Multipurpose Mini-Machine for your Workshop

These days everyone is talking about how great 3D printing is but for the hobbyist this still limits you to plastic parts. Before 3D printers were around I always wanted a lathe and a milling machine, I still do!

When you want to build more than just basic robots it is sometimes necessary to make small metal parts. Maybe you need a special metal rod, mounting bracket, shaft adaptor etc.

PCB CNC Drill

So this is the basic idea, more so I don't forget but any input/comments always welcome.

Create a mini CNC for drilling PCB's, it would require...

Building an X/Y Table similar to Geir's (sorry can't link, using a Tab). Instead of a pump hook up a 12v motor with a drill bit adapter

Mount the motor so it can move on the Z axis, either on a spring with a servo to push it down, or threaded rod like normal CNC mechanics. Use the handy TIP120 for switching on/off. (2.2K resistor, Diode)
