[pianotech] Action Reconditioning/Rebuilding: When is it best to replace felts?

[William Truitt]

Another reason to replace action felts not yet mentioned - noise.  Old felts
compress, get hard, and noisy; particularly let off felts, back rail cloth,
front rail punchings.

Good call, Jon 

If one is to perform a full action retrofit, why stop at wips and
hammers/shanks/flanges....especially if the customer can afford it! I have
gone to the wurzen conical front rail punchings as well with nothing but
huge success and raves from the customers.  Like them a lot! 

Like when I re-string...new bridge pins and agraffes.... It only makes
sense.  OK, I admit, a few practice room grands didn't get
everything...sometimes, just new hammers, or new bass strings, but that's my
budget restraints!.....if only in a perfect world....

Replace all the key frame felts, including cardboard punchings.
I don't like to deal with dry-rotted punchings down the line.
Might as well replace the letoff buttons as well.

For the hammer rail, get a roll of fine emery cloth from Klingspor
and adhere a strip onto the rail with double-sided tape (a hardware
store will have 1/2" tape for plastic window sheets by 3M).
