Shoulder key knobs:
Preping key tabs for the shoulder connection. I had to figure a way to make them adaptable for screws. At my job, we use these screw revets on a air tool. I pocketed four to test out and they work great so far.
I photographed the process of moddind them (I order in the pics below). You have to first get some clippers and cut the end with the groved band off, pry it off with your thumb and twist then screw in to be sure no burrs were created. Then, carefully hallowed one if my keys and inserted. I will need to use an adhesive to permanently bond it in.
