Hello Everybody, A good friend of Mine(and also My Mentor)uses a heavy duty variable speed drill to power His extractor.It is very simple to hook up and the cost is very low compared to the alternatives.This would be a very inexpensive solution for a hobbyist with just a few hives. I am not very mechanical so I don't know how to explain it, but it should be very easy to hook one up.good luck, Garry Libby Boston,MA USA [log in to unmask]
