It would seem to me that if you have a case of the rotated hammer flange rail... an easy fix would be to run an extra layer of felt along the distal edge of the rail thereby re-angling the hammer flanges. I'd imagine you could go as much as 2-3 mm without getting into too much trouble depending on the exact situation. If its not a rotated rail... well back to the drawing board. Cheers RicB (ahem), Steinway offers a variety of parts,and there have been stock parts sent me that certainly did not fit. The jack/hammerflange contact is not unheard of. Your problem is more likely in the rails than the parts. If the hammerflange rail is just slightly rotated, there is interference. The pin to pin distance may be correct, but the flange will be out of place. Ususally when this happens, the drop screws are turned all the way up. If no new parts are available, you can often stop the problem by removing the proximal half of the jack, near the top. Regards, Ed De'Foote
