It's been several days since I last worked on the project because I went to Nashville for the long weekend! I picked up right where I left off last by continuing to work on the tank reinforcement brackets. I drilled the small backside doubler piece to the inboard bracket on both sides as well as drilled the one for the outboard ribs. Here they are all drilled up.  After that, I moved onto to making my capacitive fuel senders. I match drilled the plates to the specified ribs.  Once those were drilled I clecoed them to the rib, the rib to the tank, and the stiffeners to the tank to see where the plates were too close to the stiffeners (min distance is 3/16"). I marked out roughly 1/4" around the stiffeners just to be safe.  I cut the offending area of the plates out and then drilled the plates for the nutplates. After some double checking to be sure I was putting them on the correct side of the plate, I dimpled the nutplates and the capacitive sender plates and then riveted on the nutplates.  After doing the fuel senders I became very unproductive. I got out the fly-cutter and fired up the drill press to cut these giant holes on the inboard fuel tank ribs. This is by far the scariest tool I have used but I managed to make the holes quite nicely despite hiding behind my toolbox while doing it (I had horrible visions of the cutter flying off and impaling me or breaking a shin bone so I went to battle using the tool box as body armor...)  Earlier today I ordered some fuel tank sealant, the tank tester kit, and the pre-made fuel pickups from Van's so those should be here around Friday or Monday. Also, in the midst of my unproductiveness, I cut out the anti-rotation brackets and ordered some 5/32" and 3/16" clecos (black and gold colored) so I could do the fuel tank access panel drilling. I closed out the night by staring at my fuel caps trying to figure out how they get attached. They are slightly contoured but I was having a very difficult time seeing the mid-point of the contours so maybe on another day after some sleep it will be clear to me which way they go on.
