Thanks guys for the explanation of how they were put together. It doesn't seem like they would be very strong like that, but they obviously are. I guess I'll just leave mine like they are and not try to get them re chromed.
I saw these on craigslist a few days ago. Cragars with 3 bar spinners. I don't know if they are worth anything, and it doesn't say what size they are. Looks like they might be the early style wheels with direct bolt pattern.
