Hi Bill
another dumb techinal question if you don't mind. I attached a PDF file successfully and it can be accessed other it is not showing up on the thread like gurji's original drawing.How can I make that happen?
Thanks
Bizzy

I am sorry but I really have no idea.  I have never tried that.

Something is wrong with your jpg file. Even though it ends with jpg, my editor says it "can't determine type". Seems like you saved in some funny format.

Forgive me for interupting here but maybe I can help.  Simply renaming a file does not convert that file to another type.  Your document is still a pdf even though you renamed it as jpg.  Many freeware utilities can do this for you.  I like PrintKey2000.  Open your pdf in a reader - launch Printkey2000 and capture the area you want in your jpg and save that capture as a jpg.  When you attach this saved file to your post, it will display correctly.  Hope this helps!

You are right about the pdf format. So I just downloaded the file as is. Changed the extension to pdf and opened it. No problem.

I grabbed so the image is here.

But again this will not work. The top is dead center so it cancels itself. The extended side to the right equals the left and bottom being on the other side.

How about if the tubes were tilted down at a slight angle which would have the metal balls rolling down sooner?
Thanks

Here is what I meant by angling the tubes more downward.
Let me know what you think

@Bizzy

No matter how you change the angles, one side will enjoy it, and, the other will hate it. As beneficial as it can be to one side, it will be equally detrimental to the other side.

Try and draw your idea with a real drawing program and once it is done, make a copy and then take that copy and rotate is about 2 degrees. Then draw some straight lines through the center of each shifting weight where they are at their new position. You will eventually see at which degrees the device just fails.

We have all been through this exercise many times.

From what I have learned of these wheels, you would require movements that create at least 5-10 different events for a wheel to have any decent "chance" of turning on its own. That means what? If your wheel has 10 equal sections, then each takes up 36 degrees and in that 36 degrees, at each 3.6 to 6 degrees something has to shift in favor of the direction of rotation. The more events you have, the smaller the shifts that are required to maintain rotation, and the more chance you have of capitalizing on momentum, weight shift, etc.

The less sections you have, the less chances of getting it going. But technically speaking, even if you had 20 sections or more, you have to know in advance that what you are trying is next to impossible, but hey, when did the impossible stop us.

Wattsup maybe you're right regarding those L's cause of it's centre of gravity but what if the horrizontal be a little more heavier so that it tilts a bit down?  ;) Maybe this works.
Regarding Bizzy idea that wheel works too cause it would be like a bessler but with tubes out like in this diagram

Thinking again on those L's yes Wattsup is right cause it always creating balance the L.

I truely appreciate your critique and contructive critisism. I think when I comes down to a working unit it will be a coupling of several ideas.
As I mentioned beforemy wife said we can go shopping this weekend once our wine is bottled so I plan on assembling another test table. I understand it may not work as well as I hope, but is my hope that I can get enough of an understanding to combine this with other ideas I have to get a working unit. I think for this test I will start with two tubes as guruji shows. to see how it reacts. Then add tubes and or adjust tubes to prevent equilibrium.
Again thanks and I'll let you know what progress I make.

I would advise you against it because we have all put in so much time on such wheels and if we can save you some time, then great.

The wheel itself has to be perfectly balanced to start with. Just that can kill any attempt even before you start.

Now take the last drawing. One would look at this and expect it to work. But now turn that wheel so the left tube is at 0 degrees and the right tube is at 180 degree. One is at the top with the ball fallen down dead center, where is the other ball? It is now to the left side of the wheel and working against any further rotation. On such extension ideas, once the angle reaches the bottom at 180 degrees, it passes to the left side sooner then the top can get pass to the right side.

I would suggest you study and study and study as much as possible before you decide to spend money and time on an actual build.

Yes you're right regarding 180 deg but if there are many around the wheel other compensate for that as bessler's.

Good Morning
How many do you think it would take to compenstae for teh others and keep it pout of equilibrium?
Thanks
