I need to create or buy a sphere approximately 2' in diameterIt must be sturdy enough to support plaster molds or foam filled castings of human arms plastered to the surface as if radiating from the originOptimally, the arms have to be attached well enough to the sphere to support it from the groundI am open to any ideas as far as the material of the sphere, the arms, or how to connect the two.
Use a big beach ball (they come in sizes up to 5 feet), place it in a plastic trash bag; then cover it in aluminum foil, tape if need bestand it on a round waste paper basket/ trash can; paint or trowel with fiberglass resin and cover with fiberglass cloth; cure, invert and repeatBuild up as many layers as you think you need to keep in strongYou must sand between layersFollow all precautions while working with fiberglass resinWhen cured you will be able to drill and bolt attachments onYou could make it out of papier-m?ché if your attachments are made of the sameThat would be a whole lot easier, cheaper and less toxicIt would be kind of like a giant pi?atasee video links below:
