3 Jaw Self Centering Chuck


3 Jaw 3¼" diameter self-centering Scroll Chuck (steel body) with reversible aluminum soft jaws ¾ inch -16 tpi thread. This is a simple three jaw chuck a lever inserted in the chuck body moves the jaws open and closed guided by an internal scroll. Unlike most small lathe chucks it has aluminum soft chuck jaws. For general use a small washer (supplied) is held in the back of the chuck jaws to take up scroll backlash and the jaws are bored to run true. Any three jaw chuck will never be without runout at all possible diameters due to variabilities in wear on the scroll mechanism. It will run exactly true at the diameter that the jaws are bored out to. Thus for repetitive chucking work the chuck can be bored for that size and be just as accurate as a collet chuck. Also steps can be machined for larger work discs and the like. They can even be drilled and tapped for stops or hold downs for odd shaped work. Extra Jaws are available as are "full circle" or "pie" jaws which can be used for holding thin delicate disc shapes with minimal distortion from clamping pressure.
