It worked for me. I got this idea and added a few things to it from a pro shop guy. 1. Cut fiber optics at an angle, not squared off. 2. Put the fiber optic back in the pin hole, hold. 3. Use a screwdriver, heat up the end and place on the fiber optic. (Make sure there is no black on the screwdriver at this point so it doesn't transfer to the fiber optics) 4. Place heated screwdriver on the end of the fiber to causing it to mushroom 5. Heat up the screwdriver again to get the bend correct behind the pin. This way you won't blacken the end or cause it to burn and it's more precise than an open flame. Anybody else have any good ideas? If you don't have enough fiber optic line, you can purchase at sporting goods stores. Take care!
