I found this 70 qt coleman cooler online for a great price. I know it is a little big for 5 gallon batches but it will be great for 10 gallon batches when I'm ready. I made a manifold out of 1/2 id copper pipe. I drilled 3/32 holes in the bottom. I didn't solder all the joints so i could take it apart and clean it. I then removed the spigot and installed a ball valve in it's place.
