I got bored waiting for my parts for my new build. Rad suggested that may need a cold finger. Don't mind the crude drawings I did them in PowerPoint.
I wanted to make something that required little or no soldering.I looked at the copper that I had and this is what I came up with.

I hope I didn't over or under think this. I would like some feed back if you please.((Okay I lied you do have to solder the 3/4" end cap, depending on what you are building the fins could be optional.)) I also added fins on the 3/4" end cap and i will twist them about 30 degrees to add a swirling affect in the condenser and act like heat sink for better cooling lower in the tube. This is what I'm going to stick it into. http://homedistiller.org/forum/viewtopi ... 87&t=61374

Im still learning.
Thanks ahead of time for your comments

PS it took me a bit to figure out :shock: to convert PDF to JPG then place it on my post. Its much better now.

You'd hearing crickets because no one can figure out what your trying to do. I'm not following your idea, granted I'm not to sharp but I'm lost on this one.

:wtf: Copper scrubbie is pointless, vapor won't even get a chance to reach it with the overkill cooling. How you plan on collecting product?

Seems like we are missing the other 80% of the design.

Is this going on an LM or VM?
