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

Don't tell me you've never heard of a differential?!!

do you need the blue tack

author

Yes. It holds the navy rod that it's attached to in place.

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

It wouldn't make sense for it to be locked since that will lock the entire mechanism. One way to put an input on the system is to put gears around the entire differential and rotate the entire mechanism (the cage) around the wheel's axis.

Wikipedia says it better (w/ diagrams): http://en.wikipedia.org/wiki/Differential_(mechanical_device)

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.

I get it now, it's just in some of the steps they're dark grey e.g. step 4. L
