Homebrew PCBs

I don't agree with the requirement of a 16,000 RPM spindle.  I am using a large woodworking drill press set at about 2000 RPM and have no problem at all drilling holes in circuit boards. It would be better to have the higher RPM, but there is no reason at all you cannot use a lower speed spindle.
