Using Accessory Moulding Cutterhead

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. 125. 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.

IMPORTANT: For certain cutting operations such as dadoing and moulding where you are not cutting completely through the workpiece, the blade guard and splitter assembly cannot be used. Loosen screws (G) and

(H)Fig. 126. Lift up and swing blade guard and splitter assembly (W) Fig. 127, to the rear of the saw, and then tighten screws (G) and (H). CAUTION: Always return and fasten the blade guard and splitter assembly to its proper operating position for normal thru-sawing operations.

The moulding cutterhead (A) Fig. 128, is assembled to the saw arbor as shown. NOTE: THE OUTSIDE ARBOR

FLANGE CAN NOT BE USED WITH THE MOULDING CUTTERHEAD, TIGHTEN THE ARBOR NUT AGAINST THE CUTTERHEAD BODY. DO NOT LOOSE THE OUTSIDE ARBOR FLANGE, FOR IT WILL BE NEEDED WHEN REATTACHING A BLADE TO THE UNISAW ARBOR. ALSO, THE ACCESSORY MOULDING CUTTERHEAD TABLE INSERT (B), 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. 129. The wood-facing is attached to the biesemeyer fence with two clamps, as shown (refer to the Unifence section of this manual for attaching wood facing to a Unifence). 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. 129, shows a typical moulding operation. NEVER USE MOULDING CUTTER-

HEAD IN A BEVEL POSITION.

IMPORTANT: NEVER RUN THE STOCK BETWEEN THE FENCE AND THE MOULDING CUTTERHEAD AS IRRE- GULAR 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 the grain, making the cut in the same direction as the grain whenever possible.

ALWAYS INSTALL BLADE GUARD AFTER OPERATION IS COMPETE.
