Jerry, I believe H&L build replacement tillers for just about any boat, and have in stock or patterns for any one design.
I sent them a pattern of my own, and of course more radical than any they show on their web site.
Thought they would find a close match to a set up they already had. But I got back was a beautiful and exact laminated tiller of the pattern I sent, rounded and sanded for about 70 bucks.
There are no glue lines in what they do, so I suppose they use 'plastic resin' glue
the mix with water powered stuff. Traditional for glue up spruce spars, imco. It's water resistant. But you hardly ever see one of their varnished tillers delaminating. Except down at the tillerhead where the bolts are and people forget to juice the holes through the wood.
