40-430Kb These are of the Differential Hoist or N(N+1) alternative for power. The idea is that the greater amount of torque allowed by the slightly larger (1 to 5 more teeth) main gear allows for a slow constant drive. The Explaination file is an Acrobat file with both text and a numbered diagram, as well as building notes. 10/09/97
