This video shows my jig and a technique that can be used to cut box joints (finger joints) on a radial arm saw. No fancy gears, wheels, or cranks here--just a simple and intuitive method using blocks as shims to control the finger spacing. This technique is limited by the maximum height the blade can be raised (about 5 inches). However, the wood can also be flipped and cut from the other to extend the box width to nearly 10 inches wide.
