most machine operations.
Where extreme accuracy is required, align the
fixture laterally with a dial indicator.
Step 3.
Make certain that the fixture plate is horizontally aligned with
the cross travel of the lathe.
Horizontal alignment, adequate for most
operations, can be achieved by loosening the two fixture plate screws and
positioning the vertical edge of the fixture plate parallel with the side of
main housing. On operations calling for tolerances closer than .001 inch,
align the flange of the fixture plate with a dial indicator.
(2) The fixture is now aligned and ready to perform various machining
operations. The fixture can be rotated about a vertical axis to any angle
by means of the lathe compound without disturbing the vertical alignment.

(1) General.
The same safety precautions should be observed when
