Hy Guys
Here are the pics, they are a little blurry, but I think you will get the general idea. The balls are made of wood, aprox 1,inch round but you can get other sizes, and also in polystyrene, you can use Easylight/ Plastic Padding for the neck, and the loop at the top is 1/8 split pin. The boat is a bit dusty as its on the shelf in the workshop.
Hope this helps.
