necessary to fit a different false fence for every job carried out. Care should be taken in the
making of a false fence. It is recommended that the cutter opening shall be made by a
controlled screw adjustment on the fence on to the cutter and not by pushing the fence on
to the cutter by hand.
The following faults in fences can occur and should be checked:
A)
Fences out of alignment. Chippings packed behind the front fence plate and back
fence can cause this.
B)
Fences are parallel but not level with one another. Use the fine adjustment screws to
bring them level.
C)
Fences are not square against the table. Chippings at the base of the fence plate
can cause this.
8.2 The Cutterguard
The yellow hood on top of the horseshoe assembly is designed to enclose the cutting area
just above the workpiece. It is important that this is always secured in position when using the
horseshoe as it provides protection from ejected cuttings or cutters which might be thrown
off the workpiece or cutterblock while in operation.
Check that the hood is securely in position before switching on.
8.3 The Shaw Guards
The Shaw Guards are a valuable aid when machining straight work where the moulding
extends over the full length of the workpiece. They serve the dual-purpose of steadying the
workpiece, preventing vibration which could cause kick-back, and enclosing the cutting
area.
Work of this type is done with the aid of the straight fence, and in most cases the workpieces
are of regular rectangular section throughout their length. The workpieces can, therefore, be
guided in the volume formed between the Table, Shaw Guard, and fence. The vertical and
