Alternate suggestions for methods of drilling itty bitty holes will also

Harbor Freight has an little air tool Item # 47869 that has the high
rpm's for drilling small holes. Somewhere on the internet there is a
web site showing how some kids made a drilling machine for PBC's that
used one of these to drill. The machine drilled from the bottom up.
A laser pointer mounted above showed where the hole would be.
