Now that I see what you are trying to do, I think you're poor boy approach is quite good. Make the temporary fence and rip it from both sides. Sure would be good to have a reliable helper for this operation.

To rip a 4 X 4 takes a 12" cabinet saw. I have a sixties model Powermatic, 5HP, 12" that came out of a high school shop. It has a Biesemeir fence added. It and a couple of rollers on stands that I have, would make short order out of that job. Wish you were closer.
