Introduction: Refrigerator INSULATION

Like many in our group I design and build stuff that may or might not  be a good idea...
I left jugs of water out in the cold and stuck the ice in the refrigerator and the stuff in the freezer melted (the ice was not colder than the ice cream so there was no point in adding ice  there)
This is plan B. ...

Step 1: Tools

These are the tools I thought I would need:  a tape measure, straight edge, square, felt marker, long knife or probe,  a saw, I used  circular saw  with an abrasive  blade.
I   would have used a table saw  with a fence  or a hot wire cutter.
Other saws are too messy.
even on this scale  planning helps

Step 2: As You Can See I Use a Masonry Blade

I scrounged some foam board  & cut it to fill the space on a shelf
Thus, I made the area needing cooled smaller.
I was concerned about blocking the thermostat (I don't  know where  it is). so I left space near the walls
Unless you are going to try the obvious alternative: packing peanuts  in a bag (free, quick, easy) 
the rest of this insrtuctible  is how  one guy cuts foam.

Step 3:

I assumed we could get by  with 2/3 of my Refrigerator  space 
I measured from the lip  of  the shelf to where  the glass ended  on the chance  that air needed to pass behind

the foam I found  was 4" thick  That meant I would need to cut into  it, flip it, and match the cuts.
even though I could fill more space  going  4" wide  stacking blocks  like books , I went  4" high   and stacked  2 high
  I I should have used  a darker marker
be warned the blade gaurd  is spring loaded and will catch and tug  the blade enough to screw-up your cuts
it is the  heat   from   friction  that does the  cutting.  keep moving

As planned, I cut one  side first
then I stuck a  knife  carefully  through  the inside corner  I set the foam on edge and cut   using the slot I had just cut as a guide

Step 4:

although  the knife  left a crater I used  straight edge and  ran a  line  to the kerf

I decided to  limit the blade depth so the blade would not catch  on the edge of the previous cut

Step 5:

You can see the blade caught and drifted.

a refrigerator  is a watermelon & turkey  holder in a world with few  watermelons and turkeys.
most of us live with people  who use the  front of the shelf

Step 6: This Is What Rich Americans Have in Their Refrigerators

There are "rules " to cutting and measuring,  and there are "tricks:" Remember  where on  the  tape  the line should go, and where  on your  mark  would be the place to cut.
a "V" arrow  on the left, center or  right  is the standard  hint mark

if you stop mid- cut, back up a little -- jostle away from the edges before you start again.
I am done.

warning: Try not to drop the knife or the  saw on your  foot
better yet  lock the door  and stay inside.
I really  do want to know if this is  good idea, worth doing, etc.
