The tape holds the tool onto a carriage, with holes which slide on the 
rods. Front foot feed. The base slot is used to align the drilling angle 
with the pin row however you like it, for such niceties as avoiding 
intersecting pins in the bridge body. It's as simple, idiot resistant, 
and quick to build as I could make it. Even has a depth stop. I chose 
the Black & Decker because it's a full 2 amp, where everything else I 
found was 1.2 amp. I can run it slow enough to not generate clouds of 
smoke, and still have enough torque to put a #36 drill into my epoxy 
laminated cap and rock maple root. I really like it. So far so good.

Looks real good here now, whatever caused it. ???
