I thought that had corrected the problem.
They just told me yesterday, that they couldn't use the unacorda during the performance.
Embarrassing or what.
I swear, when I left the building, there was no squeak, but there was no one there to show. So it is possible they don't believe me.
When I turned the right side glide bolt up by 1/8 to a 1/4 of a turn, the squeak did disappear. It also disappeared for one push of the pedal, when I put some Teflon on the contact point.
I think Roger's suggestion, of the action being too tight at the dags, fits the bill.
Mind you, I don't know if they would let me try, after my first failure.
I did tell them, that since I didn't get it fixed, I didn't feel I should charge.
I asked them for the serial number, so I can contact, Webb, so we shall see if I get a reply to my e-mail.
Oh did I say, that by lifting very slightly, on the left side of the action, the squeak disappeared, and that is what led me to the glide bolt?
It didn't seem loose when I turned it, it wasn't tight either, I used a 4" crescent.

  John-
  I have experienced what you describe.  I have often found the offending glide bolts to be somewhat loose... sometimes enough so to allow being turned by hand, but any movement at all can translate into squeak, though I don't know why. Even if not that loose, you can feel the friction by holding  the glide stem lightly, as you shift the action. I try to correct any loose glides by glue sizing.  I'm wondering though...if what you did corrected the problem, why isn't that the solution?  Am I misunderstanding something?

    Hi List,
    I was wondering if any of you have run/ran into this problem.
    It was a S & S model B, less than 6 months old. It is the first time I have seen it, and I got a call yesterday afternoon, wondering if I would have a look at a squeak problem, before a concert this afternoon.
    So I went this morning, (extra charge of course).
    I thought it would be an easy fix. But, noooooo.
    I checked all the obvious places, regraphiting any worn areas, tefloned and MPL'd appropriate spots.
    Still there.
    Tried pushing shift lever by hand, still there.
    Not the spring on the right side, that bears on the action.
    Tried moving the action toward me, a smidgen, no squeak.
    Couldn't find anything wrong at the dags.
    Then I tried lifting the action at the right side just a smidgeon, gone again.
    I turned the glide bolt back 1/8 to 1/4 of a turn, most of it gone, but still some at the other end, but very slight, turned left glide bolt up less than 1/8 turn.
    Squeak gone.
    Not enough time before concert to get into it more fully.
    Have any of you ran into this causing a squeak?
    Is there a proper fix, that I should go back and do?
    Thank you.
