    Guys

    Prepping to build a mash tun.

    False bottom or perforated tube?

    If you're building a cooler mash tun:
    The one I made this past fall it working great. 52 quart coleman extreme with slitted copper piping.
    Getting the copper super clean, removing all the burrs, after slitting it was a chore and finding washers that are not galvenized was challenging, but in the end this thing works great. (Of course, I have nothing to compare to).
    Similar to this concept: http://www.brewersfriend.com/2009/01/29 ... -manifold/

    After building a couple and using others, I love what I have now.
    I started with an 48 qt. Ice Cube. You can find them for $30-$40. I got mine from Lowes a few years ago at the end of the season for $20.
    I picked up the cpvc parts while I was there. Off the top of my head I think you need..
    1- 1/2 x 10'
    5- 1/2 tee
    4- 1/2 elbows
    1- 1/2 male adapter
    1- 1/2 female adapter
    1- 1/2 ball valve
    1- female hose bib fitting
    I made a 4-pipe manifold to fit in the bottom and went through the wall with the 2 adapters. The valve controls the flow out of the tun. All the parts are only dry fit together so cleaning is a snap!
    I drilled a hole in the lid so I can put my thermometer in and I even developed a drilled hole system in the lid so I can fly sparge if I want to.
    It works great and I can get about 28# of grain in it for a pretty big 10 gal batch.
    The square design gives me a taller grain bed on smaller batches.
    Lots of pro's and no cons!
    Good luck.

    Something to think about. If you plan to fly sparge, then you want something that will collect wort efficiently without channeling. A false bottom is best, second being a properly spaced manifold. If you plan to batch sparge, as I do, then it rely doesn't matter, as all wort will be drained. Some systems may drain faster or slower but the outcome is the same. I use a mesh screen from a water supply hose. cheap and easy. think about what you plan to use it for before committing to any expense.

    I did the same as chessking in a 10gallon water cooler, except mine has just a straight piece of the mesh hose. By my testing with water, I end up leaving about 2 cups of liquid behind. I figure if I bend a copper pickup tube to lie flat I could reduce that dead space, but just have not gotten around to it.

    Chessking, and advantage to the loop as opposed to just a straight piece?

    Probably none. Just thought it would cover more area, and seemed like a good idea at the time. Certainly not crucial to the performance.

    Thanks boys

    I think I may start with the less expensive screen/ I can always upgrade to false bottom later

    SPent more time than necessary on this. Tried to build spigot piece by piece. Pain in butt.
    much easier :

    Now I have to find a 10 gal cooler in the dead of the Chicago winter!

    This is the model I used except green.... Doing know if it is more insulated or what.

    I also got a thermometer with 6" probe, drilled a small hole about 8" from bottom, filled it with aquarium silicone and shoved the thermometer through. Much nicer than having to open it up to check temp :)

    Oh yeah if doing the mesh hose make sure your hose clamp is stainless also, I almost got the wrong kind.

    Here are pics of my Mash Tun.
    This mash tun has served me well. It most recently helped me win a gold medal on an Oatmeal Stout in a big competition of 600. :mrgreen:
    Hope this helps.

    Great Thread

    It makes me laugh to think that everyone vicariously goes online and search for deals

    I definitely plan on some type thermometer. I was thinking a probe. Insulate wire with tubing (there are how-to threads out there) and stick probe into mash. Probe can also be used for cooling wort, fermenting etc. ANyone use one?

    http://www.amazon.com/dp/B0019R4HQQ/ref ... 5WMVABLB1V\

    (There are cheaper models)

    One more question - could you use a washing machine hose to create a super-bazooka tube (howitzer?)?

    those cheap ones like that work great until you get the probe too wet, then they stop reading correct, buy extra probes and don't get the joint where the metal stops wet at all
