CRAFTSMAN MOUNTING AND SHARPENING

1 Remove saw blade from power table and replace with grinding wheel furnished with the CRAFTSMAN unit. Top of bevel should be at left.
2 Drill holes in block () (figure 2) to correspond with those in miter gaug If the miter gaug does not have holes, they may be drilled through the gauge and block () and fastened with flat headedbolts and nuts or clamped. Position the holes so that the CRAFTSMAN unit may be moved
either to the right or left. 3 After block ① is firmly affixed to the miter gauge, place the CRAFTSMAN unit on the block ① as shown in Figure 2. Bolt and wing nut ③ may be inserted in any of the 3 holes depending on distance
Remove index plate which is on the CRAFTSMAN unit for shipment by removing wing nut Q, lock washer C and washer C. 5 - Take blade to be sharpened and if it is a blade with evenly spaced teeth
such as the standard combination, rip or cross cut variety, mount the blade on index dial (1) (the dial with 8 rows of holes) by putting the blade on the index dials threaded spindle. The direction of the points of the teeth on the blade may be determined by placing the blade on the After the blade is correctly placed on the index dial spindle, secure it in place with nut O . If the blade to be sharpened has an arbor hole , insert correct bushing provided prior to securing the blade on the spindle. Nut D should be tight enough so that blade will
- If the blade to be sharpened has a diamond or square arbor hole that correspond to the ½", %" or ¾" round arbor holes, the bushings provided may still be used since they will touch on four points of the arbor hole and keep the blade in proper position.
- For blades of the master combination variety, i.e. those with grou small teeth with a large raker tooth in each group, use index plate 🕲 . (The dial with 5 rows of holes.) Refer to charts (1) or (2) to determine which row of holes to use in sharp-mine the ROM NUMBER IS DETERMINED BY COUNTING FOOM THE

4 Remove index plate which is on the CRAFTSMAN unit for shipment by removing wing nut () , lock washer () and washer ()
5 Take blade to be sharpened and if it is a blade with evenly spaced teeth such as the standard combination, rip or cross cut variety, mount the blade on index dial (1) (the dial with 8 rows of holes) by putting the blade on the index dials threaded spindle. The direction of the points of the teeth on the blade may be determined by placing the blade on the dial and holding it over the grinding wheel prior to securing it in place. After the blade is correctly placed on the index dial spindle, secure it
- in place with nut D . If the blade to be sharpened has an arbor hole other than 1/2", insert correct bushing provided prior to securing the blade on the spindle. Nut D should be tight enough so that blade will not rotate on the index dial.
  - If the blade to be sharpened has a diamond or square arbor hole that correspond to the 1/2", 5%" or 3/4" round arbor holes, the bushings provided may still be used since they will touch on four points of the arbor hole and keep the blade in proper position.
  - For blades of the master combination variety, i.e. those with groups of small teeth with a large raker tooth in each group, use index plate 🕑 .
(The dial with 5 rows of holes.) 6 Refer to charts (1) or (2) to determine which row of holes to use in sharpening. THE ROW NUMBER IS DETERMINED BY COUNTING FROM THE ARBOR HOLE TO THE OUTSIDE CIRCUMFERENCE. The letter S is engraved on each dial and this should be the starting

row when sharpening.

It is suggested that the number of teeth be marked on the blade for future sharpenings.

7 After the blade is securely affixed to proper index plate, place on post and secure this unit with washer (), lock washer () and wing nut (). Wing nut () should be tightened enough so that the blade and index dial may be rotated but not so loose that it will rotate without effort. and may be rotated but not so loose that it will rotate without enorm. 8 — Loosen wing nut ① and insert index arm ① into predetermined row of
osen wing nut U and insert index arm U into predetermined row of holes for the blade to be sharpened. The index arm may be inserted in starting hole either to right or left of wing nut U , whichever is easier after adjustments are made and which leaves the greatest distance between wing nut and starting hole. 9 — Safety guide rest () is provided to make the unit steady on the saw table,
if any adjustment on this item is needed it may be done at this time, but ordinarily if the CRAFTSMAN unit is affixed to block f and tightened, the safety rest should adjust itself to the table and all that is needed is to tighten the bolt which holds the rest to the CRAFTSMAN unit.
0 Adjust the first tooth to be ground to the grinding wheel by loosening wing alust the first footh to be ground to the grinding whee by loosting whey nut () and wing nut (), and turning index plate with blade affixed so that the tooth to be sharpened will contact the grinding wheel in the desired position, normally as near the original sharpening as possible. The grinding wheel may be raised or lowered so that proper contact is made. If the saw has a tilting arbor, this feature may also be used to gain adjustments.
gain adjustments. 11 After the desired adjustments of the tooth to grinding wheel is obtained, tighten wing nut ① and wing nut ③ . Since the index arm has been in the pre-determined starting hole on the index dial, tighten wing nut so that arm is securely held.

