Thanks to FlyGuy and everyone else. The detailed parts list and step by step instructions allowed me to build one of these last night out of a 10 gallon HD water cooler. Time to start planning for my first all grain batch!
On a side note, I had a hard time with sealing off the SS braid so I got creative and bought a small copper pipe cap ( 47¢ ), placed it over the end of the braid and hammered it flat. Works great and weighs the braid down so it doesn't float. Tested with about 3 gallons of 170 degree water with not a leak in sight. Score!
If you use a HD water cooler, follow the advice of several others and buy plenty of washers - I used 5 or 6 on the outside to get everything nice and snug.
Also, another way to secure the hose barb end of the braid that I used was to slip the braid over the barb and wrap around the braid with thin copper wire.
If you look close, you can see the pounded end cap and the copper wire wrap in the picture above.
Thanks again to all - this makes it easy and affordable to start on AG.
