Hexagonal Shanks

[Joe And Penny Goss]

Hi Jim,
Yes we have wandered as usual <G>
I think that we are all thinking of a different idea or consept in relation
to the topic.
What I was musing about was that the shape of the shank when round must be
heavier than that of a shank that has a hex or ( added ) octagon shape added
to it's form. The shape will afford IMO the nearly the same strength as the
round but be lighter. Whither this is any advantage to a piano hammer shank
in the tone that is achieved is debatable as differences in the wood itself
will certainly
be different from shank to shank. The wood differences will also affect any
testing you do. It might be better to use a different material like iron and
infer the results to wood.
Must go rake leaves, Honey do<G>
