COPYING (MACHINING WITH A JIG)
When using the same procedure on multiple
workpieces, a jig or template can be made to facilitate
the operation:
1. Prepare the jig (A) to accomodate your original
workpiece. See Figure 40.
2. Place the jig (A) against the table ring guide shoul-
der (B).
3. Fasten the new workpiece (C) on the jig (A) with
the clamp (D) and push the assembly past the cutter.
FEEDING STOCK
Stock feeders are available from Powermatic. These
units mount to the shaper table, and will help ensure
smooth, consistent feed of material, as well as keep
hands safely away from the cutterhead.

MAINTENANCE
Periodically clean the inside of the machine of shav-
ings and dust. This will increase machine performance
and extend its life.
Clean the spindle with compressed air.
Do not get oil on the pulleys and belts. If they are
dirty, use paper or a soft rag to clean and dry them.
Never place the v-belt under excessive strain, as this
can overload the motor and damage the bearings,
spindle or belt.
The table surface must be kept clean and free of rust
for best results. Some users prefer a paste wax coat-
ing. Another option is talcum powder applied with a
blackboard eraser rubbed in vigorously once a week;
this will fill casting pores and form a moisture barrier.
This method provides a table top that is slick and al-
lows rust rings to be easily wiped from the surface.
Important also is the fact that talcum powder will not
stain wood or mar finishes as wax pickup does.
Lubrication
Apply a drop of light machine oil occasionally on the
ledge and wall of the table opening to facilitate the
changing of table inserts.
