Installation
1.
DISCONNECT LATHE FROM POWER!
2.
Mount the back plate on the spindle.
3.
Accurately measure the inside of the back
relief bore on the chuck. This dimension is
critical and should be ± 0.001''.
4.
Face and true the diameter of the back plate.
Make passes across the face until its entire
surface has been cut.
5.
Turn a shoulder that is 0.015'' smaller in
diameter than that of the chuck relief bore.
The shoulder height must also be tall enough
so when the chuck is mounted and is being
aligned, the chuck alignment screws have a
surface to jack against.
