3333Using Dado Blade Set and Dado InsertDadoing is cutting a rabbet or a wide groove into the work.Most dado head sets are made up of two outside blades andfour or five inside cutters, as shown in Fig. 32.Various combination of saws and cutters are used to cutgrooves from 1/8” to 13/16” for use in shelving, making joints,tenoning, grooving, ect.The cutters are heavily swaged and must be arranged so thatthis heavy portion falls in the gullet of the outside blades, asshown in Fig. 33. The saw and cutter overlap (A) being theoutside blade, (B) and inside cutter, and (C) a paper washerwhich can be used as needed to control the exact width ofgroove. A 1/4” groove is cut by using the two outside blades.The teeth of the blades should be positioned so that the rakeron one saw is beside the cutting teeth on the other saw.The dado head set is assembled to the sawarbor in the same manner as the saw blade.The guard splitter and anti-kickback fingerassembly can not be used when dadoingoperations and must be removed from the saw.The included dado head table insert must beused in place of the standard table insert.WARNING: Blades are dangerously sharp. Use extreme caution whenworking with or around the blade. Wear proper safety protection such as heavygloves.WARNING: NEVER use the dado head in a bevel position unless youmake your own dado insert!ALWAYS install blade guard after operation is complete!Fig. 32Fig. 33
