Andre; My remarks about knobilling pins, wave envelopes and framuses, were my frail and feeble attempts at humor. This in face of a rather inexplicable phenomenon. The question at the end was serious though. Let me ask it another way. Is the change in tone as evident on a single strike of the hammer (from the rest position) as well as on swiftly repeated strikes (hammer in check position rather than at rest) ? Jim Bryant (FL)
