Propeller table sculpture

Made from salvaged junk from my local scrapyard. The base is made a spun stainless steel half sphere..I found two of them but have no clue what they were from or for. The section on top of the base is ceramic, originally was used at a power station... also from the scrap yard, some kind of vintage propeller fan blade, there some auto transmission parts and a few other scrap yard finds.

Done
