"I have a prototype sugar powdering chamber" My neighbor just brought the 'duster' by, this might be the easy answer. It has a wire coil that will scrape the sugar though the screen. Its called the Powder Mill Model 76900 Dust Applicator by PlantMates, Inc. It has a good size hopper and Shane said he used much less powdered sugar. He also said he took out one frame and inserted the rather wide nozzle. We are going to try it next Tuesday. He said the store was Tractor Supply Store, a franchise (Northern California), for under $13.00. Janet . -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
