Heat is the big danger with carbon arrows, they can be removed by screwing in a field pt and applying only enough heat to the field pt, never the shaft, until the bond loosens, but an easier method is to use a long drill bit just big enough to slip inside the shaft by removing the nock and hold the nock end of the shaft and sling by sharply snapping the arrow down so the bit slides down and hits the back of the insert. Normally a few tries and it will pop the insert out! Good luck! Mark
