>You need a vac gauge. You'll get to know what kinds of pressures things can and cannot take. Snugging/centering a piece of work requires light pressure, then when you finally get it, crank it up. Thin walled work needs lighter pressure, etc..
You at least need some way to "gauge" how much pressure is being applied to the outside of your turnings (thats how the vacs work - air pressure pushes them onto the drum). Whether it be in a hand crank that you get to know well, or an actual gauge is up to you.
