I just completed my first eBiab build. I could not have done it without the people and resources provided by this site. A special thanks goes out to P-J with supplying so many diagrams that he inadvertently created mine, to the Electric Brewery for inspiration, and everyone else for proving over and over that it CAN be done.

Pot:
60 qt aluminum bayou classic with steamer pot
5500 watt heating element
Ball valve - Bargain Fittings
RTD Temperature sensor

Control Panel:
8.5" x 11" Plastic Tote
Auber 2352 PID
LED Light
50a DPST Light Switch
15a SPST Switch

There are many eBiab builds on this forum, and each one of them provide an insight into the build. I want to pay the community back and post my lessons learned. I hope that I can prove this concept to someone else, and maybe kick them off the fence and into eBiab.

-----------------------------------------------------------------------

I do not have a GFI Breaker. So for safety, I went with the Spa Panel. I used a range plug because as I live in an apartment, I do not always have a dryer, but an electric range is fairly constant.

Lesson Learned: Much to my surprise, the Spa Panel doesn't come with an outlet hole in it! No-one mentions how they mounted the plug into the Spa panel, I just assumed it was already there. Upon asking, the answer was a bi metal hole saw. I bought the 2 1/8" size which turned out to be a fraction too large. If you don't need a perfect cut, than it works just fine. 2" is probably the accurate size, perhaps someone can correct me on this.

Also, due to the stiffness of 8G wire, I'm unsure as to how people are mounting the range outlet securely to the panel, as I can't find a way to possibly put any nuts on the outlet screws, so for the time being, I'm leaving the Spa panel face plate off.

Spa Panel Arrangement:
I can unplug the stove and plug in the Spa panel by reaching behind the drawer that slides out at the bottom then drop the just cord behind the stove:

When making a control panel, I know that I wanted an enclosure with two switches, one for the PID and one for the element. I also wanted an indicator light for the element and an e-stop button. Because I didn't want to pay into the $60 dollar range, I foolishly went with a 6x6x6 metal enclosure.

Size Estimate FAIL:

Lesson Learned: Never underestimate how big of an enclosure you really need. More space if never bad. If in doubt, go two sizes bigger.

Still after the failure of the metal box, I couldn't afford to go with a larger metal enclosure...so...I decided to give a plastic tote a try. Why not? It's naturally insulated, heck of a lot easier to work with, and cheaper to replace if needed due to a cutting error.

I was quite bummed after the failure to assemble the metal enclosure... It took me several days to make the cuts, clean it up, and grind down the edges. So I was pleasantly surprised when the plastic tote only about took 25 minutes to drill all of the holes.

The 25 amp DPST switch was next up on the problem list.

There is no possible way I could solder 10G wire to those tiny posts. So, in one of my many trips to Home Debit, I tried to find a screw small enough to fit through the holes, so I could put a hole terminal on the wire, and bolt them together...but alas, it was smaller than their smallest screw..a 4# metric. An employee very politely told me that I would never be able to use that switch. Instead, he directed me to a DPST Light switch used for heaters...with huge terminal screws I could use 10G wire with ease...for $11. Thank you Home Debit employee!

The brew pot is a whole new monster.

Apart from being absolutely terrifying to drill into a $100+ brew kettle, there were dimension concerns.

There was a significant curve at the bottom of the kettle that would prevent flush mounting of the ball valve and heating element. After checking and re-checking, it looked like I could get a flush mount if I centered everything around 2" off the bottom. Holes drilled, element and valve tentatively placed...and steamer basket now rests on the element/ball valve.

I specifically bought the pot with the steamer basket to use with a large grain bag in with eBiab system. So...

Lesson Learned:

3" Carriage bolts with a couple of nuts and washers make great legs. Height adjustable too!

Next hurdle. With the gang box on, the threads weren't quite long enough for the lock nut to tighten onto the element.

Lesson learned:

Most heating elements have an black o-ring already attached.

I haven't seen a post that addresses this, but in order for the Electric Brewer's method of securing the element to work, the black o-ring must be removed.

Wiring the heating element also proved to be a hurdle. The box was so large it extended past the bottom of the pot, so a single gang box was the answer.

Next step is to fill the pot and check for leaks...and of course, it leaked like a sieve.

Lesson learned:

I have read this tip multiple times and I guess I didn't realize how much so....all the fittings dryed up when I tightened them down...I mean REALLY tightened them down. Again, I say, REALLY tighten them down.

So now, everything is wired up, assembled, and leak checked...the big moment...flip the switch! ...Nothing... *sigh*

*Rummage around the spa panel a minute*

Flip the switch! We have another eBiab, I repeat, we have another eBiab build!
 
I also went with one gang on my kettles. It was "tight" but very doable and makes for a nice finished product. Love the control panel in the clear tote. When I say I built my control panel, people assume that means I hung it on the wall myself. I really think it is interesting to show people the "guts" when they check out your system.

Did you install/build a hoist for the basket, to suspend it above the pot? It seems like most BIAB brewers do.

Great project!
 
Well done!

I sorta like the idea of the clear'ish control panel, sometimes I pop my plastic toolbox open just to make sure nothing is on fire in there (over a year now and no issues of course). That'd be handy!

I will note that I use a thick'ish aluminum pot and I do still have my black washer from the heater element on it, on the outside. My silicon washer is of course inside...a few threads grabbed, lots of tightening as you say. Must just depend on pot thickness and thickness of the outside enclosure.

Welcome to the club!
 
I plan on building some sort of hoist. This project was a rather expensive undertaking because I had no tools...at all prior to starting. So I had to buy a drill, dremel, bits, files, wire stripper, etc etc...so long story short, I don't want to buy a miter saw or hand saw or anything else for a while. So right now, I'm considering buying a step stool to match one I already have then hang a 2x4 between them and hang the basket from that.
 
I pull my bags by hand, my kettle is about chest height on me (the top of it), and use a SS mesh strainer that expands to fit over the kettle opening to hold my bag. Works well except if I go over 13lbs of grain, then it gets rather large and doesn't fit in the strainer nicely. A hoist would be neat but I'd be too worried about the bag ripping now that I've done it this way.
 
Ah ha... That looks like a simple solution. Do you press the grain bag?

I don't really press down on it much, fearing it might cave in the framework of the strainer. I do spin the bag super tight and just keep spinning it tighter and tighter until I can't spin it any more...then spin it two more turns ;) Pushing in the sides of the bag as well, just get every last drop from it.

There's always stuff left of course, but this works fairly well. Big tip though: get some good heat/water proof gloves. Currently still using the classic yellow kitchen gloves but someday I'll upgrade to something with more heat resistance. That wort is HOT!
 
posting to super old thread, but this needs to be said...

+1,000,000 for getting me to pull out my oven drawer to see if I can see the outlet.

I was dreading having to pull out the stove for every brew session to get to the plug, and didn't even think of looking behind the drawer. It pulls right out, and the plug is back there. Not 100% easy to plug/unplug from that position, but a crap ton easier than pulling out the stove. So... +1,000,000 to you!
 
I've actually gotten lazier. I went down to a single 2000w heating element with stove top assistance. The trade off is now I have to dunk sparge... I but my efficiency has improved because of it.
