Back in the day. I decided that I would build a keg cooler also. Got an old refrigerator. "How old was it????" Well it still had the old latch type handle on it.
The thing worked great. I had it out on my patio. Friends would come over and we'd have a beer or two.
My wife was busy one day. My 3 year old son wanted her to do something. She and he had a little arguement. He went off all mad and crying. After awhile things got quick and she went to check on him. She could not find him any were. Now she is in a panic. "Richard, Richard were are you?" she is calling all through the house. Finally she heard a little voice,"I'm in here"
"where is in here?" "In the beer."
She quickly swung open the door and there he was wedged in the little space between the keg and the evaporator. Less then a foot of room. Fortunately, the gasket were kind of worn and with him pushing against the door gave him enough air to survive.
But I hate the thoughts of what could have happened.
The door came off and the thing went in the dump. It was can beer after that.
Just keep this story in mind if you are designing your own rig and it will be in a garage or basement etc.
Now that is a scary thought! Glad he was OK.
I r the king of the world!...or at least I get to stand on the roof and look down on the rest of yall
