I want to do my first AG batch this weekend. I bought a keg today from a scrapyard, and wish to turn it into a brew kettle. I am about to go cut the top off, and I know I need a valve on it, but I don't know exactly how to construct the valve for it, and also how to construct the valve for the cooler conversion. Could someone post a parts list for both or just general ideas of what I will need for both the cooler and keg? (and I am wanting to go weldless, and am planning on putting both together tomorrow, so a kit won't work). Any help is greatly appreciated!!!
