ABSTRACT

A vacuum vice for holding a bowling ball when drilling holes or engraving the
ball includes inner and outer o-rings seals which form inner and outer
concentric vacuum chambers that work together to form a seal with a bowling
ball having surface imperfections or engraving. The inner vacuum chamber holds
the ball against the inner seal and a vacuum passageway applies the vacuum to
the outer vacuum chamber which seats the ball against the outer seal.
