I hope to start welding this up this week. I know it looks a little rough right now.
Looks pretty slick but I think I'd have some outriggers for stability. Looks like you have a narrow base supporting the wider table top. Maybe it's just the way it looks in the photo but you can't be too safe especially with a heavy top.

Took the advice and made the table top smaller. It will now be 24"x36". Took about an hour to cut through 36" of 1/2" stainless. Having fun, isn't that what it's all about.
X2 I have some equipment but usually no raw materials around though.
Does the top wobble? If so maybe add set bolts to the larger square tubing to clamp down on the smaller square tubing after you set the height?
