ABSTRACT:
A work holder support apparatus includes an elongate support member having an undercut longitudinal slot. A base plate at one side of the support member carries a spherical ball and a clamp bolt seated in a recessed bore in the ball passes through the base plate and slot to be threadably received in a first clamp plate at the opposite side of the support member. An elongate work holder mounting member and a second clamp plate cooperatively define a ball receiving socket at one end of the mounting member enabling the mounting member to be clamped at any of a wide range of rotative adjustments relative to the ball. An opening into the socket affords access to the recessed clamping bolt head.
