I wasn’t ready to tackle the stiffeners so I jumped ahead and decided to fab the tie down brackets. Cut each to length and then tapped the bottom holes for the tie down rings. I then match drilled them to their respective spars and CSK’d the nutplates rivet holes. I then Sanchemed and primed both brackets. After the primer was dry, I riveted on the nutplates. Starting to really get back into building mode.
