Just did it on my Pearson
35. Turned out to be way more expensive than I anticipated largely because of slight bend, uneven diameter, and out of round rudder
shaft. Used thick walled aluminum
bronze tubing as a sleeve over the rudder shaft and for the shaft extension. Wasted a bunch of expensive machine shop time to get a no slop fit of the sleeve on the rudder shaft. Had to go back to machine shop at least 5 times to get a no slop fit of the sleeve to the rudder shaft. Despite religiously searching ebay and Craig's List for 5 years never turned up a suitable tiller head. All the heads required a larger diameter shaft than mine. Rethinking it, could have bored the sleeve to a larger diameter for the extension shaft that the tiller head bolted to. In any case, went with the Edson
tiller head which is a beautiful but very expensive piece of bronze.
Long story short, came to more than $1500 to convert to tiller. Tiller head was $500, Aluminum
Bronze tube and extension shaft, $300. Tiller $150. Rest of the money
went to machine work on sleeve, shaft extension and UHMW cockpit
fitting. Best money
I've spent on the boat.
