I work at the Home Depot, and when I went to the COPK and saw the long metal bars people were using for precisions and bar practice, I knew immediantly I needed some to train.
So, as soon as I got back, I bought the materials I needed without doing much research, and it came to $40 for just one practice rail

Other forum friends gave me the idea of picking up the metal piping from old junkyards and such, but I just wanted to know what others thought, and if anyone had any ideas/past experience.
