Completed riveting the HS-411 assembly, cleco'd it back in the spar and enlaged mounting holes to #12. Marked all parts with relative locations to aid in re-assembly later. Began work on shaping the front spar HS-710 and 714 reinforcement angles. I did the first cut with a dremel cut-off wheel. Did not like the quality of the cut, so I bought a Craftsman 10 inch band saw. Sears did not stock the blade I wanted so ordered one on line.
