Luc,


This is my 900th post... watch out, I'm catching up! LOL


I made many of those talking to our good friend Thane.


I do hope my little contribution here is not taken the wrong way but this linear
motion thing has bothered me from the beginning, anyway, no offence everyone.


Take Care


Ron

Congratulations on you 900th post Ron.

I think I've figured out why Mr. Skinner has reinforcements rods on the lower shaft. I think he arks the shaft and then welded the reinforcements rods so the shaft stays arked. Maybe the effect of gravity with the arked shaft keeps the weight in a more specific area and also no need for a universal joint at the bottom.

Food for thought

Luc that maybe possible, but also I think it maybe to keep out shaft whip, looking at the center disc!!! there is a lot of weight spining around and any whip just might be counter productive ;)

Hi Mike, yes I agree and have previously written it was used for reinforcement but now think it's also be used for creating an ark.
The ark makes sense as it's quite clear the weight of the bottom shaft will always be falling on the outside throughout its rotation.

Adapted the test rig slightly

the smaller weght whips its larger counterpart into action, very interesting startup and recovery sync effects

Thanks Luc,


Here is my take on the gimbal

I don't think the lower shaft need be arked... maybe a hinged type of joint,
then set and forget? (change the square to round)

Hi Ron, that is exactly what is needed.
Luc, Looking forward to your build.
Craig, I like your work ,but that is only half the build, add the lever action to your connection points in the transition plate, then everything changes.
The lever does rotate , but is that because ...it is being driven,...or is just a result of centrifugal force?
Is the only input directed towards moving the levers' back and forth, or also rotating along with back and forth??
The lower shafts have truss kits on them , the same as , grain handeling systems down spouts, they act as a stiffener.
An offset center on the input shaft to the transition plate will create the elptical orbit , that is the key .
Just what I've seen so far...but I'm usually wrong ;D

hi shylo..... i think there are various way of doing this , in my third video i use a linear motion, since i thought it was linear....that might not be how Mr Skinner did it but there was no direct drive, and the input was decoupled from the output. Unlike Mr Skinnner i was tilting the table at 0 degrees and 180 degrees instead of tilting the table for all 360 degrees ... :D

in the last video number 4 i directly drive the shaft with a belt drive....ok this is wrong in that there should not be a rotary transmission right down to the coupler with offset weight. Tis the tilting that would get this to spin normally ,....but many of the effects are displayed even when powered like this.... since the large weight is still decoupled from the system...I see no need to replicate the fancy trousers of the inventor but i do see a need to try all te configurations along the way.. The model is doing all that spinning on around a watt of input its an old tape deck motor.

I will have the gimbals made tomorrow with a bit of luck and will try and get a sony walkman motor to drive it..but this machine is getting too tall

Hi Craigy,

this tests prototype is looking better

Thanks for sharing

Could be Ron... but if that's the case then the shaft could just be bent.

I think the gimbal is exactly right, a really good demo there, from the side view you get the optical illusion.

Thanks Alfilmx and Mike,


Yes, if you look at the unit in the video you can see the four bolts in the end cap and if you look closely
you can see the little dimple in the middle for the axle.


But the proof of the pudding is the visual observation of it working. my slow motion vid and the three seconds where you can see the angles of the shafts and the position of the upper weight as it marches around in a circle. Now the same argument applies to the top driven end of the rod where the shaft
closest to the camera moves seemingly back and forth... then observe the one to the left and it has the same motion. This is only explained if the two are making circles.


Good to see that you are observing and understanding.


Ron

they seem to be moved in pairs 180 degrees to one another. You can see what looks like a beam moving too and frow driven by the motor of course

Hi All, was test running today trying various scenarios' the rotating upper shaft in conjunction with the spinning weights below, cause the upper shaft to pitch to and fro.
I'm sure the motor only rotates the shafts ,  back and forth is just a result, and designed into the build.
I'll know better with more test runs.
