Making the shape of the rudder leading edge using bender. It took quite awhile to do the shaping and lot of strength. The bent leading edge was then match with the line drawn on the plywood. The 3 1/4 x 0.032 tubing was placed on the line drawn & the rudder leading edge was then put in place. Perfect match.
The top end of the vertical tube for the rudder was hammered into shape to fit in the leading edge top end.
