Blown power resistor

A wire wound resistor failure in a high voltage test system. Current arced from one winding to the next and the sustained arc vaporized wire back up into the encapsulation of the adjacent windings. http://farm8.staticflickr.com/7378/11992133835_544cbb2084_b.jpg A stereo: http://farm6.staticflickr.co...

I'm not getting any stereo effect from this. How did you do it?

No, it's not a cross section of my brain. This is too small for even my brain.

I've been using a cross slide vise. Brings some hefty mass with it as well.
