I didn't notice any difference in the repetition.

As for removing hammer mass, this should be more related to tone and voicing issues


I strongly agree with this, I would consider reducing hammer mass as an last resort since it does have an affect on the tone and future voicing. However, I see nothing wrong with it if both the technician and the clients are happy with the result. I may have a lot of preferences, but at the end of the day, I'm servicing the piano for my client's satisfaction..

Asb37,

Have you actually looked at your damper regulation as Rick suggested?

Thank you for all the replies. There is a lot of good information here.

The strike weight of F3 is ~9.75g. This isn't super heavy, so I'd be hesitant to take too much weight off the hammers. However, I will say that this piano is very loud and somewhat harsh for my taste - so if lightening the hammers reduced the volume and softened the tone, that would be a favorable change. I'm tempted to try taking 1/2g off to see what that does to the touch and tone.

I believe the action ratio is around 5.85 right now, but I need to take more careful measurements. I may be able to reduce it a little further by cutting the balance rail punchings a little farther back from the balance rail pin. Otherwise, I'd have to move the capstans or knuckles.

The damper regulation is pretty good from what I can tell. I've had a couple of technicians inspect the regulation and they both said that everything looked OK, but obviously some small things could be improved. Since then I've regulated the let off closer to the strings, set the drop to about 1/16 in, and set hammer blow/key dip/aftertouch to get a dip of about 13/32 with 1mm aftertouch. It's not perfect but I think it's in the ballpark. The jack tenders were also recently regulated to the correct position relative to the knuckles.

I am going to make some detailed measurements of action leverage, DW, UW, front weight, and strike weight this weekend. I'll post the results and see where to go from there.

Thanks again!
