Thanks Rodger

Julia,

My understanding is that the rest rail needs to sit squarely on all of its supports, so that it doesn't warp.  That's the reason that the una corda pedal in uprights needs a hair of lost motion, so that the rail isn't propped up only at one end.  Typically there are three or four felts that the rail sits on; I suggest adding spacers to each one.  Cardboard front punchings work well.

  Greetings,

              Thanks for the suggestion on manipulating the hammer rest rail. I put a washer as a spacer behind the action bracket in the way right treble. Boy did that clear up the treble closeness, it seemed to help throughout the rest of the rail too.

              Also, upon closer examination, I pulled on the rail, and there was negative lost motion. I put some lost motion in a few of the keys and kept track of the degree of turn, then I went through and turned down all the capstans by 3/4 of a turn and the blow distance is now much more consistent; within 1/32" of the selected 1 3/4" 

  Thanks again,
  Julia Gottshall,
  Reading, PA
