22.24 In the drill jig shown in Figure 22.21, D 1 is the diameter of the part to be drilled and D 2 is the diameter of the setting roll. Dimension L locates the center of the drill bushing from the locating surface. The Vee angle is 90°. Determine M so that the center of the part will be on the center of the jig bushing. D 1 = 3.75 inches, D 2 = 2.00 inch, and L = 4.25 inches.
