how do I make pontoon tubes for a scale model pontoon boat?
i’m really into r/c boats, cars, planes, etc.
and i like to make scale models of stuff like that, and i want to build an r/c pontoon boat; to do that i have to make it float, and i don’t know how, to make my own pontoon tubes, or where I can buy any, so i’m wondering how to make my own. if you can tell me how to make the tubes the boat floats on, or give me a link to a website that sells them, or any ideas you might have, please let me know. ur help would be very much appreciated. thanks for your help.
Use wooden dowels, shaped accordingly. A soft light wood like pine or cedar would be ideal. Balsa wood or foam would also work.
