@workshop_companion: Over my woodworking career, I have designed dozens of these tools for the books that I’ve written. A few have proven to be extraordinarily useful; consequently I’ve made them over and over again, refining and simplifying their designs. I’ve gotten them to a point where you can make them from a single piece of scrap wood quickly and easily. I’d like to share these with you hoping that you will find them as safe and effective as I have. If you'd like to have the digital plans and full-size templates for the tools I show, they are available in PDF format from the Workshop Companion General Store at: https://workshopcompanionstore.com/products/safety-tools-plan
