Thanks, Ryan, this is very helpful. I've been on the phone to a string maker, too. Duh, it hadn't occurred to me that I would need to measure the whole string scale, because I haven't done this before. I'm glad to know this <before> I write the estimate. :-) Hmm, I wonder how heavy that brass weight was... Less bad is what we're after. Actually, I think it's the tuning instability that bugs my customer most. A DC system is being considered, too. Thanks again.

I suggested she hire Del Fandrich to take a look at it. Del found that the tension on the last 4 notes really dropped. I think it got as low as around 80 pounds of tension. If I'm remembering correctly we put in 4 bichords. (8 strings total). We used the same agraffs, utilizing the two outside holes. We were able to keep the trichord wedges for the Damper felt. Del did ad at least one hitch pin. Lastly he installed a pretty hefty brass weight to the underside of the bridge. All in all it worked out pretty well. As Del said all along the goal was to make it "less bad" and it was certainly successful in that regard. The client went from being constantly distracted by the lowest tenor notes to being able to enjoy playing again. So don't give the client too high of an expectation! -- Ryan Sowers, RPT Puget Sound Chapter Olympia, WA www.pianova.net -------------- next part -------------- An HTML attachment was scrubbed...
