  I've done quite a bit of this but...

  I'm off to a conference just now and then a business trip. I'll be =
back in about two weeks. If you've not gotten the information you need =
by then contact me privately and I'll see if I can help.

    Hello list,

    I am slowly getting ready to restore an old (1896 as it turns out) =
Bluthner 6'3'' grand.=20

    I will most probably float the soundboard in the deep base. I won't =
need to glue new ribs and there are none in the far corner that would =
interfere. I will probably also replace the board (and ribs) as it has =
collapsed and I am wondering just how long should this float (cut/rip) =
should be. What are the criteria involved in deciding on the length of =
the cut? How do factors such as thickness of the board, distance of bass =
bridge to rim come into play here?

    Another question I have been wondering about is whether anyone has =
ever floated the soundboard at the high treble end, along the short =
side, perpendicularly to the end of the bridge. What are the likely =
results of such an experiment. Btw the treble end float idea is just =
theoretical curiosity.

    Can someone with experience in this matter share a few thoughts ?

    Thanks,

    Peace,
