MLT Construction Update

Construction of my new 48 quart mash/lauter tun is nearing completion. Here's a line drawing of the design I've employed:

I have drilled 136 holes. On average, that's a hole every ~0.42 inches. I'm hoping this will provide sufficiently uniform outflow to provide a reasonably good extract efficiency. While I think it will provide decent results, I suspect that this design would yield even greater efficiency:

However, I have had no luck finding a 1/2 inch diameter CPVC four-way tee (as would be located at the center of the bottom row of tees). Home Depot has't had them. I called four different local hardware places - nada. I guess I'll just have to make do with what I have for right now. No worries. After all, I still have yet to see what I can squeeze out of the current setup.

I plan to test my new toy later on this week. Here's what I have planned:

Calibration Brew:

10 lbs. Maris Otter
.5 lb. CaraFoam

Centennial @ 60, 10, 5, 1 mins.

Safale S-04

Mash at 153 for 60-75 min.

I'm very interested to see what I can eek out of 10 lbs. of Maris Otter. I can probably expect an OG of 1.045-1.056 in 5 gallons. (Those numbers correlate to 60% and 75% extract efficiency, respectively.)

Lastly, I happened upon this page today. I think this design is pretty clever. Check it out!
