Lost my head

[John Ross]

Hi Alan,
At one of the conventions I was at, some instructor gave to the members of
the class, a simple jig, which made a neat repair.
It was a piece of wood about 1 1/2 X 1 1/2 X 4", it had a hole thru the
length that took the shank. A saw cut at an angle was cut through the hole.
The shank was put in and sawn through, then a hammer shank was put in, and
sawn. The result was two pieces of shank with fitting angles cut. There was
also a screw to hold the main part secure, then you just glued it together.
It comes out strong and neat looking.
My workshop is in kind of a disorganized state at the moment, or I would
take a picture and post it.
I hope my description makes sense.
Regards,
