I have had a hard time finding good enough rod tubes to rods with sections 83cm or more. So I decided to make my own. That was easier said than done! First, with help from a metal worker we tried to make handmade tubes out of copper. The tubes were absolutely brilliant, but the cost was waaaaay to expensive. Next was aluminum tubes. But the cost was too high, even then. Then I tried a material which is called ABS-plastic (Acrylonitrile butadiene styrene). This material is used in suitcases and skiboxes. But the material was too easy to break... So I asked some fellow rod builders what they use. To my surprise most builders recommend PVC instead of aluminum. Because aluminum tubes have a tendency to break during transport. So then i tried PVC. I have tried a couple of designs. The tubes are really solid. I keep on trying to improve the design, but I think I will offer these on rods with longer sections. Maybe on shorter sections aswell...
