I have had my share of lower back problems. 15 years ago I spent two weeks in traction and four months not working. Now, perhaps the most important tool for my back is the ensolite pad I sit on. Sitting on a hard bench all day is hard on the back. Just that pad changes how long I can sit on a bench. My pad is just small enough to fit into my breifcase size tool case. I became ambidextreous (sp?) to help the upper back, arms and wrists. Constant use of the same muscles causes fatigue. By changing the way the muscles are used periodically, they hurt less and stay stronger. My tunings are faster and more stable , also. I also use a hammer that has a ball on the end. Not the Wonder Wond. My hammer is about 10 years old and came from the now defunct Ford Supply. There was a discussion about hammers with balls on the end on Pianotech about a year ago. You might check the archives for that information. Tim Coates University of Bob
