Last time we saw the wooden tiller mockup strapped to the boat. This weekend was time to make the tiller stub attachment for the rudder cassette. It’s 2.5″ thick, so first up was five layers of 1/2″ foam.
It’s all carbon; an inner wrap of 12oz double bias, then four layers of 15oz unit on the sides, and last a other wrap of the db. The skinny end gets a 3rd db wrap – that’s where the actually tiller bears on it. Anton and Charlie saw how the previous one cracked on the little “strap” at the bottom end, so for this we added a U of 30ozs uni 1.5″ wide where the tiller will apply its downforce if someone falls on it (or just presses down too damn hard)
Quick side note – we bought some of the red strip Dacron peel ply that I see other builders using. It held up much better than the Econoply J nylon; took a lot more pulling to get it off but it didn’t tear apart into aggravating little pieces. Should have tried this stuff four years ago!
Next was making a paper pattern around the cassette for the big scoop cut, then trimming for the tiller and removing the foam core where the tiller bolts in.
That hole in the top becomes obvious on the next photos
On Sunday afternoon the cassette went back on the boat and a proper wood mockup was made up. Tonight in between Trick-or-Treaters we transferred that wood plan to foam core, and tomorrow night we’ll vac bag a layer of leftover 12ozDB from the tiller stub.
Since the original tiller got a bunch of work to get the hand-feel just right, and the extension stick mounted, we chopped off the good 18″ end to graft that to the new tiller. The shapes are different but a little creative glue gunning and foam shaping should make for a decent looking transition.
So far, so good on this project. Should be done and ready for sailing this weekend.
