Hello! I'm back from a trip to Argentina and I have a glut of videos waiting to go out. First up was the "Are odd-numbered möbius-loop cogs possible?" video which I uploaded a few days ago.

I removed a chunk from the final edit because the scene was making the video too long and was a bit too much of a tangent from the main theme of 'odd cogs'. So I decided to take it out to get to the mobius loop cogs sooner.

But I thought I'd share it anyway! The animations were not completely finished and there is a few mistakes fixed in text: but you get the idea.

More videos out soon. Maybe even today, if the edit gods smile upon me.

Mobius cogs: deleted scene

This is a chunk of my video "Are odd-numbered mobius-loop cogs possible?" which I decided to cut from the final edit. https://www.youtube.com/watch?v=nWQwrU1qUrc This scene was making the video too long and was a bit too much of a tangent from the main theme of 'odd cogs'. So I decided to take it out to get to the mobius loop cogs sooner. But I thought I'd share it anyway! The animations were not completely finished and there is a few mistakes fixed in text: but you get the idea.

The only thing I can imagine right now is if you need to transfer more torque than a single tooth can handle, so you have two paths of cogs to drive another cog. But this isn't really a loop and you would use a sprockets and a chain for that particular case. Maybe Babbage's Differential or Analytical Machines might have a use-case for cogs in a loop?

Planetary gears are sort of looped.. you could probably think of them utilizing an extra dimension as well.

Shredders. Not paper ones, but big industrial shredders designed to destroy some big things, even cars. Some of them will have cog-like blades that are meshing up and additionally (as this connection is not designed to take a lot of torque) they are connected with some normal cogs to an engine. And this creates a loop :)

I've seen displays designed to make a circle of things twirl around which use a loop of cogs.
