Chapter 5, Operating Instructions: Mounting the Mandrel on the Pipe
E.H. Wachs Part No. 81-MAN-00, Rev. 0-0610 35
A socket wrench and 1-1/16”
socket are provided with the
EP 424.
5.
Using a 1-1/16” wrench or socket, turn the drawbar
nut counter-clockwise to retract the clamping legs.
Figure 5-4. Turn the drawbar nut counter-clockwise
to retract the clamping legs.
For stability, the clamp legs
should be as close as possi-
ble to the end of the pipe.
However, make sure they are
far enough into the pipe to
avoid being damaged during
the operation.
This is espe-
cially critical if you are
counterboring.
6.
Insert the clamping legs into the I.D. of the pipe. Hold
the mandrel so that the legs are far enough inside the
end of the pipe to be out of the way of the machining
operation.
Figure 5-5. Insert the clamping legs into the pipe.
7.
Turn the drawbar nut clockwise to clamp the legs
inside the pipe until they are snug enough to hold the
mandrel.
