chainreactor - self reloading gauss gun

[Paul-R]

You should check out SMOT ramps and Jean Louis Naudin's MEP work.

It's not a machine so the setup displaying the effect should be as simple as possible.
I'm convinced that you can make it self-run in a loop just as well as I can, maybe even better.

Yes, ok, but you seem to avoid showing your solution for bringing back the balls for reloading themselves automatically once they empty from the tube...  
This where I suggested using perhaps the SMOT to fulfill this task in case the kicked out energy of the balls is not sufficient for a return into the tube by themselves.

Thanks

Hi Gaby, I had posted a few years back something simular ,
like such a magnet gun,
but it had at both sides of the magnet 2 or 3 steel balls.
When then the additional ball rolls towards the magnet
with its side sticking steel balls, this rolling steel ball
will be attracted also and the magnet flux switches more to this side,
where the rolling ball comes in..
so the other side of the magnet, where the other balls are sticking
gets less flux in this moment...

Now the rolling ball bangs into the stack and transfer
its attraction acceleration energy through the stack into the
last steelball at the other side,
which, because it also has less flux can easily escape now
accelerated.

This should work now back and forth.

I posted it a few years back,
as a SMOTBOWL,
where the balls went on the sides up the bowl ramp,
so after a few cycles, the ball should be kicked out of the bowl.

But I never had the time to try it.
I am now not at home, but nowadays I have all the components.
When I am back at home, where I have my magnets
and the steelballs, I will finally try it .

Regards, Stefan.

Here is another thread with the same ideas:

http://www.overunity.com/index.php/topic,291.0.html

The SBMOT how I called it, must be modified,
so that an equal number of steel balls is sitting at each side
of the magnets.
Then the steel ball which approaches the stack "switches" the magnet
flux onto this side of the stack and the other side?s last ball
can escape more easily after the hit.

Regards, Stefan.

Hi Stefan and All,

Thanks for bringing up the ideas written/shown earlier, I was not aware of that thread.  Now that I read through all those pages I think pinobot's Vertical Gauss Rifle solution offers itself to be a self-runner, with the following improvements I think:

---the addition of one or two more ring magnets are needed with additional balls
    (see picture by pinobot again:
     http://www.overunity.com/index.php/topic,291.msg1783.html#msg1783 and you
     can see his ring magnet placed at the 9 o'clock position, if one more ring magnet
     is needed to help defeat friction, then it should be placed at the 3 o'clock
     position; if 2 more ring magnets are needed, then one is placed at 5 and the
     second one is placed at 2 o'clock positions)

---to reduce the friction of the balls inside the tube to a minimum possible, I suggest
    using ball bearings INSIDE the tube in the manner a linear bearing is made so that
    the big balls making the bangs to each other would be 'wrapped up' with smaller
    ball bearings embedded in a non-magnetic framework, this way the banging balls
    could nicely be guided inside the tube with a minimum kinetic energy loss. Yes, this
    would make the whole setup more expensive to build, it is sure but friction would
    not kill possible self-running of the balls.

Question arises what this setup would serve for other than demonstrating self-running?  How could it be utilized to make useful work out of it? 
Here would come gaby's hint on using magnetic fields to replace gravity (though it is possible with the usage of linear bearing on the balls the vertical arrangement is not needed because the setup might work in horizontal arrangement too, with three ring magnets). So gaby please do some more brainstorming... 

Thanks,
Gyula
