Sherline 4-Jaw Independent Chuck Model #1073

    For Use with Older Sears 6" Lathe,
    1/2"-20 Spindle Thread

    4-Jaw chucks have four advantages over 3-jaw chucks.
    (1) They can be used to hold irregularly shaped parts.
    (2) With the use of a dial indicator, they can be used to center parts with a great deal of accuracy.
    (3) Four-jaw chucks can be used to deliberately hold a part off-center.
    (4) They can clamp stock tighter.
    This is a valuable asset when machining cams, crankshafts, and similar parts.

    The main disadvantage of the 4-jaw independent chuck is that the jaws must be individually set, adding considerable time to setups.

    Like the Sherline 3-jaw chucks, the 4-jaw chucks can be used to clamp either externally or internally. This 2.5" (63mm) 4-jaw chuck is designed to grip from 3/32" (2mm) up to 1-3/16" (30mm) diameter stock with the jaws in the normal position. For larger diameters, the jaws must be reversed, and can grip up to 2-1/4" (56mm).
    The chuck has a .687" (17mm) through hole.
