<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hi Avery I just had a couple Steinways with exactly the same symptoms. I would suggest you make sure the screws that hold the cross strut in place are dead on tight before tightening the bell. We just went through all about what that is for, and even printed out the origional patent on it. Just a month or so ago. Quickly tho... it functions as a device to add mass to the plate, and hopefully make that area of the plate less susceptible to vibration, with the effect that sustain is somewhat preserved (for not to say increased). The patent makes other claims, but Dels explanation seemed quite convincing. I think one wants to be kind of carefull tightening such bolts, as it is not unthinkable to put too much pressure on the plate. You are also increasing downbearing at the so called killer octave.

Can someone tell me what the 4-sided (older instruments) nut is just above the highest plate strut? The newer ones are 6-sided. I had a buzz the other day that I could stop by touching the plate and I finally stopped it by tightening that nut. It's been a while since I've had a plate out and I can't remember what that attaches to. Why would that cause a buzz? Thanks. Avery  </blockquote> -- Richard Brekne RPT, N.P.T.F.
