Your right jim-it took awhile to work this out but I think I got it. Here is a couple of pictures showing all the gears in place-



The 1/4" bushing is for the pinion shaft and that will be another reduction. I would consider this a low rpm motor -5000 rpm-12v. but a gear-motor will not work. It would start & stop instantly and that would cause the bucket to swing side to side. That is why I use a flywheel. It starts slowly and smoothly and does the same when stopping. I probably would not need the flywheel with an electronic speed controller but for now this will work.
