Default False Bottom DIY????

OK I want to go with a false bottom but I can not justify paying more for a mesh screen that sits in the bottom of the keg than for the keg and fittings themselves together.

$100 for a false bottom??? Not happening.

So where can one purchase the materials to make your own false bottom?

That sounds like you'd need some seriously strong industrial equipment. You'll need a sheet of metal of some kind. and then some kind of metal auger/punching tool that will allow you to create a pattern of holes throughout the bottom. Then you'll need to have a welder to weld on a few 'legs' to keep it up off the bottom of the mash tun/boil kettle. Either that or some kind of round metal stretching/press type device to just push the outer ring downward a bit to create the same thing. Add on top of that the need to precisely cut the sheet metal to a round shape exactly the size of your kettle. There may be some pre drilled/punched metal you can buy somewhere but hten you still need to cut it to size and weld on some kinds of legs on the bottom to raise it a small distance off the bottom of the kettle. If you have the tools and know how, by all means, do it and post the pics, we love them

Oh but some people do use something more cost effective, a bit of wire mesh connected to the outlet valve, its not as effective as a false bottom as it has a bit more of a chance to get a stuck sparge, but it still works great, my first cooler style mash tun used one w/ great effectiveness. only one stuck sparge that I recall. My keggle w/ a false bottom is SO much nicer imho :P

Haven't got pictures of mine to hand, but I did something along the lines of this:

...but used a vegetable steamer to save having to drill all the holes:

I don't know how my efficiency compares to other false bottoms, but it seems to work fine and cost around £5!

google online metal suppliers for cheapest possible place. but after you figure in shipping and what not, it might be cheaper to just buy a FB.

Not sure if this is thick enough, but the price is good.

It's the right size perfs, but it's less than 1/32" thick. You'll need something to brace it up.

I would go at least 1/16th thick. From what I can tell, 80% of the cost of a premade FB is the metal itself. Then you have to cut it into a circle.
