The photo above is the aft pedestal in one of Jason Cajune's boats.
My next task of choice, not necessarily in the right order was to make a decision how to construct the aft knee brace. I like the idea of the flow through interior. I want to be able to get from the bow to the transom without crawling over a knee brace. I've decided to do a knee brace similar to the one that Jason Cajune does in his "Recurve" boat. The problem is, it ain't easy by any means. The one I'm constructing will look something like the photo above. I first thought they were a little too "George Jetson" for my taste. But as I've explored my options I've decided the Jetson's were cool.. There aren't any plans or instructions how to do this so I'll have to just dead reckon my way through it. I'm pretty good at that.
(a) Figure out how to construct the darn thing.
(b) Figure out how to attach it
(c) Decide if it's permanent or removable
(d) Get it done or figured out before I paint the floors and the lower part of the sides and dry boxes.
Solving the Construction of the Aft Knee Brace
The knee brace is constructed by laminating 3 layers of 3mm Okoume plywood in what amounts to sort of a "Question Mark" shape. Pretty appropriate when you have no idea what you're doing. It will end up about 7/16" thick and glued together with thickened epoxy. I started out by cutting some different shapes out of scrap plywood to see what shape seemed "right".
Here's a photo of one of the "Question Mark"s I cut out to see what it might look like. This one was too deep of a bend I thought. I cut different shapes until I got one that seemed right. For me it's just sort of a trial thing. Try different curves until I thought "That's it". I'm shooting for a height of 27" above the aft level floor.
Once I determined the shape, I needed to construct a form to bend the plywood to the desired shape. I laid out the "Question Mark" on a 1/2" sheet of plywood and made to opposing pieces that will mate together with a 7/16" gap between them (the thickness of the laminated plywood). In the photo above you can see the 7/16" strip that is being cut out. I had to make two each in order to make a form that was approximately 24" wide.
Here's the forms assembled. I will be bending 3 pieces of plywood that are 24" wide by 48" long. All I have to do now is figure out how to get the 1/8" Okoume plywood to bend to the shape. Another "Question".
