O.K. So I was surfing the web for "Do It Yourself" speed bag platforms. And I went to www.theboxinggear.com to read their DIY page, and found this strange looking critter. The page never addresses this specific platform.

Now I have seen the desktop speed bags that are attached to a spring and sit inverted on your desktop either attached to a suction cup or small clamp. But I have never seen a rig like this before.

Wonder how well it might work. Anyone ever played with something like this?
