My local HD in Encinitas had them in the Outdoor Garden area. Had about 3 or 4 of them at the time.
 
I noticed both sizes at my local HD in the front on the way out the doors. I have two of these 10-gal Coleman Beverage Coolers. Round may be better, but these work great and are very thick. They also have markings inside for both gallons and liters.

Finally got mine straightened out. The 1.5in nipple was too big for the cooler so I went down to the 785, which is labeled "close." I took that to mean it's the smallest nipple they can make and still have the threads on each side. Then I tested and had a leak so I took the inside washer and bent it with a hammer to better fit the shape of the cooler. No leaks!

I just bought a box of 5/8" SS fender washers (had to buy wholesale). If anybody needs one, just send me a message and I am more than happy to send you one via snail mail.
 
I am trying to put one of these together and am having fits finding the appropriate vinyl tubing and o-ring.
Can't seem to find a heat resistant o-ring. Folks at HD/Lowe's think that a standard o-ring is meant to withstand temps up to ~130F.
Is the standard vinyl tubing in the plumbing isle (listed not for ice makers) the "food grade" tubing that has been referred to here?
The specs state that this tubing is rated for temps up to 175F.
TIA for any input.

You don't need vinyl tubing. That was an old design that caused a lot of problems for some people and I no longer recommend using it.

Regarding the o-ring, any o-ring that can be used on a hot water faucet will do. The ones I bought said high-temp rated on them, but I suspect that most of the o-rings in the plumbing section can be used (just ask if it is 'hot water' safe, and if it is, you are golden).

Cheers! :mug:
 
Thanks for the info, FlyGuy, and thanks for coming up with this design and providing so much support to those of us trying to put together an AG rig.

I saw something about this type of setup having problems if used with an immersion chiller as the cold break will clog the braided line, has anyone had a problem with that?

You're getting your steps mixed up. Your immersion chiller shouldn't be put into the mash. I could see the cold break clogging up a plate chiller, if that's what you meant.
 
I'm trying to do this with a ten gallon Igloo and its not quite working. the nipple fits just so so theres no room for a rubber gasket, and since the nipple has the smooth center area with no threading I cant tighten up from both ends for a clean seal. I bought some DAT silicone sealant and will hopefully get it to work with that.

Another option could be to buy a lot of flat washers for the outside of the cooler to force a tight fit.
 
another qustion is-- how important is it that the nut I am using inside be stainless? Im pretty sure it is but not 100%. I figured i'd do a few batches and look for any color change or corrosion/rusting etc.
 
Cripes, 126 pages! Well, I am going to start going through this but could I ask a simple question, which I'm sure must have been addressed somewhere in here, is there any concerns using such a narrow and deep cooler rather than a more traditional rectangular shaped one? Just seems the grain bed would be quite thick and hard to mix as compared with a regular rectangular cooler.

I've never done all grain yet but I'm trying to get as much info as possible before I give it a shot. I'm leaning toward doing a partial mash first.

Thanks

Yep, just buy lots of flat washers for the outside and crank er' tight! :fro:

If you chose to not use a SS nut or washer on the inside, make sure that it is lead free. For the obvioius reason that lead is poisionous to humans, it is also poisionous to yeast.

Either cooler works. It all depends on what is available to you. Lots of brewers use the rectangular cooler with no ill effects. Just about the only draw back that I can see for using the rectangular cooler is needing more material to make a manifold once you upgrade, and you will, from the braided hose to a slotted manifold.
 
Not sure if this has been mentioned already but I used a silicone baby bottle nipple for the "o-ring" on the inside of a 10 gallon rubbermaid cooler. Simply cut off the nipple part about a 1/4" or so above the flange part. The remaining portion of the nipple fits perfectly into the hole from the inside while the flange fits perfectly against the inside wall of the cooler behind the SS nut. My wife recommended it while I had the cooler sitting on the living room floor trying to figure out how to get the stupid o-ring that came with the kit to work. Sometimes non-beer drinkers have great ideas :)
 
What has everyone used as a thermometer for their this? I want to add one to it but just don't know which is good and will work best.

I am tired of using my little floating one.
 
Good call on the baby bottle nipple. I never would've thought of that.

