Fascinating, I bet.
You pretty much answered my question. If its going to be used as a general tool
then it could end up becoming indispensable for the home workshop. In this case
then it should be built for milling capability. For exclusive PCB hole drilling
then a well designed hand operated drill press does the job without a drama.
