Vimeo member Fred Norquist used a bit of Angled Aluminum and old skateboard trucks to get this DIY dolly result. Looks like a pretty low budget DIY for those who want to add some movement to your camera shots and not spend a ton of cash. Although pretty effective, just by looking at it, there's a lot of variables with how the rails are positioned that can cause some irregular movements. So if you attempt this, make sure you got things lined up well. The old measure 10 times and drill once routine (I have to measure more than twice). Simple and effective for a DIY project i'm sure most people can tackle.
