Weird, I was just outside having a smoke and racking my brain on this issue. I don't have a problem with them moving or coming off but I've broken a couple CF rods. But here's my process. And firstly, forget the glue, it doesn/t work. Firstly, dremel a flat spot on both ends of the rod. Secondly, with the rod inserted in the metal part, put a drill bit into the hole where the setscrew goes in and drill into the rod a just a bit. Now with locktite on the setscrew, screw it in. The set screw will set into the recessed hole you drilled and lock the rod into place. Finally, I wrap the connection between the rod and the metal with a few turns of electrical tape for added security. DO NOT stick the GPS module onto the plate until you've done this because it has to be pointing perfectly forward, and because of the flat spots on the rod, there's no way of adjusting it once you're done. Hope this helps.
