Good results and more understanding from the last range of tests, best result was 16kN pulled to destruction. A step up from Mk2 which got to 12kN.
Not bad for a basic stainless steel, next step is to use a higher tensile stainless steel.
The form showed many improvements: it’s lighter and the deformation was more even showing a better distribution of force so less excess material.
Also trialed 3 different pin types with some interesting learning there.
Next up is a drop test and more material research.
