Hammer shank thinnning

[Chris Gregg]

Susan,

        I know that Bill Spurlock describes the shank thinning trimmer in
his handout on Grand Hammer installation.  The PTG Journal article is
November 1990 Page 23. There is a good diagram that accompanies the article.
He uses a laminate trimmer and a cradle that the hammer shank sits in on the
router table.  He only trims off the sides of the hammer shank.   Three
advantages with doing it this way. One is that wood can be removed evenly
from both sides, two, you have exact contol over the termination of the cuts
and three, once you have the jig made, the cutting is easy.
