Stripping Pot still design help

I've not brewed anything in years, but am gearing up to have another go with lots of Tom paste wash on the bubble.
I have a Boka but want a pot still attachment for stripping runs.. and I have no idea about pot stills or operation.

Boiler is 20L 2kw
This length of stainless pipe screws into my boiler its 75mm diameter and 60cm and figured I could maybe use it to cobble something together.
Currently it necks down to 15mm pipe. I have a load of 10mm microbore on hand. Could I just stick a 15mm 90 bend on and then a reducer to 10mm.
Do I need a condenser on the ouput?

What do I need to be thinking and looking at?

You will need a condenser.
The simplest, with what you have, would be to hook up the stainless to the 10mm as a worm condenser in a bucket of slowly flowing cold water.
Well that is unless you wanted to build an air cooled condenser like mine?

If you have plenty of 10mm hand that's the way to go. For air cooling I think you also need a desk fan and a dustbin as a cowl. It would certainly be an easy build and not use gallons & gallons of cooling water.

Thanks Gentlemen.
With regards to operating procedure for a stripping..
Do I just run the heating element at maximum and collect everything that comes out until it's not alc? Or is there more to it?

That would work. For stripping you really are just 'stripping' the water volume away. The spirit run is where the magic happens

For whisky, I strip to 1%.
For a neutral I strip to around 25%.

Are you doing your neutral spirit run on a pot still?

On a stripping still you are mostly concerned with matching your product condenser capacity to the power input - or often the other way around!!!
If your condenser is the limitation you just need to learn how much power you can use and still have all the vapour condensed.

With the 15 mm / 10 mm option I would definitely fit a 10/15/10 T and use TWO of 10 mm coils or condensers. Doubling the coils in parallel slows down the vapour.

In the past I used this 3 coil worm as a strip condenser in a barrel of water.

No. These days I strip neutral on a pot and spirit run on a reflux.
Just because I built one of each and can do so.
