I helped a buddy make this in preparation for the nice summer weather. He wanted something that was going to stay put. That’s why the bases are so huge. Materials only cost ~$30 at Home Depot. The bases are 2×12, the uprights are tubafores and the crossbars are 1/2” PVC. I attached the uprights by countersinking some lag screws in the bases. The crossbars are held in place using some PVC couplings Gorilla glued into the tubafores. It is very easy to break down but stays put when together. Only took about 2 hours so all in all, not a bad project. He plans to paint it in the colors of his alma mater.
