It was an exciting day for me. My recently purchased 1907 Ivers Pond upright got it first tuning and a new agraffe. While the piano tech went back to his shop to get the right piano wire he let me adjust the lost motion and bend back the damper strings (Installing the new agraffe necessitated replacing two piano wires). As part of the process three dampers were replaced and several were adjusted.

In preparation I did a pitch raise a couple weeks ago. I'm absolutely delighted with the results. It has a sweet sound and the action is much more responsive.

It is an old piano and there is still a lot of improvements to be made. I still have my Acrosonic when working on the Ivers Pond, but it doesn't compare to the rich tones of the much larger Ivers... Many thanks to those on the Tech Forum who have offered advice and guidance.

- Rick

I've said before, the two uprights I wouldn't mind rebuilding are the K-52 and the I&P.

I think you're going to be pleased with the end product.

And, is that a compensator or a sostenuto action in the bottom right of the picture? Action looks fairly straight, there are some back checks that have their own ideas of where vertical is…

Looks great, Rick, and I'll bet it sounds great too!

I love the old, tall uprights...

Sounds like your project is coming along just fine! smile

Based on my limited experience, it seems that not many makers used the agraffes on upright pianos. The Petrof upright I had had the agraffes. Also, I saw an old Story & Clark upright with the agraffes. And, I think Steinway uses them on their uprights.

Thanks for the update.

Rick

IIRC, the agraffe was broken and had to be replaced, necessitating the string replacement.

It operates in conjunction with the soft pedal to compensate for loss motion. At least that is my novice interpretation.


I have question, I read the section in Reblitz on letoff. Of the several things remaining to do on the regulation, one is adjusting the letoff The butt buckskins are rather worn. None of notes are double playing at this point, but the letoff is significantly more than 1/8". How does that affect the piano?

Thanks,

- Rick

The let-off can be set to a consistent distance,even with worn butts. You will want to check your aftertouch after you do this. The affect let-off has is to determine how closely to the string do you remain in control of the hammer. You have to "throw" the hammer though the dead space which is let-off, and the greater it is, the harder it is to judge how much force is required to play a note, softly.

I rarely replace wires when an agraffe is broken, it is better for the piano to use the original wire, but it takes a particular technique to do that. Any journeyman tech should be able to do this, but maybe that isn't taught any more.
Regards,
