My coleman 70 quart extreme copper mash tun

[30Bones]

I run the same cooler and have/had a SS braid. Never liked it.

I sewed up a BIAB bag for it this past weekend hope to try it out real soon. I will mash and batch sparge like I always have. I can tighten up my mill gap and leave it since I also do small batch BIAB on my kitchen stove. Hoping this is a solution and a good option for others if they choose.

Subbed. Looking to make a bigger mash tun. I'm eye'ing the Coleman Xtreme 70QT and going with Copper manifold this time. Thanks for the ideas. I'll be working on this soon.

Looking at next build...

I know this is a old thread but I just used design ideas for my new manifold.
Here is a pic of what I ended up with minus the drain slits and 1 tee..
Does this look like it should be ok?
Also should I slit the 2 pipes that go to the drain? or just stick with the 4 main pipes?

looks awesome.

slit the 4 main ones, then, if you're not in an "aw, EFFIN EFF, more slits" mood, do the remaining 2, but I don't think it would matter much

looks great, wish you many happy brews in it

Thanks for the quick reply GrogNerd,
I have a vertical band saw and was just going to use that...should go kinda fast.
Here is a test slit to see how wide it is.

Main reason I was thinking of not doing the drain line was due to the spacing...
Reading here and Palmers how to would make the spacing off if I slot the middle

 

[GrogNerd]

not 100% sure, but I seem to recall the spacing is not much a concern if you batch sparge, it is if you're fly sparging, when you're more prone to channeling

 

[crashtest22]

Got it.
I usually fly but maybe I will batch a few times and see how it goes

 

[crashtest22]

Just built a fly sparge setup and tested
seems to be working fine.
Had 1/2 gallon dead space though which I thought should be less.
At least I can account for it
second pic is just in re-circulation with star san
also no connections are soldered so able to fully disassemble

just a quick update on this...I have brewed 3 batches in the new tun and its working great. my effency has gone up to measured 79% from lower 70's.
one thing I need to fix/change is the sparge setup. it flows too much if I have it flowing out of all the tubes.
if I turn it down to the run off speed it only comes out of the middle tube. I was playing around and turned the outside tubes to the side and that helped

I batch sparge, so the cheap stainless branded hose works great for me.

I batch sparge, so the cheap stainless branded hose works great for me.

that's exactly the setup I have! lots of draining area an very narrow openings, which drains great but avoids stuck sparges. However, the hose will collapse in a few spots eventually, under the weight of all the grain. Especially if you brew large volume or big beers (like 10 Gallons of 10ABV beer - 30+ lbs of grain). I inserted a stainless steel wire coil inside the hose to keep it from collapsing.

Not to take away from the joy of a DIY project, but does anyone sell a premade manifold?

Either the copper or stainless brake?

Thanks
