[CAUT] Steinway D cross strut buzz

[Porritt, David]

Ric:

I've done this on a B that had that buzz.  Yes, you can remove that
strut especially if it isn't wedged in there by tension.  I think it's
even OK to remove it to replace dampers without having to bend wires
getting them past that strut.

Hi folks.

We have a troublesome Steinway D which develops from time to time a very
annoying, for not to say downright obnoxious, buzz that activates when
one play C6 loudly. Thats the only note that will get it going... but
boy does it ever.  I have isolated the problem to the cross strut where
it screws into the middle cast strut. (farthest distal) I've been able
to tighten this before and alleviate the problem but this time around I
actually had to loosen the screw just a tad.  I have no doubt that in
some period of time things will settle in again and the buzz will
return.

I am 99.8276 % sure that if I was to put a small piece of thin bushing
cloth between the cross strut flanges and their counterparts on the cast
plate that the problem would go away once and for all.

My question is... dare I remove the cross strut even for a short time to
do this ??

Thanks for any input
