forth in more detail in fig2 and 3 however with reference again to fig1 jig assembly 2 includes in addition to the reforming apparatus 3 a power tong 4 of conventional design and which functions to hold the workpiece or drill pipe 5 in a stationary position when the reforming machine 3 is is operation a pipe rack 6 is provided adjacent jig 2 and includes a set of rollers 7 for revolving workpiece 5 when the workpiece 5 is being connected and disconnected from the reforming machine 3 a power driven tightening and untightening wheel 8 is included on pipe rack 6 and functions to assemble and disassemble the workpiece 5 from the reforming apparatus 3 in overall operation and viewing again fig1 pipe rack 6 is loaded with several workpieces or drill pipes 5 that have been damaged in use and require reforming to remove crimps or crushed areas from the wall thereof a single pipe 5 is moved to rollers 7 and forced axially onto reforming machine 3 wheel 8 moves into engagement with pipe 5 and tightens pipe 5 onto reforming apparaus 3 the power tong 4 is then actuated to grip pipe 5 in a stationary fashion and then the reforming apparatus is energized to perform its intended function after the pipe 5 has been reformed or reshaped by apparatus 3 power tongs 4 are released wheel 8 is again moved into position adjacent pipe 5 and the pipe is disconnected.
