Below are some pictures of a more complete mockup of the oil cooler cowl. In the pictures, the two side pieces are reversed to allow for the pieces to be held together with binding clips.
I intend to make the cowl out of 0.032" 6061-T6 aluminum sheeting. The side pieces will have metal tabs that will be folded over to allow for riveting. A 19 row oil cooler will be mounted in the back of the cowl. The leading and trailing edges will have hems folded into them to give them extra strength.
