Re: Tahoe 23 project, Norway

Fasteners are a big investment. I am using SB because of corrosion concerns, with the exception of the carriage bolts between frames and motor stringers (a significant savings and easily inspected). So far, I have been able to find five screws with router bit and saw. In that respect, I much prefer ...

Hi Linda and Bruce,

It is nice to hear of another Michigan boat builder and the Riviera is a cool boat.

Re: Main stringers

Hi Steve, I used African mahogany on my Tahoe 23 and the material list recommended "mahog, fir". The rough sawn lumber I used was a full 2"x10"x16'. After planing, and straightening, I just managed a 1 1/2"x5 1/2"x 16'. Next time I will laminate two layers of hard wood ...

Re: Michigan Squirt Build

Jim,

I don't think I would use 5200 for any of that. The stuff is really sticky, expensive, and sandable solid when cured. I really like 5200, but only for those thing you never, ever, plan to remove. I think 4200 might be a better choice...

Re: Tom's Tahoe

Thanks.

Pete, you caught me! There are four little pieces to finish out the blocking at the lower edge of the plywood. I left them out to give myself a little access for encapsulation. They will go in with the second coat.

Re: Tom's Tahoe

I could not resist the urge to force a piece of 3mm plywood into the scallop.

The little voices in my head say "attach it now" and "you'll regret it if you do".

Re: Tom's Tahoe

The blocking to define the scallop shape has been installed and faired on the transom. Transom 170824 3.JPG The battens flanking the scallop have also been cut. I sprung battens across the transom to match the camber of the deck and then cut the bottom of the notches, screwed the battens down, and t...

Re: Tahoe 23 project, Norway

PeteG is correct about Van Dam using solid lumber to cold mold. They use alaskan yellow cedar for the inside layer and then switch to marine plywood for the intermediate layers. It makes for a beautiful interior.

I agree the hardware looks great. Wonder where it came from.

Re: Tom's Tahoe

Toivo, The initial plan to cut the step into the area above the rudder has been abandoned. The plans show a transom made from a layer of plywood with blocking aft to create a cambered transom. I am keeping the plywood and doing something different aft. The area from chine to keel to chine is extende...

Re: Epoxy bonding issues with white oak.

The short answer is sand with 80 grit, thoroughly wipe with 70% alcohol with water, and lightly clamp. The Gougeon Brothers at West Systems do a lot of research. They tested white oak samples using different joint prep methods. I couldn't find the that study. They published a few other articles, htt...

Re: Laminating frames

The lamination would work well. You might also think about turning the lamination so the individual pieces would be narrow and then stacked to make the wide dimension of the frame member.
