ABSTRACT:
Pin bores of excavator forebooms are subjected to impact and side loading, causing wear which eventually leads to wobble of the foreboom. The close tolerance required in reboring such bores has previously necessitated transporting the foreboom to repair shops with large machine tools and jigging capacity for such massive structures. The present invention provides a fixture embodiment (30) adapted to rebore a workpiece (10), such as a foreboom, to within close tolerances in conjunction with an easily portable powered drill or the like. Reboring operations may be performed at any convenient site. Fixture embodiment (30) comprises a guide member (32), a structure (40) for holding the guide member (32) to the workpiece (10) in a precisely positioned relationship, a boring bar (52) and a supporting and aligning structure (70). A method for reboring the workpiece (10) is also disclosed.
