Hi all, I wonder if this is not similar to what happens when you wish to tighten a hammer with a wooden shank. Even though there is lots of friction, tapping the base of the handle works (and quite brilliantly). I also wonder if there is a force to one direction on the duplex bars so that when oridinary vibration of low frequency but large amplitude from a moving van allows them to shift. Do they tend to go out of tune in the *same* direction? Or has anyone noticed that happening. I wonder too, that if after they were tuned a drop of thin CA glue (or perhaps one of the anerobric glues) might not hold them in place, yet still allow them to be moved later if necessary (a sharp tap would break the glue bond) Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T.
