Jimvette59, I agree with everything you said about the copper tubing and vibration. Even with the loop, the copper tubing will still work harden from the vibration and become brittle. You can remove the part and anneal it by heating it to a cherry red and quenching it in a bucket of water. Don't hold the part where the water will shoot out the end and hit you, voice of experience talking.
