gauge are touching the end of the pipe. Re-tighten the
legs to hold the chuck body in place.
Figure 5-16. Push the chuck body into the pipe until
all four arms of the alignment gauge are against the
pipe surface.
You will roughly center the
chuck body in the pipe (to the
precision of the alignment
gauge scales). You will pre-
cisely center the mandrel
later in this procedure.

To center the chuck body, refer to the scales on the
alignment gauges. Using a 1-1/8” end wrench on the
flats of the chuck legs, turn opposite legs in or out
until the scale touches the pipe I.D. at the same dis-
tance on both sides.
Figure 5-17. Alternately adjust opposite legs to center
the chuck in the pipe.

When the chuck body is centered, use a 2-1/4” wrench
to snug the jam nuts against the chuck body.
