    If I can find that discussion I will post the link. At first I thought it was just cheap parallels. This can open up a whole can of worms on GDT & parallelism and flatness. Even though I laid them flat on a surface, would there be a situation where you may put a part between two parallels? If you do, then you are off by whatever the flatness of the parallel was which in my case could have been .05.

    I guess if you want to check your parallels you should lay them on a granite surface and slide them under a DTI. I will do this later just for the curiosity factor and knowing they are in tolerance (not a cheap set). Also, will let me know what the flatness tolerance is. As a reminder I may mark the sides with a note "DO NOT LAY PART ON THIS SURFACE"

    And as Don said, normally used in pairs.
