Rob, Fantastic! I sure wish we would have put our requirements into our last P.O. The G.M of the manufacturer of this machine flat out promised and guranteed a certain CPH after reviewing the products that we would be producing. When the machine w

Bob, I don't have 300 stencils only about 83 so my way might not be practical for you. This is what I have done. 1. I have racks that hold 20 stencils, 10 top 10 bottom. 2. Number the racks and have them in order. 3. Made a number system for locati
