The base, where the project started and almost ended. I figured out how long it needed to be and did my cuts on the two cast iron bases I had. I got a surprise when I put the two pieces together. The bases were two different widths. One was 17 inches and the other one was 16 5/8 inches. I almost scrapped the project but decided the see if I could bend it and make it work. I used a couple friction jacks, one to squeeze and the other to spread until the two halves lined up. It was then welded and finished off.
