Annular Cowling Piano Hinges

I spent the some time after work working on the cowling since my order from Spruce came in last night.  I received my piano hinge for joining the two cowling halves.  I chose to spend the extra money on the extruded piano hinge which is a fair bit stronger then the rolled piano hinge.  I marked out 1 inch on either side of the joint.  and then marked out the rivet line.  I plane on using countersunk 1/8″ rivets to attach the piano hinge.   I marked both sides out and used 1 inch spacing for the rivets.  I drilled out the top side using packing tape to hold both halves together.  Below are some photos.
