High-quality black-and-white photographs of large old machines and tools

In an odd way, this explains equipment and PILES loaded onto adjacent flat bed carts, in the photo rather clearly.

I'm honestly constantly amazed at the deep specialization of the hobby world. A store devoted to HO and N scale models of just steel mill equipment. The advent of 3D printers has been revolutionary for this niche.

(all the photos of the actual parts they sell look like they're resin-printed. )

Interesting too, swivel body casters not plate mounted or ball-transfers. Appears they swivel on each mounting post; and at least one seems to have a coil spring for height adjustment. Unsure how all those were leveled with shear platen, or extent how many we don't see.

Leveling would be fairly easy. Start at machine and work your way back while dragging a piece of sheet metal behind you. If it rolls from where it starts to where you need it, you're done.

Agreed, but still wonder how well it works between big differences of weight and size.
It does have me re-thinking a ball transfer table [tramming into plane] vs. individual posts, becoming the preference
