I'm afraid reducing the cheek block thickness can present its own complications. The only other recomendation I can think of is to reduce the thickness of the key frame stop block, which means you will have to shift the hammers and maybe the wippens. That will give you more travel. By the way most of the techs I know adjust the shift so the left edge of the hammer just touches the left string not completely missing it. The idea being subtle changes in flavor rather than gross changes. David Koelzer Vintage Pianos DFW ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
