>>HISTORY<<
Fall 2007:
Acquired grinder from a fellow OWWMer.
Accompanying the grinder was a GM/Packard 1/10hp 1750rpm motor with 1½" pulley.
The excessive grinder gear case bolt lengths caused interference with the hinged splash guard.
Added flat washers under the gear case bolt split lock washers.
The reduction gears were cleaned and new ball bearing grease applied.

03/02/2017: Added photos of full rig with motor moved toward back, away from splash zone.
