A workpiece supporting assembly for securing an elbow during a machining process that is performed on the elbow by operation of a workpiece machining implement, the workpiece supporting assembly comprising: a body having an internal surface defining a channel, the internal surface sized to receive a medial portion of the elbow when the elbow is operably disposed in the channel; and a support that is selectively positionable to secure the elbow in the workpiece supporting assembly, the body pivotable to a first pivoted position, the body sized so that a first end of the elbow extends from the channel and beyond the body so the first end of the elbow is presentable to the workpiece machining implement for performing the machining process, the body pivotable to a second position and sized so that a second end of the elbow extends from the channel beyond the body so the second end of the elbow is presentable to the workpiece machining implement for performing the machining process. view more

The workpiece supporting assembly of claim 14 wherein the support comprises an adjustment bolt supported by the housing member to extend into the workpiece channel.

A workpiece supporting assembly for rigidly supporting an elbow during a machining process that is performed on the elbow by a workpiece machining implement, the workpiece supporting assembly comprising: a body having an internal surface defining a channel, the internal surface sized to receive a medial portion of the elbow when the elbow is operably disposed in the channel; and a support adjustment bolt threadingly engaged with the body and selectively positionable to urge the medial portion of the elbow against the internal surface, the body sized so that each end of the elbow extends from the channel and beyond the body so that each end of the elbow is presentable to the workpiece machining implement for performing the machining process after securing the elbow and before removing the secured elbow from the workpiece supporting assembly. view more

A workpiece supporting assembly for securing an elbow during a machining process that is performed on the elbow by operation of a workpiece machining implement, the workpiece supporting assembly comprising: a body having an internal surface defining a channel, the internal surface sized to receive a medial portion of the elbow when the elbow is operably disposed in the channel; and a support that is selectively positionable to operably urge the medial portion of the elbow against the internal surface to thereby secure the elbow in the workpiece supporting assembly, the body selectively positionable to a first position where a datum axis of one end of the secured elbow is operably aligned with the workpiece machining implement, and the body alternatively positionable to a different second position where a datum axis of the other end of the secured elbow is operably aligned with the workpiece machining implement. view more

A method for securing an elbow during a machining process that is performed on the elbow by operation of a workpiece machining implement, the method comprising: obtaining a workpiece supporting assembly having an internal surface defining a channel, the internal surface sized to receive a medial portion of the elbow; placing the elbow in the channel; positioning a support to operably secure the elbow in the workpiece supporting assembly, the body sized so that each end of the elbow extends from the channel and beyond the body so that each end of the elbow is presentable to the workpiece machining implement for performing the machining process; after the positioning a support, positioning the workpiece supporting assembly to a first position to align a datum axis of one end of the elbow with the workpiece machining implement and performing the machining process for the one end of the elbow; after the positioning the workpiece supporting assembly to a first position, positioning the workpiece supporting assembly to a different second position to align a datum axis of the other end of the elbow with the workpiece machining implement and performing the machining process for the other end of the elbow; and after the performing the machining process for the other end of the elbow, removing the secured elbow from the workpiece supporting assembly. view more

A method for machining an elbow having first and second ends, comprising: placing the elbow into a channel on a body of a workpiece supporting assembly so that first and second ends of the elbow extend beyond the channel; securing the elbow against at least a portion of an inner surface of the channel using a support that engages the body; performing a first machining operation on the first end of the elbow; positioning at least a portion of the workpiece supporting assembly; performing a second machining operation on the second end of the elbow; and removing the elbow from the workpiece supporting assembly. view more

A workpiece supporting assembly for securing an elbow during machining of first and second ends of the elbow by a workpiece machining implement, comprising: a body having a channel therein for receiving the elbow, whereby the first and second ends of the elbow extend from the channel; a support that engages the body and secures the elbow in the channel, the body positionable between a first position for machining the first end of the elbow by the workpiece machining implement and a second position for machining the second end of the elbow by the workpiece machining implement. view more
