e. To remove the face plate, loosen the two socket set

screws (Figure 19). Engage the spindle lock button and

turn the face plate counterclockwise with the face plate

wrench, as shown in Figure 18.

16.6.9. Comparator – Installing and Using

The spindle comparator consists of two comparator centers

inserted into the brackets at the back of the Lathe. The

comparator is used to mount a finished, or “reference spindle”

from which measurements can be taken, the measurements

being transferred to the new piece which is being turned.

WARNING: The guard must be removed to use the spindle

comparator. Use caution and wear a face mask when turning

without the guard installed.

a. Remove the guard from the headstock bracket.

b. Install the comparator spur center into the headstock

bracket, by lifting up on the spring pin and inserting the

comparator spur center until its point is about even

with the point of the spur center in the headstock

spindle. See Figure 20. The spring pin in the bracket

should engage one of the holes in the comparator

center at this position.

c. Install the rear comparator center in the tailstock

bracket and tighten the bracket handle. See Figure 21.

d. Mount the spur center with the spindle blank that you

will be turning. Loosen the tailstock locking handle, and

slide the tailstock until the live center is about 1-inch

from the spindle blank, then tighten the locking handle.

Advance the live center using the tailstock handwheel,

until the live center is secured in the spindle blank.

e. Mount the reference spindle between the comparator

centers, as shown in Figure 21.

NOTE: The reference spindle should be mounted last after all

adjustment of the tailstock and ram has been accomplished with

the spindle blank. Likewise, when turning operation is complete,

remove the reference spindle first.
