I left 2 stock steel wheels with light damage at Weldcraft in Livonia, Michigan. They thought the other 2 were good enough. The cost is $35/wheel, so not bad.
They thought that many types of old steel wheels were probably not so good even when new. Mine should be a lot rounder and straighter when done. The outer rims have bent outward somewhat where they have hit potholes and that left a flat spot in the circumference also.
They will also widen steel wheels, but not with a new rim which they call a "barrel". They would cut off one side of the rim and weld in a hoop and weld the rim back in place, so you would have the same rim thickness. Cost is in the range of $175-$225/wheel. I'd just go for new Minilites instead.
They can be contacted by email which on their website. Photos can be sent to the owner to discuss work.
