ABSTRACT:
A portable, in-situ, omni-directional orientable assembly for refurbishing a bore in a workpiece and including a cutting bar with various tool holding options, a main jig assembly for effecting azimuthal alignment, rotation and translation of the cutting bar and various journaling options, including non-journaled operation. The cutting bar is an elongate rigid bar which has multiple chambers for holding cutting tools in addition to a removeable, toroidal tool holding adjunct that is slidable on the cutting bar and lockable to the bar by the insertion of a key into mutual longitudinal keyways provided in the cutting bar and the toroidal tool holding adjunct. A main jig holding rotary drive means provides omni-directional alignment capability and adaptability for transferring the rotary motion, as well as translational motion, to the cutting bar. The cutting bar may or may not be journaled; but if journaling of the bar is desired, a portable pillow block assembly is provided. The pillow block is detachable from its portable jig assembly and may be used independently, and in plurality, as the means for journaling the cutting bar.
