>>>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
