I had quite the day trying to get the small floor piece on the right to work. I had a piece I thought was going to work that you can see in the previous pix. Well, it didn't.
I cut it wrong. Now, I could have probably welded a piece back on and made it work but I got this brilliant idea
that I would make one from scratch rather than use the pre-bent piece I had. What was I thinking? I don't have any tools for forming metal. I finally got it made and tacked it in. Still a little massaging needed at the flange.
