Yesterday I looked at the gang connector for the 1m.  I tightened the =
small screws that hold the front ring to the central portion that has =
the locking grooves.  Because they are small, they are easy to break and =
broken screws in delrin are hard to remove, so I tend to err on the =
light side when reassembling - there are plenty of examples of broken =
screws in the other ports and on the cartridges.
However, it did appear to me that the connector was fully seating in the =
1m port.  I'll look at it again when I have more time (Friday), to see =
if I can figure out why the feel is now different, but could I suggest =
that someone look at some data to determine if there really is a =
problem?
