OK, as promised (or at least insinuated

)
Just in case anybody thought I just grabbed a link and LIED about it :laughing:

I got that cart @ Amazon, turns out it was basically IDENTICAL to the HF cheapie, but with the added BONE-US of getting to pay about $15 MORE (yay) - crappy little 6" wheels, crappy little no-lock casters; both got replaced - 10" solid rubber wheels, 4" (sorta) locking casters. the hole for the rear axle seems to be made of tungsten carbide, wiped out 2 drill bits enlarging it to 5/8"

- but it's a LOT smoother even on concrete...
Progress - (note the pressed-in 2.5" tube supports in the one that will NOT have cross-tubes to stiffen it)

- That last one weighs right at 99 pounds; That and the other two pyramids that have TWO stacked 3x8 tubes, will sit on one of these -

- got 3 of 'em off CL last year for $60, finally found a use for 'em besides tryin' to get 'em NOT to drag the ground on my itty bitty 45 horse tractors
Here's the LAST stack of "glu-ables", they're now actually "glued" except for the second row of 2.5" tubes -

- After this I'll do some touch-ups on welds, grind the holes flat where necessary, cut some 1/4 plate, "de-critter-ize", etc...
Last one - here's my short(ish) term survival setup, actually
makes it semi-comfy to be in those dark reddish brown containers clear to the back end when the sun's out -

- that roll-around rack was a GIFT from a buddy - frame is 2" .120 wall tube, 3/4" black iron pipes are 12" long, came from a parts house "purge" where a friend of his worked - that 3' fan sits on the top row with just over 1 INCH of clearance to the ceiling :thumbsup: - just did that this morning, REALLY helps the two smaller fans get the heat out.
Got a line on some "greenhouse kits" that include a shutter fan, louver inlets and controller - gonna order ONE of 'em to start, if it (and my skills) are up to the job I'll get 3 MORE for the other containers - then (hopefully) no more "morning and evening rounds" opening up, fans on, then reverse at night...
