1939 Gravity Power - multiply power by 1200%

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. . .
