Rotary Rotation Ratio DEMONSTRATION

There seems to still be some confusion about the relationship between the inside and outside of the Renesis.
Though it is explained often on this site and elsewhere that there is a 3:1 relationship between the eccentric (crank) shaft and the rotors, I still get people coming up with strange math and odd ideas about how many combustion cycles a rotary motor has per rev and what the rotors are doing compared to the "crank"

Here is a video that should explain this in a way the various animations available on the Internet haven't been able to get across.
Hopefully, someone will find this useful.

I see you haven't taken it apart from the other night.
This should clear up any questions on how many RPM's the Rotary is turning.


You did take our red lines off, right? There are spies out there!

The sharpie stuff is mostly gone, but I don't think it can be picked out from that angle.

Well, that guy actually tried to reference those animations as "proof" of his concept. He claims to have built more than 50 13b motors. He should get together with RotaryResurection and compare notes.

It will be interesting to see the back-pedaling that will ensue in that thread...

yeah, that reminds me of the forum expert who proclaimed that the Renesis e-shaft was doing 27,000 rpms at an indicated engine 9000 rpms

That would be awesome!

Those sandals have a steel toe, actually. Comes in handy when the shop temperature is 115°F.

That's not very nice. Wouldn't make me any less correct, either.

Nice clip MM! I too thought I heard some low mumbling.

Must be a mental thing.

Yeah combustion is a chemical process. Having it work at 9,000 RPM rotor, would be amazing. Now, how much heat would that generate?

Obviously, that clip was a bit "targeted". Now that the target has left the building, I'll re-edit it to be a bit more "nice".

if you click on "odd ideas" in MM's original post, it links to the specific post, then above it will say "Thread: <whatever the title is>". just click on that and you get directed to the thread

too bad mod ruined the fun by banning him... would have been more interesting to see how long it takes him to admit defeat... though I guess it's good that kane's thread didnt get taken over.

Not saying the guy didnt deserve a ban of some sort... but even if he is a mod of another forum, he wasnt really trolling (from the looks of his other posts). Didnt look like he had any other posts that were pointless/wrong. Oh well, too late now lol

He was intentionally wrong! Didn't you read his post! He was trying to trick me. He is such a tricky trickster! He got me good.
He was correct on one thing, though - I am spinning that assembly backwards.
Of course, that keeps the rotor coming towards the camera, which is more presentable, but it is still wrong, wrong, wrong!
I should be banned for such trolling!
