This entry logs my work on the lower section of the rudder frame. To accomplish this I shaped the upper surface of the rudder control horn using the scotchbrite wheel. This will allow the horn allow to fit in between the rudder spar and the lower rudder rib. Noting the improvement that the scotchbrite wheel did to the upper portion of the control horn, I went ahead and rounded all of the corners and edges of the control horn with the scotchbrite wheel. After that,I fit the lower rudder frame together.
