I’ve been working on some electroGrav theories and am now wanting to start building models to try and test these theories. I’ve a 8ft satellite dish that I was thinking on using as a mold, but have no good ideas on how to go about this. As like a “UFO”, I need to create a top and bottom curved section then mate the two parts together. I’m not sure if it can be made with wood, plastic, fibreglass or ceramic... Anyone with ideas?
