A bit late on the GoPro craze, but I've decided to try to assemble a Jaw Clamp mount. found simple tutorials so I just followed along to see how easy it would be(tremendously). For around $4, you can have a clamp mount a fraction of the official accessory cost.
Step 1: Tools and Materials
Bolt that fits GoPro tripod mount*($.20)
2 Nuts that fit bolt*($.09 ea.)
Jaw Clamp(around $3)
*Completely forgot measurements for nuts and bolts, but just take the mount with you(not a big piece)
Step 2: Assembly
Drill a hole approximately the size of the bolt into the clamp(I chose the curved area and off to the side to avoid the reinforcement). After that, fit the bolt into the inside of the clamp and secure the nuts. After you should be able to secure Your camera onto whatever you need, I did this project for music purposes but the possibilities are endless!
