"Can you use 2 pair of needle nose on each side and with the help of another person to unscrew?\n \n\n\n\tWhat about screwing an adapter ring onto it to extend it and use permanent Loctite on the threads. Let it harden and maybe you can unscrew it that way from the extension ring.\n \n\n\n\tThey make pliers for expanding chain links for electrical lightning. You may see if you can find one of that style that fits from the inner ring to unscrew. It expands instead of compressing.\n \n\n\n\tGood luck!\n \n"
