Mash Tun Update
Over Thanksgiving I cut slots in the remaining three pipes for the lauter manifold, and cut and assembled the pieces for the sparge manifold. The long pipes for the sparge manifold will need to be cut a bit shorter, so that it’ll fit in the recess in the cooler’s lid, and I need to find an appropriate way to cut a hole in the lid for the end pipe to stick up through, so I’ll have a way to pour in the sparge water.
The spigot that came in the cooler turned out to simply unscrew, leaving a plain hole; the valve piece I have fits through the hole with only a little space around it, so I’m thinking that just sticking it in there and caulking it around with silicone or something will suffice. My only concern is that this will mean there’s a bit of a gap between one end of the lauter manifold and the floor of the cooler, but I’m not quite sure what to do about that. Probably the answer is “decide it’s not that big a deal,” but even when that’s the right answer, it’s not a very satisfying one, especially if you’ve got something of an engineering bent. But zymurgy isn’t a precise science, except perhaps if you’re Anheuser-Busch, and who wants that?
Finding time to work on the project continues to be a problem.
Mash Tun Progress
On Friday my order of CPVC pipes and fittings arrived, so on Saturday I spent some time working on the mash tun project. I’ve got the lauter manifold mostly done now, and building the sparge manifold will go quicker now that I know what I’m doing a little better. I still have to figure out how the outflow will work, and that’s going to mean actually modifying the cooler itself, so I figure I’m about a third done overall.

Mash Tun Plans
Since I’m planning to make a foray into all-grain brewing, I’m going to need a mash/lauter tun. I’m working mainly from John Palmer’s instructions in his excellent How To Brew (the 1st edition is conveniently available online, and I have the paperback 2nd edition as well), with some planned modifications of my own (I am a homebrewer, after all!).
