narrow rim BAD wide rim GOOD

Thanks got some results. Looks like a guy can build a brand new all steel 15"x10" with 4.5 bbp for $90 plus whatever shipping and taxes are.

Used to be able to buy em from stockton,but they are closed as of march this year.

But it stil leaves my original question unanswered,which was where could I get material to widen what I have?
