Years ago I made several wheels by cutting the center out of the RH5 wheels and welding them to a 6" open center rim. And I welded some to 7.50x22.5 open center wheels. But new open center wheels have gotten crazy expensive. We have a brake drum lathe that we used to cut truck brake drums with and they got pretty true. If you find an old farm truck with usable wheels, you can probably by the whole truck for the cost of wheels. I think 1955 and later wheels are more plentiful than 54 and older. I still have some spacers somewhere that I had made to use the later wheels on the older hubs.
