Finished my Mash Tun.
Finished up last week and already did my first all-grain batch(Summer Ale). I had zero problems and everything ran PERFECT. I was concerned about the cooler choice as I hadn't seen anyone use this cooler to date. It is a little big, but I do plan on running some 10+ gallon batches in the future when I upgrade my brew pot. I used a small hacksaw to cut the slits without issue.
No leaks and little to no wort left in the grains. LOVIN' IT!
Thanks to my LHBS and this site it was pretty easy.
