OK, in order to get started with the work on a mass production Rambone slingbow model, I first wanted to convert a Rambone so it can take a whisker biscuit. I simply used a piece of multiplex (what else) and cut it so that I could attach it behind the forks, by means of two screws that fit through two holes I drilled through the fork arms. The whisker biscuit was mounted exactly in a position so the arrow is level with the bands. I also added a distance ring so that the string does not follow the arrow through the whisker biscuit, as would normally happen. It works pretty good. But you can see that it DOES make sense to design a dedicated slingbow that is NOT a convertible. Here are my arguments. - A slingbow needs much shorter bands, as the draw length is limited by the arrow length. Even long arrows are just 32". So you'd have to exchange the bands anyway, or live with a ridiculously short draw length when you shoot balls (and use a pouch for arrows, very awkward). - As you can see in the images, the fork COULD be almost a full inch lower and still the whisker biscuit would not touch the hand. This would reduce the wrist strain by a great deal. A normal slingshot with a fork THAT low would be unsaleable as people would be afraid to hit their hand, but with arrows that go through a biscuit, they will be fine. This will allow people to achieve MUCH better accuracy with strong bands. Note that I use paracord as a string, but I also use a bit of Dracon to stabilize it in the middle. That is very helpful as the arrows nock so much better. Just a short piece of Dracon is enough, it makes a huge difference. Next step, a full prototype with a lower fork.
