Per Randy "I always install a 1/2" wide piece of capstrip in front of the spar between the legs of the nose block (also make the gussets bigger) on the compression ribs only. I like to have something solid between the drag wire blocks so they will pull against themselves and not just the glue line. .... Another place I install 1/2" cap strip is on each side of the spar on the lower spar butt rib because so much of it has to be removed to get the rib over the spar butt plywood and strap fittings. "
