Wesley, As Dean mentioned, first raise the balance rail supports and make sure they are not lifting the action too much. Then, hopefully, the front rail will not be so high off the keybed at the center. You can plane / sand the ends to fit. If there is still too much height in the middle, one good repair is to glue some veneer to the front edge of the keyframe on the bottom, then sand / plane everything to fit the keybed properly. Reset the balance rail supports after the front and back rails are well fitted. Another technique is to cut saw kerfs across the front rail if there are not any yet. This depends on the rail type and stiffness, but some front - to - back kerfs on the bottom will make the rail more flexible, and could help it stay flat. There are more possibilities, but I think these are the most common ways to treat unusual front rail bedding. At the end you will likely need to reset key height and dip, at least a little. Don Mannino _____ From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Wesley Hardman Sent: Monday, February 25, 2008 5:49 PM To: Pianotech List Subject: Wurlitzer G411 A customer of mine has a Wurlitzer G411 in which there is approximately .090 inch of clearance in the middle between the front rail of the keyframe and the keybed. The space decreases from the middle to each of the ends of the keyframe. What is the best way to solve this problem without sanding an enormous amount of wood from each end of the keyframe?
