Locate "wide" teeth fast

Determining an accurate blade width

Find the outermost cutting edge

With an adjustable dado blade (sometimes called a "wobbler"), it's hard to tell which tooth cuts farthest to the left and which cuts farthest to the right. Find the widest-cutting tooth--or teeth, in the case of the dual-blade adjustable dado shown--using a square. Then label that tooth's post with a permanent marker. Now you can measure from that tooth when setting up your cut.
