You guys should try make one. There pretty easy compared to a bow. To me trickiest part is nipple. Gotta be just right length and depth that they say ingaged long enough, but disengage when they need to. I'm sure there's lots of little secrets to make em better than mine, but it's fun to toss around. I'm thinking Atlatl golf would be cool.
