Glue in nocks help

[Big Bear 44]

I shoot xx75's 2315, with old fashioned glue in knocks. My question is I want to change fletchings but I would rather not have to change all the nocks, so
a: can you change the orientaion on a bitz jig to line up the cock vein for a prong type rest or
b:how do you easily loosen the knocks to turn to the correct orientation with out totally detroying them and taking them off. Any help would be appreciated.

you just figure out how you want your nock on the string, and if you want cock feather down, picture where it would have to go. then glue on.

or go to your local pro shop and have them cut the back end off and install unibushings so you dont have to worry about it.

How were they glued in? Hot melt? Hot water will get em out if so!!;)

fletch tite glue. Ever heard of heating the shaft slightly and just turning them?
