I'm planning on building an inmersion chiller for my blichmann fermenter, something like this:http://brewhemoth.com/immersion-chiller
It needs to be small enough to fit through the corny lid, so I can take it out after fermentation.
How can I do it? I don't know if its possible to curve stainless steel tubing that small.
Contact Stainless Brewing. They are a vendor here. http://www.stainlessbrewing.com/
I'm sure you could work up something like this.
What he said... Zach at Stainless Brewing is an AWESOME vendor and already has something worked up like you are asking about. Though, it may not be fully developed for public roll-out yet.
