LOL
I see why. … nothing is free. 
Name change…
The distance of boths sections will make a difference to how fast it goes. (theorized)
The device should remain at a constant speed and not consistently speed up. if it was to do that we would have problems, Black holes and gateways to to the Lynxmotion office would be illegal and also i think jim will have no room for us there. lol
EDIT:
Also the gearing i fear might also interfere with the smoothness of the rotation. thus slowing it down.
You get all worm holy on us and you are more than welcome here.
Jonny,
Several things arising here:
You are right about the gears slowing the device down due to addded friction. I say “added” because everyone seems to be overlooking the air friction which is already there.
Unless of course you are planning to run the system inside a perfect vacuum. I know you have probably mastered the art of creating a perfect vacuum chamber. But such a chamber would have to be perfectly shielded so that you don’t have to contend with friction caused by radiation bombardment from the background layer started by the Big Bang.
In which case DiaLFonZo might be right with his “paddle” idea. Of course that has already been engineered in the form of the ball-weighted variable parallelogram govenors that were added to the throttles of stationary steam engines to keep them from running away. BTW the motion of the weights moving outward at speed increases gave rise to the two phrases “Balls out” and “Balls to the wall.” They are legitimate machinery operator’s phrases. All of you with your minds in the gutter should be ashamed of yourselves.
You don’t need to gear a motor or generator to the device. You could use the spinning part as the rotor in a generator. The shielded vacuum chamber could be the stator. But then you will need to overcome the slowing force of Back EMF which is quite powerful. It is used in dynamic braking of diesel locomotives.
If you solve all of this and build two of these systems, you could create two black holes. The worm-hole between them is known as an Eintein-Rosen bridge, and you could be the first to have one. Just beware of building it near the Greenwich Meridian as its effect on world time keeping is unpredictable.
Robot Dude: I see the makings of the next Lynxmotion contest here. You could have people vying for the title of “Worm Holier Than Thou.” Of course people have been dying for centuries to find another way to become worm holy. 
I learned something today. Balls to the wall is a reference to a centrifical speed governor. Cool!
Second that.
Parts are being made NOW! Yay.
Thanks Ted.
But where are the regulating paddle… where…???
Honestly… I don’t know what you mean regarding the paddle. Lol
what one looks like, how it works, or why even have it.
A picture would be helpful.
I don’t expect this device to spin fast.
There is nothing to slow it down.
I am thinking of paddle that would create friction in the air
Oh yes i know what you mean…
Why would i want to slow it down?
Once i have tested it then we can look at ideas. At the moment i have no idea how fast it will go.
I predict zero rpm will be the top speed! 8)
Yeah my thoughts are close to that. Its more likely to just hold itself in suspension . Lol
We will test this theory early next week when parts arrive. 
If not then i have gained some more fridge magnets. 
lol
fridge magnets lol 
always handy :mrgreen:
Cool video please. How about a fly wheel to sutain momentum
Wow if there was only a way to present these pictures in a repeating way. If you were to put enough pictures in sequence and play them back rapidly, it might actually look like it was moving.
Lol… Im not happy just yet to make a video. Its very smooth rotation is only due to the magnets forcing each other away but eventually it slows down. Then stops.
Mounted the magnets different ways. Some pulling some pushing. Number of magnets etc.
I did not know 3D printers had a Blur setting.
Lol
its as much fun as spinning a coin… 
Thinking… Thinking…
Alternation of the magnet will work. Need to reprint a geared design that works like a differential gear so the magnets swap poles. Back to building my owl…
