1.You can easily attach a moulding cutterhead (A) Fig. 59 to the saw arbor. Also, you must use the accessory moulding cutterhead table insert (B) in place of the standard table insert.

2.When using the moulding cutterhead, add wood-facing (C) to the face of the rip fence (Fig. 60). The wood-facing is attached to the fence with wood screws through holes which must be drilled in the fence. Stock that is 3/4" inch thick is suitable for most work, although an occasional job may require 1" facing.

3.Position the wood-facing over the cutterhead with the cutterhead below the surface of the table. Turn the saw on and raise the cutterhead. The cutterhead will cut its own groove in the wood-facing. Fig. 60 shows a typical moulding operation.

Never use a moulding cutterhead in a bevel position.

Never run the stock between the fence and the moulding cutterhead. Irregular-shaped wood will cause kickback.

Give special attention to the grain direction. Make all cuts in the same direction as the grain whenever possible.

Always install the blade guard after the operation is complete.

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. 61).

 

 

 

 

 

 

 

 

 

 

 

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. 61). The

 

 

 

 

 

 

 

 

 

 

 

saw and cutter overlap is shown in Fig. 62 - (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

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 operation is complete.

NOTE: Fig. 65 illustrates a typical dado operation.
