Motorized small soil sifter?
Would anyone have a small motorized vibrating soil sifter for sale or know of any companies that manufacture one? A home-made one would be fine. By small, I suppose I mean suitable for a large garden operation with perhaps a screen area no bigger than 6 x 8'. I would like to use it for sifting soil and compost, but also for archeological digging. I am aware of plans for turning a cement mixer into an economical sifter, which is great for soil sifting but potentially damaging to artifacts, Hence the need for a vibrating one. Economical small industrial sizes, hopefully on wheels, such as used by nurseries are of interest, too.
