i have thought about building 2 plants my self, 1 from a old small propane tank in to a trommel and another a small shaker deck that can handle about 20 to 25 yards an hour, it is a nice operiaton, wish you had better access to water, if i was not back to work i would come out and help.
Looks like are really nice machine and appears to be low grief. I am curious how is the recovery on the system? I had a chance to use one out in the desert a few years back but we never had a chance to check on the recovery. The machine worked very well then as well
