Welcome to the forum MFIW. If you think you need the box in order to get good dust collection that isn't true. You can get excellent results with a pickup on the fence. Then you don't need to worry about attaching it, or how to get power to the router, or turning it on and off if you don't have a remote switch, etc.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
