Spring Generator Motor on YT.

The spring can be adjusted to have  the cam touch the lever at the bottom only aswell.  Makes no difference!
It acts as expected. flywheel slows down sooner than if it was freewheeling.
Not sure what the guy does in the video but I see no way this thing can work.

Hey Vince

Did you just build that after I posted the thread?

Yes, I built it after you posted. Looked interesting and simple. Had all that junk lying around and it only took 1/2 hour.

Nice work.

Some things I imagine would have to be vital for it to come close to working...

He had bearings on both sides of the flywheel, where this would eliminate the weight of the wheel, of which yours looks nice and heavy, from possible binding of the bearing. If there are 2 like in the vid, one bearing on each side, then there would be less bearing resistance. Like the spring is also pushing up on the crank creating more binding actions on the single bearing.

Like here are 2 vids I did years ago showing that removing the grease from a bearing and applying graphite reduces the friction to a sublime minimal. But still, if they have angular force such as your bearing may have, there will be added resistance to wheel motion.

Then a timed rundown. 2 vids, total run down was 14min and 8 sec from 1000rpm. YT only allowed 10min vids then.

And here is a guy that shows a bearing with just grease cleaned out. Clearly the graphite is a champion.

Then he found my vid and shows his improvement with graphite

The point is, if your ambitious, dont stop there as it may not be definitive that it doesnt work yet.

Another point may be that the spring should be more stout. If you have some stainless strips it will have better spring action if you dont have spring steel strips. Love the crank you did there with the bearing wheel. And the adjustable weight as shown in the vid may help. The spring you have there, if plucked without the wheel, what freq does it ring at? May be faster than the speed of the crank, so far. In his demo, that weight in scale size would be a good chunk on your setup. Just saying that resonance of the spring may be key.

Ive been pondering what I will use If I try this. But great to see that you gave it a go.  Real nice rendering of the device. Just throwing ideas to help improve it. If we get rid of as many losses as possible, then if there is just an inkling of something there, it will show more clearly.

Like if everything was as good as it can be done, even if it didnt work, then tests can be done to see if just the freewheel of the wheel, a rundown, compared to the spring in action is having a positive or negative affect on the wheel. If it runs longer with the spring, then we know we are not done yet.
