I installed the angles that attach the rib 9# support channels to the wing aft skins today. As per instructions given by many other builders (going against the plans here) this is done from the inside. The channels were first installed in the rib, then the rib was put in place and then the angles are clamped in place and drilled from the inside. This ensures no bumps or dimples in the wing skins. It's a bitof a lengthy process as you have to remove the aft skin to drill the forward skin, then re-install the aft skin, remove the forward skn and then drill the aft skin. When all this was done I updrilled all the holes to #30, took rib #9 back off, disassembled everything and prepared the belcrank and support channel parts for priming.
