Lost wax casting

[cymap]

Hi all, I'm new here so take it easy with me as i am a total noob. Anyway I want to try lost wax casting to make some rings to start with and I cant seem to find a seller of sprue bases . I have looked on the site and cant see any. So does anyone know where to get the rubber sprue bases and flasks that you put the investment into . Thanks very much in advance, Mark
