Project Information
I got the idea to make these off of a YouTube video (http://www.youtube.com/watch?v=zJu13EpiEAA). I have about $14 in hardware to make two clamps. As he states, the bonus to making them this way - as opposed to other videos - is that you can take the screw mechanism and attach it to other lengths of wood of whatever length you need. It is absolutely remarkable how much torque these rascals will generate.
