Slow Hammer Return

[Ron Boyd]

Is there a chance that the piano is not level? I know this can cause
problems with the hammers returning if the piano is leaning towards the back
to much.
John Ross mentioned the hammer rail springs corroding off. I just finished
replacing all the springs on a 50’s vintage Everett. I found from asking
other PTG members that the felt was the culprit so I scraped the felt off
and sanded the rail so it was clean of any felt.

Some actions had a problem with hammer rail springs corroding off, but I
think that was the '70's.

“If you are sure” is something I can’t be sure of yet in this new endeavor.

Other than the slow return of the hammers, everything is functioning
normally.  The notes still play, they’re just losing energy because they can
’t get back to the rest rail.

Are there any other causes I should look for before I try soaking?

Thanks very much!

If you are sure it is the hammer butt/flange action centers that are slow,
on a piano like this, I recommend removing action and soak action centers
with about a 50/50 mix of alcohol and water. Let dry overnight - do not blow
dry with heat. 90% of the time this will free up all the action centers.

Lots about this in the archives.
