Thanks, Art - my US shopping list now includes Bullet drills *and* long

The general problem of keeping all the holes in a line along the boom is
that even a 1deg error will show, because there are all the other
elements to compare against. On say a 2in diameter boom, a 1deg error is
only 20 mils around the diameter.
