First go at building pot still

OK, going to bite the bullet and attempt to make my own pot still to go on my T500 boiler. Here's my plan;

The purpose for the join in the column is so I can pack it with botanicals for gin which is what I'll be mainly distilling.

Comments feedback appreciated.

Well first hurdle, apparently 50mm copper pipe doesn't fit inside a 50mm to 20mm reducer 8-}

Or a 50mm ferrule. You need a straight coupler to joing to anything :angry-banghead:

There are codes on fittings some same size some expsnded. Unfortunately i am to cut to remember 8-}

Thanks bluc, I should have known not to assume :o

Ok so ifn you dont have access to an expander, as bluc said, they make these wonderful things called couplers/sockets
These are even local to you

with the 15mm on your plan do you mean dn15 15.88mm or 1/2" 12.7mm ?
Either way the 25mm jacket is a bit big, also get the liebig connectors as close to the ends of the jackets as possible

Thanks Al, I’ll go down to a 20mm jacket then. As for the 50mm yes I know about couplers, as I said wrongly assumed a 50mm to 20mm reducer would connect a 50mm pipe to a 20mm pipe. It’s a bit hard in Melbourne at moment not being able to physically visit the stores.

Looks good doogie. A simple pot opens up your options with what you can make. :handgestures-thumbupleft:
Is your 15mm to 20mm reducer going to be soldered or a union fitting? A union will allow you to move the condenser angle rather than it being fixed and also remove it for cleaning.
Just a thought... id imagine you'd have to be very careful putting botanicals in a 50mm column.. wouldn't want to cause a blockage. I'm not saying dont do it but just be careful not to jam too much in it. :handgestures-thumbupleft:

Hi Dan
The 20mm - 15mm is going to be a push on connection so I can easily remove. On further reflection will probably put the botanicals in the boiler and put bits of orange or grapefruit in the column.

Hi dogie,

That design should work but I’d be looking at a longer condenser to keep your spirit cooler. On a slow gin run it would do the job but would not handle a stripping run without a lot of cool water being thrown at it. Good luck with the build.

Cheers

Thanks Les, what length would you recommend? I do have a T500 condenser that I’m using to make neutral at the moment.

I’ve recently completed two builds and put shotgun condensers on both of them. Your boiler element would be around 2000w so it won’t need too much to keep product cool. I would still build a 2” shotty to enable you to run it flat out on stripping runs. The disadvantage is that it does take a little more time to make than a Liebig.
