  Friends:

  Here's the deal -- a 10-year-old Renner action in need of some work.  =
All of the hammershanks in the killer octave section go decidedly to the =
right (non-perpendicular to rail) rather than squarely over the =
whippens.  This is the only section that is affected, and this =
"hammershank detour" is almost enough to cause the hammer to miss the =
left string when the note is played.  Each flange is "anchored" in back =
by a pin in the flange rail in addition to being held in place by the =
flange screw.  In other words, side-to-side movement is kept to a bare =
minimum.  There is no room in the size of the screw hole to allow for =
proper alignment. =20

  Does anyone out there have an economical means of dealing with this?  =
Sure I could pull out the anchoring pins, but what would be the best way =
to keep the flanges from drifting around?  Would laying down a thin =
sheet of sandpaper be an option or would the thickness of the sandpaper =
alter the action spread?

Remove the hammershanks. Pull the pins. Install sandpaper strip. Replace =
and space the hammershanks.
