if u have pics of ur shot pinged rods please post....

 

shot peened not pinged. the changes that are present are more on the tensile strength , almost molecular level, and is not really apparent to the eye. if you doubt your machinist did the work, just ask him, or go to another machine shop with the part and have them analyze it. they can tell

a quick set of examples

another example, but utilizes a laser instead of media shot. (most used in automotive chassis design and transmission parts.. much more expensive than media)
