Nylon Spur Gear for Spider Center Diff

Update on the modified spur gear:
It broke....
The end that the bearing goes on snapped off due tothe nylon being to thin (because I had to dremel out from the center). In order for the spur gear to be strong enough I would need to have some sort of spacer/extended diff cup so that I wouldn't need to take out so much material from the spur.
If I figure anything out, I will post.
