This past summer, I built a pinball lift jack tool. The purpose is to make it easier to setup games on their legs, and/or take them down. Since I was doing a show and setting up and tearing down 8-10 games all in one shot, I needed to find an easier way to do with than past methods I've used. So, I have the lift jack tool a try. In short--it worked pretty well.
I originally saw the design buried in the thread here:

It's a two-piece tool. To set up a game, put the front legs on. Then stick the the frame with the rounded where you would normally use a hand truck, then roll the game onto the floor. Then stick the jack under the frame, and use a drill to jack up the game to the proper height, and put the rear legs on.
To take down a game, put the frame and jack under the game, jack up the game, take off the rear legs. Lower the game to the floor, tip it up, then take off the front legs.
It's fast and the physical effort needed is fairly low.
This isn't my image, but one example I stumbled across from the jeff-z website linked above:
At a later date, I plan to add that hand hole on the frame, and handle on the jack. Otherwise, both are a little awkward to carry around.
