Found a trick for squaring vises that actually sticks

Been fighting with my vise moving during heavy cuts for months. Tried all the usual stuff, torque wrench, cleaning, nothing held. Buddy at work showed me to use a deadblow hammer on the vise base after tightening. Three light taps and it sat perfectly square. Ran a full 6 hour cycle on a steel part yesterday, no movement at all. Anyone else use this method or am I late to the party?

Did you check if the hammer knocked it out of square before you torqued it down, or did you tap after the final tighten?

Man that deadblow trick is the real deal. I started doing it a couple years back after watching this old timer on a job site and felt like an idiot for not figuring it out sooner. I had this one job where I was blowing through stainless parts and my vise would creep no matter what I did. Three taps with a deadblow on each corner after snugging it down and it stayed put through the whole run. I even started keeping a deadblow right next to my vise instead of in the toolbox because I use it that much.
