Bought this tubing to make skid shoes for my tractor's rear blade. The material is excellent for that use and I wanted to use it in conjunction with "Cold Rolled Steel A513 Drawn Over Mandrel Round Tubing, ASTM A513, 3/4" OD, 0.37" ID, 0.188" Wall, 12" Length " but as luck would have it, the smaller 3/4 OD tube was the exact same size as the ID of the 1-1/4 tubing I bought and would have to be machined to  fit.
