I have never made box joints. I always thought they were done on the table sawAlso, on this cherry case, as opposed to the oak ones in my earlier post, I offset dado cut the ends before cutting the box joints with jig. That way I was only cutting box joints through half the width of dimension lumber. My short router bit could not cut through 3/4" oak lumber in the other boxes I made without two passes. The box joint cuts were consequently not very clean. And the cherry lumber was actually 7/8" so definitely needed to do something else. The result was interesting in that the sides had classic box joint appearance while top and bottom show dado joints.
