Sgt Chronus magnetic head

Sgt Chronus, the Spear of Macragge, likes to hang out of the tank hatch and point out stuff on the battlefield. He operates under theory that the crew inside can see what the hell he's pointing at out there. His coolest feature, beyond his presence upgrading any tank from 'scary' to 'very scary', is that if the tank blows up he has a chance of being able to put on his powerpack and hop out and turn into an independant character killpoint (with a servo arm (power fist))

He comes soaked in metal Ωltramarine horseshoe symbols that I had to shave off, but that's only part of the problem. The trouble is that he comes with one cool and unique helmety head, one boring bald marine head, and two bodies. Supposedly power armor is the pinnacle of human armor technology, its design has only changed in appearance in some 15,000 years, right? So what is the deal with marines' obsession with running around on apparently perfectly breathable alien battlefields with their helmets off? Hey xenos, witches, and daemons, heres your target right here! It's bald and shiny! Well my army keeps their helmets on, especially cool unique helmets like Chrony's.

I just got my order of Amazingmagnets(.com) today and wanted to put some to the test, so I drilled 1/8" holes in his necks and put in 1/8" x 1/16" magnets.

The trick to magnet placement is that when all glued and assembled, the magnets shouldn't be touching, they should have a slight gap. If they're touching, they act as a pivot and will wobble. If there is a gap the magnet will be pulling tight and holding the piece still, no wobble.

A lot of people at this point would then drill into his head and put a magnet in there too, but that's overkill. I just drilled and put a bit of thick paperclip in there that the magnets love, since the pewter or whatever isn't magnetic at all.

Tadaa! Two Chronusesses with one swappable head! Both of them pointing off into the battlefield inexplicably and perpetually. The head is held snug enough that it won't turn unless you turn it and is easy to take off or turn. That's right, the head turns! It's a damn action figure now! And it was easy and effective enough that you could do this to all your favorite guys if you wanted turnable heads.
