Adjustable Dado Jig
Perfect dadoes every time! Easy-to-build jig lets you cut snug-fitting dadoes exactly where you want them—without having to use a cumbersome straight edge that can often come loose.
Simply adjust the jig to form an opening the same width of the dado and then clamp to your workpiece. Rout dadoes 1/2" to 1-1/2" wide in workpieces up to 25" across. This woodworking plan appeared in ShopNotes magazine No. 20.
