Also see page 8. FO R GROOVES, RABBETS, CHAMFERS Use a dado set or an adjustable da<;lo. FOR CUTTING TRUE DADO TENONS Use the universal jig for exact positioning and holding of . workpiece. FOR EDGE MOLDING, CUTTING TONGUE-AND-GROOVE JOINTS AND DECORATING Use either the single- or triple-cutter molding head . . . You also need the hold-down attachment (to attach to an auxiliary, homemade fence) and/or the universal jig. FOR CUTTING EX ACT MEASUREMENT TAPERS Use the adjustable taper jig. FOR SANDING EDGES AT TRUE MITER AND/OR BEVEL ANGLES Use a sanding wheet . with tw o different grit discs cemented to its two faces. FOR ACCURATE, EASIER CROSSCUTTING Use a hold-down on your miter gauge . [. . . ] The two mitered strips should be cut at the same time , with the miter gauge set at 450 · Guide strips underneath are to slide in the miter-gauge grooves . Workpieces should be square cut to the desired over-all length plus 1/4 in . to allow for saw kerfs, and are then miter cut in the jig. USE GUARD AND SPLITTER WHENEVER POSSIBLE 17 THE DADO HEAD SET NEW ADJUSTABLE SATIN-CUT HEAVY-DUTY ' & , I , ;' "~ . . . The Dado Head Set-Up HOW A DADO HEAD WORKS A Typical Head Set A dado insert (p. Dado blades are generally smaller in diameter than standard saw blades . Each setting of the dado head must be made by aligning the top of the blades with a mark on the work. Unless they are positioned in the gullets of adjacent outSide blades, and staggered with r espect to other adjacent chipper teeth, they will hold the blades apart so that a true width of cut cannot be determined. OU TSIDE BLADE CHIPPER BLADE The dado saw (or head) is a specia l set of blade s for cutting grooves and c1ados. This head consists of two full-circle outside blade s and a number of two - toothed chipper blade s for use between the outside blades. (2 outside blades and the small chipper) ·. · and in additional wiclths in increments of 1/ 16 in. The out side blades cut in the same manner as a combination blade ; the chipper blades act as planers to s mooth out the area between the two outside bla des . Chipperscmmolbeused alone as they will tear the work. Fractional Thickness Adjustments Fractional adjustments in the thickness of a dado head can be made by using papewashers to separate the outside blades frOlL j the chippers. Such adjustments are often useful in sec uring a tight fit for a grooved joint.

Simply by "dialing" the hub - prior to tightening blade on s aw arbo r - groove widths from 1/ 4 to 13/ 16- in. can be set. USING A STOP BLOCK HANDLING WORKPIECES Operations with a dado are much the same as with a standard blade. It must be remembered, however, that a dado takes a bigger bite in the workpiece; and that the likelihood of kickback is therefore increased. As the splitter, and consequently the anti-kickback pawls, cannot be used, the workpiece should be held down firmly by hand, or by use of the hO l d- down attachment When moving the workpiece over to make additional cuts, move it just a little less than the thickness of the dado so that the cuts will overlap. Also remember that right side of dado will establi sh right-edge cut, and the left s ide of the dado will establish left-edge cut. GAINS AND STOPPED GROOVES IP. 4). REGULARLY SPACED GROOVES A gain is a groove that is closed at one end; stopped grooves a re c losed at both ends. Both are used in making jOints. Regular spacing of grooves can be done by using the s top rod on the miter gauge to en I. ge the last- cut groove. Another method ~ to use a notched stop block to fix the starting positions. This block should be clamped to the table well ahead of the blade so that work is free from it before cutting operation begins . The block can be notched in regular steps, or according to any desired pattern. A third method is to clamp a yardstick to the miter gauge (or miter-gauge extens ion), and position the work for any desired spacing of grooves by referring to the inch marks on the s tick. A gain is started like an ordinary groove, but a stop block is used to fix the end of the cut. [. . . ] DON'T ABUSE CORD Never carry tool by cord or ya nk it to disconnect from receptacl e. KEEP GUARDS IN PLACE and in working order. 13. SECURE WOR K Use clamps o r a v ise to hold work : It's safer than using y our hand a nd it frees both hands to operate tool. 4. KEEP WORK AREA CLEAN Cluttered areas and benches inv ite accidents. 14. DON'T OVERREACH Keep proper footing and balance at all t imes. 5. [. . . ]
