I am not mistaken about the conversation, I was specific and so was he.
If any issues, call Crankshaft Specialist.

BS! First, you can't grind hard chrome with any crank grinding wheel I've ever used. Do you have any idea how hard the hard chroming process actually leaves the journal? We used to occasionally get diesel cranks (marine applications) that had been hard chromed. You had to physically remove the chrome before attempting to regrind the journal. If hard chroming deteriorates, you're looking at a new crank because it can NOT be repeated(unlike nitriding). Tell me: exactly HOW do they propose to have chrome on only ONE side of the journal?When you offset grind a crank, you add material to the bottom side of the stroke to lengthen the stroke. You add material to the top of the stroke to shorten the stroke. The plating process leaves an even thickness of material over the entire surface...
