This morning I fabricated the parts that strengthen the fuselage where the fuel tank attach bolts come through the side skins. There's a big bracket attached to the nose of each fuel tank root rib, each of which bolts to another big bracket that sticks out of the side of the fuselage about midway between the spar and the firewall, and those brackets bolt to the forward cabin bulkhead through these angles and spacers:
The holes where all this stuff attaches were already dimpled and filled with rivets in my quickbuild kit. Apparently the quickbuilders got a little carried away. I just drilled the rivets out.
Here are the angles and spacers all match drilled to the fuselage skins and each other. You can't really see it in the photo, but I dimpled the thin spacer and machine countersunk the thick one, to let them lay down properly over the top of the already-dimpled skin and bulkhead.
