Here`s a couple of shots of the shearwebs. They have certainly stiffened the wing, although not probably critical with the planned OS 10 FSR installation. I packed all round the spar in the first bay with 3/32 sheet; the other bays got 1/16" placed vertical.

I am conscious of trying to keep the weight down. As shown here the assembly weighs 7 5/8 ozs
