A sticky solution for perfectly sized dadoes

Drawing of dado blade with finger putting four pieces of tape on dado.

Sometimes you need a fine adjustment to the overall width of a stacked dado blade. Instead of flimsy shims that can get lost and fall into the threads of the arbor, I use duct tape or painter’s tape on a chipper, evenly spaced around the arbor hole. Painter’s tape provides about .005" thickness, and the duct tape about .012" thickness.
