Installed reinforcing angles on bottom of center boot cowl section (glareshield). Fabricated these out of .020 angle and affixed with VHB tape. These greatly stiffened up glareshield and will eliminate any oil canning as well as providing a stable surface for the G5 GPS antenna. Final riveted the visor, center boot cowl and left boot cowl sections. Next, I'll glue the vinyl glareshield cover to the center section, then install the avionics cooling fan and GPS antenna. With the right boot cowl section still off, it gives access to the underside of the boot cowl. Finally, I'll rivet the upper right boot cowl section and glue the right side of the vinyl down. Huge step today to final rivet the boot cowl sections. Onward and upward.
