Gauge prevents planing problems

Anyone who has planed down stock to different thicknesses knows the frustration of planing material too thin. To prevent this, I created an accurate thickness gauge by routing and labeling ¹⁄₄ ", ³⁄₈ ", ¹⁄₂ ", ⁵⁄₈ ", and ³⁄₄ " notches in a piece of plywood. It's proved to be faster and more accurate than a ruler.
