This is not going to get rid of all camera shake but can reduce it significantly as the mass of the camera-stabiliser is increased. More force is required to move it and the smaller forces in camera shake are dampened. Also for the same reason this will allow panning motions to appear smoother.
This cost me nothing because I had the bits lying around, but the piece of metal I bent was from a shelf I purchased from Ikea a few years ago. Turns out they still sell it, over here: http://www.ikea.com/gb/en/catalog/products/10011017/ and cost 10 pounds in the UK. I guess 10 pounds is a lot different from free, but comparing that to what a glide camera stabilizers starting at about 60 pounds, this seems to be worth the try. This system doesn't have a gimbal, but never-the-less it does work.
Step 1: Bend the Metal Piece
The top flat bit should be made a level as possible but you can make a few adjustments a bit later if you need.
Step 2: Screw on the Camera
Starting from the bottom, the first two nuts and washers help secure the bolt to the metal bracket. The third/top nut and washer is uses to secure the bolt to the camera. When securing it to the camera, loosen the entire bolt about a cm, line it up with the hole and
screw the entire bolt in as far as it would go into the camera. Tighten the top nut to the camera, and tighten the other two to the bracket.
You should be done; you can adjust the bend to get a better balance but as there is no gimbal at the end of the handle, you can compensate small deviations with a rotation of your wrist.
