Homebrew PCBs

When running, the drill bit should not look like a dog wagging its tail.

I'm not sure about the others, but those of us on other lists who do a lot of precision drilling have found the Dremel to be useless - unless you want a lot of broken bits.  It just has too much runout - I measured mine at over .005".  I have found Foredom handpieces to be quite acceptable.  An old Unimat would also do a good job.  The Foredome will cost well over £200.  Unimat's have become a bit of a collectors item and cost more than when they were new.
