That spinner was Moving!
Is your target designed to flip up and stay up or swing thru the arch and lay back down? I actually like the idea of it not staying up! It limits the time you have to shoot at it!
One i'd like to make is a tire, with a target in the center, on a ramp off to the side. You just pull a stopper and the tire rolls across the range! It's simple and looks like a lot of fun! You can adjust the ramp for speed and put up boards to limit the shooting window!
That spinning target is pretty cool. How do you get the clay targets to stay on?
