Step 5: Glue!
Gorilla glue is my favorite and it's something I have so I went with that. First I dripped it down the pipe and coated the insides but I wanted to use a lot so I put some down the length of the rod. I spun the pipe a bunch and made sure that the glue got everywhere in and around there before setting it out to dry.
I left it standing upside down for one night and continued work the next day; even though the glue wasn't dry then.
