All of the winnowers out there seem to be either very expensive (for a relatively small producer) or a homemade series of tubes and a shop-vac. Even John Nancy's Aether (and I am a fan of his) is a bit costly for a series of pvc pipes, poly-carbonate, and aluminum. I'm wondering if anyone might have drawn out plans for a winnower that they have created that I can use to build my own? I would, of course, be willing to pay for these plans (providing they are a proven design, are written clearly and can winnow, EFFECTIVELY, 50-75 lbs an hour).
