I'm by no means an expert on forging but I thought the major advantage of forging was the grain alignment? That wouldn't get disturbed when you finish machine a crank or rod as you're not changing the shape, just the dimension. Forging a disk and then hacking it up seems like craziness... especially since all that machining is causing stress risers which are notorious bad in aluminum. Am i wrong? It wouldnt be the first time.
