A slinky is wrong. The fields will be pointing the wrong way. IIUYC.
"IIUYC"??
And then the mechanical design to resist the generated forces. Lots of nubs or a porcupine of braces to the walls.
The slinky is the starting material, not the final product. And when wound into an MPGIcos on it's winding jig it is a self supporting monocoque that needs only be hung by the minimum support to provide against gravity and other externally applied accelerations, and to provide the minimum services (current, cooling...). It works nicely, think about it. You'll catch up!
By the way, remember that I have maintained that the proper MPG needs to be wound in strata that get shifted around the core to create "holey X-Cusps". (Actually, I took to calling those X_MPGs didn't I. This may have added to the confusion. The picture I provided would be the winding for ONE of the several strata.)
THINK ABOUT IT! Why the radius of the CORE? The tape winds up standing RADIAL to the core, strong direction! It is all good, "trust me".
In truth I am not sure the
X_MPGIcos buys us anything over the
X_MPG in that the cusp holes may not be uniformly surrounded like the X_MPG which has two strata on each side. This may lead to problems with the electron retention.
By the bye, The X_MPG is only my second favorite now. I have figured out an equivalent system that is easier to wind!
