Today I completed installing rib 3, installed numerous rivnuts for the various components including ground busses for the avionic & service (lights, pumps, etc) circuits, I need to source some rubber standoffs for these. Installed the original front skin again after having traced the door cut-out from the replacement skin which by the way is much thinner than the original. One door has been rolled to comply with the shape of the skin, I'll attempt to complete the other one tomorrow.
