Ken -- welcome.
Lots of great folks on this board, who are fantastic is teaching things to a noob, like me.
My plane has turned into a long term project. 2024-T3 0.032 is not fun to form. That lower bend is a radius around the tube. There will be another panel, but was attempting a round lower form rather thank boxed. I'm using a pine mallet (2x4) for forming duty.
What are you building?
