Didn't make this one in 7 minutes due to being at a wine appreciation class.
What you should due for your tube is go and see if the supplier will let you check their stock and select the best; hollow structural steel can vary a lot. I have used many feet of 2" x 2" x1/8" and sometimes a shipment will be square to within better than .01" other times as bad as 1/16". We cut the tube into 2" lengths to make little bevel gear boxes so square is important which is why we measure it.
