and please allow me to introduce myself first.
I am Jörg Sprave, 45, a German. My main interest is designing, making and presenting slingshots. I run the (non profit) "Slingshot Channel" on youtube, which has been growing quite a bit these last two years.http://www.youtube.com/user/JoergSprave
My work does not only cover the conventional Y-shaped fork, but I also made complex pulley equipped frames, slingshot crossbows (firing balls and arrows), flechette shooters - and slingbows.
My slingbows are very basic, homemade arrow shooters that are powered by rubber. Other than that, a slingbow is very comparable to a recurve bow, with no reduced let off like a compound. The energy levels are also quite comparable. But I think it is much easier to make a slingbow than a recurve bow...
Here are a few videos about slingbows.

None of my "products" are for sale, and I have zero commercial interest. This is just a great hobby for me.
I have no idea if my little slingbow presentations are welcome here, but I thought I just give it a try.
