fermenter legs *Caution Math Requested*

I need to know what size tubing to get for the fermenter I am building. The link shows the hopper. However, I will be welding 2 55 gallon drums to the top of the hopper for 134 gallons. I was hoping someone knew where the legs should go on the hopper and what size.
Thanks

Jim Bieberman did the same thing, look at his project

The weight is 79 gallons which is 8 lbs per gallon. Then the fermenter 44 lbs for the hopper plus drum is 50. I get 726 lbs. + 20 lbs in misc.
So the question is what size 304 stainless steel legs do I need for 750 lbs?

My 500 gallon's tank legs are made out of 3-1/2" stainless.
