New saw, new (Delta) dado set.
Instructions say not to use the outer blade flange but rather to tighten the arbor nut against the outer dado blade.

Really?

If I’m cutting a thin rabbet or dado and the outer blade flange will easily fit on and the arbor nut has plenty of thread extra, should I really leave the flange off?

I haven’t used a dado set…. haven’t set one up in so long I can’t remember leaving the outer blade flange off.

I may be wrong, but I suspect that instruction is to protect themselves against a lawsuit by some idiot who tries to use the flange when there is not enough free arbor to get a good bite on the threads. I can’t imagine any harm in using it if you have room on the arbor.

I’m just speaking for myself and using my own common sense, but when the stack is small enough for using the flange and nut safely (meaning having plenty of thread for the nut) I use both the flange and the nut. Otherwise, if there is not enough thread for the nut when using both I use just the nut.

I’m with Charlie and helluvawreck (aka Charlie…:),

Go for it….I do it all the time…......If I got the room for the flange and nut, that’s the route I take…. just use your common sence, and if it is safe, go for it….Now if you go 3/4”. or 15/16”, don’t even think about it…

A contrarian vote to follow the manufacturers warning. Your stack will work fine without the flange – and if you never use it on your dado set, you’ll never have to decide if you should or shouldn’t.

If your not supposed to use it, Why do they give it to you when you buy the set ?

I use the flange if there’s room, and I don’t if there’s not.
However, I read an article once about this. It has something to do with the potential for a blade to slip with the flange on, supposedly. This would do no damage to your saw. The article suggested that the slipping blade could possibly damage the teeth of the blade or chipper.
Now, after reading this article, I rushed right out to my shop and put my dado stack on my saw and took a good look at how things mesh if the blade did move. I see no way it would possible do any damage.
