With help from my son (and kean flyer) Alex, I managed to get the floor stiffeners started and clecoed up each end. He was just the right height to stand underneath while I marked where the rivet holes were to go. Back at it after a short break, I finished drilling all the holes for the floor stiffeners. I deburred and countersunk all 4 stiffeners ready for corrosion proof and prime. Thought I might keep going and do the soldering iron trick on the bottom skin along the rivet lines on the outside and I will prime the whole skin on the inside.
