Hi Jack Et al, Have you or anyone else seen the key levelling system that utilizes a ong screw that goes down through the key button/key onto the back of he balance rail punching? Turning the screw in or out makes the key o up or down. I'd love to get a photograph of this for a class I'm eveloping: "Off Center Balance Rail Bearings" for PTG Institute 012 at Bellevue: Regards, David Stanwood David I have a customer with a Ludwig grand with this system. I sent a picture of that a couple of months ago. I don't have it any more, but I can take another pictrure the next time I tune this piano in April. I'll make a note in my data base to send you the picture.

French just before P. A. Starch bought them in the late 50s. When Starck was bought by J. P.Seeburg. in the mid 60s was when this system went into production. > It was indeed presented as the best leveling device ever, by the " Seeburg " brochure. > Its weakness was that after you leveled the key you then you often had to adjust the standard capstan.. > At first I really liked the idea. Then actually using them was not so good. > Of course the very best " leveling device" ever, was in the " Bowen Henderson" grand of Boston. It was a dream to work with. > Regards, Jack Wyatt Dallas, Chapter -------------- next part -------------- An HTML attachment was scrubbed...
