Today was all about drilling the starboard rear fuselage. Essentially this was a repeat of the bottom skin drilling process. Because the side skins are so much wider than the bottom skin when laid flat, I temporarily widened one end of my forward 2X5 work table by clamping scrap boards to the edge. This provided a way to spread out the forward ends of the 2X2 square beams that are the real base that everything sits on. For additional clearance and access to the underside/outside when positioning stiffeners, I added cross supports to raise the skins above the beams. Got both the longerons and the stiffeners drilled. Ready to disassemble and debur/corrosion protect. Nothing especially trickly about this process. Just pay attention to hole size on the plans.

Room to manuver under the supports and in the open spaces between the table and beams.
