where can you find teh instructions to convert a sanke to a fermenter like you have? id love to check it out
HERE'S A THREAD on fermenting in sankes under pressure.
It's a long thread, so here's a bit of a summary:
1) Get a sanke and appropriate coupler.
2) Modify the coupler kind of like this.
There are several ways to do this, but here are the parts I used:
I got those parts from midwest brewing.
Here are the part numbers for the rest from mcmaster.com

Inside the coupler is a grey plastic piece that functions as a check valve for the gas line. Remove that so you can release gas thru the pressure relief valve.
There is also a check ball that keeps beer from backing into the keg. You'll need to remove it so you can pump beer in.
I bought some snap rings and retaining ring pliers. Just easier to remove than the sanke rings.
I just pump my cooled wort into the sanke thru the beer output of the coupler.
Checkout the thread on fermenting under pressure if you'd like to know more about this process. But fermenting in the sanke is really a terrific upgrade, especially if you do 10 gallon batches. Cheers!
