I made a bunch of serving trays that way about 10 years ago. It's not for the faint of heart. Lots of ways to screw up and I found most of them.
Remember that each edge to be joined must approach the bit at 90 degrees relative TO THAT EDGE. The piece with tails must be attached to the slider at an angle so the angled end sits flat on the table (see image 249).
The piece with half-blind sockets needs a tapering jig to slide along with it against the fence. This jig is represented in image 252 by the red sandpaper. The jig really needs to be slightly longer than the workpiece and the jig needs a hook on the end to carry the workpiece along with it.
Now that I have a Leigh DR4R, I wouldn't use the Incra to make these joints, but if it's what you have . . . .
“We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore.” - Mark Twain
