Hope we didn't sound like we were raining on your parade. My hat is off to anyone who can succeed at building a rod with a minimum of money and a maximum of ingenuity. Clearly it CAN be done.
But a lot of us on this forum must sadly admit that at one time or another we started a new project only to realize half way into it that we had drastically underestimated the total cost of all the parts and pieces we would need. Our notes of caution are not intended to diminish your enthusiasm or to try to tell you how you ought to build your project. We're just trying to pass along bits and pieces of what we have learned from our own mistakes.
Keep us posted on your progress...or better yet, start a project journal right from the git-go with lots of pics.
