And it took me 10 to 15 min to build. I built a proof of concept in 5 min.

It would be good to see this with an input shaft. Are the black cogs on the blue shaft locked on it or "free-wheeling"? L

No it wouldn't make sense for them to be locked, but that's the way they look in 4,5,7,8 & 9. The main picture now shows them as brown with spacers. L

Yes they're brown and are not locked. Please say if there's anything else you don't undestand and i'll try and make the instructions more clear.
