Stewart

From Simreal

AnimStewart is yet another rebuild. The same barrel, the same corpse, but a new 5-element ultrasonic fogger (which is still overwhelmed by outdoor wind), and a nifty new lifting mechanism.

In the old Stewart, I had a tech with a lever (techs are cheap). In the new Stewart, I mounted the body on a drawer slide and ran 1/16" metal cable through a block-and-tackle to a pneumatic cylinder. Most blocks-and-tackle are optimized for strength, slowing down the motion but multiplying the force applied. This one was run in reverse -- taking a short motion at high strength (the cylinder) and turning it into a long, weak pull.

As an added bonus, I routed some of the exhaust pathways from the pneumatics into leaky hoses inside the barrel (well, leaky because I added a spurious t-junction), so Stewart piddles on people as he sinks back down.

Too bad I don't have pictures of the mechanism yet -- and my camera is hiding. I just redid the floors in the house and boy are things a mess!
