Cleaned and prepped fuselage side skins. Trimmed stringers. Clecoed in place. Marked middle longeron for trimming. Riveted tailwheel steering cable pulley mounts to S9 before riveting bulkheads. Be sure to do this prior to riveting S9, S10 to bottom skin or you won't be able to get rivet gun in afterwards. I had already match drilled the rear portion of these mounts to S9.
