Hi I'm interested in measuring the recoil force of a weapon. Anyone got any ideas om how to go about doing this? I was thinking of using a load cell mounted to the weapon in the horizontal plane, but at the same time the weapon needs to operate more or less freely, which will be difficult with the weapon mounted to a load cell (not very much travel there). I was also thinking of mounting a spring between the load cell and weapon to allow for more travel of the weapon, and this is more or less this idea I'm working on now. Will this work and give me the right measurement? Will I need to know the exact spring constant and distance travelled and do some calculations, or will the load cell reading be the correct one regardless of the spring?
