When ripping boards longer than three feet, it is recommended that a work support be used at the rear of the saw to keep the workpiece from falling off the saw table.
If the ripped work is less than 4 inches wide, a push stick should always be used to complete the feed, as shown in Fig. 60. The push stick can easily be made from scrap material as explained in the section “CONSTRUCTING A PUSH STICK.” 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. That flat pushboard can be made as shown in Fig. 61.
USING AUXILIARY WOOD FACING ON BIESEMEYER RIP FENCE
It is necessary when performing special operations such as moulding to add wood facing (A) Fig. 62, to one or both sides of the rip fence, as shown. The wood facing is attached to the fence with two clamps (B). 3/4 inch stock is suitable for most work although an occasional job may require 1 inch facing.
A wood facing should be used when ripping thin material such as paneling to prevent the material from catching between the bottom of the rip fence and the saw table surface.
USING AUXILIARY WOOD FACING ON THE UNIFENCE
It is necessary when performing special operations such as when using the moulding cutterhead to add wood facing (A) Fig. 63, to one side of the rip fence as shown. The wood facing is attached to the fence with wood screws through holes you drill in the fence. A suitable stock size for most work is 3/4", although an occasional job may require one inch facing.
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. 64. 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.
