3. Ripping narrow pieces can be dangerous if not done

carefully. Narrow pieces usually cannot be cut with the

guard in position. If the workpiece is short enough, use a

pushboard. When ripping material under 2 inches in

width, a flat pushboard is a valuable accessory since

ordinary type sticks may interfere with the blade guard.

When using a pushboard, the width of the pushboard

must be added to the width of the rip fence position

setting. A flat pushboard can be constructed as shown in

Fig. 63 and should be used as shown in Fig. 64.

USING ACCESSORY

MOULDING CUTTERHEAD

Moulding is cutting a shape on the edge or face of the

work. Cutting mouldings with a moulding cutterhead in

the circular saw is a fast, safe and clean operation.The

many different knife shapes available make it possible for

the operator to produce almost any kind of mouldings,

such as various styles of corner moulds, picture frames,

table edges, etc.

The moulding head consists of a cutterhead in which can

be mounted various shapes of steel knives, as shown in

Fig. 65. Each of the three knives in a set is fitted into a

groove in the cutterhead and securely clamped with a

screw. The knife grooves should be kept free of sawdust

which would prevent the cutter from seating properly.

The moulding cutterhead (A) Fig. 66, is assembled to the

saw arbor in the same manner as the saw blade. The

guard, splitter and anti-kickback finger assembly cannot

be used when moulding and must be removed from the

saw. In place of the guard, auxiliary jigs or fixtures and

push sticks and featherboards should be used. Also, the

accessory moulding cutterhead table insert (B) Fig. 66,

must be used in place of the standard table insert.

It is necessary when using the moulding cutterhead to

add wood-facing (C) to the face of the rip fence, as

shown in Fig. 67. The wood-facing is attached to the fence

with wood screws through holes which must be drilled in

the fence. 3/4 inch stock is suitable for most work

although an occasional job may require 1 inch facing.

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. 67, shows a typical

moulding operation.

WARNING: NEVER RUN THE STOCK BETWEEN

THE FENCE AND THE MOULDING CUTTERHEAD AS

IRREGULAR SHAPED WOOD WILL CAUSE

KICKBACK.

When moulding end grain, the miter gage is used. The

feed should be slowed up at the end of the cut to

prevent splintering.

In all cuts, attention should be given to the grain. Make

the cut in the same direction as the grain whenever

possible.

IMPORTANT: ALWAYS REINSTALL BLADE GUARD

AFTER OPERATION IS COMPLETE.
