Sometimes you can remove inserts by screwing a field tip in and carefully heating up the tip only. The heat will transfer to the insert then to the glue and you should be able to pull the insert out. Be very careful not to heat the carbon just the field tip and don't use too much heat. Then use a 24 hour epoxy to reinstall the inserts and orient your blades the way you want. Just curious as to why you feel the need to align your blades? I have seen no real advantage or disadvantage to doing so. Unless it is to clear an arrow holder or something of that nature.
