I am not a physicist, just a business man with a hobby. But I think that maybe rubber looses less energy in friction (= heat) than air rifles or crossbows.
I have some (legal) air guns. They are 7,5 Joules strong (= weak). They require more power to be loaded than my 39 Joule slingshot crossbow.
Excellent!! I just knew you could not resist. In my opinion you're design far exceeds anything I've seen in the way of slingshot rifles. I especially like the cocking mechanism it is both clean and very safe when compared to a winch or ratcheting clamp. I may have to borrow the idea:). Anyway thanks.
i like both the first and last ones. You did a good job on all of them, but i think the fist one looks quite sexy and light. And the last one looks good but it also looks like i fits better in your hand and therefore functions well. and in my mind that is one of the most important things. So i vote the last one.
I missed a bit of the video at the end, hope i didnt miss another slingshot
