Let me start off by saying that I am twelve years old but love slingshots as much as you guys do! Me and my grandpa used to make slingshots (he called it a flip) out of old wooden crates and tree branches. Just a few months ago he lost his fight with leukemia. I would like to build a natural slingshot in honor of him. I have a dogwood tree in my backyard which I hear is good for making slingshots, and I also have some thera-tube rubber left over from another project. Although I have made several slingshots, they were with my grandpa's help so I will need deatailed instructions on how to make the slingshot. Any help would be greatly appreciated!
