I have seen several times over the years online posts about how to make a DIY camera dolly that uses PVC pipe as track. It came up that I could use a camera dolly recently so I put one together and it is great!
There are many many tutorials, guides and videos online explaining how to create one of these, I took inspiration from these…
I used some thick plywood as the platform, then mounted inline skate wheels to aluminum angles, then attached those assemblies to the bottom of the platform. To take the thing to the next level I affixed some indoor/outdoor carpeting to it. The entire project was pretty easy and the results are fantastic.
Here is the finished edit of the video I did for PacWest, there are a few dolly shots in there: http://www.vimeo.com/6299207
