3 4" Round x 1" DD Black Powder Coated Steering Shaft U Joint Column Size Column | eBay

Steering U joints are cheap and if you have close junk yard they easy to get. Soak them in a little penetrating oil if bound up.

oh yeah, that's a great idea, too.

You are correct, however for the large axial loads which these devices would develop when using large heavy weights it seems to me that the automotive parts might be appropriate. If you look closely at the hub I posted they are easily mounted on a piece of flat plate steel, and it would not be hard to mount any sprocket that you might need for the drive mechanism directly to the wheel hub.

ATV's (all terrain vehicles) have smaller, lighter, but very strong CV joints. They are much cheaper than automotive joints and can be purchased used at ATV salvage yards.

that's great, artoj, a U-joint for the base, super simple. The main source for u-joints that I know of is from cars. Does anyone know of a source of smaller ones?

Also, a ball joint for the top input lever might be useful.

Thanks! that's the kind of thing we need, cheap and readily available parts!

Here are some car parts that will work for the bottom joint on the output shaft. These type of wheel hubs come commonly with a rotary code sensor. I hope this helps.

Pulley sizes

Here are some more crucial details that is important to replicate Skinners original. The motor is similar design and power to Skinners and was popular in the 1930's. Regards Arto.

cv joint

Automotive cv joints will work as well.

more ideas

Thanks Aaron, great video. Here is more stuff I drew last night. Regards Arto.

Gri, I still don't know what you're really asking.

You have tested the copy-pasting
of posts with overunity's default quotes
from overunity to energeticforum.
And it is visible why the link in pasted quote header
can not be operable.

Now please repeat the same action
with my definite post
1939 Gravity Power - multiply power by 1200% .

If you need a link that goes directly to a post,
use the link to the #x at the top right (not the permalink)
and it will take you directly to a post.

I have implemented the operable link format
for vBulletin forum
in quote headers in this my post.
Unfortunately, this format is not being used BY DEFAULT
and even is not being suggested anywhere on the display -
instead of (or besides) the permalink.

The # link is also bad -
the links operability should have been preserved by the developers
for cases of free moving of the original posts
along different threads,
when the position of the posts will change inside a next thread
and will stop the operability of the links in quotes' headers
because of position number of the original post
having been moved.

bearing

Thanks Aaron, lots of great work, it looks like this will be a goer. Here is some ideas about the lower pivot and engagement to the transfer sprocket. Regards Arto

Also these ideas.

Ok, I see what you're getting at. I just used a bushing type bearing with flange...the bushing doesn't only just let a shaft turn like a bearing but the ones I use can actually pivot. So putting the lever shaft through this kind of bearing, it automatically allows it to have more than just a perpendicular relationship between the shaft and bearing. I'll post a picture later.

Thanks, I got to see some parts of it today. I like the diagrams and graphics here, too. Watching pieces of the video today made the whole thing "click" in my mind. Seems like a rough POC would be easy to put together with stuff I have around here.

I didn't get through the whole video yet, but any chance you measure input vs output?

vdownloader

Aaron, I'd like to replicate this, and it seems within my capabilities to do so. One thing, I know people love videos these days, and seeing videos of things working is awesome, but 30 min+ videos on youtube are not possible for some of us with crappy internet connections or data limits.

Is it possible for someone to give a short synopsis of the video, maybe with a few screen shots to see things in a better format? I'd be willing to do this myself, but I have to watch the video in parts, so it might takes me a few weeks.

Anyway, cool project, looks like it has some promise, I'd like to get it going in an off-grid setup!

I'd recommend getting a program vdownloaded and/or the plugin for firefox for example. Go to the video and you can download just the audio in mp3 for example. That is the only quick solution I have for you but you at least need enough bandwidth for that.
