what do you mean by this? this are the mower wheels, its a belly mounted 60" wide deck....short of a brush hog or similar 3 pt implement I can't go any bigger.

I have used this method many times to do my "normal" work(~1-2" stock) The trouble I have is putting the center hole it without the lathe. Yes I have a drill press, put have never had much luck in accurately locating the center & if I miss then I am starting with an irregular cut at 6" and I worry about the machine handling that . My drill press probably needs a good tramming if I am to go in that direction.
yes I plan on a band saw to slice them, but was thinking I would take the od down to true before than slice, but I still cant hold it for that first turning. My plan was similar to bore out bearing cups for ball bearings. and I know concentricity is not crucial, but I would like to do it well to expand my skill set.

I know I can turn it true no matter where the hole is, but I'de like to keep as much material as possible. thanks again everyone!
