Terry, I am coming in late on this but am wondering if, in addition to the 52mm length (good choice), you have also checked to see if whatever passes for a capo is actually linear, without bends, curves and/or deflections toward what would be the keybed as you move upward from the tenor to the top treble? If things are truly as screwy as they seem to be, you might need to try to work out the plate height from whatever you can reconstruct of the proper regulation of the action. I think I would set some samples throughout the action, and then set the plate height using sample "strings" (maybe 12 or 11.5, something light enough to not cause problems, but sufficiently heavy to not deflect too much while measuring). Someone used to make/sell large flat head machine screws with allen sockets that were great for this kind of thing. The screws would (sort of) self-thread into the holes for the perimeter plate screws, then the plate was set on top of them, and the allen key could be used to adjust the height of the plate. Quite inventive, and a real time saver. Traditionally, for S&S, the plate height (for the treble) was measured at note 62 (with the assumption that the capo was quite straight). I cannot speak for how other makers do this. Best. Horace At 10:37 PM 2/3/01 -0600, you wrote: > >Anyone have any input on whether I should go with a 52 mm or a 47 mm > >speaking length?
