Left tank z-brackets - 2 hours
Last night dad and I worked on the Z-brackets for the left tank. We are using Dan Checkoway's method again (we did on the right tank as well) for drilling the z-brackets. For more on Dan's method, see my entry for the right tank z-brackets HERE.I ran out of nutplates and will have to run by Aircraft Spruce tonight to get some more, so we called it a night early.

Z-Brackets - 1 hour
I snuck in one hour today on the airplane and got all the nutplates riveted to the z-brackets, and all the z-brackets bolted to the spar.

Tank - 5 hours
Last night dad and I got a good night in working on the tank. We started by assembling the tank - ribs in the skin, then attaching the baffle to the rear of the ribs. Then we set the tank on the wing and clecoed it in place. The gap between the tank and leading edge was perfect this time, so we didn't have to file down the edge of the skin like we had to do on the right tank.
We used Dan Checkoway's method for drilling the z-brackets on both wings. As of the last time I came to the shop, the z-brackets were already bolted to the wing. With the tank clecoed to the wing, you only have access to the inboard most z-bracket - I drilled (with my 12" #30 bit) and clecoed the holes to attach the bracket to the tank. The next step is to pull the leading edge assembly off the wing. Easier said than done, as the joint plate is attached to the leading edge assembly and it is stuffed under the tank skin. We got the leading edge off, but ended up bending up the rear flange of one of the ribs pretty bad. I was able to straighten it out with my flanging tool, and it is fine. With the leading edge assembly off, you now have access to the outboard most z-bracket. Again, drilled and clecoed. Now, I took the skin and interior ribs off the wing, leaving only the baffle and outboard ribs of the tank still attached to the wing. Now you have access to drill the remaining 5 z-brackets. This is an involved and lengthy process, but it en
