I guess I'm just not familiar with the carburized process to really understand. I have some experience with destructive testing and despite the fact that it is expensive it does prove which alloy/process is better. Anyhow, I'll take a better look at the NBT shaft; I just want to make sure I get the better piece is all. Out of curiousity, where does one buy a NBT output shaft? I'm pretty sure the
25 spline group buy is probably closed by now.
