I wanted to try snow making as a project this year, but after looking through most of the parts list I think it might be a little bit expensive. Even if I did one of the cheaper designs I would still need an air compressor and from looking on line they seem to be a little expensive for me. Besides that I don't think that I can justify buying one just for making snow.
Another item that looks like its required to make any good snow is a pressure washer, that is another small fortune. I guess I could see if I know anyone in the area that I could borrow the parts from and just assemble it from designs on the web.
