Okay, I screwed up. I am making a rail and stile cabinet side, using dominoes to hold it together. I put the domino holes right in the middle, forgetting that I was also putting the plywood panels also right in the middle. But, I am not sure it really matters.
I put a domino in and it feels pretty secure; it doesn't lose any gluing surface on the faces. Should be just as good as if I hadn't screwed up, doncha think?.
The wood is 1.5" wide, the slot for the plywood won't be deep enough to interfere with the dominoes on the rails.
