liebig style attachment to a riser/worm

[dance]

so long story short im using a 2ft riser to a 90' then reduced to a 1/2' 6inch piece then 45' down 1/2inch to a 3/8 worm(15ft). I have a 15foot 1/4inch coil that i bought on accident, could i use that to wrap my piece of 1.2inch down and then if at all slide a piece of copper over all that if at all? My question is would that "liebig" type of addition make a difference. All of this ive described wont be put together till Saturday. Thanks so much again guys.

Are you suggesting wraping a coil of 1/4" tubing over the 1/2" type M and then sliding a copper jacket over the top to make a Liebig? Sure, that would work.

Using 1/4" OD soft copper over a 1/2" ID hard copper pipe (which has an OD of 5/8") would make the diameter of the coil over vapor tube 1.125" diameter. That would be a very tight fit inside a 1" ID type M (hard copper) pipe. And if you were to use 1-1/4" ID hard copper pipe, it would fit loosely...probably too loosely.

A better option would be to use the 1" and flatten the 1/4" tubing so it would fit inside the 1" pipe. I would also solder it to the 1/2" pipe so it looks somewhat like an auger, causing a swirling of the water jacket around the vapor tube.

Some here use 4 gage wire to wrap the vapor tube because it is smaller diameter than the 1/4" copper tubing. But I've used that same tubing before, I just had to flatten it a little to fit.

Good luck building the Liebig. They are more efficient than the worm. Incidently, a 3/8" ID worm is the bare minimum for a worm. And 1/2" ID is recommended. Just be careful when running so you don't get a puke. It could possibly plug your worm catastrophically. We don't want that to happen.
