Wow! That is small! Nice work!

I think that would fit just inside the tire or right on the tire. Very close. If I ever get around taking pictures of what I have in front of me, it will give a great picture on what I need.

Yeah, the hole size would have to be smaller. Do you think it might need 2 or 3 more teeth, to make sure it catches the other gear all the time?

All and all, that came out nice! Thanks for sharing. Well done!
