That is insanely awesome. I recently scrapped my ideas for a toolbox control panel in favor of a square electrical enclosure, but I've always drooled over yours (and a few others). The toolbox is so aesthetically pleasing. Jealous.

Wow...looks fantastic all put together. Love the Tolkien font too - perfect touch for a hobby for both Hobbits and kings.

When & what will be the maiden brew?

I'm the guy resurrecting zombie threads AGAIN. Have you brewed on the system since it's been 'finished'? What has been your efficiency into the fermenter? I know there was a few brew days documented with the simple design, what's the verdict on this one?

I haven't brewer on the new on yet, but it is the exact same process. It will come out to be about 70% the way I run the brewday. I am very consistently at about 70% into the ferementer on the Simple.

What are the limiting factors keeping this system at 70%? I am not an efficiency chaser, but if the you folks on here are at 70% I can assume my efficiency would be around 60% as I am still in the brewing primate stage.

Not necessarily. Many systems have equipment losses (leave wort stuck in the lines), but not sure about BK's system. Many people with cooler tuns and non-automated equipment get 80%+ efficiency. The real trick is having it be consistent - I'd take a consistent 70% versus a sporadic 75-85% any day.

Mostly I am lazy. Ha. I just don't take the time to do a very long fly sparge or to do multiple batch sparges. I just drain into my fermentation bucket while fly sparging onto the grain bed, and runt he whole thing through in maybe 15 minutes. That coupled with the fact that I usually mash pretty thin (at least 1.5 qt/# and more often 2 qt/#) and I end up with 70%.

It would be no problem to get he efficiency higher if you wanted to take the time and effort.

The way I run these systems I don't end up with any equipment loss. I typically lose about 3% of total system efficiency in the trub before draining to kettle. Other than that, efficiency typically breaks down like this:

97% conversion efficiency. I lose about 3% of the theoretical potential still in the grains (this is typical)

78-80% lauter efficiency. That means I get usually about 78% of the available sugars into the kettle. The 20% that are left behind are in the wort left in the kettle on in sugars stuck to grains.

So after lautering I have about 75% potential into the kettle.

After the boil and chilling, I drain through a strainer into my fermenter.

I lose about 3% usually to hops absorption and trub, and a bit is left in the kettle typically.

As you can see, the easy improvement is to do a more thorough job lautering. I just take the fast route, since my time is generally more valuable than the extra two dollars in grain.

As a note, if you do a full fly sparge, or a good double batch sparge, you can bump that lauter efficiency up to 85% or higher very easily.
