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): [SolsticeClock] 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 ni…
