That test is also pointless, as there is no “control of parameters” during each test.
i was just going to turn up a “fake” steerer tube, mount a fork in it with the headset bearings, clamp that whole lot in a vice, and hang weights off the axle. say 10, 20 and 40kg, not enough to get any plastic deformation, and do that at various “extensions” of the fork.
The exact method doesn’t matter as long as it is repeatable, as all i am trying to do is actually compare forks, not rate them in absolute terms.
Could also use a dial type torque wrench to apply twisting force to the axle and measure the forks torsional stiffness etc
