Hello, I have been search all over the internet on guides or tutorial on cutting an aluminum soda can in half lengthwise *Click link for example pic* I have found plenty of how-tos on cutting horizontally and some lengthwise but cutting the top and bottom off. I wanna cut straight down the middle with top and bottom intact. I have a craft project I wanna work on that would use a soda can half. Anyone have suggestions or how-to on getting it cut like this ??
