Making this lower section of the tailgunner's section has been challenging to say the least. It may just be that I'm having a bad couple of days, or it may just be that it's out-smarting me. Either way, the scrap pile and hours of wasted time are accumulating. I didn't take as many pictures of the process as I probably should have, but here's what got done today...
The first thing I did was to make a little brace to hold the aft portion of the lower bow at the same height as the front of the bow. Then I made a "buck" out of wood to simulate the shape that I will be needing to make the aluminum skin into later...
This is pretty much how it all starts. A buck as a pattern and a flat sheet of aluminum. Since this will obviously have a compound curve, I am using 2024-0 aluminum. It is still in it's "soft" form which makes it able to be worked with the shrinker and English wheel better...
I've forgotten how many pieces I scrapped out before I got to this point. My mind just isn't clear enough for this kind of work today I reckon. But here is the first two pieces of the puzzle...
After getting frustrated with how poorly I was doing with that skin today, I went ahead and fabricated the lower bow support angle. It is made up of a bulb angle and two straight alumunim angles riveted to one another. This pretty much duplicates the factory setup on the old tail section, only with the different shape to accomodate the gun. This was kind of a fun piece to build. I wish I had thought to take pictures of it as I went...
And here's the previously mentioned bow support clecoed into place. You can at least see the general direction that I'm going here. Hopefully tomorrow I'll be able to get my mind in the game and be more productive...
