I've been given a Sears 932176 dado blade set. I think the set is complete, it has 2 circular blades, 4 thick chippers, 1 thin chipper and a few thin paper washers. I'd like to know how these pieces are put together.
To cut the widest possible groove, I could put all the chippers between the circular blades and mount this stack on the saw. But the teeth of the chippers are wider than the rest of the chipper. So I don't understand what would prevent the side of the tooth of one chipper from striking the back of the tooth of another chipper. Is the nut on the shaft supposed to press the stack together so hard that the chippers don't change their relative positions? Or are there supposed to be metal washers that are mounted between the chippers?
