I recently worked on a roughly 100 year old Pleyel grand in of all places,(where else but)the French Ambassador's residence here in Washington DC.Somewhere along the line it has been restrung and and partially rebuilt.The problem is that the front rail only contacts the key bed on the ends.In the middle it is bounceing up and down causeing power loss and letoff and after touch proplems unless you play pretty hard.There are no adjustable glide bolts either on the key frame or the bed.Sanding the front rail seems like a long and possibly futile method.I seem to recall a method of cutting a saw curf in the front rail to help lower the rise in the middle.Is this done from the top of the rail,or bottom,or both.Do you shim and glue or just leave an open slit in the front rail.I look forward to the lists opinions and experience in this.
