I'm brand new to machining. So new that my machines haven't even shown up yet. I'm getting a Craftex CX600 Mill / Drill. The working surface of the table is 20"x7" with three 3/8" T-Slots. I'm wondering if there is a certain size of Mill Vise that I should be looking into? I don't want to buy the wrong Vise that I will find to small or to big once I try using it.
