    Giant vise

    Hi all!
    I just found this little beast!
    There are no marks of brand, the weight is pretty high, I used all my strenght to lift from ground to table
    The conditions seems very good, there are two marks of carelessness, the threaded rod is in perfect shape.

    My milling machine is tiny, I could Mount on the table for short time. I'm thinking about using this vise on the bench or a dedicated support as a normal big vise.
    230mm width x 250 stroke
    Any advice welcome

    Possibly used with a planer, it is a bit large for a small mill.

    In your middle picture with the vice in end, that would be my choice for use. Making knife blades, sharpening mower blades etc. Great complement to the bench vice you have. Great find.

    Now that's a vise! The serrated jaws and nut on the moving side tell me it is cam operated jaw. The screw gets size close, the operator locks material with a simple motion. With the flat sides it can be mounted vertically too; that is not very common.
    In shot with caliper for scale, about an 8" 200mm opening, an roughly as wide. And jaws are removable, for soft jaws, fixtures and other convenient workholding.
    Sincerely,

    Is the cam action any more or less secure than tightening all the way with the screw?

    Or is this just for ease of operation on multiple same size parts?

    Yes. If it is actually a cam operated vise. You adjust clamping size [screw] on like sized material, to where jaw isn't contacting to switch workpieces. Cams usually impart .020-.030 movement, sometimes more.

    One variation has a serrated nut. The moving jaw bolts on.

    Funny, I just stumbled on this post from a google search. I have one of that exact vise made by Hartford Special Machine Co.
    I occasionally use it on my milling machine.
