Interesting... What diameter was your condenser that did that?

I had a condenser that was too large a diameter.
Stainless.
So I stuck a copper tube down the centre and routed it so the water goes down the inside and the outside; made the Liebig into a Davies condenser.
Don't know how it works because my son-in-law has not assembled it yet!
But you get the idea. Simple but a bit tricky re-routing the water etc.
And the copper is an advantage.

I can usually smell fores before they start from the end of the condenser. I often start thinking i can smell a leak during collection but i realize i left a collection jar open or its my low wines jug residial and not from the still itself

When people tell me I'll regret that in the morning, I sleep till noon.

I believe it’s 2 inches.

I had a similar condenser. Two inch outside, one and a quarter inch inside. Liebig, vapour inside and water outside.
Over four feet long, stainless. I got it free, used to be a pre-cooler; when the cows were milked this and an even longer one
(that I got too) mounted in line with it cooled the milk before it went into the massive refrigerated vat.
Like yours, too large a diameter.
(Of course it was designed to cool liquid not vapour. Not the same.)

So I poked a half-inch copper tube down the centre and changed it to a Davies condenser.
Water inside and outside, vapour in the middle.
A bit of thought needed to set up the fittings but no real problem.
And though I have not yet tried it
(still setting up the change of my 50 litre still from gas to electric and waiting WEEKS for delivery of copper ferrules for part of the change.
Bloody virus.)
I am sure it will be much more efficient. With the advantage of copper on the inside of the vapour path.
Cost twenty-two dollars Australian for the copper tube and there was the cost of some copper fittings.

Holy heck! That's huge for that size. Mine was a 2 inch inside but for an 80 gallon rather than a 50 liter. (Don't worry, I'm legal)
