I'm trying to build a 'Beauty Dish' for photography. I need to source a large 20+ inch diameter somewhat shallow dish shape. A stainless mixing bowl is the perfect shape.
I can get large 30qt stainless mixing bowls fairly cheap, but with shipping it's still around $25. I'm thinking of local restaurant suppliers, but they are all a good deal more expensive for something that size.
I have been thinking of making something with foam core pieces cut to shape and hot glued together.
Anyone have any sources for solid dish shapes, bowls or better ideas? It does not need to be metal, but it does need to be rigid. I have all the rest of the hardware I need, I'm just missing the dish.
