Three way valve on the top of the vapor supply manifold would let ya pot still or run the column without having to break anything down.

Though that would likely mess up your space saving adjustability.


Thanks! I thought about using a three way valve, but wasn't able to justify an extra $55. Also, think I'd need another valve for the top of the dephleg so that vapor doesn't work it's way down the column as well. I figured it's a balance of form and function, which is why I intentionally didn't add temperature gauges and other add-ons. It might require some additional set-up but I think that's part of the fun.

AL,
Do you have any other pictures of how you created your lid. I'm getting ready to get at this project and I want to mount a 4-inch ferrule within the lid. After that (and of course the internal element port, I plan on fixing the lid to the pot permanently. How did you get the "collar" of copper around the TC flange in this picture:

I'm thinking it may have been this way: How to solder fittings to pots or kegs

Thanks... :mrgreen:

I had a 3" DWV copper pipe that fit over the ferrule. I imagine you could use copper sheet and bend it around your 4" ferrule. I then TIG welded the copper and ferrule together. It took a lot of time cleaning it up and polishing. If you don't have a TIG welder, you can also use special flux and solder. I've had success with tinning flux that you can pick up at the home improvement store.

I then made a copper ring to go over the copper pipe. I drilled a hold in the lid, put the pipe through it and 'tack soldered' it in place so it wouldn't move too much. The hard part is making the triangular gussets to fit on the inside of the lid. I think the lid needs these gussets since there won't be too much solder holding it together where the pipe goes through the lid. Once I made 4 gussets, I heavily soldered everything copper together. I really wish I had taken a picture of the lid, but this drawing might help a little.

Have fun! Can't wait to see how yours turns out!

Thanks Al...

That copper ring gives me a good idea if I mess up my planned attack... :lol:

Just waiting for a few parts and Hopefully, I can get this started/done over the weekend!

Set the still up to try the third configuration - Column Only. Filled the boiler with Birdwatchers sugar wash to do a neutral run. This thing performed like a champ! Solid 94% abv with 35% low wines in the boiler.

My stove is just barely able to supply enough heat to power this thing though. I'm thinking about making an insulation jacket for the boiler....

Just read the whole thread.
Thumbs up ! :thumbup:

I've always been shy to try to tig copper to stainless, but will give a a try sooner or later.
