Grand Piano Restoration: Keyboard Set-up

 The key frame at this point had the old felts removed and has been fitted with the replacement felts measured for correct size against the original. The key frame is then fitted into the cavity of the instrument and checked for warping against the key bed and shimmed if necessary. 

Once the key set is completely restored with new bushing felt, new buckskin back checks, damper lifter felts, and the capstans polished, the key set is ready to be returned to the key frame and set up with the correct geometry using felt and paper punching to lift or lower the key set.

Here are some photos of that process being completed.
