Well found I need 2 bearings for the extended axle (a zinc bolt with the head cut off) or else face problems with the connection (via hose, had this issue before when trying coupling with hose).

But the greater annoyance is that for some reason I have not yet established the steel disk is wobbling by several millimeters. (the problem is tiny at the axle but is magnified by the diameter of the disk)

Looks like it's going to be a real pain fixing the latter, easiest solutions I can think of which make a very poor magnetic connection for the disk to the axle. (I could pay you in April/May)

Maybe if I buy more expensive precision nuts.

Or is the bolt bad? (the disk is fine)

SHIPPING WILL BE A BITCH BUT SO IS MUCKING ABOUT?

I very much want to take you up on your offer but am unable to unless I can give you an IOU for it, should be able to swing the shipping costs.

FOR ANYONE WHO IS INTERESTED IN BEING INFORMED;

I HAVE BEEN RESEARCHING THE PRINCIPLES OF HYSTERESIS BRAKE OPERATION AND I FOUND THIS GOOD website http://www.magtrol.com/tensioncontrol/principles.htm

IT TURNS OUT THAT SHORTING THE COILS (INDUCES MAXIMUM COIL CURRENT) AND CREATES MAXIMUM BRAKING EFFECT INSTEAD OF ?RELEASING IT" AS I HAVE BEEN READING LATELY AS AN EXPANATION AS TO WHY MY SYSTEM ACCELERATES WHEN THE COILS ARE SHORTED.

"THE AMOUNT OF BRAKING TORQUE TRANSMITTED BY THE BRAKE IS PROPORTIONAL TO THE AMOUNT OF CURRENT FLOWING THROUGH THE BRAKE COIL. THE DIRECTION OF CURRENT FLOW (POLARITY) IS OF NO CONSEQUENCE TO THE OPERATION OF THE BRAKE." Magtrol Inc U.S.A.

Indeed, in fact by chance i watched a TV program the other day from Discovery in which they showed the magnetic braking system used by roller coasters and they were seeing if it could slow a free fall for emergency evacuations.

All it is is some neo's and some aluminium. (cheaper than copper)
Shorts produce by far the largest Lenz Law effect when outside of your motor gen system.

I'll do the rest by personal message.
