*Ko-Ko: What are you talking about? I can’t execute myself.
Pooh-Bah: Why not?
Ko-Ko: Why not? Because, in the first place, self-decapitation is an extremely difficult, not to say dangerous, thing to attempt…*
I believe there was an Agatha Christie story which involved a person supposedly committing suicide with an axe. One of the characters was skeptical and said something like, “Splitting your own head open with an axe sounds like it would take some practice.”
Properly speaking, yes - but we don’t refer to someone being de-torso-ized, or some such. People are decapitated - despite the fact we know better, the English language seems to view the torso as the person, and the head a constituent part thereof.
It seems rather pointless. The tradition, going back to the ancient Romans, is that you don’t get full style points unless you use the sword to disembowel yourself …slowly. Apparently managing it with one quick slash will only result in partial credit.
I am reminded of a story told by H.L. Mencken about a German emigrant in Baltimore. He decided to end it all, so he went to a bridge and climbed on the railing. He then put a noose around his neck, took poison and shot himself in the head. He said the police were impressed with his thoroughness.

Using the same princible as the performer who spins plates on dowelsticks, you get a heavy blade swinging around a central pivot. Very heavy, so as to build up momentum, and a short though sturdy stand-in for the dowelstick, so you can crouch under the path of the blade while you swivel it. Then you stand up with your neck in its path, and finish the project ten inches shorter than when you began.
I know this violates the OP as a simple machine, but then anything you use to cut off your head is a simple machine: a wedge.
On an old episode of QI, Stephen Fry discussed King Goujian of Yue. The front line of his army was composed of condemned criminals, who would charge the enemy, and intimidate them by cutting their own heads off!
I reminded of a guy who committed suicide with a power drill. He had to drill himself in the head six times before he was dead. That’s determination - a lot of people would have quit after drilling three or four holes in their head and tried something else.
