Hey, I know you meant your comment in all kindness, and I hope you’ll take this in the same way; “females” is kind of a not-nice way to refer to “women.” Men who have a lot of contempt for women have taken that word and run with it like they stole it, and now a pretty big number of us get a bad taste in our mouths when someone refers to us by that word.

Your commnt is like a year and a half old, so you’ve probably learned that by yourself by now, but I guess I’m in one of those moods where you respond to year-old comments and go “Hey man…” today.

You could try a regular blade and a jig to take multiple passes that add up to your dado/groove. MicroJig makes the Dado Stop, but you can make something similar yourself, too. May not be as clean on the bottom.
You can also just buy a dado blade built for 1/2 plywood from infinity tools.

I just do 1/4″ deep by 1/4″ wide- regardless of if the plywood is undersized or not.
