Maybe off topic, but I also bought the drill stand from Proxon, and along with head lenses this works fine for my hand - drilling. If I'm going to make an effort to make drilling easier, my next stepp will be a CNC drilling machine. They are fairly easy to build, realtively cheap in the end and - well, do it very prcisely.
