That's one reason I wouldn't recommend using superglue to install inserts. You don't have time to work with them to get them aligned right. Use 24 hour epoxy instead.

To get that one out, carefully heat the insert, just enough to get it out. Heat a little, latch onto it with pliers and pull. Heat a little and pull. Just be patient and it'll eventually heat up enough to come out. The trick is to heat the insert up enough to weaken the glue around the insert without melting the shaft. Otherwise you'll wind up with a brand new, ruined arrow.
