Time now to install the seat backs. I didn't have any clamps that would work for this job (though I am thinking I will make some of the deep-reach cam clamps in the latest WoodenBoat magazine for future jobs like this), so I resorted to using screws. This worked pretty well,
though it left a bunch of screw holes to fill.
With the seat backs in place I cut and installed the little triangle transition pieces. The ones included with the kit didn't fit quite right, so I cut my own from scrap. Masking tape holds the part while the epoxy cures.
I then rounded the outer edge and filleted the inner curve and appliet a bit of fiberglass cloth. I like the way the cloth shifts to cover complex shapes like this without the need of cutting any darts or anything.
I saturated that with epoxy.
and put a piece on the inside, too.
And also took this opportunity to put fiberglass tape along the deck/cabin side joint.
Here's my first pass with the fairing mixture. It sagged a little on the vertical surface.
And here's after a bit of sanding. This still has a ways to go before I'm done.
I then turned my attention to the reinforcing rail on the seat back. I made this from two thin strips, so I was able to clamp them in place without steam bending.
I first laminated them in place on the seat back, but not glued to the seat back. After the epoxy cured I then took the lamination off and cleaned up the bottom edge, tapered it toward the rear end, and rounded over the bottom corner with the router. Then I took the result and glued it in place on the seat back.
I cut and fit the return on the front edge,
And trimmed the back to length.
A little bit of sanding finished it off.
I plan to install a cap on top of this about 1/2" thick. That will cover the exposed edge of the plywood and allow me to put a nice generous round over on to make it more comfortable to have an arm resting against. I may also add a wider section if I find that I like to sit up on the rail. I didn't know where the best place for that would be at this point, so that's a future item.
