CAUTION:
Position the Spacers flush with the inside face of the Tool Holder.
Tool Bits B and C should be the same distance inward from the tool Holder.
Tighten the Set Screws holding Tool Bits B and C.
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.
Rotate the Feed Sprocket until Tool Bit A allows .006" (.2 mm) minimum
clearance between Tool Bit A makes contact with the pipe.
Back the Tool Holder away from the pipe about 1/4 of a revolution,
approximately .008” (.2 mm).
Each full revolution of the Feed Sprocket moves the Tool Bit .031” (.8 mm)
toward or from the pipe.
Continue to rotate the Headstock through 360 o slowly, in order to verify that
the position of 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.
Position Tool Bits B and C directly over the mark that you made to define the
closest approach of Tool Bit A to the pipe.
Rotate the Feed Sprocket until Tool Bits B and C make contact with the pipe
surface.
Back the Tool Holder off 1/4 revolution of the Feed Sprocket, approximately
.008” (.2 mm), plus the desired land width.
