I wanted multiple camera angles for filming work at the lathe. I like an “over the shoulder” angle the best, but sometimes my body got in the way or threw a shadow, and I wanted a camera directly above the lathe as a “B-Roll” to provide a second choice for any given scenario.
I found a nice solution. A “super clamp” with a 3/8″ stud is clamped to a piece of timber fastened to the ceiling joists over the lathe, and a ball-head mount is on the clamp. With an Arca-swiss quick-release mount, and plates on all the cameras, I can very quickly install a camera directly over the lathe and facing down.
This is working quite well. I film every scene with both cameras, and then have the option of cutting between camera views like this:
