Starting the splits
Working the ends
Bending with hot water
My first attempt resulted in a cracked stem piece, but luckily I had prepared an extra bit of stock in anticipation of some mistakes. The next two stems didn't crack and were held in place in a jig I made with scrap pine board and some nails.
Broken attempt; 2 stem pieces drying on form
Once the items were dry a few days later and after most of the gunwale lashing was complete, I clamped the pieces into place and began stitching them into place.
Temporarily clamped; Hull inverted; Stitching into place
Once these were in place, I spent some more tedious time stitching the lap joints, gores, and any other minor cracks that appeared in the boat. For 2 large knotholes in the hull, I ended up stitching extra pieces from the inside that I'll end up gumming up tightly when the time comes.
The completed bark hull
Even though canoe looks hogged at the moment, this is apparently normal after it comes off the building bed. There's a lot of "flex" in the bark at the centre of the canoe, so it'll pop into proper shape when the ribs are in.
