Connecting the engine to the gearbox and the gearbox to the pinion stand are two large diameter solid steel shafts.  To get the mill to fit into our limited space, both driveshafts must be shortened.  

Currently the gearbox to pinion stand driveshaft is at Mandrel Group in McDonald, OH being shortened ten feet.  The much longer engine to gearbox shaft also needs to be shortened by approx. ten feet.  

Connecting the engine to the driveshaft involves the creation of components to adapt the universal mill coupling on the engine to the flange coupling on the end of the driveshaft.  We have designed a new coupling and spindle based on the original William Tod designs. 

The new design for the universal mill coupling that would be bolted to the end of the shortened driveshaft.  A new casting must be made and machined to create this part.
