One trick is to braze a drill bit of the correct diameter to a length (12"
??) of "music wire." (Groove the dull end of the bit so the wire comes out
centered and adjust with a hammer.) Guide the bit with heavy gloves or a
bit of tube slipped over the wire. Works well for small bits. Haven't
tried anything larger than 1/4".

I saw at the Miami boat show a salesman demonstrating an adaptor that
when attached to the drill you could adjust the angle of the drive more
than just a 90 degree fitting. (Should have bought it) I need to drill
into the coaming through heavy glass and tap into a metal backing plate
and the bottom holes clearance is less that 1 1/2" above the deck. Any
suggestions out there??

Thanks, Chris
