W11-03 Wing Attach Blocks - Pollished all sides to remove any cut or machine marks. Aligned W11-03 with W11-05 End Attach Angle and drilled the remaining 3/16th holes. W11-02 End Wing Attach Assembly - For one of the assemblies I used the drill press and drilled and updrilled the 1/4th holes for the two AN4-15A bolts.
