How can I use position tolerance for the 4.76 hole in the attached drawing? I do not know where to place the datums. I want the 4.76 hole to be on the center using the given tolerance. Thank you.
I would like to as if it is possible to passivate grade 202 of stainless steel without affecting its surface (corrosion to nitric acid) or affecting its dimension.
Thank you.
