Dry (waterless) Jig Part 1

Video of the waterless mineral jig I designed, and some of the experimentation as I went along. EDIT: 1/30 2016. The further development of this unit for gem prospecting has been a big disappointment. I do not recommend anybody build any version of the the dry jig in the hopes of using them for gems. They work fine for gold, however. Development work is ongoing. Jim
