The second day of our class with the Plantation camp kids was yesterday but here are a few more pictures of some progress. I will post the final shot with them and the boat all set up tomorrow.
The above pictures show two frames, part way finished that will go into the boat. The plywood corners, or gussets, are glued and screwed to the douglas fir frame pieces. In the 17th century the corners of the frames would incorporate a naturally grown crook, or curved timber, perhaps from a trunk of the tree and a branch, or root. Oddly enough that sort of timber is hard to come by these days so we use this modern method of straight douglas fir pieces connected with plywood corners. The plywood is strong because of its multiple plys running in different directions from each other. As mentioned, the gussets are attached with glue and screws, a system boatbuilders like to call the old “Belt and suspenders” method. Each one would work for the job, but in case of a potentially embarrassing failure the other is there to take up the slack.
Speaking of embarrassing failures, we did manage to resteam and rebend two pieces of oak for the stems. I will show the finished products tomorrow in the shot with all the kids but here’s a picture of the jig we built to bend the oak around.
The brown paper has the shape of each stem drawn on it. the dimensions were scaled directly off the plan. The blocks are pieces of 2×4’s some of which had to be slightly shaped to fit on the curve of the stem. the blocks are screwed from the back of the plywood. No glue was used. We thought it was worth the risk.
