Thank you, thank you, thank you...

b-rads are you calling me Tenacious Z?

I think this one will work good because its a legacy device.  Just an alternator with a new configuration and not some fringe science thingy.  I really like fringe science thingys, and have attempted more than a few.  So hopefully this one will turn out better than those...

Thanks again, Y'all... :D

While “Tenacious Z” is more than appropriate, given the superior craftsmanship you exhibit and the spot-on humor in your posts, I am more inclined to call you –
“a m a Z i n g”

I wanted to show a coil profile, first picture...

Then I spent the morning fitting the bearing plates, second picture.  These plates are the mounts for the bearings and axle assemblies.  The Axles hold the Neo-Dia-Mags.  The third picture is the bearing and axle assemblies.  I need to mount the Neo-Dia-Mags on the axles, fit the bearings, and then do the final assembly of the rotating assembly...

So, really getting close...

BTW, Happy Halloween...
Here are some scary vegetables for Halloween....

Mounting the magnets on the shafts.  These are 1 inch diameter N42s.  They are bigger than the other magnets I was using, and considerably stronger.  Its a good idea to get all the steel instruments out of the area when you are working with these magnets.  Especially the sharp, pointy ones.  Don't try and measure the magnets with the steel calipers, you'll wind up stabbing yourself with them.  If you let the magnets get out of control they can slam together and shatter.  There are a lot of caveats to working with these N42s, hopefully the benefits will be worth it...

Drive shaft...

There is zero Z Axis lash on the shaft.  The side to side clearance is a little loose, maybe 2 mils.  So, I am going to pull it apart again, and adjust the bearing plates with a punch to squeeze the bearings a little tighter.  There should not be any movement of the shaft, except the intended movement, spin...

The magnet is slightly motoring on the bearing plate bolts.  Otherwise the magnet moves freely.  It is attracted to the bore equally around its perimeter.  It takes little effort to spin the bare shaft.  This is much better that Diamag 3 with the blocks.  The magnets would motor to the blocks and want to stay there, not very efficient.  This is the eddy currents that we don't want.  I am going to replace the hardware in the core with nylon, or maybe aluminum, and this should eliminate the unwanted eddy currents and motoring.

I'm planning on testing on Thursday.  I have to go gather up some more hardware (can you believe it?), and finish assembly tonight...

Yups...  Me too!

Replaced the steel hardware with brass.  Did the rest of the mechanical assembly.  I got a little over zealous with the socket wrench and cracked one of the bearings.  Also the peripheral magnets do not auto-motor.  I'z already has a contingency plan for this, there are 1 inch shaft extensions on the back side for gears, which are already specified.  All I have to do is make an order.  Then, also, not totally happy with the bearing mount clearances.  So, it may be coming apart again, maybe several times...

So, at least now its more colorful...
