<blockquote type=cite class=cite cite>OK all you engineer types. I
was repining some hammer flanges today on a Steinway that has been in a
practice room. Action parts are Renner. It gets hard play 14+
hours a day. The action was rebuilt 4 years ago. Nearly all
of the bushings were quite tight -- most 1 or 2 swings. A few had 3
swings and I was pinning for 4 so since the action had been in the shop
(idle) for a couple of weeks, I thought maybe I could just vigorously
work the shank a few seconds and it would swing 4. I'd hold the
flange and make the hammer swing back and forth fairly forcefully for 5
or 6 seconds and then test it again. In each case the ones that
previously would give 3 good swings, now only gave 1. The hammer
dropped from horizontal to vertical and stopped dead. <br>

What made the bushings get tighter by simply working the flange?
I'm stumped!<br>
