Making long, straight and accurate cuts with a circular saw can be a challenge. Build this simple track jig that serves as a guide for your saw to help make straight cuts every time.
A circular saw is no replacement for a table saw, but this guide track will provide the same functionality for cutting long boards and sheet goods that a table saw and outfeed table can do. You just need to clamp down the guide track at the width you need to cut and let your circular saw do the rest.
It's best to build a 245cm guide track and then cut down the guide to smaller lengths as needed.
The first cut will be for the fence which will use the factory (straight) edge of the plywood, and the second cut will be for the base that the saw will slide along. You can then secure the fence to the base with glue and staples to finish it off. Check out the video above to see it in action.
