Replacing the keypins. The brass tool with wooden handle grabs the base of the old pin and extracts it without enlarging the hole. Here, the front rail pins have been removed and I’m working on the balance rail pins.

Keyframe before and after

Old and new capstans. The green tarnish on the brass is evident, as is the rough surface. The anodized aluminum is also lighter.

New key end felts being installed. The new capstans are visible at the top of the image.

Rebushed keys being reinstalled.  The new balance rail pins are about .002″ larger than the originals, so the balance holes in the keys have to be carefully eased for a tight but free fit. The key leads have also been removed and the holes filled. Later the keys will be weighed off with new leads to match the new hammers.

Rebuilding the pedal lyre – replacing pedal pivot bushings

WP_20170317_08_53_11_Rich

Not much left of the original cloth bushings – that for the sustain pedal has been completely abraded away

WP_20170317_09_00_44_Rich

Pedal pivot rod has been polished and the cloth bushings replaced with current NY factory nylon bushing sleeves and new leather spacing washers.

New “Raviolis” The rear of the pedals land on these bumpers

Old and new pitmans (pitmen? This part connects the sustain pedal trapwork through the keybed to the damper action inside the action cavity) The original badly tarnished brass pitman system often exhibits excess friction at the cloth bushing through the keybed – see the “white” cloth bushing at the lower left. The ends have left deep impressions in the heavy leather pads on the trap lever below and the damper tray above (not shown).

WP_20170319_09_14_42_Rich

In the new Steinway system the cloth bushing through the keybed is eliminated and the ends of the pitman are captured in holes in the damper tray and sustain trap lever. Friction is reduced to zero, and with it any chance of a future pedal squeak developing here!
