By the way... those frags look pretty good.... the blue SPS is awesome under my lights! I better frag my zoas for yah soon! Ha ha!

As long as your supplying the beer I'm in! Glad to hear the frags are doing good, I hope those blue ones continue to color up the way they have been. They just might turn out to be the best mystery frag yet.

You're not going to like this, but if it were me, I'd be getting that tank off there ASAP and welding 45 degree braces on it to stop it from racking like that. 1" is surprisingly strong in compression but if if racks -even a bit, the welds will fatigue and if it fails....<shudder>.

I dunno, you might get away with bolting it but if it were me (and I'm anal, I know) I'd weld it, no question. The consequences of a failure are just too great not to, IMO.

They are one inch welds so i am not worried about them cracking. im just paranoid. one inch of weld holds 1000 Pounds each.

The previous owner used this stand without any problems. Once you install stiffeners the only place that stand will go is through the floor.

That maybe true, but is it welded all around? Only one 1" of weld will act like a hinge and break if it is subjected to back and forth movement.
Too bad I can't help you from here. I have a 110 Volt mig that is portable, and I would not have a problem welding in the house. (already have in my house)

My father-in-law has one too. Just not really wanting to weld inside the house as well. I guess, as a fitter, I am not doing alot of full-on welding.... so I am not what you would consider a "good" welder..... I would burn through in no time.... I hate pipe work. I leave it filled with holes for the welders ha ha!

It is not moving enough to break the weld I am sure.... it just kinda "shimmies". I don't really know how to descibe.... it's enough to notice the movement. But thinking about structural work... a lot of it is bolted connections.... even bridge work is bolted connections so I am "hoping" I can do the same. My only real concern was the drilling of holes with the weight on top.... wondering if it would buckle.

I really appreciate all the ideas and input.... and I am sure I may have taken you up on the offer if you were closer. Next time you come to Ed let me know.... I'l have some cold beer waiting ha ha!

1" of weld is only as good as the weld it self, if there is so much as a hair line crack to would not take much to rip. I would think about bracing the tank with maybe a temp 4x4 bridge just to hold the weight before drilling the holes in the frame. But who really know what might happen. I always air on the side of caution.

I thought of something else then. If you cut triangles from 1/16 or 1/8 steel, then you could drill through the HSS horizontally and attach the triangles aginst the HSS instead of underneath. At each corner. It would increase the horizontal width of the stand. If you understand this your good. Hard for me to describe with words.
