It seems I tried to outsmart myself when I switched the rod to the other side of the table by just trying the goalie rod. I just switched the two-man rods and, viola, the 2-rod that had been binding now doesn't. The rod that had been smooth now binds, but very slightly compared to what the other rod did. Very strange. Methinks either Anderson is right, it could be the far wall bearing, or Alaskan Thunder is right that I need to re-level the table. If/when I figure this problem out I'll share the information on this forum. Whatever is happening on my table is bound to occur again on some other table.
Old Meister, where can I find tin-oxide?
