Larger wheels would make it a bunch easier to roll around, store some heavy stuff on the bottom shelf and that will improve its stability. In a moment of weakness I bought a Harbor Fright (sic) cart about that size - truly a piece of junk, I should build a replacement.
Yes, for the gas bottle. I was going to make a small square from angle iron, weld it to the back side of the bottom shelf.
I made a similar shelf and welded it to the table I built previously but I should have paid more attention in math class because the shelf came out twice as big then it needed to be for the tank footprint. :nerd:
