(iii) Now screw the Disc Sander onto the spindle and,
using the same angle adjustments as when a
sawblade is mounted, position the sanding disc at the
angle required.
If the sanding operation requires movement of the
yoke assembly (as in a bevel or straight crosscut
position), make sure the material is held firmly on the
table.
If the operation requires the movement of the
material past the disc, then the material must be held
firmly in both hands, while the yoke assembly is
locked on the arm by the rip lock.
When using the Disc Sander as a sanding table (Fig.
50) you may find it easier to clamp a faJse table
alongside it to support your material higher up
against the disc.
Always use the downward (right-hand) side of the
disc, otherwise you will find it difficult to hold the
material steady.
In most sanding positions a guard is unnecessary.
However, when using the disc for horizontal
sanding (Fig. 51), the Shaping Head guard should
be mounted and adjusted up so that the sanding
disc is just clear of the underside of the guard.
When removing the Disc Sander you will find it
necessary to hold the motor shaft steady with the
alien key supplied with the machine.
The optional Drum Sander enables easy, accurate sanding
of contours and irregular shapes (Figs. 52/1 ), wht
otherwise can only be sanded by hand.
The Drum Sander screws directly onto the motor spindle,
with the sawblade flanges mounted in the same way as for
the disc sander above (Fig. 54).
The height and angle of the Drum Sander can be altered
in the same way as with other attachments (Fig. I
No guard is necessary.
When using the Drum Sander vertically you may find it
advantageous to remove the fence and/or the rear table
strips, thereby allowing plenty of space for your material to
be moved around the Sander.
Always feed your material against the rotation of the
Drum Sander.
By mounting the optional Sabre Saw attachment on the
motor spindle in place of the sawblade. you can turn your
machine into a radial sabre - or jigsawing machine.
(i) First mount the special back spacer onto the spindle
(Fig. 56) and then stabilise the sabre saw attachment
on the shaft with the steady struts locating on the
special lugs in the motor housing.
(ii) Finally, use the standard arbor nut to secure the
attachment on the shaft.
You can then position the sabre sawblade depending
on the requirements of the job. In most (Fig. 57)
cases the best position will be as with the Drum
Sander above:-
— remove the table fence and substitute it with wooden
spacers 20mm thick and then position the blade (teeth
forwards) just behind the front table section (Fig. 58)
and low enough so that the shoe of the attachment will
slide across the upper surface of the material being cut.
