Awesome. I was going to be in the market for a False bottom really soon. No point in not trying this first. I have a friend of the family with a plasma cutter. Might give it to him for holes vs slits. I like the tri clamp idea as well.

Great idea and nice work. It will be interesting to see how well it works with your new pump.

Guys, I'm planning an upside down keg for my MLT, "bottom draining" through the sankey opening - Thank you Duckfoot.

My "top" will be smooth and have no hole in the middle so this will be a PERFECT use for it. I am planning on a different lid for my MLT.

Thanks!

benbradford:

In the following picture (http://lh6.ggpht.com/_X55dqN1jdAM/THXIpxyloiI/AAAAAAAAAFU/NWwsApIVJVw/s512/IMG_2285.JPG) you have a copper coil. Is that the return for your mashtun or your whirlpooler for your boil kettle?

Thanks,
Dtrain

This is a picture of my herms coil. It will operate to control the temp of the mash, once my pump is here. Right now it is serving its other purpose as a fixed immersion chiller.

How wide are the slits in the keg? Have you had any problems with grains getting through? Really nice idea.

You might consider nipping the edge to allow complete drainage. I made mine out of a colander and decided to nip the edge so it wouldn't pool around the lip.

I used an angle grinder with a cut off wheel. The slits are as minimal as possible, just enought to push through the keg top. Basically, I would cut until the the blade pushed through the metal, and the cuts were pretty even for cosmetic purposes. I actually had no grain coming through at all. The grain itself kind of makes a filter bed, but even at first, other than the usual thick first runnings, everything was great. I was more worried about a slow flow that grains getting through.

As far as the edges, I felt like that there was never goind to be a seal on the false bottom as is, and some water would move through no matter what. My first brew did leave some wort behind, the dip tube through the stopper is now a little bit lower, but I assume some wort will still be lost. I will adjust beersmith to compensate, and I think that with the efficiency that I recieved (92% final efficiency), I won't worry about losing a half gallon in the mash tun, is no problem.

The parts that i used are as follows:

1/2 inch npt threaded to 1/2 inch compression
6 inches or so of 1/2 inch tubing
1/2 inch to 1/2 inch compression to compression, 90 degree angle
another 2 inch or so of tubing
the stopper
keg top

I hope to build another 6-8 of these and sell them on ebay (not for much, just enought to maybe pay for a new pump!)
