29-11, Steps 1, 2, 3, 4, & 5
Using the dimensions given in Figure 1, draw the "Start of Roll Line" and the "End of Roll Line" on the F-1069-R Forward Side Skin. Repeat this step for the F-1 069-L Forward Side Skin.
Clamp the F-1069-R Forward Side Skin to a table, using the Clamping Block. Align the "Start of Radius" with the "Start of Roll Line" . Be sure to align the "Start of Radius" not the edge of the block with the "Start of Roll Line". Double check that you are about to bend the forward side skin in the correct direction, the outboard face of the skin should be down against the table with the inboard face up. Align the flange edges of the F-1070A and B Roll Construction Angles with the "End of Roll Line" on the F-1069-R Forward Side Skin, then clamp them in place.
Roll the F-1069-R Forward Side Skin into a cone that terminates in a sharp bend at the aft end of the "Roll Lines". The roll is created with the forward vice grip, and the sharp bend is naturally formed at the aft end. Twist the F-1070A and B Roll Construction Angles with the forward vise grip and at the same time push the forward end down and inwards towards the table. Use the extra roll construction angle which extends forward of the vise grip as a handle for your other hand. The twisting and pushing motion must be balanced. Twisting too much will create a crease along the edge of the roll construction angles; pushing to hard will create a sharp bend in the middle of the roll.
Twist the F-1070A and B Roll Construction Angles with the aft vise grip, then strike the roll construction angles with a rubber mallet to finish forming the sharp radius at the aft end of the roll.
