Installing the Back Rail Felt

Glue a strip of back rail felt onto the back rail. If your strip is not wide enough to span between the rear edges of the pins and the rear edge of the keyframe, butt the front edge of the strip up against the back of the pins – it’s not necessary to have the entire back rail covered with felt. In any case, apply glue only to the rear ½” [12.7mm] of felt. The front of the felt is not glued – this helps to quiet the key when it drops down onto the felt.

The keyframe is now complete.
