I am going to post pictures of it when I get it finished. It was basically a nice wooden box when I got it, and it had 1 1/2 inch thick styro foam lining the inside. I covered the styro foam with strand board, and painted the strand board, and put 4 layers of sealer on the strand board. I am going to retire my fridge incubator, and go to this incubator. It can hold 2 little giant auto turners. I also have built 2 hatching trays for it. I am using 2 (75 watt) light bulbs for heating, and I am going to put 2 fans in the bottom. I have a nice door with a huge viewing window. I am also going to use a wafer thermostat. It is wired like you would wire a cooler incubator, but instead I am using the wafer thermostat. Foam tape for insulation.
