neo mags

 more to them than meets the eye

   while taking of the old ceramic mags and putting on new neo ones
  i thought i was doing it ok .
   but i wasent.  i had four poles two north two south.
   a round rotor  i put sevan mags back for each pole.  so had 28 in total.
    as thay all  look the same  i just put mags next to each other whare thay wanted to go . like stick to each other  side by side.
   but i thought i had all the north poles up for the new north pole .
   but today after playing with them for a second time i see that only every other is a north then every other a south.  so how can i join sevan small neo mags  together to make just one face the same.
  the small neo mags are 25mm x 10mm x 3mm.
    i want to put 28 on rotor making four poles two south and two north.
   but thay repell each other when i try put the same face up.
  unless i fix them one at a time. with araldite.  
  i know i know nuthing magnets but looks like i need to put sum paint on them so i can find out what gos whare.   like red for south and blue for north.
  its the side bits i cant figuer out  .
     been pulling the mags on and off for hours before i understood that each one wants to be next to a oposit one.  but i want them to all be the same way up.
  i cant beleave that there so strong and picking up every bit of s---  thay can.
  i done wrong smashing the old ceramics off. there everywhare
     i think my fingers are turning magnetic aswell.
    but its all good fun and a great learning curve
  i cant weld them on i cant screw them on  could i use super glue and small clamps.
    but maybe clamp can break them there so brittle.
  i thought all i had to do was let them stick themselves on just to try them on rotor and turn it with hands.
   is that why you need a curved magnet .
 ive lost about six  dont know whare thay have gone. but i did get plenty extra.
     i think i am dreading getting the bigger ones.
     stupid old git aint i .

Hi Blueyonder
 Its not easy mounting simular poles on a rotor close together with glue alone has your finding.I can tell your a hard worker.Remember opposite poles attract.Put one mag on and you should be good to go.So you can wave a mag over the one you placed(i use my fingers has a barrier)If the side you have facing the mag pushes away thats the side you want up.
 I wish you the best and thought you were using curved mags.Maybe a update on the project?

I still don't understand your layout, but you might try the super-glue and get a few of those "finger clamps" with the rubber tips, and glue Every OTHER magnet on slowly.
I had a big problem my first time also trying to glue all 20 mags on the steel disc at once! I put the 20 min epoxy over all 20 holes at once.(Big mistake!)
 Little did I know the magnets would start slidding on the epoxy toward each other like snot! I was able to barely do it, but my fingers hurt for days!  My second rotor, I glued every OTHER magnet on the steel, and it was MUCH easier. Keep at it, ,we sure do live and learn.

I clamped the magnets down with whatever I had
was really glad that I used 90 minute Epoxy

   thanks for helping me understand.
  and thanks for telling me that you guys need to do such things aswell.
   i was getting a bit lost.  so now i know the way to go.
   slowly slowly catch a monkie.   yeh and them neos are little monkies.
   ive put a pic of the rotor here .  but now the ceramic mags have gone and just got the plane steel rotor.
   i need to take my time now and sort out in my mind before i start with super glue
   or epoxy.  
  well the way things are going im happy .
    sumtimes looking for the next idea to do on mill is like searching for a noodle in a hay stack.  anyone can find a needle in a hay stack .(just a big mag you need)
  gluing one down is ok it will be the one next to it that wants to run away.
    ok i got a new job to do now . and i might end up with four poles.
   two north two south. .  so now i can make my plans while i sleep.
         


its a ill wind that dos no good
