Hammer types

[Clark Panaccione]

Hello,
Thankyou for writing these observations of hammer
sounds. This is kind of opposite because it depends if
their sound was already acceptable, but I found it
illustrative to extend David Stanwood's chart with
three lower groupings, that you can see with some
examples in the right hand Excel chart
http://www.freewebs.com/mireut/strain.gif ; the
different weights and materials (the "l" in the legend
means leather, "f" felt) look like they are connected
with wire strength and tension seen in the other
graphs, as well as how they act together on the sound
board ("s" square, "u" upright, "g" grand) that might
be suggested just by calculating loads due to
deflection, shown approximated for 1.5 degrees in the
few secondary drawings
