Hey DIYPete , I'm thinking of just going the easiest route to make this cooler house some stogies. It maintains 70 degrees very well on its own.
I want to take out those weird looking wire rack shelves they put in ,the wires are too far apart, wavy and can't stack much other than the intended bottles. My original plan was to get some spanish cedar and build simple open top low sided drawers to put ready made cigar boxes on ,but then I thought why couldn't I just put some flat pieces of some sort of plywood on those shelf nubs that are molded into the interior plastic .Some kind of wood that wont put off an aroma I don't want to mingle with tobacco. I have a Menards by me that I think I can get some thin Mahogany ,maple ,cherry wouldn't even impart too much ...or even some 1/4- 3/8 inch luaun and put some perforations in it to allow moisture and air to circulate. Needs to be a stable wood such as what I listed. Anything else I think would swell ,warp or give off a weird aroma over time.
