I have a Camelopard endpin (a hollow titanium endpin filled with a dampener) designed and built 25 years ago and no longer available. I have used it on different basses and somehow it makes a big difference in the open resonance of my bass. It is 5/8 tube and came with a beautifully hand made and gold filled fitting/plug. The rub is that it does not perfectly fit in the hole at the bottom such that when it is under pressure it pulls out a little and slightly unseats (maybe a 1/4 inch) Gael used some shims when installing it and it has worked that way for some time (slightly unseated) but I don't like it. Is there any way to refit plug and hole so that the fit is tight and does not pull out? thanks.
