Yea 4X, I was asking about taking that flange off in an earlier post, but to be able to run my M35A3 wheels with dish out. Your idea of doing it for duals makes it so the axle (frame etc) is within the legal limit, not narrowed. Good job cleaning it up, it's a LOT of work. Obviously it's cast iron, not steel. I know it's a lot of work cutting Iron
I took a job changing from a flat belt to a 6V with flat backer on a 200 hp, 6' diameter bandsaw. The outer part was no problem but the cast iron was 4" thick and about 10" wide on the shaft. I couldn't damage the shaft. Normally I use LP for cutting but I rented two of the large acetyline for that. Eight 330 CF bottles of oxygen and about 10 hours later I had it in 2 parts and didn't mark or discolor the shaft. Heat melt blow away, heat melt blow away...
Even with a lathe, torching may be the quickest way to remove the bulk of that flange. I don't think my LP would do it,maybe it would, but acetylene gets hotter. Edit2....I see you used plasma, how did that do (it looks rough but may not have been that bad).
I asked if anyone knew if a deuce hub would fit, but don't recall anyone responding. Just a guess but outside of tire to outside is about 7'8"??
Good work....I may be doing the flange trick very soon also. Thanks for the detailed photo's.
Edit...just noticed that is a LMTV bed..
