Brief Description:  Attach Elevator to Stabilizer

Today I linked the elevator and the stabilizer together with the big, long piano hinge. I started off by re-cleco fastening the forward side of the elevator internally so the rib clecos wouldn't interfere with the process. Then I cleco fastened the aft tip ribs and installed the fiberglass tail tip (white in the pictures) which I professionally locked in with duct tape. Then, with the hinge cleco fastened to the stabilizer, I lined up the elevator between the 2 aft tip ribs and slid it forward until I could work the back half of the piano hinge up under the top skin of the elevator.

Once in place, it was a matter of centering the elevator precisely between the 2 tip ribs (5 mm total space to work with!) and ensuring the elevator was flush against the spline of the hinge. With the tip ribs ~8 feet apart, I probably walked a few hundred yards going back and forth, measuring and remeasuring, to make sure the elevator was precisely centered. I eventually honed in on it close enough to use duct tape to freeze the position. After several final checks, I marked the hinge through the pilot holes on the elevator, removed the hinge, drilled the marks, and reinstalled the hinge using clecos. Looks like that 5mm space was enough!

Looks like this on both ends - not a lot of room to play in there.
