[CAUT] Seiler Flexing

[wimblees at aol.com]

Hi Richard

I'm just speculating here, but I wonder if by putting the piano on the truck, the piano more or less bowed more in the middle because the legs are now "dangleling in mid air", if you get my meaning? Obviously it isn't a lot, but just enough to bend the sides of the rim just a hair, so that the music desk?slides in and out easier,,and for the?plate in the back to lower just a tad, which is allowing the string to touch?the plate.??

For now I don't think there needs to be a concern, but it might be worth?it to take a few measurements to see if there are any changes over a period of a year or so. One measurement would be the distance between the inside of the rims at the stretcher. (where the music desk sits). The other one is the distance between the string of Ab3 and the plate in the tail. BTW, why is just A3?touching, and not the others?

Wim?

Hi Jeff,
    Yes I do, and the piano has a DC with undercover for about three years.
It stays very stable.  The room RH was 33% last Thursday.  The piano was not
out of tune and there were only two unisons that were wild, one was D5 which
I've been having trouble with this last 6 weeks. The right string is always
quite a bit out of tune, this time it was flat.  I've been starting to see
if it is always flat or not but have not kept track long enough to know yet.
I've been paying special attention to that note when tuning, but it still
seems to be a problem.
Richard
