I was looking at some power saws on Ebay and on one of them they said that the saw was a worm drive. I dont understand this. Are the worms inside the saw? What do they do to make the saw work? The picture they showed had an electric cord on it. If the worms are driving the saw why does it need to be plugged in? Of course I know that sometimes Ebay sellers dont show the actual picture. Then, how do I feed these worms? They got to eat something. What happens when they die, can I order more of them, or can I get them from a bait shop? They sure come out with some strange devices these days, and I cant see how a bunch of worms would run around in there to make the saw turn, but if it cuts wood, thats what counts.
