Insulation Installation

Time to use the expanding foam to fill the space between the inner and outer liners.  I stuffed a garbage can in the top to keep it round and some foam blocks around the outside to keep things centered.

Next I had to get the spray foam to the bottom of the can somehow.  So I attached a long hose to the nozzle and used a dowel to poke it down to the bottom.  Worked great, and I was able to fill the gap pretty easily.

Here's what it looked like when I was done.  I stuck a keg in there so you can get an idea of the scale.  It's OK that the keg sticks out - the beer is drawn from the bottom, so as long as the lower 18" or so is kept ice cold, we'll get cold beer.
