I got the Ridgid router combo for Christmas. So far it is a great router, but I have a question about the plunge base. I have never used a plunge base before, so I don't know if this is normal or not. The plunge base plunges smooth when you use both hands and the bottom of the base is completely supported by a work piece. But if I have a bit with a bearing on it and want to set the plunge for a certain depth of cut and try to plunge on the edge of a workpiece, it is very hard to plunge. It seems like any slight pressure that is not totally downward causes it to stick. Is the just the way plunge bases are? Should the plunge only be smooth if the base is completely supported by a work piece? If I have slightly less pressure on one hand on a bit more on the other it sticks too. I have lubed everything that can be lubed. Any ideas? I don't want to return the router if I just don't know what I am doing.
