Machining the Dividing Head The dividing head is the element whichholds the part being machined and isattached to the vertical column bymeans of the base last described. One of the castings before machiningis shown in Fig. 4. The fixture used for the first opera-tion is shown in Fig. 5. The casting is located with the bev-elled stop A and bevel at B, the piecebeing forced against these two locationswith the screws C in the swinging cover. This cover is swung back out of theway when inserting the casting in thefixture. The hole D is- then bored out to l.:-S75in., using a plug gauge for testing. The fixture is made with a revolvingsub base E and a pin at the rear (shownin Fig. 6) with two bushings for l
