Latest test on the LRBP Mk3 achieved 16kN. A great improvement on Mk2 which got to 12kN. This is with a common stainless steel, next step is to source a higher tensile stainless steel.
The new form worked well distributing the distortion more evenly which indicates less excess material, Mk3 being lighter.
Also some interesting learning about the pins this time trialing 3 different types and seeing the failure mode.
Next step is materials research (easy to find a good material but harder to find a supplier in Australia: one of the impacts of offshore manufacturing).
And a drop test to see how it performs in a simulated extreme climbing fall.
