EMDO employed a Gardner G-Series double disc grinder from Landis Gardner for roughing and finishing stepped connecting rods, which have different thicknesses at at the crank and pin ends, as opposed to uniform thickness co-planar rods.
EMDO used the Gardner G750 horizontal double disc grinder with a reciprocating fixture because of its exceptional performance in achieving close tolerances--50 millionths of an inch.
For the prototype operations at EMDO, Ford selected 30" dia disc wheels.
To produce the stepped-down pin-end thickness, EMDO finish grinds the whole rod to the larger thickness of the crank end, and then re-fixtures the rod by holding it from the crank end to finish grind the smaller thickness of the pin end.
