|HOWTO: DIY False Bottom / Mash Filter|
False Bottom / Mash Filter
Yo check this out. I was grinding my grains too fine with a Corona mill and cordless drill, plus I had a stuck mash for the original Big Barrel Brew with 40lbs of grain - Sucked! I've been using rice hulls but is not a good situation when I forget to buy them, so I took Ben Evans idea of using a window screen over his false bottom to prevent clogging and merged it with Wade's hop filter.
Mash Filter Bottom
The two 12 inch 304 Stainless Steel circles were the same size as my false bottom. The SS staples wouldn't work since I didn't have enough extra around the edge and I didn't want to grind down the false bottom. I took a screw and put holes in the outer edge of the circles to line up with the false bottom and some SS wire and started sewing. It took a bit, good project while watching TV (use gloves and a needle nose plier to pull the wire tight).
Mash Filter Threading
The edges are a little sharp so I cut some tubing and wrapped it around the edge to prevent getting poked, I probably didn't need to sew it since the tubing holds it together well. I use a plastic elbow threaded through the false bottom with a small piece of tubing on the back side to hold it in place. This way I can use either my 10gal cooler or Sanke keg depending on how much I'm mashing. (yes don't make fun the top gasket has been replaced since the pic). Cheap simple and easy.
