Limitations of the vise

It is not recommended that you clamp anything higher than 1.25" off of the bases, this may cause an unwanted moment that can cause jaw lift. So if you plan to use a 1.71" flippable Carvesmart, this may not be a good application.

While a 4" CarveSmart or 4" Dovelock masterjaw will fit, it may block the mounting bolts. 

The fixed jaw is removable, but it is not recommended to do so (although it does have precision dowel pins within it). It is ground to be parallel to the precision pins of the base. It is also designed to be removable to make it easier to replace if you machine them by accident as well as to aid in grinding.
