ABSTRACT:
A versatile set up assembly for holding a workpiece during a machining operation includes upper and lower plates that can be selectively hingedly connected and/or disconnected along spaced parallel axes of connection, thereby permitting either end of the upper plate to be hingedly raised with respect to the lower plate, or the upper plate removed entirely. Two rolls are rotatably mounted to one of the plates along two spaced, parallel axes. The other plate has two pairs of connectors, each pair axially aligned with and adapted to precisely engage the outer ends of one off the rolls along an axis of connection. When the aligned connectors are moved into engagement with the respective ends of a roll, precisely machined surfaces of the connectors and the outer ends coact to ensure the forming of an accurate and repeatable hingable connection between the plates along the axis of connection.
