You're welcome. I learned something myself in that video where the woman centered the joint making multiple passes on each side of the piece. Very cool method. And it reminded me why the TS sled is such a useful and safe way to cut.

I have used that method but using my radial arm saw. Now that I no longer have it, it can be done using it's replacement, the Bosch 12" glide saw.

I've also made one-offs with my sliding miter with a glue line blade installed, yet I've always had to clean up the bottom anyhow.

If I were doing lap joints as you're using them, I'd also use a dado and shoulder plane. Here's a video on making face frame lap joints on a table saw WITHOUT a dado blade. If you have a glue line blade you'll get a pretty flat surface. The method for setting up the actual cut to get a perfect overlap is simple and elegant. This is probably the way to go if budget is an issue. https://www.youtube.com/watch?v=Klpn-LutJf8

Theatrical flats are now made using lap joints, and are almost identical to a face frame, but with much wider material, then covered with muslin or a light canvas. The canvas is stretched and shrunk and addes strength and durability so they can be reused for decades. Those joints are made with a router because they are about 4x4 inches in area. The crosscut edges are usually precut with a hand saw to help avoid blowing out the edges of the joint. In a theatrical flat, the joint doesn't have to be as near perfect as it would in a smaller face frame, thus the final fitting with the shoulder plane for a face frame.

Here's a video of making a flat, somewhat similar to what you're doing, but using a router. https://www.youtube.com/watch?v=Pq5TScibuHQ

The lady of the first video needs a BETTER DUST COLECTOR. IMHO

I didn't notice that you were making frames, I thought you were making doors. BUT as been pointed out pocket holes are the way to go. For simple cabinets, they are the perfect solution for both strength and speed. For that matter, you can build the whole cabinet using pocket holes. If you don't have a pocket hole jig get one. IF you don't agree that they are the easiest and best way to go then take it back. I'm sure that you will still be using it 20 years from now.
