Spehro,

The sanity, or lack thereof, is more likely associated with runout and hand
shake of cordless drill.

Looking at using some relatively small screws tapped into (probably)
6061 aluminum. Through holes, maybe 0.08" of material. Is it insanity
to think about using a cordless hand drill and run them right through
without backing off (assuming a good quality coated tap and aluminum
cutting fluid)?
