Are you talking about Tim Miller in Goddard?
@AaronD if that’s the same guy, Google search Mainz and assoc. The map takes you to the old man’s house but you’ll see the welding and scrap shop just west. I have bought a lot of steel from them over the years. Good price and better than the yard but sometimes it has been sitting for awhile and has some rust. He’ll also order stuff you need if he doesn’t have it. His prices are all based on what he paid, which is fair.
If you need new, clean metal, amr is decently priced, compared to metals supermarket.
If you need something odd like tool steel or just want a small portion that isn’t rusty like the yard, though, metals supermarket does the trick.
