I finished the elevator stiffeners by sanding them and then polishing them with the scotch brite wheel. I then started clecoing them to the elevator skins to find out that I cut the E720D,E&F stiffeners too short. Looking at the plans, it looked like I was supposed to trim them a little short. A closer look at the plans reveals that I was only supposed to cut the taper a little deeper. Oh, well, place another order for $6 worth of parts with $5 worth of shipping.The construction will be stalled because I have no more parts to work on while I am waiting for the rudder rib to arrive. Oh Well.
