I've done lots of bits and pieces using a record drill vice. The small one that was popular for use on Myford vertical slides. They really need attention to the alignment of the jaws especially the fixed one but hold well enough.
It was permanently fastened to the table most of the time. While nosing around on ebay I saw one of these used and at a decent price.

Crazy design, just look how thick the fixed jaw is compared with the cast iron behind it but I think it will be fine for light milling and more flexible use wise than the record one. Guess they did it like this due to the strength of the base. It wouldn't be suitable for hefty cuts but is well made.
I also have a conventional 4" milling vice. It would probably be perfectly happy on a 5hp geared milling machine. That in my view limits it's opening capacity.
The worst type I have ever seen but it could be a bad example is the small ones that tilt with a metal strap on the side to hold it at a set angle. It came with my dore westbury and if the person who sold that use a decent vice on it and didn't end mill with a blunt slot drill he may have been a lot happier with the machine.
If I needed to do bigger stuff I would probably add one of the 2 piece ones to my kit hoping it has removable jaws. as that's not a bad idea on any machine vice.
