Fast-change zero-clearance backer boards for your mitersaw

I like the clean cuts I get using zero-clearance wood backer boards bolted to my mitersaw’s fences. But bolting and unbolting those boards as I changed cut angles became a time-consuming chore. Here’s a better way.

First, bolt steel plates to your saw’s fences. Position them so they don’t interfere with any type of miter cut. Make wood backers from 12 " material and drill four recesses in the back of each for holding rare-earth magnets. Glue in the magnets using yellow woodworker’s glue—it holds fine but allows you to knock out the magnets when replacing the backers.
