bearings will fail sooner or later. Whenever I can, I use a fence as well as a camp. but this particular cut would not allow it. and I'm used to bearings that work maybe five hours. This fell apart after about 20 minutes of use. If I worked on furniture I would be very angry. I did clean the edges of some decking boards though, so I may be the only one who has ever noticed the ruined edge. and I could use a stock from another router to finish the job. However, there are different quality camps and they are not good enough.
