9.8 Face plate: installing/removing
1.
Disconnect Lathe from power source.
2.
Mount the face plate to your bowl blank.
3.
Push in the spindle lock button (Figure 20) and
rotate the handwheel slightly until the spindle
locks. Keep the spindle lock button pushed in.
4.
Install the face plate onto the threads of the
headstock spindle and rotate clockwise hand-
tight. When the Lathe is turned on (forward
rotation), the rotational force will snug the face
plate even farther onto the threads.
If at any time you will be
reversing spindle rotation, make sure the two
set screws in the face plate are tight! One of
these is shown in Figure 21. Failure to do this
may cause the face plate to loosen from the
headstock spindle.
5.
To remove the face plate, loosen the two
socket set screws (Figure 21). Engage the
spindle lock button and turn the face plate
counterclockwise with the face plate wrench,
as shown in Figure 21.

9.9 Speed change
1.
Disconnect Lathe from power source.
2.
To change speed ranges, pull open the access
door on the headstock.
3.
Loosen the pivot lock handle (A, Figure 22)
and lift up the tension handle (B, Figure 22) to
raise the motor. Tighten the pivot lock handle
(A, Figure 22) to hold the motor in the raised
position.
4.
There should be sufficient slack in the belt to
reposition it to the other steps on the sheaves.
The label on the access door shows the
required belt position.
5.
Loosen the pivot lock handle (A, Figure 22)
and lower the motor to tension the belt. Be
sure that the Poly-V grooves of the belt seat
properly in the corresponding groove of the
sheave. Do not overtension; a very light
pressure on the tension handle (B, Figure 22)
is adequate to prevent belt slippage.
6.
Tighten the pivot lock handle (A, Figure 22).
9.10 Sheave and belt alignment
The motor and spindle sheaves are aligned with
each other at the factory, but if any service is
performed that affects their alignment it is very
important that they be realigned. To realign them,
loosen the two set screws on the spindle sheave
(C, Figure 22) with a hex wrench, and slide the
spindle sheave into the proper position. Re-tighten
set screws.
When sheaves and belt are properly aligned, there
should be no unusual pulsing sounds or noise
coming from the belt.
