So I cobbled together a mash tun out of a 48 quart cooler and I was just wondering what some of the pros think of it. I still need to get a barb for the spout so that I can attach a hose. I'm just worried about the screen on the inside not being big enough. Anyway, what do you think? The cooler was $20 at Big Lots. I ripped the guts out of a water supply line and used the stainless mesh for the screen inside. The brass fittings and spout were probably $15 or so.
