    The Chinese vise is great if you replace a few things...

    1) The Bearing
    2) The Jaws
    3) The Pin-Block
    4) The Vise Screw
    5) The Bottom Half
    6) The Upper Half

    You can keep the rubber donut if it came with one...

    Thee things are not rocket science. I use a bowling ball in a PVC floor flange with a machinist vise bolted to the top, no bearings etc.. As simple as these are, a little tune up of the moving parts should get you going. Take it apart, check the above listed parts, most likely you have a burr somewhere that is hanging it up. A little sanding will clean that up. Or the bearings have sat for so long the grease has caked in place. Mess with turning them for a little bit and see if they will loosen up.

    Thanks DC, I found the problem, the top half pilot bearing is drilled crooked, spins very free when tension is backed off, but then it is so free as you might as well hold your piece in your hand, as soon as you apply pressure so you can grave and apply a little hand rotation it will be free then bind, I tried greasing the ball to stand contacts but then you lose you vertical axis......................on fleabay it goes, someone else need it more than I. arggggggg, I don't have any more doors to stop, and I won't buy a bigger house.

    I've been thinking about your dilemma, and I have thought of several uses for a Chinese (or indian) Ball Vise...

    1) A wrecking ball for a doll house
    2) One-Handed weight training
    3) A cannon ball for civil war reenactments (Black paint required)
    4) After it has been painted black for the aforementioned application, you can then put a fuse in the jaws and for halloween dress up as a villain with one of those cartoon anarchist bombs that looks like a giant black Cherry Bomb... (Picture Snidely Whiplash and/or Boris Baddenov)
    5) Tie a string to it and use it as a plumb bob to find the "approximate" point before using an actual plumb bob to find the "exact" point... being in range can be VERY helpful.
    6) Practice engraving on irregular surfaces that somewhat resemble a sphere.
    7) Kayak Anchor!

    There must be more...

    Personally, If you EVER intend on getting a scope, I would get a nice turntable and keep the thing... My ball vise is an antique that was given to me by the knife maker Mike Lovett, and it is a smooth as SILK... but... It's locked down and sits on a turntable. A Chinese or Indian ball vise would work just as well under a scope.

    I know this a old thread, but I bought a offshore 5" ball vice and indeed it did have a tight spot on rotation.
    My solution was to install a short 1/4 inch diameter stiff spring under the adjustment screw about 1/2 inch long. Mine was a longer spring cut down.
    The spring allows the plastic plunger to ride over the high spot. Mine is so much smoother now.

    Actually I wish somebody would make a vise that doesn't turn. I would much prefer the vise locked and using a turn table.

    Easy, just replace the brake mechanism with a bolt.
