That looks impressive. I guess those are bipolar motors that you
attached to gear reducer heads and control with a serial/parallel
port? That is interesting that you were able to use brackets that a
person can buy at most hardware stores I guess. Can you use a drill
file from software like Eagle to do all the drilling from the diagram
automatically? I guess because you have to change the drill bits by
hand, you have to edit the drill file then. Are you using a chip like
the HIP4081A or a PIC like PIC16F77 to control the motors?

This person has a useful tutorial on a home-built PCB drill/mill:
