Create two wooden spacer blocks about an inch in length. Insert the spacer blocks into the ends of the F-1 041-L Lower Fuselage Channel. Clamp the forward end of the channel into a vise and the aft end with a crescent wrench. After double checking the twist direction, use the crescent wrench to twist the Iower fuselage channel to match the dimensions. Repeat this step to modify the F-1041-R Lower Fuselage Channel. The right channel is a mirror of the left.
After double checking the twist direction, use the same method as Step 1 to twist the F-1040-L Upper Fuselage Channel to match the dimensions given in Figure 3. Repeal this step to modify the F-1040-R Upper Fuselage Channel. The right upper fuselage channel is a mirror of the left.
