An even better way is to use an EMT conduit hanger from the electrical supply section of any hardware or building supply store. You will also need an old mouse pad. Purchase your conduit hanger or clamp selecting a size about 1/4" larger than your handlebar. Cut a strip of the mouse pad to fit the inside surface of the hanger and glue in place. Put a 1/4 X 20 screw and nut on the hangers mounting hole. Screw the camera on the 1/4" screw and put the hanger on your handlebar and tighten the hangers clamp screw. The mouse pad will provide vibration isolation and a nice gripping action on the handlebar. Below is a photo of two hangers bolted back to back for mounting a Mag-Lite Mini-Mag AA 3-watt LED flashlight to a handlebar so you can see how easy it would be to use one for clamping your camera to your handlebar.
