Shops mark things that are supposed to go in a particular place,order, or match up with machined surfaces.The rods had markings from other shops on them (in this case stamped letters/numbers and indentation dots) so I lined them up in order and did them the way we do them in this shop because I may loose some of the other markings as I work on them. I zipped the lock side of each rod with a disc and etched a number in each with a dremel. You may be able to see the 7 etched in the rod on its side and dots on the bottom of some of them. After that I removed the caps and bolts so I can start grinding them.
