There is so much that goes into building a machine like this. If you are looking at making one a simple instructable isn't going to help you. This is more for the serious hobby miner with some fabrication skills. In looking at our machine you can see hands down the smallest (on youtube anyway) proven water pulse concentrator, some of the issues we deal with that don't scale down properly and how we overcame them. I will amend this instructable at the end of the mining season 2013 to showcase the newest changes and how they work. Buzz me a PM if I haven't done it by say October. In the videos in this instructable they start oldest and work forward so you can see what we did along the way.
