I use a Minicraft drill and stand, similar to the Dremel units. It isn't
very good - it's quite easy to break carbide drills. A friend of mine has a
PCB dept. where he works and they have a rather old manual Excellon PCB
drill. It looks as if it was originally ∗very∗ expensive and is ∗very∗
heavy. The drill comes up from underneath the PCB and a magnified image of
the pad is shown on a screen. Someone at Southampton University was giving
one of these away a few months ago, perhaps I should have taken it off his
hands. 8-)
