Modified Camera Dolly
Here we modify an inexpensive tripod dolly and hi-hat with RigWheels to make a multipurpose track dolly. Three standard filmmaking tools combined for use together. What makes the build so easy in this example is that the caster for the tripod floor-dolly is attached with a bolt that passes all the way through the metal tube of the collapsable frame. The castes can easily be removed and replaced with RigWheels. The second tip for this build is that you can attach a camera hi-hat to the tripod dolly to get great low-angle dolly shots.
