Ok. Removed the pa Med column entirely and running a batch of apple juice. 3 4inch bubble plates.

Great 6 hours instead od 8 to 10 on the 3x24 packed colmun heads and tails were very abrupt instead of 1.5 gal i got .75gal but at 75% instead of 55 to 60 once i blend and water it back to 40% i will have more final product let you know about taste later

I like my CM set up, it does well for me. I'm currently replacing my old dephlegmator but a couple design features on mine that might be unusual:
My latest dephlegmator (under construction) is 3/4" x 9" and employs not one, not two but 18 through condensers. Granted the condensers are only 1/8" but I figure 18 of them in a roughly 6 point arrangement will do the job nicely. The PC and RC are separated by a manifold an valve as suggested earlier. I don't employ a centering ring but what I did was sand out the inner rim of the reducer that joins the dephlegmator to the packed section. This allows the bottom of the dephlegmator to insert all the way through the reducer thus directing the reflux away from the sides and more to the center of the packing. With my original set up I was pulling about 94% from a packed area of only approx. 16" hight and I expect with the new dephlegmator I will get the same. The old design had flaws in the dephlegmator water feed so I had to rebuild it. I haven't tried other column designs as of yet so I only know CM but honestly if that's as far as it ever got I'd be happy with it. It gives consistent, quality product that runs off like clockwork, every time.

Yeah, that's probably what I'll have to do. It's just a cheap Craftsman welder and just wire, no gas. I do have a stick welder/generator at work but that might melt what I'm working on. Thanks PP.
Spend the 20 bucks and have it done right least that's what I paid.

Nothing wrong with wireless MIG it's just a hot mess. If you clean up nicely afterward flux core will do just as good a job as gas. That said I would be much happier owning a MIG with GAS.

This is such a great thread for those of us who are trying to figure out how to run a CM column! Thank you PP for taking the time to create this AND for responding to all of our questions in such a positive manner.

With the help of this thread, I feel like I have gained a lot insight into how to drive mine and the results are improving. Thanks again. You are truly THE MAN!!!

I have a question. Does it make sense to add a needle valve between the Liebig and column on my CM still?

Reason I ask is, sometimes when I’m running trying to reach equilibrium at low heat and full cooling water to the column I get product coming out of the Liebig.
My thinking is that I could close off the flow of product to the product condenser and continue with equilibrium.

I need to add that I have a 32" all copper column that has the cooling tubes towards the top in a criss cross pattern just below the connection to the liebig.

And that the cooling water is branched off. One valved line to the liebig and a branch to the column.

As first excuse me for my poor English ... I'm writing from Italy.
I am planning the construction of my first CM still and I was thinking about a coil dephlegmator, maintained at a predetermined temperature T.
So I found in this thread some confirmation on my ideas. Fantastic!
What I see critical is to cool the dephlegmator with cold water, even if inserted in small quantities.
So I'm thinking at a different but simple solution ...
Has anyone ever thought about this possibility?

A recycling circuit with an expansion vessel where I can introduce some cold water, which lowers a bit the temperature of the one that comes out from the dephlegmator?

A circuit which recycle water from the dephlegmator and an expansion vessel and a delivery pipe with a small liebig condenser whose cooling water?
Controlled by a thermostatic valve?

Pass the water through a fan-controlled heat sink?

Regarding the pump, use a cheap drill pump to turn the water slowly?

For my 26 Gallon Boiler and 4" plated column set-up, I use a large plastic drum as a cooling water reservoir so I don't waste water, and I built a radiator core with a fan that I attached to it for cooling the hot return water flowing back to the reservoir tank. I have a submersible fountain pump in the reservoir tank which circulates the water through the still. I split my cooling water feed line into two separate lines. One feeds the Dephlegmator, which is controlled with a needle valve, (coolant enters in the bottom and out the top where I installed the needle valve,) and the other line feeds the condenser's cooling jacket. Each have separate control valves and work independent of each other, which gives me better control of each device. I run the flow in and out of my Dephlegmator sort of backwards, in that my coolant enters it closest to the product flow path, but it eliminates the chance of trapping air in a high spot in the Dephlegmator, which could make it run erratically.
