Can I safely change the size of my arbor nut for a dado stack?

[Caleb Larru]

I have a G0651 table saw and recently purchased the Freud SD608 dial a width dado set after being assured by Rockler it would fit on my saw. Everything fits except for the arbor nut. It is too wide to fit into the dial shoulder. If the nutt was a bit smaller it would have plenty of of threads to tighten down.

My stock arbor nut is approx an 1.5" wide. The Freud stack calls for an arbor nut less than an 1.1875" (1 3/16"). My question is would it be safe to use a smaller arbor nut (if I could find one) on this dado stack? One of my concerns (other than killing myself) is that arbor nuts are usually made of softer metal so that you don't strip your arbor.

Am I missing the forest for the trees?

My Delta UniSaw arbor nut is only 5/16" wide.

I don't think I explained it correctly. I should have said the diameter instead of width.

I would think that this is more of a result in how tight you make it, rather on how soft the nut is to prevent it.

Any nut that would fit the dado shoulder should be OK.

Make sure you're not installing the arbor washer with the nut. You only need the nut with the dado stack. That should give you just enough room for the dado stack.
