Depending on where the Hamilton = was, the hammer butt buckskin where the jack contacts the hammer butt = becomes worn after many years of playing. If the regulation is set to = specs without repairing that buckskin, there is an indentation in the = buckskin that the jack can not escape and that causes the "bouncing" = action. That is the reason the in can't be regulated properly. Look at = the buckskin of a new hammer butt and compare it to the hammer butts in = your Hamilton, you will see the wear. OR if a butt or two didn't have = the jacks centered on the buckskin, you can see the ridge left on one = side or the other and then you can compare how much wear is visible.
