That otta work! I'm going to make me a stand out of an old Ford Magnum 500 factory mag wheel and fill it with concrete to make it stable. Its got a 2 inch center hole so I'll get some 2 inch heavy wall tubing and cut to lenght. Might even fill the tube with concrete.
Yes, an I beam for each one, 4"x6". They do weigh a good bit, but not too heavy that I can't pick them up. One weighs about 20lbs per foot, and the other about 15lbs per foot, and they are about 34" tall. The top and bottom plates are 1/4" thick.
