I've been using a SS braid in my mash tun and it works well but I notice that when I was stirring my mash I was shoving the braid all around and sometimes when I finished a batch and was taking the grain out the braid would be sticking up like Dilberts tie. I had thought of a false bottom for a while but didn't want to cough up the cash. Then I saw a couple of folks DIY false bottoms and I got an idea. I could have the best of both worlds!
So here's my new false bottom. I bought a deep dish aluminum pizza pan on Amazon for $10, drilled a million frick'n holes in it and then cut out a "mouse hole" so it would slip over the top of my braid fitting in the side of the tun. It fits great and if I want a seal around the fitting, I could just pack some cotton in there before I start my mash.
I haven't had a chance to use it yet but I should have a brew day coming up in a couple weeks. I'll let you know how it goes. Meanwhile, let me know what you think!
It looks great!
I'd look into getting that seal so you don't get any grain slipping through on you.
Also, do you know how much dead space that leaves behind in a 10 gallon cooler? I'd love to know for when I try something similar.
