You're beginning to sound like an old tool & die man I know near Lincoln, Nebraska.
Old school rigger and made a bundle doing specialized work during the heyday of tool & die making. He travels the U.S. looking for good old american iron, beat up but not put away wet.
Takes it back to Lincoln where he completely renews the piece, rebeds and resets it and makes sure it works perfectly. Then goes and hunts up another. Last time I visited his place, he had a two acre Morton Steel building about 3/4 full of operating equipment, most of which is unique or rare.
