Hi Luc , Wow that's alot of work! The drive I found has to be free to move. You have it locked .I wish I could express myself better.
I think the input only rotates upon its' axis ,while being driven back and forth, the eliptical movement is caused by the rotation of the lower masses which are independent of each other, but push force back at the input , when timed properly can add.
I did some testing today ,I ran a generator off the output for 5 mins, one with the drill connected to the output pulley, the other with the drill connected to my skinner attempt which was connected to the pulley.
They both consumed the same amount of battery life, and the both put out the same amount of watts.
Should the skinner device not use more power since it has those extra gears ,and levers ,and bearings to deal with??
My build is very poor quality ,just trying to see ,but it requires more effort to hold the drill without skinners' apparatus , than it does with it.
I can hold the input (drill) solid or let it follow its' own path , get rid of the sprocket and chains and hold the drive in your hands you'll see what I mean.
I believe there is something here ...artv

Hi Luc,

Just as something to try real quick with that setup,, could you stop the outside short arm piece from rotating while you turn your gear?

If that pivot shaft was solidly connected to the arm and stopped from rotating that would hold that outside arm still and make the oval.

Think about it first,, I would not want you to take up to much time with it,, but it could be run with like a tiller in track maybe.

Hi webby1

I'm away from the workshop for a few days.
It would work a little if there was load on the shaft but don't think anything can be done with it for this device, unless I had a mirror gear.

Thank for trying to help

Luc

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.

Wow!...thank you Artoj for doing all this work

Quite an interesting mechanism. I will study it and see if I can build it with the stuff I have.

Thanks for sharing and taking the time to do all this

Interesting results you're getting

I've already posted a few days back that I disconnected the upper lever drive sprocket and turned it by hand. That's how I concluded elliptical may be the way.

Altho not quite as good as Arto's idea above, if you have zero tools it could be simpler.

Bare bones idea, estimate what you need and adjust with screws to measurements.

Take a tap drill and make a top plate out of some aluminium, that way you can screw in some common sprocket shaft from below, take another and make one underneath.

Screw and add nut and bold adjust. You may need to machine another set of slots for those bolts so that all becomes easily adjustable ( forgot about that )

Print a stencil and drill some plexiglass or w/e material you can get.

I think you can make this pretty low profile and with minimal tools, I think you can make this cheap if you go chinese

If you take small 1/20 hp motor or even smaller, the goal will be to eliminate any useless weight, that way we can approach ideal situation.

What will next step be Gotoluc, this is but a fraction of the whole remember, Skinner aint the type to waste money...

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 gotoluc,
video clip I found: two disks to provide power should rotate in opposite directions, you have reduced the need for complex gear, now you give (part of the disk) is used to keep the lever arm and also is helping to reverse, and it will still work as required..
Well done!
Yes, somehow all available materials to carry out the work it is a top priority because it helps us shorten the time for test machine.

No apology ?

Silence you cretin! As an armchair engineer you are fired!

You wasted master Gotoluc's time.

Hi Artoj,
there are plenty of clips for creating simulated the elliptical motion on youtube and (google) many of them are textured with gears!
Of the mechanical structure in your drawings are very good, there is stability, avoid swinging the arms while working.
 Thank you

Hi ARMCORTEX,
Not true as you think!!!
like myself, do not have conditions to test device! . . A friend of us a lot of effort to do the job too! I think all of us should have the support, albeit spiritual encouragement!. . Step in to test for any device, we will spend a lot of money and effort, it is not easy for everyone to be able to do that! . . From these results bring to a failure or not as desired; we gradually achieve success! . .
I never jealous of anyone!

Hi Luc

I posted the incorrect picture, so I deleted the post , here is the corrected version and another type that maybe even easier to build. The first picture still requires the stationary center shaft, but the second picture shows that the centrifugal action will throw the smaller wheel(pulley/gear/sprocket) around, to ensure that it does, load up some weights on it. Also to stop the vibration you could add a secound wheel on the other side just to balance it. The important ratio is 2:1 of the wheels and 2.666:1 of the pitch center on the smaller wheel to the lower shaft center attachment, I have a few more versions, but I think these should be simple to implement. My Hyperbolic Drive design maybe a little too complex for the type of build you are doing at present, it would be very close to Skinners design, as this has taken me years of work to simplify to this basic outline, which can be used for all sorts of non-linear rotary actions, never underestimate the complexity hidden is some simple arrangements. I hope this helps, regards Arto.

In the pictures it does look like the a belt is around both wheels, this is not a belt, just a doodle showing my ideas and that they are connected , if you did use a belt or chain you would have clearance and use the arm that is above to guide the smaller wheel, or if it was a chain this would be ok as long as there is clearance and maybe wouldn't even need the arm guide, as it is being thrown out clearing the other sprocket. If they were gears then this would be perfect to connect together, as the ratios and smoothness would be superior. Anyway I did this to help out, It isn't the best way to implement the types of gentle actions required to move a rotating lever arm. But as they say let the FORCE be with you, as for me force is not required.  Regards Arto.

Actually if you want a 2:1 ratio, the two gears C1 and C2 will need to be the same size.
