Working on cabinets for the first time and going to have permanent shelves attached with dados. Cabinets are 30” tall and 13” deep. Trying to figure out how to cut the dados into the sides.

While I do have a router, I prefer the table saw. Mostly because it’s the tool I’m familiar with (have basically only used the router a few times) and because I already have a dado blade, but don’t have the bit for the router. Would prefer not to have to but it for this.

If I were to do this on the table saw, what would be the method? I’m assuming running it along the rip fence won’t work well because the workpiece is twice as long as it is wide. Miter gauge seems like an option, but doesn’t create much of a reference surface for the large piece. I have a crosscut sled, but the width of the dado would each into my fence, so don’t really want to do that.

Are there other table saw options? Or is table saw just not the best idea for this?
