Repurpose scrap plywood
Go through your collection of scrap plywood and cut a few little squares of each thickness. Every time you work with a new plywood thickness, cut a few squares of it, too. Label each square with its thickness and keep them handy. They’re great for measuring depths of grooves and gauging saw blade and router bit cutting depths. Pile up various squares to get just about any thickness you want. For many small measuring tasks, it’s easier to use gauge blocks than to use a tape measure. Thanks to Carl Griebel for this tip.
