The total amount of “in-feed” can be pre-selected from 2 to 35 teeth (0.002 to 0.035 inch), by setting the knock-off arm located directly behind the ratchet wheel. In-feeding stops automatically when the knock-off arm has rotated around and makes contact with the ratchet “pawl.” Figure 3-13

1.Remove the drive coupler form the spin motor.

2.Slide the limit stops to each end of the stop rail so that they do not interfere wit the ratchet mecha- nism. Otherwise, undesired infeeding might occur unnoticed.

3.Disengage the traverse.

4.Adjust the wheel head out away from the reel 1” to 1-1/2”.

5.Move the finger guide into position. Maintain a clearance no greater than 1/8” between the guide plate and grinding stone—the closer the better. Figure 3-14

NOTE

Look down on the reel from immediately above the grinding wheel to be certain that the grinding wheel makes contact with the reel blade on one corner only. The peak of the finger guide must be directly below this point of contact. If you have another reel in which the blades “spiral” in the opposite direction, the grind- ing wheel will only make contact on the opposite cor- ner. For this reason the finger guide plate must be reversed.

The helix, or “spiral” of reel blades differs according to the manufacturer. A close look at the finger guide reveals that the peak is positioned to one side of the grinding wheel. When the leading edge of the reel blade contacts the “right” side of the grinding wheel for relief grinding. If the leaking edge of the reel blade contacts the “left” side of the grinding wheel for relief grinding. The finger guide plate is reversible to allow for his adjustment. Also, the hole in the finger guide plate is elongated to allow for readjustment as the stone wears.
