What grade of 4140 will you be using out of curiosity. Pre-Hard, Annealed etc. Just curious as thats the kind of stuff I do and I'm always interested in seeing that kind of info. Just like the Control arms I think I spent way more time thinking out tool paths and looking at the milling surface finishes than most people would.
I do love 4140 though. Beautiful to work with. After working with 1045 and 4140 for almost every job I do, any time I go back to a 1018 mild steel its rather depressing. Love the surface finishes you can get so easily.
