I made this Small Workshop Lift-Table a few years ago and use it almost daily.
The table is raised and lowered by using a 1/2 horse drill with a socket attachment to turn a nut welded to the end of an ACME threaded rod that goes through another ACME Nut.
As many of you know, ACME thread is considered a ‘Trapezoidal Thread Form” used for simple Leadscrews because the thread’s tooth shape wears better and allows it to carry a greater load much easier than common threaded ‘ready rod‘ ... However, you can use normal threaded rod but it will take a more hand drill torq to raise and lower the lift.
Depending on the direction the threaded rod is turned with the hand drill the lift lowers or raises.
The Lift-Table can be lowered down close to the floor (I store mine under my Jeep) or raised to over 5 feet …

When I built this Small Lift-Table didn’t think I would use it as much as I do; however, it has turned out to be a wonderful ‘Back-Saver’ and I just used it again recently to transfer a heavy Sand Blasting Cabinet full of Abrasive Media from a higher table to the new lower STAND I fabricated out of leftover ‘scrap’ metal.
