Grigg, I agree with you completely on your theory. I have debated this subject in the past with other bolters who don't agree with this practice. I believe using a retaining compound to set the bushings in the spindle will not only prevent the spindle from wearing further, but it will eliminate the tiny bit of slop between those surfaces, providing the spindle isn't already worn somewhat, which would create even more unwanted slop. however, I used Loctite 609 retaining compound instead of 660 . 609 is removable and will allow for a more user friendly press removal for future replacement.
