For years now I have been using a round drink cooler for a mash tun and have been unhappy the entire time because it always leaked and warped on the inside. I looked online for a new mash tun and didnt want to spend the money on a blichman, minibrew, or another cooler. I found a 44 quart stainless steel pot that I picked up for a great price and that is almost the exact same size as the drink cooler http://www.amazon.com/Bayou-Classic-.../dp/B000VXHKMC. I cut the threaded top off of the cooler and trimmed the foam from the inside to make the pot fit. I had a welding shop cut the handles off and weld a pipe fitting in the bottom of the pot for me. The pot slides perfectly inside of the trimmed cooler and if I would have lined up the hole a little better it would have been a perfect fit. I am using the same false bottom for the drink cooler in this mash tun. Here are a few pics of what I have done so you guys can check it out.
