There are lots of Glues but I will say. Loc Tite, because that is what myself and many others use.
If you are putting a tip on that is already shaped to the diameter of the shaft.
Use a Sticky Note around the shaft. Leave just enuff paper exposed over the top of the ferrule to hold the tip.
Apply a small amount of glue to the tip and drop it in the top of the Sticky Note.
With your fingers crossed and a bit of luck, the Sticky Note will center the tip as it was before.
There will be a little of the sticky note paper stuck to the ferrule but a little fine grit sand paper can take that off.
Altho, you could just put a new tip on it.
