I'm making some screws for my bandsaw with integrated sliding tommy bars. To fit them, the tommy bar will have to be slid back and forth to avoid various bits of vice etc that will get in the way. Once they're tightened, they should only need to turn 1/4 turn or less to loosen them up enough to adjust whatever they're clamping, so the tommy bar won't need to slide. Given that the bandsaw vibrates a fair bit when its cutting, I thought it would be a neat solution to have a little brass knurled screw in the head of the main screw that tightens down on the tommy bar and holds it in place.
I'll hopefully finish the main screws this evening so I'll post some photos in case that doesn't make any sense. The bodies are already done and marked up with the angle that I'd like the tommy bar to sit at when its tightened; just need to cross drill the hole for the tommy bar and add the M6 locking thread for the brass screws.
Here they are:
