I ended up running impact gun on my vise right now just to cut time on chaning damn size. But is is sucky optionI have a gerardi double station like you just posted but i moved the center jaw to the back and use it as a single vise. It allows me to hold large parts. Its mounted beside a 12" single gerardi they work very well!! I may move 2 clamps more to the middle from the end after reading that gregormarwick thanks! They replaced 2 kurts, that turning the kurts handle from a 1" part to a 5" part sucked.
