wide enough to give clearance for the cutters. This allows unnecessary exposure of the cutters, the cutter block
and the spindle, and in addition the leading end of the workpiece may foul the edge of the take-off half of the
fence. These risks are eliminated by the use of a false fence or by a suitable proprietary alternative which fills
the gap between the fences. Care shall 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 cutter by hand.
10. Stopped work
Straight work where the cut extends over part of the length of the workpiece.
Work of this nature is usually referred to as stopped work. The cutters have to break into the solid face,
instead of starting the cut at the beginning of the workpiece, and/or have to break out before reaching the end.
Unless the workpiece is large enough to protects the cutters as far as practicable. A solidly fixed back and/or
front stop shall also be used.
The jig shall permit the workpiece to be located quickly and accurately and to be held firmly in position.
The most convenient means of holding the workpiece is to use manually operated quick acting clamps which
operate with either a toggle or a cam action. Back and/or front stops fixed to the fence or table allow for
greater control of the jig and a lead in and out may be provided by means of a template on the jig.
