680lbs is very little weight. I've seen 3000lb pallets stacked on top of an empty drum. Pretty sure they stack full drums at least 6 high.

A T collar or other way to support the welded connections and keep them perfectly plumb would be very important; as would cables or attaching to your structure. Might want some sort of barrier around the base so someone couldn't accidently dent the bottom couple of barrels.

So the Jones are going to 4 stories now?
