Well a good day in the workshop today and getting there, so an update from me

First picture below is a re-hash of the 50mm * 10mm Magnet I am going to use.
I did not like the brass holding setup that I did last weekend, so now have milled out two halves of 8mm polycarbonate to set it in. I will tap out the end and put a thread on the axle.
The width came out at 70mm side to side.



Next I found some Carboard tubing which was 82mm external and 75mm internal. Excellent this will give me a nice close gap for the magnet to coil.
I then milled out two 140mm end caps, this will do two things.
1.) Hold the carboard tube in place while winding and also form a lip.
2.) Leaving base plate on after the winding that will give a nice stand.



I then glued the two end caps to the tube and also milled out some couplers, so I could attach it to the winding machines axle.
I wanted to be able to remove the couplers from the end caps after the coil winding was done, so instead of glueing the couplers I tapped out some holes and used come bolts.



The only thing missing now is how to get the Axle through the carboard, so lathed and threaded some 20mm Perspex bar. I then drill a 8mm hole through to take the 6mm axle.
I will mill out two bearing holders for the end of these rods after it is wound.
I drill some holes in the cardboard tube and the bars screwed in nicely and became rigid as they tightened up.
In the background the middle magnet has been pressed into it's new housing a couple of clamps will hold it tight as the glue dries.



Below you can see the Axle Tubes mounted into the cardboard.



Final picture below is with the TO-BE coil mounted in my home made winding machine.
I have used the parts that I build my milling machines out of.
So top Axis stepper simply turns the axle with TO-BE coil attached and bottom Axis Stepper will move side to side with precision accuracy.
Just have to now make a reel mount for the source wire and a tensioner to feed the wire.



Will spend tomorrow rigging up the steppers to a circuit and writing some code to control it.
Nice thing with the steppers is that I should be able to write the code so the wire gets evenly wrapped around the Perspex Bar as it moves along.

More to come

Regards

Sean.

Hi Newman Machine amazing builders!

@The Initial 'flower pot' constructor...
@The (Very) One, Mramos and others clever manufacturers...
Thank you. Great jobs.

I whish I also had my own sparkling device. But do I absolutely need a flower pot?

@Harti_Berlin: Thanks also for your precious advices.
As I can guess it, you have built a Newman machine with huge windings. My French current supplier does not deliver large insulated copper wire spool. Most of big French compagnies frown upon selling retail or to individuals.
My question is : could you direct me (and others) to a serious German compagny (yes, 'serious' and 'German' is a pleonasm. Is it not?  ) wich could agree to sell a single big coper wire spools (0.5 m/m  and 3 or 5 kg or more for example) and to send such item in France?

Best
