    I'm working on an older Yamaha G5 - ca. 1962 - which lacks glide bolts. I forget what the optimum approach is to bedding this kind of key frame. Suggested procedure? Thanks!

    Pat,

    I have an early 70's Bosendorfer with the same issue. Never got any resolution on it. Interested in if anyone else does.

    Aren't there wedges on the front rail to flex the frame?
