Inverting bracket
One of the bad things about the steadycam by itself is that it makes it very difficult to get low angle shots such as those hovering just above the floor or looking up at a person. To fix this, you can build a U-shaped inverting bracket that wraps around the camera allowing it to be attached on the top rather than the bottom. Click on the picture to the left to enlarge. You can buy the aluminum bar at most hardware stores, cut it to length with a hacksaw, drill the holes, and bend it using the vise. Make sure the top hole is exactly above the bottom hole, otherwise it becomes off balance. Use a ruler to make measurements. You'll lose about 1/8" of an inch in the bend so be careful and account for that. It's also much easier to get a controlled bend if you make a little notch with the hacksaw on the inside where each bend should be.
