It's only happened a few times so far, but I've found I needed to remove the mill vise to facilitate a larger machining project. It's probably an easy routine task for most of you to re-tram the vise, but for me its a frustrating half-hour. I'm wondering if it would be any benefit to mill portions the edges of the cast vise base to create a flat and true surfaces. These sections of milled edge would be located to somewhat align with the t-slots in the table.
When I know I'll need to remove the vise, I can install a pair of machined round pucks using the table t-slots such that the pucks are tight against the machined edges of the vise. When it's time to reinstall the vise, I just hold it against the two pucks and tighten the vise.
I'm sure it won't be accurate to the thousandth, but to the few hundredth is close enough for me.
