The topside battens are fitted and installed with 3M5200. I had them soak for several days so they would conform to the hull shape. The top batten (called shear stake?) soaked for 6 full days, and I still needed to use clamps as weights to make the necessary twist.
Screwed and "glued" in, showing the barrel stern.
I'll let the 5200 cure for a full 7 days. 3M5200 cures with the humidity, and it has been very dry for several weeks. The on to topside planking and routing. But first, selecting the right wood to use, with regards to grain, color and pattern.
