This is a 45 degree miter sled designed to use standard 3/4" x 3/8" miter slots. Can be used with any tool that has a standard miter slot.
I've included two models -- one with clamping sides that are about 7" long, and one with sides about 4.5" long for smaller machines (I use my smaller one on a Rigid oscillating belt sander, and the larger one, while a good side for the band saw, is too big for the sander).
The author marked this model as their own original creation.
