I long ago convinced myself that ringing is of very limited usefulness but just curious not having a perfect one loose. I hunt cracks with a bar magnet and black fluid, starting at the back. The cracks are not visible by eye, except where been built up by welding. From the sheer number of cracked cranks very many engines must have innocently done very many miles flawed. From selected used bits and with patience surprisingly reliable and long lived engines can often be assembled at very low cost; for modest use hard to justify the now huge cost of a Phoenix. Crack free cranks must have 10,000 or 20,000 miles of original type driving in them; more than many cars will ever do.
