Forgive me, but I am sure somebody already explained various reasons for just where on a table saw wing a router should be located. In my case my table saw fence can go end to end to the very edge of the router table wing and well past the saw blade direction. Therefore the 27” X 18” wing does not need to be limited to dead center in that wing. Can somebody point me to a previous discussion or give sound advice. My brain can see several different reasons why somebody might think off center in different directions might have merit.
