On Alaska Bowhunting website, they have a good tutorial video for using a little hot melt when tuning before final gluing in with JB weld. to remove with hot melt or even JB weld, they show being very careful not to heat actual arrow but like already mention above, heat a field pt in insert to gradually heat just enough to remove without (hopefully) overheating carbon. For tuning I skip the hot melt and use the saran wrap method already mentioned in a previous response, it worked great for me. Good luck.
