Ok, I've been doing extract for a while and want to try all grain. I've gathered 3 American 15.5 kegs. I've looked on line for the weldless valves and such and am not just quite sure what all I need for a basic setup. I will do gravity feed at first probably put it all on a brew bench of sorts and would eventually like to add a small pump. I need a good link on a how to video for a. Beginner setup. I want a hot liquor tank, mash tun, and a boil pot all out of my kegs. Thank you
