Today, I received my Matrix 380 Blackout with 10 Diablo carbon arrows already assembled and I removed 3 nocks in order to replace them with Lumenoks. I know a lot of you already know this but I just wanted to share a super simple way of removing a glued nock from a carbon bolt without ruining the bolt.
I took an 8-32 x 1" machine screw with a nut for a lock stop and threaded it 4 full turns into the nock then proceeded to lock it down with the nut. I then put the head of the screw into a vise and locked it down tight on the vise so that the bolt (arrow) was horizontal (3 or 9 o'clock position.) After that I began to heat the screw and simultaneously applied twisting pressure to the bolt and as soon as the glue reached its melting point, it slipped right off. The carbon bolt was warm to the touch but it never got hot.
There's an easier way. I just shot one of mine into a rhino Block. When I tried to remove it using my Excal arrow puller, the nock came right out! The rest of the arrow took a little more work.
Newbie question: what should I use to re-bond the nock into the shaft?
You don't glue the lighted nocks since you have to pull them out in order to service them. The Lumenoks are actually activated by making contact with the end of the bolt. When the bolt is launched it pushes the nock against the end of the bolt therefore closing the circuit; so to turn it off you have to actually back the nock off a hair in order to break the circuit.
