A good repair technician should be able to repair 90 percent of the breaks he encounters successfully. What about the other ten percent? These are repairs that cannot or should not be attempted. Recognizing these before hand saves a lot of time and aggravation. Examples of these breaks fall into the following categories:

Size Stars, bullseyes and combinations larger than a half dollar. Some technicians limit them to the size of a quarter.

When you run into one of these unsolvable problems, don't waste your time or lose confidence in your ability, just move on to the next job.
