Spent some time making lower longeron clamps. These take the triangular shape and make them into a square for clamping. A difficult job then becomes easy.

Carefully cut the lower longerons so they are easier to bend when they go on the sides. Plans have just the rear cuts, I also made a few incisions in the front section so that the timber will have less ‘tension’ in it when fitted.
