Resawing, Bevel and Miter Cuts | Sears 113.29003 manual

RESAWING

Resowing is the cutting of thick boards into thinner ones_ It is a ripping operatiano See Figure 29. Smalt boards-up to 2½" maximum wldth--can be resawed in one pass; but larger boards up to S" maximum require two passes, one pass along each edge of the board.r When two cuts from opposite edges are required, these should be made to overlap _,_" from the approximate center of the board_ If the first cut is too deep, the kerf will close and bind the saw an the second cut, with danger of kickback° Also, when the kerf closes, the two sides of the cut are na longer parallel to the saw blade, and the saw will cut into them to spoil their appearance_ Keep the same face af the board against the fence when making both cuts.

When cutting boards thicker than 4"° a fence should be used

which extends 3½" above the table topr When cutting boards thicker than 5", cut both sides and finish the cut wlth a hand saw_

BEVEL AND MITER CUTS

Bevel cuts can be made from either a crass-cuttingor ripping position by tilting the blade to the desired angle. Miter cuts

can be made only from a cross-cuttingposition when the blade and radial arm are at some angle other than 90 = to the fence° A bevel miter cut is a cut which is both beveled arid mitered. This cut is made with the blade and radial arm set at the desired miter angle to the fence and then the blade only is tilted with respect ta the table top to the desired beve!

angle. This cut is also referred to as a compound miter, See

Figure 30_

USE OF THE DADO HEAD

The dado saw or head, as it is called, is a special set of blades for cutting grooves and dados_ Craftsman 8" Krom.

edge Dada Set can be purchased at any Sears Retail Store or Mall Order House. The head consistsof two autside blades

I/8" thick, six 1/8" thick chipper blades and Paper wash- ers for'1/t6" width adjustments. With these blades, grooves of 1/8", 1/4", and additional widths increased in steps of 1/t6" up to a maximum of 13/16" wide can be cut. Outside blades con be used alone, chippers cannot°

When using the moxlmum width of dado of 13/16" on

the motor shaft, the outside Ioo_e collar (Item 38, Figure 1) must not be used. The width of the dado can be reduced

while using the loose collar and two or more passes can be made with the work to obtain the desired width of cut°

Whenever two or more chippers are used, stagger the cut- ting ends as evenly as possible around the clrcumference_

Fractlanat adjustments in thickness of the head can be made by using paper washers between the outside blades and chippers° Dado head operations are much the same as those with a standard blade-butthe dado head takes a bigger bite, so that the work-place should be held more firmly. When a groove wider than the dado head is needed, make

two or mare passes_Space cuts so that they oveddp a trifle. Dado work is done in the cross-cut position. Ploughing is done in the ripping position. If the rip or plough position is used the saw guard and anti-kickback pawl assembly should be adjusted as described in the paragraph "RIPPING". Rab- beting is done in the vertical position. See Figure 31. When rabbeting, the motor is indexed 90 ° to the vertlcat position so that the blades are between the table tap and the motor and the yoke is indexed 90 o clockwise and locked° The sow is moved back on the radio1 arm and locked to the arm when the amount of the blade extending forward of the fence is equal to the depth of the rabbet desired, tf the depth of the rabbet is large, do not attempt to cut it in one operation. Lower the radial arm until the blades are in a position to cut the desired width of rabbet in the edge of the board, The bottom of the saw guard should be parallel to the fence and the discharge elbow directed to the rear of the sown

MOLDING OR SHAPING

Th_swork is done using the Craftsman Molding Cutter Head and a set of cutters depending on the type of molding cut desired. This work is done with the saw in the some position as that described for rabbetlng_ See Figure 32. Since the position of the cutters with respect to the fence and the

table top can be adjusted any or all of the cutter shapes can be used.

ROUTING AND DOVETAILING

Routing and dovetailing are done with the motor indexed and locked 90 ° from the horizanta! except that this time the externally threaded stub end opposite the normal blade end is between the "motor and the table top. The foffow- ing chucks will mate with this external ½-20thread: (See

Routing may be done by either moving the work wffh a stationary router or by clamping the work to the table and

moving the router. Always approach the router bit from the left hand side af the saw.
