With the rods marked and disassembled it's time to start working on them. In this first step I'm using a carbide bit to grind away the ridge in the center of the side and blending into both ends. Care needs to be taken to keep rods even when viewing the sides not being ground and also not to remove too much material. The square "chunk" of metal at the top of the rod is left alone and will be ground a couple steps from now when I "balance" the rods. The bit in the tool is used for steel, the one on the bench for aluminum. The last person who used the air tool before me had been doing some welding repair work on aluminum heads.
