That's true, now that I think of it. The grade only signifies tension

Just the other day I had to remind an engineer that heat treating won't make
a shaft stiffer. I think he was a bit suprised having a tool box pusher

4:1 is tail stock territory though there are things like a follow rest. I've
never used one but I could see them being handy.
