Is a New False Bottom Necessary?
« on: June 23, 2013, 09:42:42 AM »
I brew with a Sankey mash tun with a false bottom that sits on the transition from the side to bottom.  This results in about 2 gallon beneath the FB, but that doesn't bother me since I drain the tun from the bottom. 

My issue is my free FB is 1/8" holes on 3/16" centers.  Because of the rather large holes I lay a piece of aluminum window screen on the FB to minimize grits being carried through. 

I like the idea of a new domed 12" diameter FB that would sit a little lower, but need to be convinced it is worth the $50, or so, that it will cost.  Any idea what the hole size and spacing is on one of them?

mine is 3/32 on 5/32 center and works great. I crush pretty fine too. Usually takes about a quart vorlauf to set the bed and get clear runnings

Mine is 3/32 too, and works well.

I don't think you need a new false bottom, or the screen you are adding.  Recirculating a bit to clear is normal, and the false bottom should be more about holding up the grain bed than acting as a filter - the grain husks are there for filtering.
