Two Cogs to move shield and overcome sticky
« on: November 29, 2006, 08:18:23 PM »
Another mad idea but thought I would share.

What about two cogs as attached.

The cog on the Right has the usual arc magnet setup, a spiral arc may be better as in some wheels.
The cog on the left has a piece of shielding attached and a magnet that is static and put in place from above on a rig of some sort.

As the Right hand cog turns Clockwise the sticky point will be where the magets get close to the static magnet. as this approaches the left cog turn anti-clockwise and shielding is aligned between the two magnets and overcomes the sticky point at the correct time.

As usual feedback welcome.

Regards

Sean.

Hi Sean,

I think this is an excellent idea (and I have not seen it yet elsewhere).
Of course the thickness of the shield, the distances need very careful tinkering.  Especially in question is the length of the shield because it will not be all the same how long the magnets of the right hand wheel are to attract to it. Hopefully you will be able to test your setup.  Maybe a half-ring shaped magnet on the right hand wheel could also be used?  (I know it is a rare piece in one's drawer...

hi sean,
 I tried that before and it did not work.
  I wish I had some videos to show it but I did not take any.
what hapens is that the "shield gets suck to the none moving magnet and it locks the whole thing up.

Hi Sean,

Nice idea but I have to go with slncspkr on this one. Your magnet would just attract to the shield and get stuck unless you use some method of balancing the forces out (think the Tri-Force technique) www.fdp.nu/free_energy.asp?book=90

Your idea does remind me of a similer one I saw posted somewhere. I posted the picture below.

I can see what you are saying regards the attraction of the shield to the static magnet, but was thinking more along the lines of if the spacing was correct then the neutral line would come into play as discussed by gyulasun in this thread http://www.overunity.com/index.php/topic,1738.20.html

I think I Mill out a couple of Cogs and try some different variations and let you know.

Hi Sean,

If I remember well (it was 3 years ago),  in Wesley Gary's horseshoe setup, the iron piece in front of the two legs of the horseshoe magnet is STILL under attraction, in spite of the fact that it is placed in the so called neutral line! ONLY the iron piece does not show any received magnetism from the horseshoe: this is the unusual fact what Gary noticed.
So the neutral line does not mean the iron piece put there is not attracted but means it remains unmagnetised.  I can check this next Monday when I resume at workplace, though maybe you will have found it by that time.
Sorry if you think this the same way as I wrote above but somehow I read from your previous mail that the iron piece (i.e. shield) placed in the neutral line can be (almost) freely moved, unfortunately this is not really so: this is true in the (narrow) vicinity of the neutral line in front of, above or below of the two legs of the horseshoe magnet.   
And think about when the easiest to get a neutral line: in my understanding it needs both poles of a magnet, the two poles being "guided" in the same plane, the easiest to achive this is to use horseshoe shaped magnets. See also allcanadian's mail in the Adams idea tread on his findings (but he seems to be unaware of the horseshoe shape Gary referred to as giving  the best effect): http://www.overunity.com/index.php/topic,1738.msg18666.html#msg18666

No problems Gyula , after re-reading what you have written I now understand.

I knocked up me cogs today anywayz, ran out of PlexiGlass so used MDF and they came out good.

Have already been trying other configurations out that I was curious about, and I am not much of a reading man, I like to build and learn that way, so it is all good!

Find a picture below of my effort LOL

Regards

Sean.

Hey,

Looking good :-) What size mill do you own?

Hi Jason

I cut these out of one of my own machines I used to sell at http://www.cncdudez.com
It a small desktop Router with milling area of 240mm * 240mm *80mm

(http://www.tekit.seriouslyinternet.com/2006frame-1.jpg)

But having a break from making and selling the units for the last 6 months as busy with work and wanted to have some play time!!!

I have a Bigger machine that is nearly completed that will have a milling area of X-Axis 800mm * Y-Axis 800mm * Z-Axis 200MM

Must admit, never thought I would be using it to do this sort of stuff, but sort of fitted in at the right time!!

Regards

Sean.

Hi Sean,

WOW that looks nice! I've been very interested for a long time in getting muself a mill but the problem is they are waay to expensive and heavy for me to put anywhere. How much were you selling those for?

Hi Jason

One of the reasons I sourced and supplied the desktop machine was as you say the price is ridiculous from most companies and some are way too big for most peoples sheds.
This was just a small desktop version and we aimed it at the hobbist and small business.
We also sold it in kits so people could make it up them selfs and save money.
This meant people could build and own a fully working unit for ?1300.00 which is roughly $2500 USD.

The problem was it was too cheap and we were too busy!, I only made and supplied the machines as a hobby but ended up working every night and every weekend as well as doing my daytime job.

I do plan on picking it up and running with it again oneday, but for now I am enjoying using my spare time to play!!

Regards

Sean.
