Hi Kasey and welcome. Many small router base plates are made to accept guide bushings, that's why the hole is so small. Anything over 1 1/4" in diameter won't fit through. You can take the black phenolic bottom off and that will do it but it's not as smooth as with it. I did that the other day with one of mine and it went okay. You could order another one and cut the hole out bigger for jobs like that.
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.
