The store room is getting a bit full! Have also (mostly) decided on a tiller only boat and purchased 2 6' sections of 1.5" pipe schedule 160. Also happened upon this nice rudder head. A very common style that seems to be very hard to find now.
There may be one more new one at a store in Jacksonville and will check next week. otherwise I'm sure one will turn up. Otherwise can get one machined up near the launch if need be. could make one myself if I had a lathe. Maybe a project for NZ if the first tuesday in November indicates an additional trip is necessary.
Also note the 2" tube material tht just fits over the 1 7/8" OD pipe. Quite easy to find a set of 2" delrin bushing for 2" rudders,but very hard to find 2" heavy wall tube? Anyway, makes for a perfect fit in the rudder head.
