Bryant Racing began manufacturing crankshafts in 1982. Initially, Bryant used the norm at that time…gas deep case nitriding…performed "by others", and so had encountered the many problems associated with post grinding. It was also thought the steel used at that time needed the compressive strength that deep case provided.
Crank grinding is the worst money maker in my shop. I charge $150 for a typical V8 and it takes a minimum of 1.5 hrs per. But I take the time to match radiuses, equalize the strokes, correct the index as much as I can, and I always sweep every journal. And like a previous poster mentioned, I set up on the snout and the rear seal surface.

Grinding Norton Commando crankshaft. Many motor cycle components, especially those from the engine, need to have a superior finish or tighter tolerance to that which can be achieved by turning or milling. For this reason, grinding is an important process, without which interchangeable parts and low friction movement would not be possible to ...
It is recommended that crankshafts be finish ground. Wet grinding using a soluble cutting fluid and wheels of medium hardness with vitrified bond are normally recommended. Silicon carbide or bauxite grit with a grit size of 30-50 are also acceptable. a) A suggested grinding wheel would be A60-301J7-Vi5 or its nearest equivalent. ...
