摘要:
A boring tool for repairing brake spiders in place on a vehicle axle. The tool having a base rotatably mountable on the axle spindle with adapter means permitting tool use on various spindle configurations. Elongate bearing sleeves radially spaced from the base are adapted for rotation into axial alignment with the anchor pin bores of the brake spider. A retention bar and a boring bar interchangeably journalled in said sleeves respectively position the tool. Rotation of the base subsequent to a first boring operation permits bar extraction and interchange prior to a second boring operation. Additional structure is shown providing feed means for the boring bar. A modified form of the invention permits permanent retention of retention and boring bars within their respective sleeves.

A sleeve sized for cooperatively surrounding the free end of a conduit is adjustably secured thereto by a setscrew. A tubular template cutter, having a sharpened end, is coaxially received by the free end of the sleeve and is rigidly secured therein by a bolt so that when template forming material is forced against the cutter the cutter forms a hole in the template material coaxial with respect to the conduit.
