I'm planning on going all-grain in the near future. Planning on sacrificing a Coleman Xtreme cooler that I've had for about the last 10 years. Still works great, but doesn't get much use camping anymore because we rarely use something so big since discovering dried food. Not quite sure what the size is off-hand, but I'm going to estimate it's a bit over 10 gallons, and I'll have to mark depths inside soon enough. It's silver, so I'll have to live with the reduced efficiency until I get blue paint, I suppose.
I'm looking at bulkhead kits at Weldlessfittings and Bargainfittings, but it looks like they're all for spigot holes that are 7/8" or smaller. The hole in my cooler is a full inch in diameter, and the wall is 3/4" thick. Any recommendations for a cooler with a larger hole like this?
Alternatively, I've read of people inserting 3/8" vinyl tubing right through the spigot on these coolers. That seems like a viable option, but the tubing slides in pretty easily. Does it really not leak with a bunch of hot liquor or mash sitting on it? I'd love such a simple solution, if it's really viable.
