I have provided images depicting making bolt stop ejector springs. You will notice a wire forming block with 2 pins that are .100 ths. Space between pins is .050 ths. One pin is shorter than the other to allow the circular forming of the spring eye. Bend 35 degree angle first and then form the eye. Then, straighten the wire legs until they are parallel, place it over the long pin, and complete the other angle. (Note This is the basic form where magazine lock springs can be made for the P72 and M78 rifles. (May fit other P-Series rifles) Continuing with the bolt stop spring: Place the open ends of the legs in the extractor groove of a 30.06 case and form the contact leg for the spring tensioning. Next, use needle nose pliers and bend the contact arm slightly down to give clearance for the ejector. Next is: place the form over the 90 degree bending tool and bend the 90 degree angle. (Note The 90 degree bend that protrudes into the ejector should be approx. .150 ths. Cut the other leg as required for the bolt stop assembly. See image examples to see what the form should look like. Once all adjustments to spring are complete, follow the stress relieving instructions on the wire pack. Jim