For the thermometer, I started using a digital food thermometer but then got one of these. I'm sure there is a way to attach a permanent thermometer, but I'm not savvy enough to figure it out.

That is what I would like to use. So no one here has attached a thermometer like people have on metal HLT?


I don't really trust electronic thermometers. Have you tried this guys method? Seems a little sketchy with the bung and what not.

No, I haven't tried it. Here's another kit http://morebeer.com/view_product/17511/102307/6%22_Thermometer_Kit_for_Rubbermaid_Coolers but I haven't tried this one either. It would be handy to have but I am always afraid of drilling more holes into the cooler.

A little on the pricey side but I guess it could work.


That looks nice.

You could add one of these to your 1/2" valve. Add a short nipple to your valve and then screw this on:
http://www.homebrewstuff.com/servlet/the-168/in-dsh-line-thermometer-temperature-monitor/Detail

Wonder how accurate it would be. Plus where does the probe come out? Looks funky in the picture.
 
So that fitting would go before the valve? Cooler wall > this thermometer thing > ball valve (and obvously any fittings in between)?

I think you could use it before the valve or after the valve depending on your purpose. I think the only fitting you would need is an additional nipple. I recirculate with a pump and I use a PID for temp control in my beverage cooler. I'm thinking about putting one between the cooler and the valve. The valve would be pointing downward or sideways. If pointed down, it would help with gravity flow systems.
 
The only thing I don't like about the side mounted thermometer option is the fact that it would stick out inside the cooler and make it difficult to stir the mash. I don't want to worry about bumping into it. I could see how a side mounted thermo would be fine for a rubbermaid HLT...

I think I'm going to buy a 12" thermo and stick it through the lid. I'm not sure if this would extend down far enough for a 5 gallon batch but the only 5 gallon batches I do are high gravity with a ton of grain.

That's the same reason that I never looked into doing one on mine.

It may just reach the top of the mash on a 5 gallon batch in a 10 gallon HD cooler. With my nine inch temp probe :)rockin:) I'm able to get readings from various depths of the mash. When I'm not using the probe I just stick it in the handle of the cooler, so that it is right there anytime I need it.
 
It doesn't say that this is a sale price, but HD has this cooler for $39.96:

http://www.homedepot.com/Outdoors-O...splay?langId=-1&storeId=10051&catalogId=10053

Everywhere else I have looked, this thing is $50+.

John

They always have that cooler for that price. I was eyeing one for a long time hoping it would drop in price from $40. It was about 6 months before I decided to get serious about AG and when I went looking for one, I naturally thought HD was a little high in price. Low and behold, I found that they indeed have the cheapest price for that cooler of almost every place out there and you don't have to pay shipping on it either.
 
You just have to be lucky enough to find one at Home Depot as they don't sell them online. Checked one so far and they were out of them. Seeing as how it's kind of out of cooler season right now, I don't anticipate them getting them in again until maybe spring.

I'm going to try 2 more near my home.

*Edit*

What about this one for those that can't find a cooler locally:

http://www.walmart.com/catalog/product.do?product_id=14550424#ShortReviewTitleBar

97 cents shipping. Can't beat that!
 
looks great. I have used a big cooler in the past, but that looks way easier. Thanks.
 
Looking to start getting into AG brewing and this thread has crossed my MLT building path quite a few times.

However, 128 pages of this and I've only had the time to go through the first 50 or so of them in the past 2 weeks.
Being that this thread started back in '07, I'm sure a lot of good ideas and changes have been made.

Would anyone be so kind as to summarize? or point me to a place where it is summarized in here someplace?

When I made mine, I simply followed the instructions provided on the first several pages. Get the parts and slap it together. Was very easy and I have made many batches since. The only change I made was to use a false bottom instead of a bazooka tube. Just a matter of preference.

Have fun!
 
Same here. I had an Igloo cooler so I didn’t get a good seal. I had to buy more washers and eventually use food grade sealant to finish the job, but the first few pages pretty much show you how.

Just follow the initial post... If you have issues with the SS tube, your LHBS might have a bazooka screen option that you can just screw on.

SS fender washers are really hard to find as well. One of the users on here was generous enough to mail me one.
