   That is a light duty variation of what I am doing.  I'm using a pair of   
   12000lb drop foot jacks that have input shafts on both sides.  My plan   
   is to link them with a sprocket on the linkage.   
   --------------------------------------   
      
   I bought a motorcycle transmission output sprocket to drive the Kawasaki   
   rear wheel on my sawmill, and didn't notice that it had 13 internal splines   
   which made indexing the shaft cuts difficult. A 52 tooth change gear from   
   the AA lathe solved the problem.   
      
   The sawmill head lift uses two bicycle sprockets connected with plated   
   chain. Their Sturmey Archer style rounded drive lugs were also somewhat   
   difficult to adapt to threaded shaft hubs, from measurement difficulties.
