What size false bottom for a Rubbermaid 10-gallon round cooler?

Hmmmm, I think I understand, but I am curious about the pics. It seems like it wouldn't be too hard to just adjust the tun dead space in your calculations though. Making sure the FB stays seated is the tricky part.

Here is an example of what the floor of the cooler would look like if cut in half;

(It's of course a smooth radius and not jagged like in the model)

Interesting...

I have a orange "ribbed" 10 gal. Rubbermaid cooler that has "Gatorade" logo on it and Rubbermaid on the bottom. The top screws on...

I been using it for almost a year with just a screen made from a high pressure water hose.

I want to to switch to a FB to get a higher efficiency since I am in the 50 to 60% range now....

I have noticed in mine what your talking about...it has a slight rise in the middle...I would really like to find a FB that can take advantage of this design...

What did you find out?

I just bought the same cooler the other day. The real model on the bottom says Rubbermaid 1610 got it on sale for 35 at HD. Not putting in any type of manifold or false bottom in it anytime soon. I appreciate the invaluable research though jcraig!

As for the kits with washers I thought I remember reading somewhere that you need to cut the washers down. Oh! It was the easy mash tun 10 gal cooler tutorial on the site...

I haven't tried it out yet but I just got this stainless steel coil spring from a German company called MattMill for my new mash tun project. I hooked it up to a 1/2" ball valve in a 10 gallon igloo cooler. The springs thread into the "T" joint so they are easily removable for cleaning.
