Started to roll the leading edge of the rudder; i used the eye bolt method which seemed to work very well; regular ductape was not working very well; I recommend Gorilla tape for this task, this is wonderful stuff and will not tare. spending extra time on this proceedure will give you a nice radius and fit together nicely.after this was done i used the edge forming tool to put a small bend in the edge of the top skin to create a flush fit, be careful not to over bend the lip. riveted the leading edge together, fit was pretty good.
