No doubt one of many! Cutting the Hoop Pine top frame for the transom was a disaster. I had left the jigsaw in "pendulum mode" and the blade twisted badly creating a terribly skewed cut. I cut it off straight and glued on a 20mm piece of pine, so all is well!
I never throw out wedge-shaped bits of offcut wood. Wedges come in handy quite often :) here I'm using then to square up the claps on the curved surface of the transom stiffener.
