In the past I have used a router to cut across the grain on the table top, protecting the end from tear out several different ways. I started off cutting the groves in the end pieces using the table saw and slowly moving the fence until I reached what I wanted. I bought a Frued dail a width dado and started using it. I was about to pull out a router and start setting it up. Then I had a thought, scary. Why not use the dado set to cut the cross grain top cut. Will this work or am I missing something? I know, make a test cut. Since I am just returning to woodworking I do no have the usual stash of left over pieces to do this.
