Man I've been busy with brewing stuff. After getting the cider racked to secondary I decided that it was time to start gathering the necessary stuff to get going with all grain brewing so I have been putting together a mash tun. I was lucky enough to find a guy selling coolers on Craigslist for pretty cheap so I picked up two for $6. One to make a mash tun and another to use as a cooler. I ended up getting a 48qt Coleman and a 24qt Rubbermaid (both were chest coolers) and I decided to use the larger one for the project. For the manifold I used 1/2" CPVC pipe and a combination of brass and stainless steel hardware (i.e. ball valve, coupler, washers etc.). The cooler I used was an older model so the drain was just a hole with an attached plastic cork on a hinge type thing so I didn't have to remove a valve, or drill any holes. Anyway there's not a whole lot that goes into making one, the most time consuming thing was getting all the parts. So here are a couple pics so you can see how it goes together. Feel free to leave any comments or questions.
