Hi - Has anyone built a feeder mechanism for a blue bowl, at the moment I run the 30 mesh material with the bowl running at about 3/4 inch below the outer rim, however when you have a lot of cons at a teaspoon at a time it takes forever.... I find the blue bowl very good otherwise as each teaspoon of material is is introduced the fine gold immediately drops near the outer edge and is easily recovered - a slow feeder mechanism would be better I think.
