Let us know how you get on with it @cmennell42. It would be interesting to know how to do this mathematically.
I once tried to recreate this linkage in Kangaroo 2, inspired by the clock Solstice Clock by Matthew Gilbert (very nice btw):
It was modelled using a polar array of the ‘kinked leg’ bits. It kind of worked. although I probably need to tweak the strengths. If you’re interested in linkages (or anyone reading this), K2 gives an alternative approach in gh that gives a nice understanding of how these systems work - however as above, it would also be nice to know an analytical solution/equation. Maybe the polar array component might help you anyway, as in this definition.
