Just one
more example of the numbers alone not telling the whole story. =
Some
years back I compared maple hammershanks to hornbeam shanks =
directly,
although the tests were not exhaustive. On average, the maple =
shanks
had less bend to them. I did not find that the hornbeam shanks =
"transmitted energy" any better than did maple shanks -- =
if as
well. The repetition lever stop screw (sometimes incorrectly =
called
the "hammer drop" screw) became loose in the flange much =
more
quickly in the hornbeam than in the maple. Hornbeam forks =
(where the
centerpin goes through) was also more susceptible to impact =
damage.
The maple shanks were simply "tougher."
<P>There was a greater variation among the maple shanks, =
however. In
fact, I suspected that some of the maple shanks I tested were =
actually made
of soft maple, not hard maple as specified. The manufacturer =
of the
maple shanks was not generally noted for its careful quality control =
procedures.
