I think I found the easiest way to convert a Coleman cooler into a mash tun.
Steps:
1. Take the Spigot Assembly out of the cooler.
2. With a small die grinder, remove the "spigot/valve" part (where you would push the button to drain the cooler)
3. With a 1/8 NPT tap, cut threads into the outside (smaller) portion of modified spigot.
4. With a 3/8 NPT tap, cut threads into the inside (bigger) portion.
5. Thread your favorite pipe thread fittings/valves to the outside of your newly threaded bulkhead fitting. Choose wisely though, I'm not sure how many opportunities you get screwing and unscrewing metal fittings into the plastic.
6. Replace the newly modified fitting into the cooler. Fill with water to check for leaks. I didn't even need to put Teflon tape on the threads, the torque on the brass fittings into the plastic was good enough.
7. Attach your manifold, stainless braided hose or whatever your using as a filter to the inside of the fitting.
Cost: Nothing, although I already had the taps, cooler and fittings laying around the shop.
