Rebuilt Action Touch is too light

[Farrell]

"What could I do to change the touch ."

Let me count the ways........ knuckle size, knuckle placement, flange friction, strike weight, whippen heel height, capstan placement, key ratio, key leading, etc., etc.

First thing to do is to characterize what you have. IMHO, the best way to start is to do a standard touchweight metrology evaluation - determine existing front weights, balance weights, friction, key ratio, action ratio, strike weight curve, etc. of sample notes. If you share that information with us you will get a lot of very good recommendations.

Without that info one will be shooting in the dark, IMHO.

Are you familiar with touchweight metrology publications by David Stanwood?

        Aloha , My local Piano teacher has another C-7 this one is older about 1967 that I replaced all the whippen assembly's(from Yamaha) , installed new key bushings, and new hammers prehung by Renner . She likes the action fast & light . One of the other teachers that works there hates it , and says a few of her students have a hard time playing it . What could I do to change the touch .

        Thanks , Brett
