If your looking for a quick easy fix and not as concerned with looks, here is a method I have used for rod tips and eyelets many times without fail. Use J-B weld, the quick set version (I think it's called J-B Kwik). You can buy the stuff at any hardware store, autoparts store, probably Wal-Mart. It's an epoxy, but sets in 5 minutes and is super strong and dark grey in color when mixed, so it matches graphite rods well. When replacing eyes in the middle of the rod, I just mix it, put some on the rod all the way around and stick the eye to it, put some more on to cover the whole deal. Then wrap some thread around it before it sets, trim the thread ends and smooth it out a bit with your finger tand your there (remember sets in 5 minutes). Easier than all the rotating with the longer set epoxy.
