If the inserts are already glued in, can't do it. They are glued in w/ epoxy, and when it sets........It's done.

If you start from scratch, screw your broadheads onto your inserts, mix up the epoxy, then install the inserts, you can spin them to align the blades w/ the fletching. Lay them flat for 24 hours to let the glue set, and you're done.

Is that the info you needed?
