Hi Ron: Good to see you back in the land of the living. One must always do the damper alignment with the damper rod in place so that you know that all the dampers are lifting evenly. The damper wire bending is most easily done before the hammers and shanks go in. Of course one must check end samples of the hammer stroke and damper lift timing to avoid unnecessarily large adjustments of the damper spoons later. What I like to do after all the hammers are glued in is to use a caul which is of rectangular shape 5/8" by 11/16" by the length of the shortest distance between action brackets. This caul can be wedged in between the hammers and the strings at the strike point so that as one raised a wippen by its backcheck, one can see if the damper is just barely tickled by the spoon as the hammer hits the 11/16" spacer caul. Once one has learned how to fit the spoon regulator tool to the spoons (this is the hard part) one canadjust the spoons to pick up earlier or later as the test indicates by merely bending the spoon our farther to the back to pick up earlier, or by bending the spoon closer to the wippen rail to make the damper lift later. There is another method which has been written on in detail which you can find in the archives if finding the spoons with the tool is problematical. This involves setting spoons at the beginning and ending of each section in the piano and then, on the bench, aligning the rest to the samples. Good luck.
