I just finished building my 45L Igloo Coolbox with Stainless False Bottom its been a fair bit of grinding with an Angle Grinder to make the right shape to fit the moulding of the coolbox, finished off in a few places with some 5/16th beer-line for a snug fit and to fix a corner I took a bit too much off, Its all spaced off the bottom with stainless cap screws. I could have fixed the corner and put Beer-line all round the circumference but had done enough grinding to make-fit.

Some of the tools used:

Drilled out Tank Connector with modified Elbow fitted so it is level with the flat base of the tun thanks to the coolbox moulding where the tap fits:

Stainless Steel Cap Screws used as stand-offs so about 25-30mm up from bottom:

Another Cap Screw in the centre to lift it out with:

Outside with Tank Connector & Ball Valve fitted:

False Bottom Fitted:

I had to give the Perforated stainless a good soak and scrub in Washing Soda to remove all grease that came on it.
I have to say this was easier than cutting and soldering loads of bits of copper pipe… Just needs a test run now! Maybe a BIG beer or a Parti-Gyle brew.
