Well, more used to dealing with megaliths anyway. But it's all maths, innit - loadings, angles and coefficients of friction - there's a clear and certain answer as to whether it is currently dangerous I'd have thought. There are relevant academic departments in Exeter and Falmouth who might like to be asked for their opinion just as a fun exercise, not to tread on the toes of their colleague. But I'm fascinated by the idea of artificially constructed tenons and mortises. They might look like that because a nobble tends to settle into a hollow, but were they deliberately constructed? Would such a thing be necessary if the structure was intended to be buried? It's a fact that a capstone resting on three points (not 4) is extremely stable, would further engineering specifications be needed?
