Hi Kim,
I'm looking at pulling the rudder and replacing the rudderstock on my Heritage 1 ton this spring. Mine has an aluminum rudderstock that has corroded beyond what I'm comfortable with. The shaft is schedule 80 pipe (1/2" thick wall rather than solid).
I'm considering opening up the rudder, putting in a new rudderstock, and closing it up again. Also looking at a new bearing set as part of the project. Working on the replacement rudderstock design. Not yet sure about a hollow vs a solid shaft (which many Heritage 1 tonners have). I have access to titanium pipe and may go that route. The schedule 80 aluminum one has lasted 30 years or so.
If you'd be willing to share how your rebuild went, I'd appreciate gaining some wisdom from you experience.
Tom
