I've followed your instructions. The points were slightly worn so I tidied them up a bit and tightened the truss rod slightly (it was quite loose). This seems to have worked (I've just tuned it and despite needing to reset the intonation everything seems in tune :D ) yet for some reason, if I depress the bar far enough, the right side of the bridge seems to slip off the post by a few millimetres, then returns (still in tune may I add) to its original position. Is this supposed to happen or have I done something really bad? :confused:
