I have both the Freud dado set and Forrest King dado set. One I use for general cutting of dado’s, one I will use as a premium when it comes time to do fine furniture dado’s.
I’ve always had trouble with my Freud dado’s because I “thought” I read somewhere all teeth have to be offset from each other. This left noticeable high/low valley’s. Then I tried having the outside and inner blade teeth aligned and each of the cutters offset. Now, perfection of a dado. Is there a safety issue of having it done this way, of outside and inner blade teeth aligned while each cutter teeth are equally offset? I really do not want to think I solved the dado valley puzzle if I’m missing a safety issue.

I don’t align anything on mine. I just make sure the teeth next to each other aren’t hitting/rubbing each other.
Make sure the blade plates are flat against each other, (not riding on a tooth).

Outside lined up, inside just so the teeth do not touch

Is the arbor on your saw threaded almost all the way to the flange?

I agree with Iwud4u, I don’t align anything as long as no teeth are touching and the plates are flat against each other. I can’t see what the safety issue would be other than not having plates flat. When using only inner and outer they are certainly not lined up.

All the blades in a dado stack swing in the same arc, regardless of their tooth alignment status, assuming the arbor is true.

might have to one day, find out if my arbor is true or not. or maybe i have had issues with perfect flat bottom dado’s because i have a bosch 4100 contractor saw and not a true cabinet saw.

I just make sure it’s flat, but I did notice some messed up dadoes last time I used it. Maybe time to double check the ‘structions again!
