I know you've seen this plenty of times, but some new pictures are always fun to look at. I followed this guide (because it was the easiest and cheapest): http://www.donosborn.com/homebrew/mashtun.htm
It was hell trying to get that 3/8" siphon in that hole. It's a 48 quart Rubbermaid cooler.
What it looks like on the other side. It was folded at first but after forcing the tube to make love with the cooler's drain hole for a while, it formed into shape.
Attached the SS braid to the tube w/ the end bent over on itself 3 times to form a seal. Attached 2 clamps on each end.
Closeup of the end sealed by folding over on itself w/ clamp for good measure.
Cut the tube and attached a 3/8" plastic valve to both ends of the siphon tubing (also 3/8") with two clamps on each end.
Tested it and it runs fine. Has an extra quart or so of water that doesn't get sucked up on the bottom. Hopefully the grain will take the place of that to-be wort and it won't be a big issue.
9 dollars for the SS braid,
2-3 dollars for the siphon,
1.50ish for the 3/8" valve,
1 dollar for the clamps.
I got the cooler for free, but I imagine it would cost about 25-35 dollars.
Cheapest mash tun ever. Anyone got any experience/tips with this build?
