My old mashtun was showing some signs of wear, so i figured it was time to build a new one! I didn't see any threads on rectangular MT builds, so i figured I would document my project for you guys.
First order of business was to get a cooler, i got a igloo marine 48 qt--$25 (Walmart).
Other parts used:
1/4" Brass nipple X 2.5"
1/4" Brass 90
2- 1/4"X3/8 Hose barb
Misc 1/4" copper pipe fittings

The best part of this build is the simple bulkhead fitting, all you need is a 2.5" nipple and a couple of hose barbs.

All i did was just press the brass nipple into the bulkhead fitting, just heat up the plastic fitting and then press in the nipple. Then I took the bulkhead fitting and put it back into the cooler, using the original washers and locknut.
I had some extra copper pipe laying around, so i used it to make a sparge arm and manifold. I attached the sparge arm to the lid of the cooler to keep it out of the way.

Here is the last pic.
I couldn't see the pictures inline so I rehosted, but I'm on chrome so maybe I'm alone.

The kodakgallery thing still doesn't work for direct linking, at least here.

Photobucket and flickr are the two I use, and I'm happy with both.

I'm thinking about building one of these but don't know what size cooler to purchase. I have never done all-grain, but I will eventually want to be able to do 10 gallon batches. Will the 48qt cooler be large enough to hold all the grain necessary for 10 gallon batches?

Yes, I do 10 gallon batches with this setup. I can get about 25 lbs of grain in a 48 quart, which should be enough for even the biggest beers.

Not to disagree with Reddog, but it will be fine for normal 10 gallon batches but a Barleywine, Old Ale, IIPA and RIS would be out. I used 14lbs of grain for 3.5 gallons of Barleywine so 10 gallons would be 40+ lbs

So if I were doing it again I would get a 70qt

What about a build using a 60 quart igloo cube? 15 gallons to hold plenty of grain for high gravity, and the taller aspect still allows enough depth for small batch sizes.

I just built a 60qt cube mashtun, brewed a 10 gal 8% batch of Black IPA (35 lb grist) and it could have taken more.

I would recommend to go big or stay home. I was using a friends Keggle a few weise ago to do a 10 gallon batch of American IPA.
For the mash in I used 1.5 qts of water per lb of grain, with 34 lbs of grain. So with the 8.5 gallons of water and 34lbs of grain, I was spilling over top of cutout in the keg. Had to draw off a quart or so until grain absorbed the water a bit, then added it back in. Too much for a 15.5 gallon keg so I would go bigger than 60quart if you ever wish to do a 10 gallon high gravity batch.
