  • A 2nd Hammer of almost any design
  • Ear Plugs or other Hearing Protection

  2.  While holding the ball pin hammer in the punch and dimple prep, strike the other end of the ball pin hammer with your 2nd hammer. A few swings of the 2nd hammer should do the trick.hammer-on-hammer hammer-near-hammer
