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)?

I took the handle off a tap wrench and then pressed a 3/8 socket on
the end. Then I use a speed wrench for the handle. Holds the tap nice
and square. I can't remeber *ever* breaking a tap with this, haven't
went 0-80 but i wouldn't be afraid to have you try it VBG

One of those offset handle things? That's REALLY scary.

But if I could find a way to fit to my little 3.6V Hitachi DB30L (hex
shank drive)... it might be okay. It has a clutch, rocker reverse and
is light enough that there could be enough 'feel'.

Thanks, off to the drawing board (well, CAD package).
