Confusion with Ryobi tablesaw RTS30 and what to buy for Dado Cutting

I don’t own this saw, just wanted to put that out first.

I would believe that the limitation on a dado head of 3/4 would be a function of the arbor size on the motor. You should be able to fully engage the nut on the arbor. If you can do this with a 3/4 stack, you’re good. The QA on user manuals is not as good as it should be.

The adjustable dado, specifically the wobblers will really tax you motors arbor. They are naturally unbalanced. Your saw was built to be lightweight and portable. I can only guess that the motor and mounting hardware on this saw will not do well with such an un-balanced blade.

I’ve been using the Delta 8” and I’m happy. Search this site for reviews on 6” sets, you’ll get plenty of opinions. Your choice should be based on the work you’re doing, what results are acceptable and budget. You have lots of choices.

The 2 main things to consider is, one, can you fit a 3/4” stack dado on it and still fully tighten the arbor nut and, two, is the the throat insert wide enough to accommodate it. Throat inserts are easy to make to any size you need, so that is not too much of a problem. But being able to tighten the arbor is a huge issue and if you can’t fully tighten the nut then you are asking for some scary bad things to happen.
