<p>A punch retainer can utilize a spring passage to retain a locking ball and a spring. A retaining member can be disposed in the spring passage to hold the spring and ball therein and to impart a desired compressive force on the spring. The retaining member can be axially aligned with the centerline of the spring passage and can axially compress the spring. The retaining member can be adjusted to adjust the compression of the spring. A single dowel passage can be utilized to accurately align the retainer in a desired orientation.</p> |
