Avoid tear-out when routing
All about tearout
Few things frustrate a woodworker like painstakingly shaping a curvy workpiece, only to have a router bit tear out the grain during final machining. Tear-out occurs when the spinning bit encounters grain that isn't strongly supported by its own structure. It often happens in the transition area from end grain to edge grain, where the wood gives way along the grain, as shown, rather than accepting the shape of the bit. Although tear-out can occur during any routing operation, curved pieces are particularly prone.
Complete Guide to Mastering Your Router
Using the router to clean edges full depth, like using a flush router bit with bearing, I found another way: route the safe areas/edges first and then flip the piece of wood including the template over. Now route from the opposite side than before, now using a flush router bit with the bearing in the opposite end of the router bit.
