Hammer Boring Jigs

[Paul]

Bill
I think the PTJ had an article on boring jigs a few years ago. Can't
remember the issue number. But anyway, I combined some of the features of
them and made one out of UHMW plastic. The jig holds the hammer molding's
center axis on its rotating center axis.This allows me to bore at any angle
and have the center line of the shank pass through the center axis of the
hammer-very fast and accurate to drill the "sweep" from the tenor up to the
treble. all other settings are adjustable too. I couldn't find all of the
features I wanted in any one jig.
