How lucky is [Transistor Man] that he found the materials for the tracks of this curved camera dolly just lying around the shop? The three rails making up the system are quarter-inch diameter and he was able to bend them by hand with the help of a 55 gallon drum. But to hold them in place so that the camera dolly would run smoothly he had to find a way to precisely space the tracks.

The robot arm you see in the picture above is a 3D printer which ended up being the easiest solution to the problem. With a bit of trial and error he found a design that holds the tracks in place without interfering with the camera sled’s progress. From there he devised a mounting system which uses three camera tripods to hold the track. You can see a test video shot from the dolly track embedded after the jump. It’s the opposite of the bullet time rigs [Caleb’s] been working on lately.

We figure the spacers would work for any track shape, but if you’re going for a complicated route you need some type of pipe bender to help out.
