YOUR BUMP HAMMER WEIGHT -- YOUR NATURAL SWING:

An important secret to bumping keys is consistency. You want to apply a standard "THUMP" to the key that imparts the correct kinetic energy to raise all the pins at once. On some locks you strike it harder - sometimes softer, but your blows are centralized around some standard swing. Do you need to strike the key more firmly or lightly at times as a normal approach to bumping? Of course! But the comfort of swinging slightly softer or harder than your natural swing can yield great results in bumping. It is pretty simple: Force = Weight x Velocity. So if your natural swing is rarely striking the bump key hard enough, what do you do? Add some weight and let the tool centralize at your "normal" striking speed. In that way you can go slightly greater or softer with your speed, but you start out closer to the normally required "bump". We made our hammers slightly lighter than the other folks by adding two compartments in the hammer heads. These compartments allow you to precisely match your hammer weight with your natural swing. Tests show that lead shot is the best medium to transmit impact. We have supplied lead shot and "corking" material to let you find YOUR natural hammer weight. We supply two corks and a maximum load of bird shot. Experiment and add our lead shot to the hammer compartments to precisely match your hammer weight with your natural swing. When you are satisfied, glue the corks in permanently.
