Measuring impact gun torque?

as well as playing with the springy washers.

For this you should use the best available friction modifier on the thread to minimise the difference between short sharp impulses and manual torque wrench, Tungsten Disulphide paste is best (but dificult to get, I had to import my stock) as it's coefficient of friction decreases at higher pressures, where Molybdenum Disulphide's coefficient of friction drops,
