Abstract
A lathe center can include a boss formed in a cavity of a work end of a work piece, such as a shaft. The boss has a height as measured from an end wall of the cavity. A support recess can be formed in the boss, and by limiting a depth of the support recess to no more than the height of the boss, stress and strain around the cavity during startup and/or operation of the work piece and/or an assembly including the work piece can be reduced.
