Let me say first that I'm new to routing...........totally new! After that opening, here's my question. Does a bit always go past the plastic sub base? I want to take a shot at using a rabbet bit, but the diameter won't fit through the base. I thought that the bit was supposed to be even with the plate, then you would adjust the depth setting. By the way, can you suggest a good starter book like routing for dummies or something like that?
