Lots and lots of drilling on the fuel tank today. I match drilled all of the rib to skin holes, as well as the baffle. Then I countersunk all of the holes in the baffle/skin holes and enlarged the holes along the edge for the screws that attach to the spar.
The platenuts for the inboard Z bracket get attached to the spar instead of onto the Z bracket. I'd forgotten how big of a pain this was on the last tank. I wish I had done these before I had riveted in all of the ribs. There is very little room, plus there's a doubler underneath that makes bucking really difficult.
I started prepping the Z brackets for the platenuts using a jig to drill all of the holes.
I had to pause there, because I can't seem to find all of the platenuts I need for the brackets. If I have to order more, I'll probably just go ahead and order a bunch of various hardware. I can't exactly get this stuff locally, so just being short one bolt means $5 in shipping. I'll get some of the most commonly used nuts and bolts, platenuts, washers, etc and hopefully have enough to spare throughout the build.
