"Throwing" the shanks revealed contact that pressing the shanks into the rests did not. There was a good 5mm of surplus thread, so I had Jeremy remove all 88 screws, reduce them by 3mm on the grinder, and re-point them on the sander for easy threading. We left the buttons in place, so I was able to continue with the action while the screws were being shortened. There is now ample clearance, with the option of peeling the rests, if needs be. Thanks Newton!

Peeling is not uncommon but you only need a little clearance for proper function. Peeling could cause the shank to hit the screw because the hammer could come off the string at near one hundred miles an hour. Most likely about 50 mph but give yourself a little safety margin there. If one screw is a problem try screwing it deeper into the button or you can nip off the top a bit or saw off some at the other end. When they get it wrong we have to make it so. Newton
