The eccentrics are chucked by tighteningtwo nuts which clamp them sufficiently to take heavy cuts. Thechuck is so designed that it will take as many different sizes ofeccentrics as may be desired by simply changing four grip CHUCK FOR ECCENTRICS. BY C. L. DICKERTAssistant Master Mechanic, Central of Georgia. Macon, Ga. A chuck for boring and turning eccentrics on a boring millwith one chucking is shown in the accompanying photographand drawing. The chuck is simple in design, and is easily ap- Eccentric Chuck Attached to a Boring Mill blocks and two studs from one hole to another; it is also madeadjustable for any throw of eccentric. Either the boring or the turning operation can be performed ;t I o o V-Iji-A <-§-= ^iJiM
