I have an old Craftsman drill press vise I inherited from my grandfather years ago. There isn’t anything special about it other than its sentimental value. Under other circumstances I’d just trash it.
The leadscrew binds pretty badly during parts of its rotation - it is surely bent a little. I can fully open and close the vise but it takes more effort than it should.
My question: Is there a practical way to straighten the screw, and barring that, would it be terribly difficult to make a replacement?
The threads are a sharp V but I haven’t measured pitch or removed the screw to match it to a die for confirmation.
Edit: Screw is about 1/2” diameter and 7 inches long.
