Default How do you suppose they did this decreasing coupling?

This is a wort chiller used to cool the boil rapidly by circulating cold water when making beer.

How do you suppose they connected the 3/8 copper into the coupling? Drilled 1 or whatever plug and solder?

Ive been thinking of a high performance chiller for a while, and thought of a two coil system using bull tees, but this one is over the top! Runs $120, but Im sure I can make it happen with a fun factor!

Honestly, for only 120$ and the very clean look of it I would just say buy it. I LOVE making stuff but that right there is a pristine item for a good price. How many feet of 3/8" copper is there and what would that alone cost you in materials?

No idea how much 3/8 is in it. Yeah, if you look at it as a job for a customer, $120 is real cheap. You can just see the skill involved!

Id like to make my own though, already have an idea for improving it. I think it would be fun, and have bragging rights with my club.

Thats what Im thinking. Im thinking of as tight of a hole, push the 3/8 in a 1/4 fill it with solder, wrap a wet rag around that joint and solder in the 1/2 copper.

Yep, I did 1/2" copper in a brass plug last year. Customer was ecstatic.
