I saw a TV show where a guillotine was built with a blade that swung in an arc so that multiple people could be executed at once. As an added bonus there were nice ratcheting noises as the blade was cranked into position.
The right side of the blade is too narrow.
We'll have to sort them by neck thickness.
Would one head be fully severed before the next neck meets the blade? I'm worried the increased resistance would stop the blade.
At this point, wouldn't a horseshoe shaped contraption with a swinging blade be more efficient since it requires less material for the blade?
Sure, but you have to have enough momentum to cut through 15 necks consecutively. Spines do provide a considerable amount of resistance that must be accounted for.
Either big springs or big weights would work.
