If you've ever needed to mount a camera (or anything that uses a 1/4" thread) on a cylinder, then this is the gizmo for you. Partly inspired by the Manfrotto Super Clamp and partly by the C-clamp you used in wood shop, this will hold firm to whatever you screw it onto. What I really like about this build is that the the DJ lighting clamp has a hole in just the right spot to mount other things (like a ball head) to. No drilling, no cutting and the matte paint finish won't mar whatever it's attached to. It's simple, easy and effective. My favorite kind of project.
