[CAUT] Hammer Alignment

[Jon Page]

Is it just me or am I crazy but I've noticed a misalignment
of hammers after a year or two.  By this I mean that the
hammer has leaned towards the treble such that it requires
re-setting.  Angled too much for burn-in.

Could it be that the shanks develop a twist, warping
in a clockwise rotation as viewed from the front?
Gravitation whiplash from the rotation of the earth?

The travel is not the culprit. When installed, they were dead on.
I've noticed this developing more so on Renner shanks than Abel.
It's disconcerting to find your laborious efforts gone astray.

They're not bored off center. I can't recall ever finding
ones that leaned counter-clockwise.  Oddly enough,
the bass doesn't seem to exhibit this phenomenon.

A newish M needs most of the top two treble sections reset.
Yesterday I reset at least a dozen on an L which had new h/s/f
three years ago.

One could past it off as a poorly hung set
but I know that was not the case.
