Using Auxiliary Wood Facing on RIP Fence

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. 35. The PUSH STICK can easily be made from scrap material as explained in the section “CONSTRUCTING PUSH STICK.” When ripping stock 2 inches or narrower, assemble an auxiliary wood facing to the fence, as explained in the section “USING AUXILIARY WOOD FACING ON RIP FENCE” and use a PUSH STICK.

USING AUXILIARY WOOD FACING ON RIP FENCE

It is necessary when performing some special operations to add wood facing (A) Fig. 36, to one or both sides of the rip fence, as shown. The wood facing is attached to the fence with wood screws through the holes in the fence.

A wood facing should be used when ripping material such as thin paneling to prevent the material from catching between the bottom of the rip fence and the saw table surface.

USING ACCESSORY

DADO HEAD

WARNING: DO NOT USE A “WOBBLE” DADO BLADE, OR A DADO BLADE LARGER THAN 6" DIAMETER.

IMPORTANT: THE BLADE GUARD AND SPREADER ASSEMBLY CANNOT BE USED WHEN DADOING, AND MUST BE REMOVED.

Dadoing is cutting a rabbet or wide groove into the work. Most dado head sets are made up of two outside saws and four or five inside cutters, as shown in Fig. 37. 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, as shown in Fig.

38.The saw and cutter overlap is shown in Fig. 39, (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.
