After re reading your first post I think I understand your problem better. The throat of many routers is not wide enough to lower large bits through. When I was using my Hitachi M12V in my table I had to install the bit above the throat opening which made it to high to rout the proper profile which is what it sounds like you had problems with. My solution, and I believe I remember MT Stringer using it too, was to add a piece of sheet material, like 1/4" masonite e.g., on top of my table to effectively raise the surface in relation to the bit. Depending on how your table is made you may be able to do the same.
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.
