Guy, That just goes to show ya--I though I had come up with something new. What's the old saying...there's nothing new under the sun? I, too, am very concerned that the tuning tip goes all the way down to the coil. Sometimes, this is deceptive though. Even if the tip rests close to the coil, the gripping point is near the end of the pin. I found that I can ascertain this problem by rocking the tip and watching for the center of rotation. If the tip is not gripping at its mouth, I try another one. I carry about six with me. I also use extra short heads with various angles. I feel that they give a more positive transfer of energy from the hammer to the pin. For grands, the 15 degree angle works great. For uprights, it depends on the overhang of the lid. I prefer the 5 degree angle if the lid allows. I choose a tip that fits snugly. To me, it seems to aid the Rebound which I try to use on every piano. With grands, the finger slap doesn't work, so I use the heel of my hand. I can't achieve quite the same instant release of the blow but it still works very well. Of course, as you know, every piano is different. (That's why I titled my book, DIFFERENT STROKES) So, I try to keep a whole vocabulary of techniques fresh and useable. Some pianos demand the use of a Steady Pull. Others with Type C conditions (the pin moves before the string-- Heintzmans, Mason & Risch, etc) require some tricks. Sometimes, Snap It Up works. I pull the pin until it feels that it has turned the correct amount, although because of the excessive friction at the v-bar, the pitch has not come up to exact. So, I flip the handle clockwise to give a jerk to the string. If the pin has been turned to the correct position, the string will come up to proper pitch and will stay. I guess this is one of the challenges of piano tuning--the variety of piano conditions which demands versatility in the approach of the tuner. Thanks for listening. I hope something was worthwhile.
