Hello there!
I am a high school student, and I am really interested in Physics, esp. electronics and mechanics; I am not an expert or something, so please don't take it hard on me.
Yesterday, I was bored and I messed around and successfully made a catapult (http://www.algodoo.com/algobox/details.php?id=100119). Of course, not IRL, but on my PC.
I am not advertising or something, but I am just saying, you should check the free software named "Algodoo"; it is a 2D physics sim, worth a shot, and totally free. If you can get it, it is easier for you guys to help me because I am using that program.
Anyways, to the point, I am very keen on replicating Mythbusters' "Arrow Machinegun"(), which is a very simple mechanism, basically containing two sprockets, one roll chain, some handles, a slider, bow, string, release mechanism and other miscs.
The problem is, how in the bloody universe, do you have two sprockets and a chain to reciprocate? I heard Jamie saying "the sprocket engaging the slider", but how?
I would really like it if you guys can draw me a model of how I can do it. It'd be even more awesome if you can use Algodoo and draw it for me!
Thanks a lot! :D
