As not unusual, I think I am missing something here. Coil tapping. OK, I give up what is coil tapping? Tapping with what? I know how to "lift" coils, and I know about snugging the becket bend with plyer tips wraped with masking tape, and I have tool I made from a screw driver with the last 3/16" of the tip bent 90° that works better than a coil lifter in tight places. But I don't tap with those, I use a T handle and loosen the tension, then lift.
