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.
