I did a google search for homebrew systems using a Rubbermaid cooler as an MLT and found this site. What a great resource! I've been out of brewing for 15 years now (can it be that long?). I had been brewing for a few years before that. My last couple of batches were all grain, and I had even cultured my own yeast from a bottle of Chimay. But I kinda outgrew my system. I've been meaning to get back to it, but.......
Anyway, I'm heading back into it, slowly picking up the pieces I need. I got a couple of 10 gal Rubbermaid coolers and will be following FlyGuy's excellent instructions for building a MLT. Having trouble finding the last part for that (the SS 5/8 fender washer). Need to take an inventory to see where I'm at, but I know I need to get a larger boiling pot (10 gal) and a new chiller.
Good to know you people will be here when I need you.
