Hi all.
Unable to find searching the web, perhaps someone knows what item uses about six inches diameter plastic gears, they may look like this: ----> http://www.tarot-rc.com/images/TL1219-84.jpg
Unsure if I saw something similar in a kid's battery powered ride, or smaller in VCR cam gears, or 120VAC chainsaw, or somewhere else. Then I could look for replacement parts or dumpster diving...
----> Or if anyone has two for sale ?

Re: Looking for large plastic gears...
VCR gears are too small.
A gear box from a large satellite dish pointing mechanism?
Or an old Antenna Rotor might work.
Have you checked the Surplus sites?

Here's one that has a listing of where to get gears for robotic projects.

Just send your gear design to your 3D printer Miguel!
Why plastic? Is that a must? Could you reveal the application?

Thanks, Tzap.
No luck finding such animals; but is not something that I ought to have, so if some day they show up, I may go for them, if the interest of a kid still exists by then.
John: A sort of clumsy kid admires my skills, my workbench, my boredom and my time availability and wants to try the impossible, to build this contraption:

But with shaky hands, I would have to attempt building such only if larger parts are available.
I do not want to go to the point of special ordering anything. He is supplying the magnets, I have a couple of hard drive spindles.

Re: Looking for large plastic gears...
Now that I see what you're building, how about kid's stuff:

Maybe a walk through a Toy's 'R Us and you'd find some big gears suitable for the magnetic motor project.
Have fun!

Perhaps I will wait until he brings the magnets first... No big stores in my location, literarily, neck of bunnyland forest.

Do a CAD drawing and have them laser cut. I can send info on a company I have used.
Generally, if you can draw it they can make it.

That is a perpetual motion machine. These concepts are good for learning. The kid will have to figure out why it doesn't work.Externet wrote:Thanks, Tzap.

Re: Looking for large plastic gears...
You do realize that Monopoles do exist.
http://www.sciencedaily.com/releases/20 ... 103910.htm
But the theory of a magnetic motor is intriguing.
And after viewing some of the video's on YouTube of projects that have been going on for several years.
{Even NASA has been funding a project.}
I can't just easily poo-poo it as just some con artist scam.
But I can see why this would fail because of gear timing, and gauss field parameters,
and magnet placement would be critical to keep it running.
The unit that the Australia company made, requires a microprocessor to act as a type of governor,
to make the slight adjustments to keep it running.

Monopoles... Well, I created a zeropoles magnet years ago. A magnet with no poles
I have no idea what it would be good for ! --- Wound a coil on a ferrite toroid, obtained from a factory of speaker magnets, before magnetized, and zapped with DC. It is a magnet, has no poles. Would you have/think of any use for such contraption ?
The web is filled with hoaxes about those magnet machines, and thousands of hours of tinkering with them.

The machine you made is a Demagnetizer.Externet wrote:Monopoles... Well, I created a zeropoles magnet years ago. A magnet with no poles

They're used mainly for the old analog audio/video heads.
{Audio Cassette Players, or VCRs}
But thanks too Digital CD's, Memory Cards, Ipads, DVR's and other digital storage and playing devices, the need for the demagnetizer has all but dried up now.
There are a lot of hoaxes out there.
But there is a lot of suppression by Big Oil, Coal, and Nuclear to keep new technologies out of the public eye.
