Rudder and steering system back together today, couple of hiccups but all worked out in the end. Thickened epoxy cured over night, now I have a base that is square to the rudder shaft and the top collar that holds the rudder in place was also turned on a lathe to be perfectly square to the shaft. Radial drive installed and steering cables attached and tensioned. The rudder feels amazing, 200% smoother than before and I have no rudder play.
