Your way over thinking this. Just change the breaker to a single pole and replace the receptacle with a 120V. Reuse the existing wire. You will have an extra conductor but that's okay just cap it and move on.



You may be way oversimplifying it. We need to know if he has a neutral or not to determine if he can properly wire a 120v from the 240v circuit. It is likely he does but not guaranteed. Also, I thought he still needs 240v from the circuit, maybe I am wrong.

I will still need that.

I disagree, if he has an existing 240V circuit then he has at least 3 conductors. That would be sufficient for H-N-G 120V circuit. He just needs to make sure he sizes the 1 pole breaker correctly for the wire size.
