Hmmm ... you're measuring at the widest point and then shifting it up .007". Do you really think the number will be "a few thou" different? I'll bet you the change doesn't show up on the dial indicator!
As for John having it surfaced ... another instance of him needlessly spending someone else's money. Yes, by all means check the runout, but if it is out of whack its easily resolved with shims cut from feeler gauges or pop cans instead of dishing out $100 to have it surfaced.
