@centraflow

Mike, thanks for looking in an elliptical mechanical solution!... doesn't look like an easy thing to do.
Also, have a look at the new attached test 3 video with universal joint. I stopped the weights for you, so you can see the lever drive continues on with no problem.



@mscoffman
Thanks for your analysis of the mechanical actions


@I_ron
That was my hope that it would work with the lower shaft off center but unfortunately it is not enough. See the test video.

Now looking for recommendations on how I can easily convert my top gear so the lever is turned in an elliptical orbit to further test this possibility of being the right thing.

Hi gotoluc,
To create motion elliptical shape, structural mechanics have a following way: two coaxial discs rotate in the opposite direction with the arm length difference, probably easiest done.

I don't know if you would listen to me but i will still say my opinion,
1.you need to get rid of that lace on the 2 weight ,it is lowering the output power
2.the plate is straingt not bend on the 1 weight,don't know why you did that
3.looking from the top down ,the 1 weight is at 12 o clock ,and 2 weight is at 9 o clock,input lever is at center, see video
4.you need a bearing on 1 weight not because you can freely stop top , but because then it need less input power
5.fix lever at gimbal,it will cause less pressure on weights so they will move with less friction

I have been going over the videos and have come to the conclusion that there is a lot going on in the bottom shaft. It was thinking about what he had done for the CV joint that brought it to my attention, that bottom shaft with the tie rods, first at the top connection to the plate and the lack of up and down movement of that plate, I believe it is a stub with a ball end that fits into the shaft which can move in and out "small movement but it is there", in the shaft (could be a tube) there is a socket which the ball end fits into. If you look hard the stub end is a smaller diameter than the shaft where it goes into the plate, those end circular plates with tie rods are retainers for that ball end. The same at the bottom, but I am looking at the moment how the bottom weight is connected and how that is connected to the output drive, though the bottom with a modern CV joint would be no problem for us.


This makes the possibility that, that bottom shaft is in fact a tube, or at least a shaft which has been machined in the end to accomodate a ball ended stub shaft held in there with a spring and that circular end plate, no drive is require at this point, only elliptical movement.


more to come

Except for the fact that CV joints are not built to carry an axial load

That would depend on the CV or swivel  or U being used,, as an example

This is designed  to take a large load :)


Yes that would do nicely.

Update

Spent all day making the elliptical mechanism (part).. still need to fine tune it tomorrow and then I'll give it a test run. Not an easy part to make!   much precision is needed. Parts need to be exact same centers or it jams up.

Hi All,
the mechanical parts need high precision, you will encounter difficulties in the absence of the machine tools needed! . . Things we desire in his garage a small mechanical workshop, as the video of William F Skinner. . .                  :D

Hi everyone,

Don't want to bother you to much this is my first post here. I was interested in this project back on Energetic Forum, but for some reason my account has been banned I get the message - 
"Sorry. The administrator has banned your IP address. To contact the administrator click here"
The click here does nothing that allows me to contact them, so I am completely blocked out.
I know that some people use both forums and since I have no way of contacting them will someone be kind enough to ask Aaron Murakami to investigate what has happened to my account.
I can think of no reason that I should have been banned as I have done nothing wrong there.
I find it very frustrating that there is no way of contacting them.
It may be best to use the same topic forum as this one over on Energetic Forum as Aaron is quite active on it at the moment.
Thanks, and sorry to bother you.

Kind Regards
netica

Hi All,

I don't know what was happening but I am able to log in like normal on Energetic Forum now so thanks anyway.

Hi gotoluc,
will soon succeed.

Not with the mechanism you suggested!... did you know it needs 2 drive gears and going in opposite directions for it to work?... guess I trusted it would adapt to my single gear and didn't realize until 16 hours of building and after I installed it.

Here's the video: https://www.youtube.com/watch?v=-e8jUYrjOAU&feature=youtu.be

I'm going to be taking a break as I've been at this for 13 days straight 12 hours a day.

Hi Luc,

I can see you got into a jam. This design should work (no guarantees) it is a slight modification from my Hyperbolic Drive design, it will produce ellipses and many other interesting permutations from eggs to all form of hypercyclic shapes and patterns, the requirement would be a variable speed on the second sprocket/gear/pulley/directdrive. I have drawn it as a 1/2 speed form, which gives an ellipse, this would be easy to adapt using chains etc. The original Skinner design would be very similar to what I have here. The drawings are quick sketches, just adapt your materials to suite. I hope this helps with your build, regards Arto.
