My luck usually is. It mic's .001" over, put some emery to the surface, get it looking pretty. Measure again and it's .0005" under! Hello Loctite. And I keep three different flavors of it, too!
I make inboard boat shafts from marine grade SS. straight motor coupling need to fit so you can drive them on with a block of wood and a hammer. the shafts can be on size to .001 over. the couplings are 1.5 to 2 thou under. We have to polish it with 80 grit emery to size. I have to ice it down before micing. after till it gets there. need about .0005 for a good fit. I have miced a shaft when hot and it was .0005 bigger than when I started then ice it and it is .0005 under.
