Table saw dado jig

I made a dado sled and a fence for rabbeting with a dado stack if that helps

Here’s a link to a cross-cut sled that accomodates different sized dado stacks with a replaceable insert. And you can use it as a regular crosscut sled.

I made one and it works really well. There are pretty good instructions on the web page.

Make your self a bunch of inserts and then you’ll have plenty for whatever sized stack you may use.

You don’t really need a jig or fixture for making dados on the tablesaw. It is already set up to make that type of cut with a dado blade.
The above crosscut sled is fine if you need to dado narrow stock. However I usually need to dado the sides of carcass pieces, so I just use the rip fence to guide the cut.
If it is a tall workpiece like a bookcase, then I use a router and straight edge guide.
Good luck.
