Today started off with removing half of the clecos I had holding the skin on. After what seemed liked forever, I got to start drilling. Once done with that, move the clecos over 1 hole, drill again. Jason one of my employees told me, this plane doesn’t ever get finished, you just keep moving clecos. It sure feels like that. Once I got done match drilling, Jason & I marked off each hole that is not to be dimpled. Next after disassembling the entire I structured, I began the process of scotchbriting everything. Once done with that, I used my new Cleveland Aircraft Tools Sub-Structure dies and dimpled the substructure as required. Are these necessary, I don’t know, but they worked just fine. I also noticed that on the skin I have a slight bulge where the middle rib was. It doesn’t appear to be too bad.
