 Patience grasshopper. CNC'ing an entire car from scratch takes time.

Then I'm going out on a limb and say it's bullshit
We use 3 jaw in our CNC-lathe, and all of the other manual lathes. The only reason you want to use an 4jaw, is when to centre something that isn't at centre by it self if you know what I mean. But then we are talking 4jaw invidual. I have worked in workshop for 10years, and have never heard of that you're saying My "mentor" in lathe, have 25 years of experience, and have never done otherwise either. You may have right, but they who learn you that, must have ment something else? For what reason? |

Cause the parts are not round perfectly and the three jaws tighten on a common scroll/worm what happens is it stresses these, its basic theory, this is why on black steel you never use a three jaw chuck. Every workshop I have ever been in has been the same.
I agree with you and your boss though I basically never myself use anything but a 3 jaw  regardless of it being black or bright bar

Thats maybe what you are going to fabricate. When we have low tolerance on the roundness, we turn the chuck with 3-jaw first, then clamp our parts.
Almost any CNC-lathe I've seen have only 3-jaw-chuck. |
