Re: Progress on Leeboard Pivots

Updates... It's been a while...
Post #8 in this thread shows some braces inside the hull designed to back the "fins" that support the leeboards away from the hull when they are lowered and doing their job. They were 3/4" ply, about 3" wide x 9" tall, with a radius on top. There were 4 on each side.

3 looked like they were rotted 3/4 ply, and needed replaced. I thought, fine. Got those 3 off, and 2 more looked suspect. Yeup, they needed replaced too. So all 8 came off. Good thing, as there was rot I couldn't see under 2 others!

What a pain to get those out! Repacements went from chine log to shear clamp, 3" x 1", white oak, (everyone of those suckers measured differently!), epoxied all mating surfaces. And sucked in place top and bottom with screws through the hull. Once done, I then sanded down the equivalent outside surface, and added fiberglass seam cloth in epoxy where the fins would be supported. This whole mess ate up about 40+ hours of my Christmastime boatwork binge.

Before, brace removed, note where rot was coming in around bolt hole




And another location, did I say, lots of room to work? No?




After, all 1 x 3 white oak, all epoxied.




Outside of hull, after fiberglass tape is added, but before final fairing and primer

Re: Progress on Leeboard Pivots

Okay, now for the finished mounts:

All white oak, epoxied and screwed together, with white oak plugs, epoxy finish, then several layers of poly. Note sil-bronze bushings epoxied into bores. Size overall: 6" x 8-1/2" x 3-1/2". Note also, slope in base inward, to drain water off the rear deck of the mount.








Now with kingpins installed: all naval bronze, screwed together w/ weld for extra strength, thrust washers as well as a stopper flat behind the nut, and 18-8 nuts. Should work well.

Re: Progress on Leeboard Pivots

BTW, holes nearest the kingpins go into the shear clamp via lag bolts, the ones on the back ears of the sides go through the decks, with fender washers added to the hardware below! And for those holes, since the deck was only 3/8", I added full-width partners between the frames, of 3/4 ext ply. All coated in West 6-10 epoxy.

Also, comparison between my final design (left) and the original:



Also, leeboard straps on either side will be 2" x .080" naval brass. Originals were 1-1/2" x 1/16".

Estimated time on all of these, less design and procurement:
wood mounts, 40 hours
king pins, 30 to 40 hours
inside hull bracing replacement, 40 to 50 hours
glass-taping outside of hull, 10 hours

Doesn't look like that much time, does it?

The original design in mock-up:



I think my deign is far superior in style, strength, and in spreading the load out across a reinforced deck area. My biggest fear is banging upside a dock with these things!

Re: Progress on Leeboard Pivots

They are a work of art. I had a leeboard on my Naples Sabot (just 8 feet long). I added another so it would point a bit better on the other tack too. It is all a learning curve.
Sorry about the trailer thing. "Trust, yet verify" is my motto after having the same type of experience many years ago. "Oh sure, my ex-wife has the papers and I'll get them to you next week."
kind regards,

Re: Progress on Leeboard Pivots

Well, it's been a while... Got some serious work done over the holidays and after. Mainly working on finishing the assembly of the leeboard support wings, fairing their mating surface to the hull, finish shaping and fairing, and a couple base coats of primer.

Leeboard assemblies:
Ready for priming:





Primed:





Test-fit:







Leeboard mounts:
