Below is a sequencing of making new frames for this boat. I am using some old growth douglas fir and West System Epoxy. On these at the present time the two outer layers have 2" kevlar between them and the inner 3 layers have glass. My first intention with this first one (last photo) was to subsequently add the 20 degree bevel. As 20 degrees with it's thickness wouldn't bend, I first cut a couple of 10 degree wedges. These were also too thick. Next, 6.667 degrees. Better but once epoxied up and trying to bend into the jig, slipped all over the place even being taped together. Subsequent ribs are being made full size and bevels will be cut after the fact.
The sticks are hot glued to the plywood and than moved to the work table. As the temperature dropped, I realized I made a mistake with making this 8' x 12' table with two layers of 3/4" plywood top and 6 5x5 legs... I should have made it across the road in the single car garage which is much easier to heat? This 30' x 48' with 1/2 the walls insulated and roof just trussed isn't quite ready for heat. Though it does have radiant floor heating plumbed into the concrete slap, no heat source has been hooked up. Too many projects, too little time and finite resources!
