I guess the retainer is so thick because they have not idea what you're going to try and cut with it. Mine also is stepped to take different size ID holes so it makes it so you can't down the retainer too much. But why don't any of the affordable arbors have a Keyway to take advantage of the key slot in the saw blade? I wondered how much you could cut down the retainer if you had a key? Seems like most of the torque of cutting would be taken care of and it would take minimum thickness of the retainer. Knowing you, you have already explored this.......
