I made adjustable machine feet. I want to perfectly level my Bridgeport mill by adjusting legs. Then some manipulations of parts during milling would become easier, as I could use a machinist level to align parts in vises horizontally. I want them to also be retractable so that I can mount the casters back and move the mill around.
These feet are made from 1"-10 all thread studs and same nuts, welded onto 0.25x1.5x4.75" steel flats.I have not yet welded them to the mill's bottom frame (which is a homemade frame for casters, if you recall, I would not be welding these feet to the actual machine base).
My question is whether I need some set screw or some such, to prevent these 1" allthread studs from working themselves out of alignment, over the years, due to vibration. Or would they just hold in place.
Right now, they are held by the nuts to the extent of being either difficult or impossible to turn by hand, but all are easy to turn with a wrench. (due to changes of alignment that happened during welding).
My gut feeling is that setscrews are not necessary, but I wanted to hear some opinions first.
