Yes, use an edwards type vacuum pump, not a vacuum cleaner.
just use some neoprene rubber to cover all the holes in the vacuum table not covered by the part
holding force = no of holes covered by part (area) x vacuum
vaccum pump, even knackered one, will pull 13/14 psi vacuum easy, shop vac may pull 5, and will then overheat because the use the airflow to cool the motor usually
