There is a kit for tangential CNC-Drilling machine.
check www.radixgmbh.de , was a ELEKTOR project, driver and program should all be there
check out www.elektor.de (you understand german ?) no, go for .uk search for "TanBo"

There are several design guides 'out there' for this.  I looked in to it a
while ago to see if I could build a automatic PCB drill machine:

My favorite:
http://freeandeasy.sourceforge.net/

"We have built a prototype XY table, but due to its complexity and the
requirement for expensive slideways and ballscrews, we have rejected the XY
table in favour of a design for a rotary table we came up with which has a
much simpler mechanical construction (though the maths is harder!). Click
here for more details and an interactive simulation, and here for pictures
and movies of our prototype rotary table in action."

Do a Google search for this "pcb drill hpgl home" you find others.
Search for "cnc home"  or "cnc hpgl" etc. turns up a few as well.
