Default Main Gear Leg Fairing Clamp

This is an alternate to the "fiberglass finger" method of clamping the Gear Leg Fairing with a breeze clamp.
This seems to work really well. Fabricate two of these. I made them mirror to each other so the outboard nut plates are higher outside on both port and starboard. I oriented the breeze clamp so the access hole to adjust it is on the inboard side. Aesthetics.
It's easier to lay it out, drill, dimple and install nutplates before bending and cutting relief holes.

Attach it snug but not tight. Drill the screw holes in the fairing and the access hole to adjust the breeze clamp. Screw the fairing to the clamp. Adjust the fairing. Tighten the breeze clamp. Easy peasy.

Edit...
The clamp works better if the lower nutplates are outboard. Drawing shows them the other way.
Reason is access from under the wing. It's pretty close as it is so lower nutplates on the outboard side are a little easier to put screws in.

Default Great!

Neat solution. What thickness material did you use? Are you planning to radius the cutout corners a little bit more?

That's what I did 1000 hours after the fiberglass finger method. May as well do it now...

Final two are .032". They fit pretty good.

I made several.
First was .025". Too thin.
Next one, I didn't offset the nutplates. Screws hit each other. Plus the breeze clamp hole was way off. The last fit the shape of the fairing much better.

I promise to spend countless hours making them structurally perfect after the fairings are fit. Even though it's not a structural part. I don't want to make another set!

I love it. Very timely too. Have been trying to figure out a more functional way to attach the fairing.
