I have actually tried the plier-squeeze method on an old upright piano, and was surprised at the difference it made, and how well the piano sounded afterward. But I'm still a little scared to try the plier-squeeze on my better pianos, but may get the courage to try it at some point. You don't hear much about the plier-squeeze method, but if the hammers are really hard, it could be a good method to use.
That seems like a crude form of the sugar-coating technique, at least as I understand the latter.

At my last tuning, the tech wanted to address all 4 of the hammers needing voicing by filing the hammers. Two of them were well addressed in this way. One of the others has a note that tends toward a more percussive attack than its neighbors. It needs voicing about every other tuning to keep that in check. The sugar-coating technique has been effective in that regard in the past, and I'm thinking I may purchase a sugar-coating tool, and do it myself. Diluted fabric softener might be a permanent solution, but I'm leery of trying it as it is hard to start minimally and increase while testing the effect.

The 4th hammer just needs voicing down. I ask the tech if voicing needles would be needed, questioning whether a filing would achieve the objective, and he said that in his experience filing is all that is ever needed for any voicing issue. That's not what other techs have indicated to me, and the hammer still needs to be voiced down after the servicing.

It seems like what I am asking for is pretty basic and should be in the repertoire of any RPT. Certainly, they are charging at a level consistent with a full service, and not at a level of just a basic tuning.

If the only tool you own is a hammer, everything looks like a nail.

Mr. Turano came here from Muncie this evening and was surprised to find that my 1869 piano was not a complete wreck. What he did:
sanded three or four hammers to mate them with uneven strings
needled several hammers to reduce brightness
found the keybed needed to be inserted at a slight angle to keep the extreme treble hammers from hanging up and still let A0 repeat -- thought somebody had put the wrong (new) pin in the bass end of the keybed
found a dead-sounding bass string had been twisted twice and sounded better when twisted only once

So I don't need a new pinblock or restringing. The piano sounds a lot better.

That is great, Ed!

I once twisted a tubby sounding bass string in the wrong direction, and found out in a hurry I needed to twist it the other way (although I thought I was twisting in the direction of the coils). So, I can see where two twists might be detrimental where one might be just right.

Sounds like you're back on track without a total rebuild! smile

Iā€™m glad my recommendation of Brian Turano worked out for you and your piano, both Brian and his brother Michael worked for me at BU while in their final year at NBSS, they were there at NBSS I think 2 years apart.

I should also mention that the reason the piano wasn't holding tune was that the strings weren't rendering when I tuned it. Didn't bang it hard enough. Mr. Turano demonstrated the technique of pounding on the keys without regard to musical intervals in order to make the strings move.

what would happen if you apply pure vinegar in the felt?

It wouldn't taste good. Add Oil, Salt, Pepper.

Not kitchen vinegar, the pure vinegar doesn't smell after 10 minutes, it's as volatile as isopropyl alcohol...

The vinegar is a glue solvent and the felt will be released from the molding.

What do you mean by pure vinegar? Glacial acetic acid? That's certainly volatile but I wouldn't put it anywhere near a piano.

you could put the hammers resting horizontal and soak only the edges with pure (distilled, or maybe white) vinegar. I never tried, just wondering if that was a good thing.
