would washers tied to each end of say a foot long piece of string work?
have nails hammered into a board at a slight upward angle, then hook the washer over the head of the nail.
On second thought..., i bet the clayoreo would want to spin.
So one shooter sees the full 110mm diameter face of the claybird. Then the next shooter gets stuck shooting at just the edge.
That's why the duct tape. It lasts for a number of shooters before someone shoots it until it breaks. It keeps the oreo face on to the shooter, and it really doesn't even move that much in the wind. We used little twigs at He-Man, instead of buying toothpicks...I used a 2.5 inch screw for a local match to put in the tape and it made it through the whole match!
It doesn't need to be all intricate. At He-Man, I stapled one piece of duct tape and just taped the other, and they seemed to both work just fine.
