Shawn, you should be able to change bits by changing the height adjustment on your router to all the way up.(This means dropping it as far as it will go in the table) You can get replacement screws at the hardware store, just take an old one with you for sizing. You should have no problem building the Router Workshop table. You have the skills to do this, just take your time.
