Tonight I laid out, drilled, and reamed the center bolt holes in all seven z-brackets for the right tank. Per the "Checkoway" method, I located the holes in the inboard bracket 1/16" outside the centerline of the flange (relative to the web) to allow room for a socket to torque the bolts from the front, and 1/16" inside the centerline of the flange on the other six to allow more room for riveting the bracket to the tank baffle. I first pilot drilled the holes #40, enlarged to 5/32", then reamed to 3/16".
The seven fuel tank brackets arranged, left to right, outboard to inboard.
