Thought maybe someone would like to see one of the advantages of a CNC EDM wire cutter. The picture below shows the original Winchester 21 hammer, the redesigned one cut out of aluminum and in the middle a "bunch" of hammers directly out of the EDM wire. Now all that is needed is to "slice" off as many as you like. It was critical to do the aluminum one first to ensure that it cleared all the other parts and would be on face with the backside of the standing breech.-----Bill
