Yes Mike, this works. It was described somewhere in the Journal in th=
e 80's
(I think Suzan Graham had written this tip). The way the spade birt w=
orks
you have to understand. The bit will cut from the shank side (you hav=
e to
make a cutting edge on the OPPOSITE side of the tip of the bit). Then=
 you
insert the bit with the shank pointing down and protruding from under=
 the
keybed. Then you attach the drill to the bit and drill PULLING from u=
nder
(kind of reverse drilling).

  I don't think this will work.  You will need to get a right angle d=
rill
attachment to fit between the pinblock and the keybed.  I've done thi=
s
before and I had to get a forsner bit and cut the shank off to a nub,=
 and it
was still tight.
