I am trying to think of a cheap and easy way to test shotgun recoil with different loads, with some objectivity. Preferably something that can be done on video and make any differences fairly clear to viewers.
So, I have been thinking of building a white board to stand in front of, marked off in two inch increments with taped lines. Side view of shooter, same stance for each test shot.
Thoughts?

The Mythbusters would probably use a shooting sled with a fish scale attached to the butt sling, measuring how many pounds/ounces of force are exerted against the scale for each shot. But you did specify 'cheap and easy'.
As long as you can reasonably eliminate the possibility of the shooter's stance changing from shot to shot, your idea should work.

I have seen some handgun recoil (muzzle flip) photos taken against a background of graph paper (some gun magazine, years ago).
Great idea for a study! I would like to see it if you can work it all out.
Paul,
I was thinking of hanging a string vertically in front of the subject, to be touched by chest and forehead, and marks for foot placement. This should create the same stance for each shot.
Bulkammo.com is sending out various buckshot loads for testing. Low recoil, standard, and magnum. Now I'm trying to find a good way to do this that illustrates the difference.
I'd start by shooting the shotguns against a scale, some of the digital models have "peak" measurement settings. Then I'd set up tripods with lasers pointing at specific sposts on the shooter, like foot, waist, and shoulder, to ensure the same "Starting" position. Finally, I'd use a Canon EO 40d to get the 6.5 FPS it needs to show the shooter's body being flopped around.
Yeah, it's cheap until you get to the $1500 camera.
Sounds like a cool test, though.
If you watch Ebay, you can commonly find used USB load cells. They're pretty easy to use, you can download the software for them, they have a very rapid response time and work very well. You might be able to make a recoil pad that has the load cell built in, and use that even on different guns. You might even find a broken old digital scale and take the load cell out of it.Looking forward to the post!!
Interesting ideas Og.
I was going to use a video camera that should allow me to slow things down on replay, so that solves the $1500 camera issue (g).
I'll look into load cells. Never considered those.
I would go with your idea. It is simple in thought and design. But it the shotgun equipped with a recoil pad or not? Felt recoil is another factor. The shooter should be one individual.
