I laid out the hole pattern on the hinges as the plans say and clamped it to the leg fairing. Then I drilled thru the fiberglass fairing and thru the hinge at the places marked. Cleco as I went.
Then I countersunk all the holes.
I took it all apart and deburred.
I primed the hinges.
I rivetted the hinges on with my squeezer. Plans call for a hand squeezer. I don't have a hand squeezer. But I hold this pnuematice squeezer in my hand so I deced that counts.
