 Even if it spins 1/2 the way and stops and makes the shift. It will do it a little faster each time until it reaches its maximum speed to shift which will be an acceleration. If it doesn't do this you will have to do a time test. But if it does, it is a sign of a proper runner possibility. We sometimes come from different views so people may explain things differently, it doesn't mean we didn't read it, but we often look at things differently as well.

Why would it "do it a little faster each time"? It is not supposed to go "faster each time". It turns slowly, the same speed every half rotation, stops, then the weight returns to the top, trips the release, and turns half a rotation. STOPS, then the weight returns to the top, trips the release, turns half a rotation. STOPS!!!!, then the weight returns to the top, ad infinitum.

Are you one of those speed freaks that thinks something needs to go fast to be effective?
Well if you are, then you will never make a working wheel because speed creates centrifugal force which is exactly what you DON'T want.

Make it run and see how long it runs. I bet you it will stop eventually  This is simple pendulum mechanics. instead of a standard pendulum with a weight swinging from side to side, you made one with a weight oscillating up and down.

haha! brilliant answer just shows you know nothing about what you are actually building. Try reading up on pendulum mechanics and oscillating systems, and you will see what I mean.

What you have is a mass oscillating between two states (top and bottom) under the influence of gravity. hence the "pendulum" effect. Eventually the motion will die out due to friction.

Centrifugal forces is also present on slow wheels, however much lower than a fast spinning wheel. But in return, a slow wheel isn't producing much. It is possible to beat the centrifugal forces at higher speeds, by using mechanical tension on the rotating parts that counterforce the centrifugal force.

Hi ABhammer I saw your video it's very good and it seems to work. It looks like I once designed in the past with an off center in the middle.
I'm not claiming anything here but best regards for that it seems to work.
Thanks for the vid.

Post the .wn2d file please?

Thanks in advanced
