Submitted by YouTube member detomaso4ag, here's a simple method to create your DIY Mini Video camera track dolly. For those who don't mind the skate wheels on a pipe track it's a cheap solution to getting smooth gliding camera movements. The trick is getting the wheels drilled in perfectly to the angle iron. If you're slightly off, then the dolly will wobble down the track. For those who aren't ready to tackle the DIY, these mini dollies already exist, found below.
