How many clecoes?..... all of them. I had to borrow a few. I built one work bench 10’ long, and that worked out fine. Once I had the skeletal structure completed, I made two jigs that held the wings vertical, nose down right next to each other. I was able to get on either side. I had help riveting (back riveting, actually) the top skins on.
