Yep, now you're thinking, and for triggering the switch, I use a magnetic switch cause it gives a nice clean appearance!

there's one of my dreads, i did a long time back with a light in the barrell and a spinning assault cannon

and heres a Terminator with roughly the same thing!! ![]()
Some Specs on the Dread, I usually use Sprue to span the dreads torso for support and rig everything up to that, since you're making a guy and he's gonna be veiwable through the plastic screen, you should probably make the back engines removeable for batteries and rig the guy and the lights to the front plate and then stick it in there, and wire up the rest from the back!
