Dwight, I do not know what Edison prefers or recommends but what I concentrated on is:
Enough tension to be sure the cables will not go slack under any conditions or rudder position. Not too much tension to place excess strain/wear on the other steering components. If there is excess play and the cables seem tight when tested center and at each lock I would inspect the rest of the steering system. IIRC I tightened the tensioning bolts, exercised the wheel back and forth, took up a little extra tension until the cable could be deflected 3/8 to ΒΌ inch (at center position). Calypso has chain moved by the wheel connected to the cables. It has been a while since I looked at the chain gear to steering wheel shaft set-up so I do not recall if it is machined out of one piece or if it is keyed (which could allow some play). Next time I am down at the boat I will climb under the cockpit and check the cables again to see if there has been any change after a few hour of sailing. I will give the cables another tension check to verify my estimated deflection.

Martin I would be interested to know how you decided that you had tensioned the steering cables enough. I have wiggled myself back to work on adjusting tension on my cables twice in the past month because after the first adjustment followed by a day sail I decided that I still had more play at the wheel than I wanted. After the second adjustment the play was less but I am wondering if more tension would be better. On my 35 MKII it is very difficult to reach the nuts on the starboard side cable adjustment at the quadrant so that cable may now be a bit looser that the port side cable. I believe I am correct in thinking that a proper adjustment requires the same tension on both cables and that tensioning one does not tension the other, but still if I wiggle back there far enough again and manage to adjust the starboard side I would like to know how tight the cables should be.

I removed the rudder for some repair this July and had the quadrant out to clean and inspect. After 43 years it looked good as new. I use the flat underside to match up with the top of Calypso's autopilot tiller arm. The two are bolted together for mutual support and a doubling to the shaft/key surface. As other posters stated, the fit to the rudder shaft and the woodruff key are very important. If in doubt about the fit, replace the key. Once had one shear while sailing a C&C 39 off the northern California coast. Made for an entertaining morning. On Calypso I did pay close attention to how well the steering cables lined up in the grooves. After my first install there was a slight interference at full lock. I invested another 90 minutes in moving the quadrant 1/4" up to make sure the cables were properly lined up.

So far 2 down, one up, we should run a betting pool and I will be speaking with EDSON, whose sketches are a bit sketchy and who don't make a point of saying. Will let you guys know. The rebuilt rudder is back in...just the motor and steering controls and we have a boat....
