Here is a simple modification I carried out to make life easier and quicker when needing to hold small components in my big milling vice. I set the vice up true and square to the mill, then simply milled a ledge into the top of each vice jaw at the same height (Photo 1), about 3mm deep in both directions. The finished ledge can be seen in Photo 2. In my case I also tidied up the jaws of the vice which with much use over many years had become quite significantly marked. To ensure that the vice jaws are parallel when machining the moving jaw, close the jaw onto a parallel that is wide enough to allow your milling cutter to clear the fixed jaw. Making this modification allows small parts to be held securely in a large vice without having to resort to balancing the part on parallels.
