Default My E-HERMS Brew Rig Thread

Hey guys,

I figured i would post up about some of the progress i have been making on my brew rig. It's going somewhat slow partially due to money and a little due to laziness.

Anyway, I have a rough CAD model made for structural portion as it is designed so far:





That is just part of the work i have been doing. A lot more to come with control panel and stuff. I wanted it to look different than most other rigs, and it ended up looking like a sawhorse. I still think it looks good though.

All of the plumbing will be hard lines with disconnects on the sides and backs of all 3 vessels. That way i can unhook the turnbuckles and tip them forward to rinse them out.

Do you guys think its at a good height? the top of the kegs are at ~ 53"

no those are turnbuckles. i will use them to tighten the kegs down to the crossbar you see in the third pic. they will have quick disconnect pins for when i want to tip the kegs forward.

Why the turnbuckles? Do the platforms really need to be tightened down? A spring loaded pin should be enough to hold them in place, I would think. The turnbuckles strike me as an added bit of complexity for little benefit.

yes, the turnbuckles are over-kill - but aren't most brew rig designs you see on here? i made it that way so that i would have no "slop" in the pinned connection that would allow the keg to wiggle. I figured it would allow me to preload it slightly to eliminate any movement at all.

Maybe im not thinking of the same type of spring loaded pin you are...

I would offset the pivot point towards the front of the vessel, that way you have the weight of the kettle providing some stability. Next I would put a relatively stiff piece of rubber on the cross beam to damp the contact between the two steel pieces. The pin would just hold it in place, just like you've drawn for the turnbuckle end mounts, it doesn't need to be spring loaded (I was thinking of a 'spring plunger'). If you position it right, you could pin it in place with some compression in the rubber, which would prevent movement and vibration. I guess if you want them REALLY stable, the turnbuckle will work for that purpose.
