Get uni bushings! You will love them. Much nicer to index your nocks and fletchings.

I just got some new arrows and they came that way, my dealer said they are pretty much going to make all of them that way now since everyone uses them anyway. Certain brands and sizes will still use glue ons though I think.

However super glue gel should work, but epoxy would work better. I'm not sure if hot melt glue like you use on insert would work well or not. I've never built arrows with glue on nocks.

Are you trying to re-use the arrows you robin hooded? Don't do that, either put them on display or pitch them. Chances are neither one is any good anymore. The one you stuck the arrow in is junk for sure, the one that stuck in it may possibly be bent now, I would check it before using it again.
