JFC!!!

Post number 30 is correct, and that is the entire problem.

To get it to fit correctly, you would have to rip down the raked (slanted) piece on the left to reduce its width. But if you did that on a profiled piece of molding, it would not look right.

So you would need to add a triangular piece to make the corner transition.

I can sort of understand in theory how the triangular piece would be cut, but actually doing it as a practical matter on the saw...that's where I'm struggling.

This video just made me drool in stupidity. I don't really understand it, because I'm no rocket surgeon. Well, I understand the first part, but when he starts drawing the profile lines...holy shit...

Have a look if you want to challenge your brain...
