Introduction and materials
Because we tend to be focusing more and more on videoing Buildeazy projects, we try to improve production as we go and occasionally we get – or make – a new tool to help.
“A track dolly would help”, somebody said. Mmmmmmmmm, I don’t know if we’d use one all that much, but sure would be fun to make. And 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 Polyvinyl chloride. A common thermoplastic resin, used in a wide variety of manufactured products, including rainwear, pipes, garden hoses, phonograph records, and floor tiles. 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 throughout this project are given in both Standard (inches) and Millimeter measurements. (Abbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch.). 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.
