicroMark is belt-driven and very well-built. There is not much
run out on the machine and the deflection when the bit hits the target
is tolerable.

I highly recommend.
