Tom, Thanks for the reply but I have the thinnest balance rail punchings sold by Schaff and their are no glides on the keyframe. Sounds like the other thing to do is have the keys too high in relation to the keyslip. Any other ideas?

I must jack up the the back rail felt to fit properly with the keyslip. Then I find I don't have enough movement in the key to get enough key dip. Any ideas? Thanks Ray Ray Breakall Piano Technician University of Richmond Richmond, VA (804)287-6342 Ray, Sounds like the balance rail punchings are too high. Check key frame for integrity, check for proper bedding (someone may have lowered the glides excessively.) and perhaps start over with all new keybed material to match the case etc. Also jacking up the backrail will change damper timing and that could turn this job into an all day event ! Good luck, Tom Driscoll
