Some people cringe at the idea of BYOB. However, craft beer drinkers and homebrewers love the opportunity to bring their own beer to any party. I have been contemplating the idea of building one of these for some time and put that cooler to use. Here is my DIY cooler kegerator with step by step instructions.
This was a very easy build and only took a few tools and minimal hardware investment. If you already have a kegerator, this DIY cooler kegerator is very cheap to build. Feel free to comment with your own ideas below! Cheers!
RotoZip (Anything that will cut a hole in plastic will do)
Roller Cooler (something with a flat surface area on the lid for your large hole)
Beer Faucet w/Liquid Disconnect
CO2 Tank w/regulator
Pencil or Sharpie
Find the center of your cooler lid and drive a nail. Using a string around the nail, create a 9.75 inch circle just like below. Mark the string 4.875 inches from center. Tie the string around a pencil or Sharpie and make a circle. I recommend 9.75 inches because this will allow both a Corny keg (9″) and a Sixth Barrel (9.25″) room to fit. A sixth barrel will need additional hardware to pour beer.
Trace a spot in the back for your CO2 tank. I have a 5lb tank and it will not fit inside. If you have a 2.5lb tank, you can probably skip this step since it will likely fit inside of the cooler.
Cut out your holes with the Rotozip or saw. Make sure you do this outside and take your time. If your cuts are not even, that is OK. You will be placing insulation around the edges anyways. I have terrible RotoZip skills as you can see.
Trim the pipe insulation to fit around the edges of your cut hole. Sit the keg into the cooler. Lift your lid and add ice. Attach the gas disconnect and the faucet with liquid disconnect. You are now ready to start pouring beer. Since the beer will be traveling such a short distance, adjust the PSI very low.
