Summary of solutions to 22.5 degree cut

Thanks everyone for solutions, questions, etc. To recap:
1. Ed's SketchUp at #16 correctly illustrates the goal.
2. The Tenon Master Jig for a vertical appears the optimum solution, with the table tilted 22.5 clockwise, stock and Tenon Jig on the downside of the table, right of blade. I will want to check clearances carefully. Also, the piece is only 20 inches long (and 4 inches wide), so the Tenon Jig should accommodate the piece satisfactorily.
3. The raised panel jig is another alternative. I've been wanting to make that jig anyway. This is a good time to build it.
4. The idea of building a jig to hold the piece flat on the table and achieve the desired angle of cut seems doable, but not as attractive to me as the vertical cut solutions. If my piece were to long to use a vertical cut solution, then I would explore this idea.
5. Finally, a shooting board solution. I mentioned that the hand saw/shooting board solution came to mind early, but I was holding out for a SS solution since I cling to the idealist notion that the SS can do anything.
Great input. I benefit from everyone expertise. Thanks so much.

I sort of remember this discussion, from about a year or so ago, and the impression was that there are some things a table saw shouldn't try to do, and there are probably good reasons why noone has tried to make one to do those things. (When planes are banned someone will.)
But it's still an interesting mind game trying to visualize such a maneuver. Why one would want to doesn't really matter.
This also tends to remind me that I read (possibly in that prior discussion) that in the age of Shopsmith's birth and before, tilting table, not arbor, was the norm (not you, Yankee).

Not sure what is being made by joining the two 22.5 degree angles, but something similar could be obtained by making a 45 degree miter cut and then joining that to the surface of a flat board. The included angle also would be 45 degrees. It certainly would be easier to set up and cut. Making a flag display box would be one place where this could be used.
