Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Robynsaddiction-at-aol-dot-com> Patrick, Usually, if I look on the top shelves at Home Depot here in Kansas I will find a 50 ft roll of . 25" copper tube. However, you can just use a bolt with it's head cut off to thread into the ends of the tubes that you will be splicing. Hope this helped:^) Rick
