Do you know any really good practical jokers?
I can't imagine a possible way for the chain to jump off the socket and
the key's unless they somehow broke would prohibit slipping elsewhere.

Hello all,
OK, I think I have a weird thing going here...
I have adjusted the wheel to center the turks head knot straight up
when the wheel is centered. I got it all nice & straight a few weeks
ago, and came back to the boat to find it about 20 degrees off to
port. By the way, were talking about 20% off on the wheel, not 20% of
rudder. After installing my autopilot, I again adjusted it, this
time getting the cables set to approximately the same amount of
adjustment on each side to the adjustment bolts through the radial
drive wheel. This required jumping the chain 1 or 2 notches on the
wheel sprocket.
All was well for a couple weeks, and behold, on Saturday I went back
only to find the turks head knot about 20 degrees to starboard.
During these adjustments, I have made a point to keep the cable
deflection adjusted to be relatively minimal (say 1/2" or so?),
without getting so tight as to reduce the feel of the wheel. I've
notice no issues whatsoever when we're out sailing.
During the first set of adjustments, I noticed the idler wheel bolts
were a little loose, and tightened those.
Considering the radial wheel bolts connect to each end of the cable,
and the cables attach to the chain, I can only think the chain is
somehow jumping on the sprocket.
Thoughts?
