Back in the bad old days when I worked for a living, really back, we used to 
grind-plate-grind jugs for P&W 2800 and CW 3350s on planetary grinders. It 
was kind of strange at first, but worked OK. The spindle rotated one way and 
the grinding wheel spun the opposite way. You set the radius of the spindles 
rotation and the depth of the stroke. Every body called the machine "Wobble 
Annie"  Much later they got jig grinders that did the same thing but 
smaller. never ran one of those but was a lead for the guy who did.
