CAUTION:
Set Tool Bit A to lead Tool Bit B and C by the desired land width as follows:
Make sure that the Tripper Shaft is in the ‘out’ position.
Rotate the Headstock slowly.
While rotating the Headstock, visually determine the point on the surface where Tool
Bit A comes closest to the pipe.
Tool Bit Set Up
Rotate the Feed Sprocket until Tool Bit A makes contact with the pipe.
Back the Tool Holder away from the pipe about 1/4 of a revolution. (approximately
.008”)(.20 mm).
Each full revolution of the Feed Sprocket moves the Tool Bit .031” (.78 mm) toward
or away from the pipe.
Continue to rotate the Headstock through 360 O slowly, in order to verify that the
position of Tool Bit A allows .006” (.15 mm) minimum clearance between Tool Bit A
and the pipe surface at the closest point.
Readjust Tool Bit A if necessary.
Mark the pipe surface to define Tool Bit A’s closest approach to the pipe.
Continue to rotate the Headstock slowly.
