After ripping down a board into the right widths using a table saw, I had to trim them from 5/8" thick to 1/2". To keep the boards tight against the fence and top, I used a couple of fingerboards. They keep pressure on the board but allow it to smoothly feed through.
Since the boards were only 10' long, and the gunwales are about 16' long I had to scarf pieces together. This is the pieces set up for cutting a 9 to 1 scarf with the block plane. It took about 15 minutes, but I neglected to get a pic of the completed scarfs. I then did the same thing for the deck carlins.
Weights come in handy for gluing. Trying to keep 20' of wood aligned while using clamps across a 4.5" glue line is not easy. However, laying them on a flat surface allows the use of a 48" metal ruler for alignment and allows for sliding the lower scarf into place. Since epoxy doesn't need much clamping pressure. I got good results with this method.
After gluing I checked the fit of the gunwales and made sure I had enough clamps. Then I did some final shaping with the block plane to round over the bottom edge and taper it toward the bow and stern. Gluing took quite a while. First I had to wet everything out with un-thickened epoxy, (64' worth). Then I had to spread thickened epoxy (32') and then get everything clamped up. After that I had to clean up and fillet the squeeze-out. That took a couple of hours. As you can see below, you can always find a use for lots of clamps. I used every single one I had, and it seemed to be just enough. I'm sure If I had another 5 I would have found a use for them as well.
