Welcome to the forum. If you tried to post a link to the manual, it didn't come through. It probably won't until you have 10 posts. There isn't much to Craftsman router tables. What do you want to know about? Some of yourquestions might be answered if you search router tables here on the forum and if you look at sites that sell them like Lee Valley. If you have a specific problem just ask, someone here will answer it.
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.
