Sherline Self-centering 3-Jaw Chuck Model #1070 (2.5" O.D.) For use on old Sears 6" Lathes
1/2-20 Spindle Thread
Three-jaw chucks are designed so that all three jaws move together and automatically center round or hexagonal parts stock to within a few thousandths of an inch. 3-jaw chucks provide the quickest and easiest way of holding work in the lathe. For this reason, they are the most popular of the Sherline accessories. The Sherline 3-jaw chucks are designed so that they can be used to clamp externally on bar stock or internally on tube stock. This compact chuck is a good all-around workhorse for most lathe work. It has a clamping range of from 3/32" (2 mm) up to 1-3/16" (30 mm) diameter with the jaws in the normal position. With the jaws in the reversed position, work up to 2-1/4" (56 mm) can be gripped. The hole through the chuck is .687" (17 mm). Rotating the knurled ring closes all three jaws simultaneously to quickly grip round or hexagonal stock. Tommy bars (provided) are used in the holes in the side to tighten and loosen the chuck for more leverage.
