I have some large mill tables & just wondered how these would work. Thanks! Eric

I was using one a few days ago - an older USA made version (I think...). I can't get the clamping forces I get with the Kurt vices, and it does tend to lift a little, but... sometimes it's all that will let the part fit.

Alternatively.. if you have a couple of decent surfaces, this:

this style is useful for certain set ups, action is downward so it locks things solidly.

I recently got one, but I haven't had a reason to use it yet. Most of the parts that I make will fit in one of my Kurt vises, so I got the table vise for emergency's. Mine has 4 set screws that are angled down towards the table behind each jaw. I would assume this is so I can give the jaw a little nudge at the top so parts will want to stay down, although with the jaw opened, this wouldn't work very well.

Mine was made by Universal Vise and Tool, which is no longer in business it seems.

Ive used those on shapers in the past and as already stated, theyre very handy when you have very little "head room."

Thanks for all the great ideas. I'm not sure of the qualty of the chinese one in my 1st post. I think I'll look for something better.

Agreed.


Just make sure you have a fixed jaw that holds perpendicularity, and and a movable jaw that clamps the workpiece down on the table.

If both jaws can swivel to clamp down on the table, you can never work to right angles. Only parallelism!

Cheap jaws will warp so your workpiece will move upwards from the table, so you need to hammer it back down. 8-[ ]

With all the incurred inaccuracies.

I made mine, and it's handy..... I don't use it as much now that I put a swivel base on another vise, but it works nicely.

on mine I leave the front screws slightly loose as I set it up, then pull them down tight. But mine has 2 screws in line instead of two across.... and teh "pusher jaw" is separate from the "moving jaw" I can tighten the back and later the front, for a pull-down action. (Mill has one slot down the middle)

They are handy for the times that nothing else will do. One thing should be kept in mind though and that is that they can impose a bending stress on the mill table, particularly when used on a long part that spans the saddle. I would still use hold downs when possible and not leave a part clamped in the two piece vise for any longer than needed for machining.