Make certain that index arm is at right angles to the index plate and not slanting either up or down.

12 Prior to the start of the actual sharpening, adjust the height of the grinding wheel so that it barely touches the first tooth. REMEMBER THERE IS A POSSIBILITY THAT THE TIP OF THE TEETH WILL BURN IF TOO MUCH IS GROUND AT ONE TIME. IT IS BEST TO GO OVER A BLADE TWICE THAN TO GRIND TOO MUCH AT ONE TIME.
13 With the CRAFTSMAN unit attached, the proper adjustment of the first tooth to be ground to the grinding wheel made, the index arm inserted in the to be ground to the grinning wheel made, the index arm inserted in the starting hole and firmly secured by wing nut () , the blade is ready to be sharpened. Prior to turning on the power, push entire unit over the arinding wheel to make certain adjustments are correct and that the first tooth contacts the grinding wheel properly.
14 Since all set-up adjustments are done with unit in front of grinding wheel, turn power on and push entire unit over the grinding wheel and the first tooth will be sharpened. Pull the unit back to starting point, raise the index arm from the first hole and rotate index plate and blade to the right until the arm drops into the next hole in the same row. Push entire unit over grinding wheel and return to starting point and second tooth will have been sharpened. Repeat this operation until starting point is reached.

Since most blades have more teeth than there are holes in the index dial, it will sharpen every second, third or possibly fourth tooth. After you have rotated and around the teeth once around the index dial. you have rotated and ground the teem once around the maex ald, loosen wing nut leaving the index arm inserted in the starting point hole and slowly rotate the index dial and blade until the next unaround tooth is adjusted to the grinding wheel. Tighten wing nut () and proceed with grinding operation. If necessary, the same adjustment and procedure is used on the other unground teeth. At the time of this operation and adjustment, no other adjustment should be required other than loosening wing nut

ADAPTING THE CRAFTSMAN SAW SHARPENER TO RADIAL SAWS

Construct a jig from wood using I" stock and making two pieces approxi First: mately 3" x 8". Screw these two pieces together at right angles the long matery 3" x 8". Screw these two pieces together at right angles the long way. The purpose of this jig is to take the place of the miter gauge on a table saw and to have the upright piece of the wooden jig accommodate the aluminum casting which holds the index plate, blade, etc., when a table saw and to have the upright piece of the wooden lig accommodate the aluminum casting which holds the index plate, blade, etc., when sharpening. The wood jig also replaces the masonite block furnished with the device. Holes are drilled in the upright piece of the wooden jig to compare with the ones drilled in the masonite block furnished.
Second After the jig is constructed and the aluminum casting affixed in the some manner as it is on the miter gauge of a table saw, the assembly is then either clamped or screwed on the radial saw table in line with the motor either clamped or screwed on the radial saw table in line with the motor arbor. The grinding wheel is installed on the motor arbor instead of the saw blade. It is suggested that a blade be put in the CRAFTSMAN Sharp-ener during this operation so that the sharpener may be aligned with the arinding wheel which should pass over the blade at a 90 degree angle. If there is not enough clearance with the unit directly in front of the motor it there is not enough clearance with the unit directly in front of the motor arbor, place it to the right of the arbor and tilt arbor to obtain proper adjust ment of the grinding wheel to the blade. (see illustration).
After the CRAFTSMAN Saw Assembly is lined up with the grinding wheel, the wooden jig is then clamped or securely screwed to the radial saw table. Grinding the saw is accomplished by drawing the grinding wheel over the blade and using the same directions as on a table saw. The only over the blace and using the same directions as on a table saw, the c difference is that the grinding is done from above rather than below.

NOTE: There have been instances where there is not enough clearance NOTE: There have been instances where there is not enough clearance between the grinding wheel furnished with the CRAFTSMAN unit and the assembly when affixed to the radial saw table. To overcome this, it is suggested that a smaller diameter grinding wheel be obtained and dressed to a bevel similar to the wheel furnished with the CRAFTSMAN
