Finished setting up and building the first of two -12 compression ribs. Much slower to build up these ribs as many of the pieces have to be trimmed to size by sanding carefully, including the nose ribs. Much more use of the power tools that I'm stll learning to use. I used a Bondo squeegee to spread the coating of T88 on the inner sides of the sheeting to seal them up. Much quicker than the popscicle stick method used on a single sheet rib earlier.
