Looking for condensing coil

[mealstrom]

Hey all, I'm looking to buy a condensing coil and am curious what they usually go for. I've gone through 2 spools of copper trying to wind my own with no luck. I've done salt, I've done water, I've done water and frozen it, I've built a jig, and I've tried going really, really slowly to let the copper harden back up - all suggestions I've found here. But with no luck.

So, as fun as learning it is, at this point I'd rather spend the money to just get one made right and get my still up and going again, then I'll keep practicing while my still is running.

Here's what I'm looking for (I've attached a PDF with my scribblins too), but suggestions are always welcome if you see a big mistake in what I'm asking for. I am either looking for a double wind condensing coil or a coil with a cold finger. If possible I'd like it to fit in a 1" pipe, but from what I've researched on here that might be damned near impossible, so if need be I could always go up to 2". (Although if we can get it in a 1" I'd be fine with a single coil.)

If anyone has design recommendations I'm happy to take them.

Thanks in advance!

hey there,

simple to build if you have not solved your cooling issue, this fits a 2" column. 1" inner with 3/8 coil, just carry the 3/8 coil past the bottom and solder it back into the bottom cap to make it easier, make it any size you like. Use the 1" pipe as your coil guide.

If you got one or two good single coils out of your attempts, then you can run them into a centre cold finger, like thelegion has done.

On your drawing, the placement of the condenser is a problem. The condenser on a pot still needs to be directly in the vapour output pathway. Maybe I am not understanding what you are trying to do.
