#1354823 - 01/21/10 01:28 PM pressure bar height

Hello All, I am restringing a 1970 Steinway Z 45" upright. The original height of the pressure bar seems excessively low. In addition the v-bar was badly gouged in some places (perhaps from excessive string pressure?) and these notes had an unpleasant metallic zinging noise that disappeared if the strings were spaced out of the grooves. My customary approach would be to duplicate the original height. However, this piano has many other unusual factory original features; I don't want to duplicate a previous error. Given the problem the piano had before and comparatively excessive bearing, what is the best way to calculate an appropriate pressure bar height that will provide adequate speaking length termination and appropriate friction?

Thank you, any input would be appreciated.

-Nathan Cook

You may use a thicker felt in that case.

If the angle was too tight it should not be a problem to lower it, after reshaping the bar as possible (I use a little parrafin on it afterthat)

may be the problem is not the bar but the capo.

Del Fandrich could certainly give you an angle, I'd guess around 20° but unsure.
