My opinion on this is most people do not know how to weld, but there are some of us who do. I know how to weld but do not have the equipment at my home. I do have easy access to it, but I feel that the time and cost of building a rack this way, is out of range for most people who build their own racks out of wood. There are a few exceptions, but most people who have the money to go out and spend on materials to build a rack out of metal, can easily go out and buy a vision rack, or jasonsjunglerack. Just my two cents
