I sent Ziggie an email with the link to this thread.  I apologize but it's an old thread that I bumped up so he probably hasn't looked at it in awhile.

To my knowledge he provided instructions via pictures on earlier in this thread. However you have to be familiar with magnets to understand it.

Dr. Geep has a tutorial on magnets at his site.

Hopefully Ziggie will check in soon though.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
