Noah,
with the action being held on a cradle.  Tilt the action so the backchecks are as close to parallel to the bench as you can get them so you don't get any liquid run off in the action.  Try using white vinegar on the old felts.  After you apply a healthy amount to each they will just lift off.  The vinegar stinks, but it works!

  Subject: backchecks


  i want to replace just the center section backchecks of an old Steinway during a partial regulation. I noticed i can buy backcheck felt. i wonder: could i get the ild felt off and glue the new on without compromising the wippen pinning? 
  or should i just remove the backchecks anf replace them with the block, and if so, with or without a new wire? what's the easiest way to remove? thnx for any replies.
