I was probably 6 times faster in the shop this week. I worked exclusively on the Power Cube frame. I welded the rest of the bottom square and all of the top square. The height of the steel frame may be changing so the uprights that I have are probably shorter than optimal. That means that turning these squares into a cube needs to be put off. For now I've decided to move from working on the frame to working on the hydraulic tank. This will give me time to think about the frame dimensions while still making progress.
Tom, who has been helping me with various Power Cube related things. Hopefully he can help me shore up my understanding. I'm also hoping the diagram can become a useful part of the Power Cube documentation.
