No real spectacular events to show today, but I'll let y'all see what little bit got done anyhow. Since I am still waiting on parts to complete any of my other projects, I decided to go ahead and start raising the waist gunner's floor back up to it's original height. This one is pure fabrication, as I haven't come across the drawings for it, but also because I need to make storage compartments under the floor for the "garage sale" stuff that we carry along with us on tour.

So, although it too is not completed (I'm tired and going home for the day), here is the play by play on a floorboard bulkhead...
The first thing I had to do was determine the height the floor needed to be. I did this by clamping a piece of solid, square, aluminum tubing to the existing, correct height, floor structure. I then put a bubble gauge on both the structure and the tubing to ensure they were the same...
The next step was to get the general size of the aluminum needed and cut the blank out. Then I got some posterboard to work with so that I could cut a pattern out for the corners of the aluminum sheet...
Once that is done, I went to the sheet metal brake and bent the top of the sheet 90 degrees at the previously measured location, which if done right, should put the level of the floor right where I want it. I also took a piece of aluminum bulb angle and attached it (with clecos for now) to the bottom of the bulkhead for rigidity and an attach point to the fuselage later...
Here's just an initial test to check the fit...
It's really the little things that take all the time on projects like this. For example, when doing that previous test fit, I noticed that I needed a cutout for some major structural rivets that interfered with how this bulkhead was going to attach. So, after a little thinking (the hardest part for me), I managed to get the measurements that I needed and cut out the area in question...
Here's the area I just described, with the bulkhead in place. Looks like it's gonna work out just fine to me...
I still have some stiffeners and other little odds and ends to do to this piece, and will hopefully get this completed tomorrow morning. I'll give y'all another update whenever something more interesting takes place here.
