1939 Gravity Power - multiply power by 1200%

[d3x0r]

*sigh*
Got my build mostly done... first day was too wobbly, had to add some supports at the bottom, now the frame is rigid enough...
My drive bar... well I need to reinforce it, the weight on the end makes it flex in the middle, which results in the mass actually at a 0 angle on the main axis.


I found a plate used to make like swivel chairs...

which inside is a wheel on the end of the main shaft, and then attach a crossbar so as the axel turns, it moves the swivel plate, which makes the axis tip... which should make it a self runner   I'm sure it will self destruct as soon as I get all these kinks worked out, since there is no clutching, and it's just a small dimple on the end it's sitting in... already was playing with getting the flex out of the bar and it toppled.  Have to get some patio blocks or something to add some mass to hold the frame down.

I reinforced my pipe with basically a guy wire to the top of the axle and a ways out on the weight shaft... then reconsidered that the flex was actually increasing the angle not decreasing like I had indicated... but, keeping it square is good anyway.


I've been experimenting with this trying to fill in the variables of the math... the length of axle that is below the rod B sticking off determines how much the weight gets raised... the length of rod above B (maybe the total axle length) determines how much force is required to lift m. 


The top swivel plate turns very freely... and it has a wheel that goes around very freely within the ring.  I attached a plate to the top of the axle and used lock washers so it turns exactly with the axle.... I tried various angles and configurations... and if I manually keep the tilt off-center, then the weight falls, and turns the shaft, which freely turns the swivel plate... and if I keep it at a constant(apparent) distance from one of the posts on the plate, then it goes and keeps accelerating... but if I tie it to the plate at the same distance it stops.   Something about equal and opposites... I guess putting the backwards load on the swivel plate means it can't actually go forward...  Even if I tie it so it actually is 90 degrees and a consistent lean... not sure where all the force goes but it doesn't generate rotation.


If I put a lot of pressure inward on the swivel plate it doesn't really turn any more difficult....


Conclusion: a single mass doesn't help.
Adding a second weight with the skinner offset plate... I dunno... could add reactive power as part of the system... otherwise it's just a flywheel... that large skinner machine would certainly store a lot of potential energy....

The top drive is like centraflow drew.
Draw a plumb line from the centre of the gimmble to the center of the upper input pulley.(if the clip loads)
Everything needs to be lined up .
There is a cross bar that joins the 2 inputs ,180 degrees apart.
This connection gives the illusion of an agitator.
The upper shaft that connects to the translation plate is rotating, only because it is connected to the outside of a pulley.

HI ALL THE TOP MECHANISM IS AS PER ATTACHMENT..

[ARMCORTEX]

The elliptical method I have shown in this thread is the best for homemade precision builds.

Good enough is enemy of the best, old engineers think this.

Someguy made a nice build on EF, but his drive seems to have problems.

Seychelles, I dont understand the middle thin chain with the arrows, wtf  do you mean.

Plz add another view and thickness.

Why do you think this is better than individually controlled and electronic feedback ?? You add more more unncecessary mass and longer chains.

How  does this mechanism defeat the property that things seem to slow down and go out of sinch ( since you are faster) when a future toaster is connected.
