Sounds like you need some of my wife's homemade chicken soup. That weld cart looks plenty strong enough for the light M211, nice idea on the casters, can it be moved like a hand truck also? Looking good.......
Hot clam chowder with a LOT of pepper, figger I kin BURN it out

Strong - yeah, the part I "re-purposed" is .095" wall 1-1/2" tubing, should be fine with that light a load. Most of what I had for add-ons is .120" wall
Casters - 2 positions, up has the bottom of the wheels FLUSH with bottom of cart frame, down puts 'em against the floor when the cart is level.
Handtruck - yeah, that's one of THREE modes - the two tallest uprights at the front are the .095" wall, makes for a slightly loose fit for 1-1/4" tube nested. Once the rest is done I'll add a hand truck handle that slips into those uprights and STAYS, top of the cross-bar will be just high enough to protect the tank regulator WITHOUT obscuring the gauges. The big tires axle will likely end up right at the front corners.
Then, on the BACK side I'll add a 1-1/2" .120" wall square tube "trailer tongue" just under the frame bottom - 1/4" plates on both sides just where it exits the cart, with a pivot and 2-position pins - down for trailering (2" hitch ball) and up for "flat country" - the tongue will be long enough for easy maneuvering, it can stick up at least 4 feet without getting in the way of anything. It'll also make a nice "lever" so I can take the weight off the casters for raising/lowering. With the hitch pinned UP, footprint of the cart will stay minimal (container, remember?:laughing
I figure "trailer mode" will get it up/down the slope between house/garage and the 2 shops (towed by the ZTR), "hand truck mode" will get it up ramps to the container, a trailer, etc, and "flatlander" mode for actual use.
Good thing I don't plan on FLYING anywhere to weld, THAT might get a bit more complicated
Here's today's progress - finished the second caster mount; the mounting plate needs to be FLUSH with the 1-1/2" tubing it's welded to so it'll retract alongside the cart vertical corner. Didn't wanna mess with gussets, had some 3/8" FB. Figured it'll be plenty strong that way. A small piece of 2" angle mounts the small barrel bolts, didn't wanna mess with more screws but 4 holes told me it wuz OK to do quick plug welds :cool2: I plug welded (more like a quick tack) the barrel bolts AFTER drilling the locator holes, bit tricky OTHERWISE
From the back, the left side gets the 150 CF C25 tank (locked into the YELLOW corner, right next to the big wheel) and the welder goes on the right - This will keep the side door accessible WITHOUT having to remove the welder.
Between the frames there's about 1/2" left over (that isn't taken up by either the welder or the bottle) - kinda snug, but doable. The trailer tongue (fixed part) will exit just under the bottom of the frame, center is between the red upright and the shiny gusset piece. I'll get everything else (including the welder) in place BEFORE deciding how much stick-out the tongue's pivot point will need - I'm keeping a "pick-point" in mind as I do the hand truck handle part AND the trailer tongue part, it'd be nice if I wanna set the whole thing somewhere with the loader.
OK, 'nuff blather - here's the dirty pitchurs y'all been waitin' fer
