Jeez, it isn't some major skill set to get it right with a tapered reamer. You turn it a little and you check it. When you think you're getting close, you make smaller passes with it with less pressure until it just goes on. If you get it a thousandth or two too loose, go ahead and use it anyway. You'll still be within the margin of error that props are built with. Of all the things we do in this hobby, this is one where the learning curve simply isn't hard enough to worry about.
