Bevel Ripping - Delta RT-40 Manual De Instrucciones

BEVEL RIPPINg

Bevel ripping (Fig. 63) is the same as ripping except the
bevel angle is set to an angle other than 0°.
When possible, place the fence on the right
side of the blade so that the blade is tilted away from
the fence and hands. keep your hands clear of the blade
and use a pushstick to feed the workpiece if there is less
than 6" between the fence and the blade.
Use caution when starting the cut to prevent
binding of the guard against the workpiece.
USINg AN ACCESSORY dAdO HEAd
The blade guard and splitter assembly cannot
be used when dadoing or moulding. It must be removed
as described in "USINg AN ACCESSORY MOULdINg
CUTTERHEAd" section.
Use pushsticks, hold-downs, jigs, fixtures,
or featherboards to help guide and control the workpiece
when the guard cannot be used.
You must make your own table insert (throat
plate) to use when cutting dados. The standard table insert will
not work with dado cutters.
Dadoing is cutting a rabbet or wide groove into the workpiece.
Most dado head sets are made up of two outside saws and
four or five inside cutters, (Fig. 64). Various combinations of
saws and cutters are used to cut grooves from 1/8" to 13/16"
for use in shelving, making joints, tenoning, grooving, etc. The
cutters are heavily swaged and must be arranged so that the
teeth do not hit each other during rotation. The heavy portion
of the cutters should fall in the gullets of the outside saws (Fig.
65). The saw and cutter overlap is shown in Fig. 66 - (A) being
the outside saw, (B) an inside cutter, and (C) a paper washer or
washers, used as needed to control the exact width of groove.
A 1/4"groove is cut by using the two outside saws. Position the
teeth of the saws so that the raker on one saw is beside the
cutting teeth on the other saw.
do not attempt to stack dado blades thicker
than 13/16" (20mm) do not use dado blades larger than 12"
(305 mm) in diameter. Also, your accessory dado set must
have a 1" arbor hole.
Attach the dado head set (D) Fig. 67 to the saw arbor.
NOTE: If the arbor nut does not fully engage the thread on the
arbor, remove the outside arbor flange and tighten the arbor nut
against the dado head set body. Do not lose the outside arbor
flange. It will be needed when reattaching a blade to the arbor.
Never use the dado head in a bevel position.
Always install the blade guard and standard
table insert after the dado operation is complete.
A typical dado operation is illustrated in Fig. 68
