Hello, I have acquired a Tenryu Yellowtail SK732-50YT that is/was a 2 piece popping rod. I could not remove the 2 halves no matter what I have tried. I have tried to iced at the joint and it did not help. I tried to have another person holding onto the butt section while I try to twist and pull and it did not help. Is there another technique to remove/disconnect stubborn rod pieces without damaging them?
