THE HEADSTOCK
The headstock includes a Gear box (E) which con-
tains gears and a belt drive. The gears are con-
trolled by controls (F), (G), and (H). The belt drive
transmits the motor power to the drive system of the
machine.
The motor and drive belt are installed and ad-
justed when delivered. However, you should
check the adjustment of the drive belt before
using this lathe.
Check the belt tension by pressing in the middle
with your finger. You should be able to depress
it approximately 1/2 inch. If the belt is too tight,
it will wear the bearings, and if too loose, it will
slip on the pulleys and wear out prematurely.
If it is necessary to adjust the belt tension, do so
by adjusting the bolt and locknut assembly on
the underside of the motor. The motor mounted
on the back of the headstock.
Four additional change gears are included for
use in cutting metric and SAE threads. Refer
to the lead screw chart on the headstock for
the gears required for the thread pitches you
want.
Please refer to the section on threading for
more information.
