I also use the Ridge Carbide, and it excellent. I used to have the Freud Dado King, which was quite good, but the Ridge Carbide is way better.
How do you like the cut quality of the Infinity Dadonator? Have you compared it to any other dado sets? I believe that it has 42t, correct me if I am wrong. I would guess that the Infinity would do great on plywood but might have too many tooth for dado’ing solid wood?
SawStop Dado Trigger Issue:
Hi: I am the guy that had an accidental trigger with a dado blade. The blade hit the miter gauge. And BANG! Very big BANG. Well, long story short, my dado blade had full-size chippers and the force to stop the blade bent the arbor and sheared teeth off the blade. It cost me $275 to replace the arbor assembly, plus $99 to replace the cartridge, plus the cost of the dado blade. And the arbor replacement took about 6 hours and required me to lift the table off the saw. But taking apart the saw was actually fun. The SawStop is an excellent piece of machinery.
So here is what I learned:
1. Don't use full-size chipper blades on the SawStop. They present too much mass for the saw to handle. It not only won't stop the blade as fast, but it can bend the arbor. Their web site lists a variety of "approved" blades.
2. I had 2 triggers before with a Freud and Forrest blades. I accepted that replacing the blade and cartridge was worth the money. But blowing out a $350 dado blade is getting pricey. So I went with a cheaper dado blade that had good reviews. And hopefully, it will not bend the arbor if it triggers.

Stephen, is your saw a PCS or an ICS? It looks like the ICS, which means that it has heavier works all around, right?
When it was triggered, did it take out part of the miter bar or do you think that had it been a finger, would it have been protected as well?
I purchased my regular blade per SawStop's recommendations, with no anti-kickback teeth.
My previous dado sets have been a Delta 6" carbide set and a Craftsman 8" that is chrome steel. I still have both but they are quite old. II haven't made any comparisons between them. Comparing to them would probably not be too meaningful because of the age. I have not used the Infinity much. The cuts are flat bottom which I like. I will be using it this week. I will try some test cuts across grain and with grain in hard and soft wood and some in plywood. I have some baltic birch and some poplar core birch plywood. I will also report on the number of teeth. The shop is about 1/4 mile away.
My shop tools have been in storage for about 3 years. I am building a new shop that is nearly finished. The construction work is on hold due to my fear of catching the corona virus so I have been moving tools in and getting set up what I can by myself. I have some building materials that are in the way. So for awhile, I will be limited in what I can do.
The Sawstop is new. I turned it on for the first time yesterday. I will have to learn how to change the brake cartridge to do the comparisons.
Just to be sure I was interpreting what type of cutter was not recommended, I chatted on line with SawStop. It is just the chipper disk with six chipping teeth that is the problem. I confirmed that the Dadonator is not recommended. The reason he gave is the extra weight might damage the arbor. Not only that, but if the arbor were damaged by triggering, it would not be under warranty. The service engineer would not answer my questions about reducing the rotational inertia by limiting the number of cutters on the arbor. He just said it was not recommended period and pointed to where the warning is published. He did not mention anything about the anti kickback teeth.
Thomas if you haven't read through these pages, you might when you have some time. They're written by one of the SawStop tech folks.

I have a Freud SD208 and the dado cartridge but I haven't used either yet. I used a 6 inch SD208 on a previous saw and it did fine so I am confident the 8 inch will too.
I have the ICS.
It just nicked the miter bar. I was holding onto the bar at the time. Even with the shearing of the teeth, it stopped that blade after about 20 degrees of rotation so I don't think I would have been injured if it hit me.
This trigger occurrence is like something that happened to me before while I was cutting aluminized foam board. It seems as though holding a piece of metal and hitting the blade with it allows the body current to pass through your hand into the blade. I guess it is how the hot-dog sets off the trigger.
I use the Freud Super Dado Set with my ICS. Has worked fine, and I actually triggered my old SawStop Contractors saw while making a zero clearance insert with it. It messed with the blade (which I had repaired), but did not seem to have any negative effect on the arbor. FWIW. And yes, it was an expensive mistake. But all digits were intact.
I also use the Freud Box Joint set, which works great with the iBox jig.
- After I ask a stranger if I can pet their dog and they say yes, I like to respond, "I'll keep that in mind" and walk off
- It's above my pay grade. Mongo only pawn in game of life.
I use the Dadonator on my ICS for flat bottom dadoes and finger joints. Excellent cuts in both ply and solid stock.
I wasn't aware of the "not recommended" status but the chippers are ~~inner 1/3 solid and outer 2/3s of the diameter "spoked". I've done full 3/4" dadoes with no worries. I have an estate sale aquired Irwin dadoe set that is not flat bottomed that I use most of the time to preserve the Dadonator. It gives good cuts as well but corragated bottoms.
I've had the Dadonator for 10yrs and didn't realize they are so spendy now. I had the Freud 6" set but needed an 8" set for the SS. The Freud had great cuts also. Good luck shopping.
I have a mint Forrest Dado King set I could part with. I bought it new and have used it once or twice in 15-20 years.
