I think it lacks a degree of freedom in this model. https://www.youtube.com/watch?v=jJDCgmtITRs
On the sequence that I selected https://www.youtube.com/watch?featur...IRaJlTD4Y#t=29
in the link can be seen that the longer the long cylinder can rotate about its axis independently with respect to the smaller cylinder.
I think see the angle between the small cylinder and the long cylinder not fixed.﻿

What do you mean it lacks a degree of freedom?

The lower heavier weight rotates around a fixed axis at the bottom. At the top of that shaft connected to the lower weight, it moves in an oval shape. The graph paper diagrams at the end of my video show you 100% the mechanism to translate back and forth oscillating motion to circular motion that causes the top of the shaft to move in an elliptical orbit. The back and forth kicks the upper weight back and forth while the momentum of the upper weight moves in a general circular orbit. As the upper weight moves that "translation" plate (i find it funny someone used that same word here as I do) - that pulls the top of the upper shaft around to FOLLOW the path of the upper weight. The lower weight follows the upper weight.

Again, that diagram I show at the end is the sequence of the mechanism and you can replicate the entire thing by understanding that in addition to knowing how to keep the lower weight shaft moving independently and not in lock step with the input section. With those two thing, you can replicate the entire machine.
