Dadoing is cutting a rabbet or wide groove into a workpiece.

Most dado head sets are made up of two outside saws and

four or five inside cutters (Fig. 52). 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 this heavy portion falls in the gullets of the outside saws

(Fig. 53).

The saw and cutter overlap is shown in Fig. 54, (A) being the

outside saw, (B) an inside cutter, and (C) a paper washer or

washers which can be used as needed to control the exact

width of groove. A 1/4" groove is cut by using the two

outside saws. The teeth of the saws should be positioned so

that the raker on one saw is beside the cutting teeth on the

other saw.

The dado head set is shown attached to the saw arbor in

Fig. 55.

DO NOT USE the outside arbor flange

with the moulding cutterhead. Tighten

the arbor nut against the cutterhead

body. Keep the arbor flange handy

because you will need it when you re-

attach a blade to the saw arbor. Also, you

must use the accessory moulding

cutterhead table insert (E) Fig. 55 in place

of the standard table insert.

DO NOT USE the blade guard and splitter

assembly when dadoing. Instead, use

auxiliary jigs, fixtures, push sticks and

feather boards.

A typical dado operation using the miter gauge as a guide is

shown in Fig. 56.

Never use the dado head in a bevel

position.

Always install the blade guard after the

operation is complete.
