I hope that this post is not regarded as spam.
I have posted this image before and had it on my desktop for the last few weeks.
I realize there must be an obvious fault in this image as there was no response to that posting. But please can someone let me know what is wrong with it (not “it doesn’t work�). I sleep better knowing the answer and may avoid the same mistake again.
I know that A1 and A2 has to be lifted, but by my simple calculations that is possible.
Between A2 an B2 is also a problem which I cannot work out. Once at B2, there should be no more problem, as I can see it. Help please. The answer should be staring me in the face but I cannot see it. EVG

evgwheel,
first off it is not quite clear as to how you have attached the offset inner axle without impeding the black wheel rotation.
Actually to me this is irrelevant; The black outer wheel need not move. It could however be looked upon as a flywheel to store kinetic energy.
What you have here is a complicated version of the well known ramp design, most recent popular version is called Axletree. All ramp version designs usually loose torque by being effected by the ramp which is commonly fixed to the stand or frame and does not turn.
As in most all such designs the inventor attempts to start the lift of weights/ spokes at six o'clock. There is never enough torque to complete the lift. I found better but not fruitful results by starting the ramp or lift by leveling out at 4:30 for a clockwise rotation.
Your design in ways can also be compared to an aircraft radial engine with a fixed crank/journal and the engine rotates on the main bearing, The journal never leaves the three o'clock position and holds an odd number of connecting rods.
I have build a number of wheels using this concept or very similar for forum members who did not have the resources to do it for themselves. I must admit the reason for this is that it looks like a viable idea. unfortunetly the end result has always proved to be a bummer.

re: Need help
Thanks Ralph for your quick response.
It is much appreciated.
The offset axle (with arms) is simular to Black drum axle. I felt that the outer rim has to turn or at least be able to turn to make the Ramp between 6 and 5 o’clock a moveable ramp.
You did give me a way to look at it different, but like all designs we stick to it for a little while until that little light above my head lights up and I say to myself “How stupid, why didn’t I see this before. Thanks Ralph.EVG

re: Need help
I have question.
Does anyone know how an old 8-track tape player can take the tape closest to the hub and wind it on the outside of the tape and not stretch the tape. It seems to contradict geometry.

re: Need help
Here is what I was talking about (picture).......surprised no one has responded. Either I am missing something and the question is very simple or your puzzled like me.

Parden my ignorance, I assume there are two "spools" one taking up the tape the other letting out the tape. If so I see your point: is not one spool turning at a different rate to the other? Yet the speed at the magnetic sensor needs to remain constant I guess. Hmmm, interesting point. Isn't this the same for an audio cassette tape? I think the spools need to be independent, and only one spool has a drive attached to it during play. The speed will change during play though won't it? Just like an audio cassette changes speed as you rewind depending how full one of the spools is...

re: Need help
Doc,
No there is just one wheel....that is what has me puzzled. the tape is pulled from a inside (smaller circumference) and wraped around a larger circumference in a continuous loop....doesn't make cense....o well. Thanks egg I saw the link but am still puzzled.
By the way my wife gave birth to our first baby, of course I will include a photo.

Great looking kid. One word of advice. If you want mutual respect in later life, don’t tell her about Bessler. You just entered a world of real love. EVG
