USING AUXILIARY WOODFACING ON
RIP FENCE
Wood facings (A) Fig. 53A are necessary on some special
operations to one or both sides of the rip fence. The wood
facing is attached to the fence with screws through the
holes in the fence. Most work will require a 3/4 " stock,
although an occasional job may require 1" facing.
ACCESSORY DADO CUTTERHEAD
NOTE: THE MAXIMUM WIDTH DADO CUT FOR THIS
SAW IS 1/2 INCH.
THE BLADE GUARD AND SPLITTER
ASSEMBLY CANNOT BE USED WHEN DADOING. IT
MUST BE REMOVED.
Before dadoing, loosen wing nut (A) Fig. 54 and take
off the blade guard and splitter assembly (B). Keep
assembly handy to replace it after dadoing.
1. 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, (Fig. 54A). 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.
55. The saw and cutter overlap is shown in Fig. 56, (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. The teeth of the saws should be
positioned so that the raker on one saw is beside the
cutting teeth on the other saw.
