1- 90* OR 2- 45*??
Good day all,
I have done a google search and was unable to find the answer to my question.
I found a lot of interesting things, and had an enjoyable 1 1/2 hours of reading, but didn't find where this had been answered. (Please forgive me if this has been covered over and over.)
Pot still design, 2-inch copper riser...
At the top of the riser, for the first 90* bend, which method would you use if the fitting were available to you, and price wasn't a consideration?
1. Just an ordinary 90* fitting?
2. An ordinary 45* fitting to a street 45* fitting. (This would be the shortest distance between the 45* fittings. But a larger radius than option #1)
3. An ordinary 45* fitting to a length of 2 inch, to another ordinary 45* fitting. (This would allow you to spread the overall distance between the 45* fittings to whatever you would like.)
I am aware that I tend to overthink things. I also know that other than the chance of some pooling, there is probably very little actually difference in how this choice would affect the overall product coming out the PC.
I also understand that it is beneficial to taper the reduction of the vapor path as gentle as is practical. I will be going from 2 to 3/4 in several steps.
I really just wanted the opinion of those that have much more experience that I do.
Cheers,
WillieP

Re: 1- 90* OR 2- 45*??
Just ordinary 90s work just fine and allow you to still tune the height at the end of the condenser. Most of the different configurations for the top of a pot still are due to the specific requirements of that still. For example, my stripping pot still head is just 1 90 bend connected to my shotgun condenser because the 2" ferrule that i use is welded in a way that makes the end of my condenser the perfect height for collecting into a large vessel on the ground. For a spirit run, i have a long extension into 2 90 bends as this allows me to easily collect into jars on the bench.

I would use 2 90's with a tri-clamp or union between them to make the angle adjustable.

Two 2” 90°s witha clamp between for me too Acfixer
Reduce down after the second one .

Another option for making liebig hight adjustable is to use a stainless union as in photo below.

I said union for you LOLSaltbush Bill wrote: ↑Wed Jan 08, 2025 9:44 pm Another option for making liebig hight adjustable is to use a stainless union as in photo below.

This is what I did for a small still to run in the house Willie.
35mm from the lid, reduced to 22mm for the condenser.
I seen to remember you wanted to keep things as simple as possible, hopefully the pictures answer your question.

I dropped to 3/4" coming out of the head then soldered in a couple of 90s and a copper union to make mine adjustable. I'm about to redo a lot of this setup and I'm going to a 2" shotgun with a couple of 2" 90s with tri clamp ferrules.

From what I am hearing, any of these options will work, and it's really a matter of personal preference and what will work for each situation.
Sounds like I just need to figure out what will work best for me and stop overthinking it.

The input end of my PC has half of a 1-inch copper union to a 1-inch to 3/4 inch reducer to a 3/4 inch 90. (It's 3/4 vapor path, 1-inch water jacket)
The union at the end will allow me to put it at whatever angle I need it at for collection.
This should mean that I can leave the output of the still head fixed and not need to adjustable.
