Lantern vises don't get limelight they deserve, Captainleeward's use of such a device is a perfect example.
With a little planning, they can have a handle to grip, a shank for chucking in a lathe, flats for mill or bench vise etc. Facilitate indexing with flats in square or hex form. Even if the [your] frame is a little large, a smaller ID washer will bush the hole.......That's what Toolmaking is all about; evolving solutions.
