Topic tags/keywords: table saw dado blade

I have Sawstop 3hp professional cabinet saw. Max dado set width 13/16”. I am try to put 3/4” (12/16) dado set but when loaded on arbor with flange there are only a few threads left on arbor to hold the nut. Is this safe? Do I omit the flange and just use the nut? Any solutions to this problem?

Threads should extend past the nut.
What does SawStop say?

Per the manual:

For dado widths larger than about 3/8 inch, do not use the arbor washer. Instead, tighten the arbor but directly against the dado set.

Manual PDF

See page 29.

I had a similar moment on my jobsite saw (not saw stop) and thought I am not comfortable with this. I ended up making multiple passes. It is nice to know that I can get that last blade on when its close.

The nut should be completely on the threads.

Never looked at a Sawstop in detail. I can’t tell from the PDF from above how thick the arbor flange is. On my Unisaw the arbor flange and nut is all one substantial piece. I found using a fender washer gives a larger surface for the arbor nut too hold the dado stack on the arbor. Whatever you do, do not spin that wide of a dado blade without the full threads of the arbor nut in place.

Only because I’m desperate for something to do in the shop, I measured the SS flange washer thickness. It’s 3/8”. I had bought the optional nut for my Uni when I had it that had the attached washer, it was a nice addition. However, that set came with a different nut for dado sets that didn’t have the washer on it.
