I am new to this forum, but I wanted to share a project that I have been working on. Below are images of a collapsable time-lapse dolly that I built. Many of the working mechanisms are similar to that of the Dynamic Perception Stage 0 Dolly, although I tried to make it smaller, and easier to assemble in transport. The overall track is made of 3, 2ft sections that latch together to make the 6ft extrusion. I also tried to come up with a new method to attach the timing belt to the ends of the extrusion, you can check out some images of my solution below. I am still working on creating a case for the DollyShield. More images are available at: design.isaacblankensmith.com There is also a video of the assembling the extrusion here: http://vimeo.com/34678262
I am happy to share any parts used and answer questions.
Let me know what you think!
