11.9 Circle Cutting
(Fig. 38)
Although a circular saw is normally thought of as only able
to make straight cuts, cutting perfect circles is also quite
straightforward on your radial arm saw using only the
standard circular saw blade.
Cramp a false table to the main one, or substitute a strip
as thick as the table itself in place of the fence. Use a
woodscrew as a pin and screw this part way into the
chosen aid, and then saw the head off. Make a hole in the
underside of the wood, from which the circle is to be
formed, and then fit to the pin. Lower the blade just clear
of the wood, and lock the carriage at a tangent to the
proposed circular cut. Hold the wood firmly and lower the
arm by half a turn. Then using both hands rotate the wood
on the pin in a clockwise direction against the blade. After
each revolution lower the arm by half a turn until all the
waste is cut away, and the circular piece is formed.

12. OPERATION OF THE MACHINE WITH OPTIONAL ATTACHMENTS AND
ACCESSORIES
Even in its standard form with the basic general purpose
sawblade, the Powershop is already more versatile than
any other type of sawing system.
The range of optional attachments, however, add a further
dimension to your woodworking potential. They will turn
your Powershop into a complete workshop.
You will find the optional TCT saw blades prove
advantageous, particularly when cutting hardwoods and
man-made materials. TCT blades require less frequent
'sharpening and have a much longer life than ordinary steel
blades.
Note: Never use blades larger than 250mm diameter —
an imperial 10" blade measures 254mm diameter
and is therefore too large.
Before mounting or changing any attachments or
accessories, disconnect your Powershop from the
mains power supply.
12.1 Shaping/
Moulding
Adding that professional finish to your work with a clean
decorative edge is quick and easy with the optional
DeWalt Shaping Head attachment (Fig. 39). It can also be
used for cutting round grooves and for drawer, and tongue
and groove joints. The range of cutter profiles available is
illustrated in the list at the back of this booklet.
The DeWalt Shaping/Moulding Head is mounted on the
motor arbor as follows:
(i)
Remove the saw blade guard, arbor nut, blade
flanges and saw blade.
(ii)
Mount the special back flange(s) (supplied with the
Shaping Head) onto the motor arbor.
(iii)
Now put the Shaping Head on the motor shaft with
the recessed centre facing outwards and then lock it
into position with the special clamping nut, using the
special box spanner (Fig. 40).
(iv)
Fit the required pair of shaping knives in the Head or
Block carefully setting them so they both protrude to
the same extent beyond the outside edge of the
Block itself.
