Apart from its basic use to make length cuts, a radial arm saw can be used to create moulding, provided you know the right way to do it. Decide which shape you want the moulding to be in. It can be oval, square, oblong or any shape of your liking.

Now you need to angle the radial arm saw blade so that it can make cove cuts. Carefully, rotate the blade and bring it to the desired angle. Since it is cove cuts the saw is supposed to make, the angle at which you set the blade must be less than 90 degrees.

Lock the blade in place after lowering it onto the stock. Keep the stock parallel to the ripping fence and slowly run it through the saw blade. The blade angle and depth of the cove are directly related to each other. Wider the blade angle, steeper will be the cove cut.
If you want to cut compound coves, use the same technique with numerous passes.
