Especially notable was Jerry's wobbler built as a machinist's challenge. He constructed it out of two 1/4" dia. X 12" rods, one brass the other S/S. It won first prize at the Black Hills Model Engine Show and placed second in the 17th Annual Sherline Machinist's Challenge. A couple of websites follow for more information on the Sherline Machinists Challenge. Note: That's a NICKEL lying on the model.
