Well, just so you guys don't think I have been goofing off, here's the latest struggle.
I have been making the aluminum panels that fill in between the tube structure. This panel has to jog around the E brake. The tunnel is narrower at the top, so the panel leans in, while the brake handle is vertical.
Photos 1 and 2. Day 2. The panel is oversized on the top and both sides. I used the hydraulic press to put the tapered offset in the bottom 1/4 of the panel. It looked like a Pringles chip. Later, I used a hammer and wooden dolly to form inside the orange line.
Photo3. After a couple hours of goofing, which included planishing and wheeling and making it worse, I finally did this. The gap at the top is how much I needed to stretch the metal. I wheeled it until it got almost flat. Then worked on it with a hammer and blocks and finally it fit and was pretty flat. But there were lots of scratches, hammer and wheel marks. Some of were there when I started and most, I added.
