Lift Bundle End Supports repurpose thread

How tall are they? Grinder stand? Bench drill press? Can you Weld 'em end to end to get enough height? And sometimes, ya just gotta say "screw it." I've got junk around here I should just give up on and take to scrap., one big piece I had for YEARS . It was an odd construction bench made from a Model T frame that had a large structure, formed the front legs and extended up and back at an angle to form a slanting back, with sorter legs "triangulating" towards the rear. IT WAS AN operations / equipment rack for a 1920's !!!! defunct radio station!!! in my home town. I used it for a work bench got in in 64!!!!! It sat in the shed through my Navy years (68-74) and I finally drug it up to this house in the mid 70's. I FINALLY cut the damn thing up sometime in the 80's and used some of the material "for something else"
