Wow. If the head is deflected .1 inches at initial impact, the mallet will have been traveling approximately 1388 feet/second, approximately 1.25 times the speed of sound. If the deflection is .01 inches, the velocity will still be 139 feet/second, or 95 miles/hour. hmmm... Alan Larson sri-unix!larson
