I began the slow process of setting one rivet at a time, inspecting each one by mirror as I went. 43 done, kazillion to go. I left the SCAT in bay 5 for a while to make more room and only fed it through once the rivet line was forward of those lightening holes. Kinda tricky to do by yourself, but doable as long as you don't mind cuts, abrasions, bruises and a sore back :-)
