>>>Carsten, You mentioned that I should not bother with stainless steel for my small output shaft.  What would you suggest for that instead? 

I found this info:

Is a 4340 a similar alloy? I can get that from McMaster.  Cost is the about the same as SS.  How hard will it machine in my lathe?   I was prepared to machine the SS.  Will this be tougher? 

Also, I am figuring you have some background in all this? 

Thanks, Dan Pfeiffer
