Ratchet drill
From Self-sufficiency
Home-Made Ratchet Drill Secure a gear faun an old clothes wringer and fit it over a piece of ½-inch pipe which has a coupling screwed ower on one end and is cut square off on the other. Thread a piece of ½-in. round iron, place a nut on it and insert in one end of the pipe. Bend a piece of strap iron to a "U" shape and drill a hole in the ends so it will fit over the pipe. Bend an eye in a piece for a dog and fasten it in the leaver with a cotter pin as shown. Then attach a small spring to keep the dog engaged in the teeth of the gear.
