We also put fabric in the forward compartment, and on the bottom 3 planks for the entire length. After the fabric was wet we coated the entire inside with two coats of epoxy, and then sanded it in the area of the bulkheads and frames.
Rogers friend David came for a visit, and got pressed into service as we glued in the bulkheads and frames. We applied a heavy mix of epoxy and cab-o-sil to the edge of the frames, then lowered them into place. We became quite good at making nice even filet of epoxy along the edges with the end and side of a wooden posicle stick.
We used a web strap as a clamp around the hull and pulling down on the top end of the frames to force them into the hull. Here we have all the frames in, fileted and waiting for the epoxy to cure
When the epoxy was cured we coated the entire inside of the hull for its final coat.
Next we bent on the rub rails. This was very easy, the bend is gentle and the strips are quite flexible. It did take every clamp I had, plus some of Rogers and David's.
We cut some strips of scrap to put on the inside of the hull so we didn't have to put a block under each clamp.
I didn't get a photo of the second layer of the rub rail, but it went on just as easy.
After the rails we did considerable sanding on the inside of the hull. I wanted to do all the possible machine sanding in the area of the seats so we wouldn't have to get into so many corners. Here we have the aft seat in place and are putting a filet around the edges. The paint cans are for weight to be sure the seat stays down and doesn't slide around.
The forward seat had to be trimmed just a bit to fit in. I think the seats were the only parts in the entire boat that required any trimming, every other piece was a perfect machine cut.
Here is a close up of the filets around the seat edges. We are now very good at making nice filets that minimize sanding.
