Thwacker needs a mechanism..
--Looking for a solution to a little design problem. The situation
arises due to a firewood pile that's periodically infested with various crawley vermin, which means that, before a log goes into the fireplace I first pick it off the pile, then throw it onto the ground and watch the little buggers scurry off, then pick it up a second time and take it to the fireplace. What I'm thinking is I'll build a really heavy duty firewood rack out of steel, then build something that lifts one end a foot or so off the ground, then drops it repeatedly, to shake out the unwanted critters. So what I need to figure out is how to build a mechanism that's driven by an electric motor that will lift, say, 400lbs a foot in the air, then let go and do it without falling apart over a loooong winter.
