@5cd027e0 is it free-standing? What color are you planning on building the guillotine? Will it be visible from the street level? Have you had an engineering review on the design of the guillotine? Do you have insurance in the case that someone accidentally harms themselves with the guillotine? Can everybody have a guillotine? 

 @6b1b8e04 hmmm... insurance for non-accidental harm might be the sticking point here
