Back in the dark ages, (late 1940s-early 50s) stroker crankshafts were made using the metal spray process. The radius of the crankshaft was changed by offset grinding the rod journal, the journal was grooved, and then built back up to standard diameter once the stroke was altered. That probably handles more stress than an axle rehabbed with hard facing spray welding.
