I'm trying to figure out how far off the ground the front and back of the cabinets are for WoZ or TH. I've got a TH pre-ordered, and I'd like to be able to lift it by placing a jack under the cabinet at both the front and the back. Since the machine is 350 pounds I don't think I'm going to be able to lift with my back while adjusting it.

We also have some pins at work that are pushed right up against a wall, and I'm not able to lift the back of the machine to adjust them (though I can crawl under just fine).

These are the jacks I'm looking at, any suggestions? Has anyone else ever used a jack for lifting pinball cabinets before? How do you typically lift your machine when adjusting the levelers?

Right now I'm leaning towards the first one since it seems easiest to add some hockey pucks too. I've got wooden flooring, hence I want to add one puck to protect the floor, and one to protect the machine.

24 inch scissor jack (I'd drill hockey pucks to the top and bottom)

30 inch scissor jack (Would again drill hockey pucks to the top and bottom)

30 inch RV jack with a wide base (would add hockey pucks to the bottom, probably throw a towel over the top round base)
