That is what i want, so i was thinking. What if you buy a bearing that has a 1 inch bore. Like this from mcmaster.com 60355K19. Then cnc or make a 1 inch bushing with a hex in the middle of it. Press fit the bushing into the bearing and try as hard as possible to not mess up the bearing. This way the sprockets and the gears can all be hexed @ the same size.
Or
Take the 1/2 inch hex and mill it down to a 3/8th's. Leaving a 1/2 inch circle for the bearing in the middle. I'll try to put up a drawing to illustrate what I mean. Sorry for the vagueness.
