who's design is this?

[dunluce]

I built this off of a thread I found on here, but then I noticed that someone else has an almost identical design a year earlier. Just wondering if there was a HomeDistiller to thank for this, or if it is a design from pre-internet? (mock up just for fitting purposes).

A thumper and a leibig? Old as the hills!

I was looking for something special about it but yep its a still. [emoji16]

I was thinking more along the lines of it being modular, with the ability to change the height of each keg to your taste due to the unions that someone brighter than me must have incorporated into their design.

Just looking to give credit where it is due.

That is a good design for sure.

I hope so. Sacrificial run tomorrow on only the second still I have built, first was my boka.

Looking forward to being able to work with flavours a bit more.

Triclamps are a more recent upgrade vs unions. Faster to set up, variable angles allowed, and no tools required. But even that is old. Its not a new or novel concept, it's common sense.

Do I need a pressure relief valve on this? And if so....any suggestions on what and wear?

[Tummydoc]

Not absolutely critical for a pressure relief (though cant hurt). You're open through the thump to the condensor so should not pressurize significantly. If you run slop in the thumper and have small holes on the thump spear you could clog and pressurize. Some use a pressure relief valve PVR or a manometer as a relief. 5-10 lb PVR would be adequate. You can get brass 1/4 " male thread PVRs on amazon for under $10.

More important is a vacuum relief, especially with your union setup. When you shut down, as the boiler cools you'll create a vacuum and suck contents from the thump into your still. I plumbed a Tee between the kegs and placed a ball valve on the Tee so i can open it on shutdown and relieve/prevent the vacuum. Still requires that i remember. A vaccuum relief valve plumbed on the Tee is my next modification.

You can also crumple the boiler with the vacuum.
That was a classic situation when rain in the woods cooled the boiler and thumper dramatically.

True Geoff, especially with thin gauge copper but unlikely with his Keg system.

Which part? The concentric piping or the hinged lyne arm?

[dunluce]

\Which part? The concentric piping or the hinged lyne arm?

No, not so much the Lyne arm, that's not so brilliant. I was thinking more along the lines of the piping between the begs, allowing them to be placed at different heights, and also the thumper inlet/outlet all contained in one fitting (to me that was brilliant).

[LWTCS]

Sorry, that's what I meant.

Yeah the piping on the risers is just typical concentric piping brought along from Liebig condenser builds.
Not sure who had the first time signature on applying the design to thumpers? Might have been Old Dog?

Kinda the same on the hinged crossover pipe too. Fellers would do that on their Liebigs to allow for different collection jar heights. Again I can't remember who first started doing that?

But both of em been around for a couple few years now.
