Cutting stopped grooves or rabbets
Here's an easy way to form stopped grooves or rabbets. Draw a line on the saw table where a blade tip at the front of the blade passes through the insert, where shown on the drawing. Then, draw a line on the part where you want to stop the groove or rabbet (for example, 21⁄4 " from a leg's bottom for the stopped 1⁄4 " groove). Now, cut the groove, stopping when the two marked lines align. The blade will leave a radiused area at the stopped end. Square it with a chisel.
