I forgot to mention, if you look at the pictures, the bull gear is held into place using a set screw in the end of the gear (#14). I didn't have it screwed all the way in, in my first pictures, but the gear sits at the very end of the shaft. Half of the set screw teeth engages the shaft, half engage the bull gear so the threads have to align perfectly or you can't install the set screw.
I found this, seems to be an interesting read.
