It will be observed in the cuts that the side of the cutteropposite the one being ground is always closer to the emery wheelhead than the other; that is, the index on the knee will point about5 degrees beyond the 90 degree point. GRINDING. 235 Directions: Set the vertical swivel so as to depress the outerend of the work spindle the number of degrees required for clear-ance. This ranges from 5 degrees to 20 degrees, depending uponthe clearance required. The manner in which shell counterbores may be ground is. shown clearly in Fig. 157, and but little description is grinding such tools, a stud, which fits the taper hole in thework spindle and the hole in the counterbore, is required. 236 HARDENING^ TEMPERING AND ANNEALING.
