We started out with a nice chunk of ash.
We cut it down to size and drew out a very simple pattern.
We jigsawed out the rough shape, and finished it up with some rasping and tons of sanding. ASH IS HARD. And heavy. With the thwarts, seats, and yoke, our featherlight canoe is not so feather light.
We set them aside for a while and started work on the seat. It's made from the same piece of ash. We sawed them into 1 1/2", drilled, screwed and varethaned them. Below we set them in place to get an idea of how they would fit and look.
While we waited for the varethane to dry, we began to fit the thwarts. We drew the profile of the gunwale on them and cut them down on the band saw. Then we used the palm sander to make them fit to the camber of the gunwales. Then we disassembled and varethaned them. They were then drilled and attached with 1 1/2" stainless screws, predrilling and countersinking each one. Note that you really have to predrill the ash, as we broke off two screws! Luckily we were able to unscrew the broken parts.
