The heart of the Tod McDonald Rolling Mill is the mill stands.  We saved five stands from McDonald Steel including No. 6 and 7 in this photo.  In these, a pair of 14" dia. rolls would squeeze and deform 2,000 degree steel into different shapes depending on how grooves called passes in the rolls were configured. 

The power from the drive motor was transmitted to the mill stands via a driveshaft to this pinion stand that took one power input and turned it into three outputs.  The pinion stand is in the middle with stands 6 and 7 on the left and a driveshaft bearing on the right. 

The power was transmitted through this bevel gearbox to stands 6 and 7.  

Removing the bevel gearbox base casting was the most difficult part.  It was firmly grouted in, covered with a century's worth of mill grease and weighed 28,000 lbs., over the rated capacity of the overhead crane that we needed to lift it with!  But good old DC Morgan cranes are incredibly strong and made this last big lift with relative ease.   Here we are using a mini excavator to break the grout out from around the base casting. 

The two driveshafts that we also acquired are on the right.
