Cutting short stock in the bandsaw

[Toolmaker51]

The real mystery; why aren't such vises fitted with a jack-screw in the first place?
Some here [HMT.net] posted versions with a quick nut, spring loaded like the clip for a Bridgeport quill stop screw. Another was just slotted out to major diameter of 3/8" rod or so. Attached to back of jaw poses no interference.
But at the same time, machine shops all over town, with talent-time-resources NEVER have one. Always hard to fathom, logic that can't trade a couple hours labor for a long-lived and handy device. And they ignore guys make-shifting with a clamping stud and flange nuts; over, and over and over....

If anybody fancies one of their own, use an ACME thread; V-threads collect chips that harder to remove.
