Nuts and bolts:
4140 6" OD, Wall thickness .2", 2.75" OAL
Issue: after part is taken out of chuck and destresses, parts warps and suffers from small ovality.
4 different od readings give +- .002 part has tolerance of +- .001
OD is critical and be read differently at the moments:
1. When OD is finished and wall thickness is 1" (before ID work)
2. When OD is finished and wall thickness is .2" (after ID work)
3. """" and taken out of chuck.
Which of these measurements do yall think is the one use?
Thank you
