I think this is my fourth installment of an exercise on my own. I followed a drawing from "Technical Drawing with Engineering Graphics" on page 687 in this case. I realize while I am writing this that I did not add the Jaw Plates, but I think enough is given here for critical evaluation.
For the square screw (acme), I used the Revolve tool and set a pitch of .125. I used a typical pattern for one tooth and revolved that into 36 turns if I remember. I had to 3D slice off one half at the end. I don't have as much confidence in the internal threads, but used the subtraction (keeping the subtrahend).
So, here is the vise.
