Today I worked on finishing off filing the relief holes on the HS-702 Forward Spar. Finished off filing and sanding down the rough edges on the HS-702 Horizontal Stab Forward Spar.
I also made sure that the flanges on the inner section of the HS-702 were sufficiently flattend. To assure that the work was done correctly, I sent pictures to Vans Technical Advisers to check the relief angle from the hole ot the edge of the spar
I then began fluting the Horizontal Stab's Ribs. Most of the ribs had only a slight bend, so it did not take much to properly flute them, But having never fluted an aluminum part before I had to do a bit research on line about what is a correct flute and how the part must look when fluting was completed.
After completing the fluting of all the ribs, I then spent some time smoothing out all edges and removing the burs on the Horizontal Stab ribs with the scotch brite wheel and sand paper.
