Whoa!  That might be it!
Not someone messing with me - I've been having the teak refinished, and the 
wheel had been removed for that work and was laying on the cabin top.  So, I 
could have easily put it on the "wrong" side out.
If that's it, I can breath much easier!
That could also account for the first time it was "off" after initial 
adjustment...

I'll still need to check for rust on the plate, but that gives me immediate 
breathing room.
If you're right, I owe another $50 to Stu! Bruce Whitmore

If I take the wheel off and rotate it 180 degrees, does that create the same 
deviation?  I routinely change between my 32 inch (cruising) and 36 inch 
(racing) wheels.  If I don't put the wheel on with the correct side forward, it 
is always off a spoke or so. 
Could someone be messing with you?

The turks head wraps across a spoke, so no, it can't be moved.

Subject: Re: Stus-List Edson wheel chain jumping links?    And weirdly, the 
steering is very precise, with no sloppiness underway, and it happens when 
we're OFF the boat!    On a side note, when we leave the boat, I tie off the 
wheel just in case there is more current than the wheel brake can control.  
This is done to keep the wheel from turning to the stops, and to prevent wheel 
brake wear. Our slip is in shallow water, and though we have never noticed the 
rudder touching bottom when we sleep on the boat, the keel stub will touch 
during low tides.  Thankfully, we have a soft sand bottom.    Maybe the boat 
settles at low tide or a current comes by, pushes the rudder against the line 
ties, causes slack in the chain/wire rope, causing the chain to jump?  I have 
not tried to look at how slack the cable becomes when I hit the rudder stop.    
The rust, however will have to be dealt with sooner rather than later...    Any 
further thoughts would be appreciated.   Bruce Whitmore

assure you that there is rust.  What I can't explain is why the problem comes 
and goes and at such a prescribed amount.  The detrimental rust would also 
likely cause a looseness in the wheel and cables which would be quite 
perceptible.    Josh          On Jan 24, 2018 11:12 AM, "Bruce Whitmore via

was slipping on the rudder post it could cause that issue.
Maybe use a sharpie and put a line down the rudder post and onto the radial 
wheel.
20º is not much movement, you may require a fine line.

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?
