This vice clamps with a downward pressure (desirable) or at the least straight forward. THere is NO upward push when tightening.
I got mine (which is the same as the picture) from ENCO (model 425-7251)while on sale. I think the total with shipping at the time was $99. I'm real happy with it. I tell you though, it is a beast but managable. The mass adds to stablizing the cutting action. Since my mill table has only two slots, I mount it with one t-bolt in each slot and square it to the axis, mark the new location on the vernier and go from there for a rough location of any angle I might need.

The top has keys to mount in the T-slots if taken off the swivel, but they are 5/8" where my table has 1/2" slots. I don't need this, but I may mill down the keys to fit. I think I will need an extended auxillary table to mount between the vise and mill table to do this properly.

The other day I had the vise reversed (jaw screw wrench on back side) to keep the part moving over the table center on the ways during cutting to keep weight distribution balanced.

It also helps control coolant run-off with the channel system built into the casting.

The only part I didn't like is the collar that takes the reverse pressure when tightening. The "seat" could have been machined a little smoother as when you loosely crank in the jaws you can feel the surfaces of the collar and casting rubbing rather unsmoothly. But this dosen't affect the jaws and slides. They are close and well machined.
