Chuck Vise

This is a vise base I designed to hold a smallrig clamp or any clamp with accepts a 1/4x20 bolt. There are 3 bases: regular, small, and pana. The pana base has a hole pattern to match a pana vise. There are 2 nuts: regular and wing style. The balls are 3 different heights. The two smaller balls use 2" long bolts and the third uses a 2.5" long bolt.
