Spent some time prepping the skin, deburring the edges and setting all the clecos. I had an interesting challenge when I installed the aft spar for the ribs, where I was all alone and the pneumatic puller got jammed. It got locked onto the rivet and I wasn't able to complete the pull or get it loose. I ended up reaching the electric cord to tire up the puller until I could get some wire cutters. Once cut it was too short to pull anymore, so I cut the stem down flush, so I could drill it out and try again. The point here is that I ended up taking the puller apart and lubing up the jaws with the boelube and the result is that the puller is working better than ever.
A lot of clecoes to install
Ready to start rivetting
