Sometimes it's tough to get a good fit, especially with Pure lenses for some reason. The best globe bodies to use if you have to go with glass reproductions are the ones that Pergl make. Got this info from Scott along time ago and it holds true. Same theories apply for tightening down outside bezel screws. I've seen a lot of guys crack a crown because they go too far! When the screw stops turning, YOU stop turning.
