The carriage has power feed capability when it
is engaged with the lead screw. The rate that the
carriage moves (feed rate) is controlled by V-belt,
change gear, and gearbox dial configurations.
Feed rate and spindle speed must be considered
together when determining the proper cutting
speed for a given workpiece. The sources you
use to determine the optimum spindle speed for
an operation will also provide the optimal feed rate
to use with that spindle speed.
Often, the experienced machinist will use the
feeds and speeds given in their reference charts
or web calculators as a starting point, then make
minor adjustments to the feed rate (and some-
times spindle speed) to achieve the best results.
The carriage can alternately be driven by the
leadscrew for threading operations. However, this
section only covers using the power feed option
for the carriage for non-threading operations. To
learn how to power the carriage for threading
operations, refer to
Threading on Page 46.

Follow along with this example for setting the
spindle speed for the Model G0752 to gain a bet-
ter understanding of this task.
To set the spindle speed to 150 RPM:
1. DISCONNECT LATHE FROM POWER!
2. Open the change gear cover, use an 8mm
hex wrench to loosen the tensioner bolt, then
move the tensioner out of the way.
3. Move the V-belt to the outer pulley sheaves
to select the low speed range (100-800
RPM), as shown in
Figure 59.
4. Re-tension the belt (refer to "Tensioning
V-Belt" on Page 63) and secure the tension-
er.
5. Turn the spindle direction switch to FWD, and
press the ON button.
6. Adjust the spindle speed dial until the spindle
speed display reads 150 RPM.
