Lakeracer,

Did you use plywood for your frame mockups?

The frames are completed. 3/4" Doug Fir with 1/4" plywood on both sides instead of gussets.
A small weight penalty, but I have 400+ hp to push it. 8)

Got a little further on. Fairing done on chines and first layer of bottom planking fitted. I need to get some white oak for the sheers. Doug fir even steamed would not take the bend at the back by the transom ( 4 laminations ).

For those that have done a double planked bottom how did you attack the first layer to the chines, battens, keel, etc. ? Did you screw and glue everything down and then remove the screws to screw and glue down the second layer or some other method?

Great progress on the boat !

    On the first layer, we pulled the temporary screws after the epoxy had cured. We also recessed the chine to accept the first bottom layer.

    Fitting the port second bottom. We used steel screws with the same thread pitch as the silicon bronze screws.
    Once all the screws were driven in, they were removed one by one and replaced with silcon bronze screws.

Thanks Mr. Hot Rod,

That is similar to what I envisioned. : )

What type of steel screws did you specifically use that had the same thread pitch?
I already have a pile of those small plywood squares already. LOL

Your getting there now keep up the good work. When you are doing the side planking make sure you use the best bit of ply near the transom, check it for any voids or knots or anything that might give way under severe strain. "I learn from my mistakes " :D
