It is fairly simple to increase the depth of your EMA prep in the field. Here are the tools you will need:
- Ball Pin Hammer
- A 2nd Hammer of almost any design
- Ear Plugs or other Hearing Protection
- Place the rounded end of your ball pin hammer in the punch and dimpled prep.
- 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.
Note: Do not attempt this in the field if your frame does not have a pipe sleeve type support.
