At-a-glance grinder gauge

Here’s a simple way to reset your grinder’s tool rest to the correct angle. After adjusting the angle just where you want it, lay a scrapwood block on the table alongside the grinder wheel and trace the curve of the wheel onto the block. Saw just on the waste side of the curved line, and then “grind” the shape of the wheel into the curve for a perfect fit. Next time you need to sharpen that tool, use the block as a gauge to position the tool rest.
