Abstract: An alignment device for a portable motorized miter saw may allow a user to easily reproduce cuts of the same length, even when the miter saw is taken off and replaced back on a portable miter saw stand. The alignment device includes a three piece connector that allows for easy set-up of wings on either side of the saw, which are used to support the material being cut. Because the wings attach directly to the saw itself, the wings stay in exactly the same relationship to the saw blade. Thus, when a stop is attached to the wing, material can be cut to the same size lengths, even though the saw may be taken down one day and set up another day.

Abstract: A cushion back cutter is formed from a first side plate, a second side plate, and a center plate between the first and second side plates. The center plate includes a slot that forms a blade holding pocket with a bottom opening to receive one or more blades.
