Quoted from mbaumle:

How to move a pinball machine alone? Easy:
Look blankly at the game. Play several "last" games on the game. Get the hand truck out, some straps, maybe a blanket. Dig around the toolbox for the one ratchet size that fits the leg bolts, but instead grab one that's *just barely* too small. Throw it back in the tool box, grab another that's *just barely* too large. Dig around some more, and realize that you never put the socket back in the toolbox, and that it's still on the workbench. Look for a chair or barstool that you can stick under the backside of the game while you remove the rear legs. Realize that you threw out that bar stool last month. Look for something else that could work. Call/Text friend to see if they can help. Leave voicemail. Play another game or two while waiting, get tired waiting. Go upstairs from the basement.
Drink a beer and say you'll do it tomorrow.

Quoted from P2K:

Just the breaking down (or putting up) of a pinball machine is a big problem if you are by yourself. The usual way is to use your knee or a chair and lift up the rear of the game and remove the legs then lower the game to the floor.
I tried this in the beginning and will never do again! My back hurt for a long time and eventually I would have permanent back problems.
I have used this system ever since then so I can raise or lower a pin to the floor by myself with no strain. In addition this method is lightweight and small so it can be carried to any kind of location where a pin is and takes up little space in your car.
Thanks.

Quoted from Pinzap:

Great idea but forgive my novice question... but is there a special tool for routing the groove in the edge of the plywood to accept the t-molding?
