It really isn’t hard to do, especially if you are only replacing one. When making a rod from a bare blank care must be taken to keep the guides straight and on the correct side of the blank.
Is adhesive necessary? I'm guessing it's gonna be a very snug fit. The guide is fine, it's the insert alone that's broken. I've been reading and some claim they're ceramic, and others claim to be some type of alloy. I really don't care if it "matches" the rest, just need to replace the insert.
