How to make a Track Dolly [Table of contents below]

track dolly

Introduction

A friend getting into videoing ask if I could build him a Track Dolly.

"Why not?" said I. "Sounds like it could be a fun project." After all, that's what we do: make things.

A bit of research told us that there seems to pretty much be a standard method of building a D.I.Y. track dolly. It basically consists of a platform sitting atop a couple of pieces of angle aluminium (spelled aluminum in USA), with skateboard wheels attached beneath. The track dolly moves very smoothly along the tracks, which are a couple of PVC pipes.

Anyway, who are we to argue with the tried and tested? So we worked out the size that would best suit us and scouted around for the materials.

This is how you can make our version of the track dolly...

The measurements

The measurements throughout this project are given in both Standard (inches) and Metric (mm). The standard measurements are best suited to North America and the Metric measurements are best suited to Australasia and other countries. The inch sizes given in this project do not convert exactly to their corresponding metric (mm) equivalents, so use one or the other.
