Building an Icebox from Scratch

[wolfenzee]

I am building an icebox from scratch on my boat and could use advice on a few things. I have most of it figured out, type/thickness of insulation and general design. My main question is what is the best way to line it and the "plug" for the door, the actual out side of the door (top load) is a very thick/heavy 3" wood cutting board that extends to the sink. The actual food section is approx 12"x 18" x 16" deep(the block ice is up and behind the food, loaded from the deck). Any suggestions are welcome, I also plan to someday move out of the 19th century and put in some sort of thermo-electric system so am building it to be upgradeable

actually I ended up going with an AC refrigerator/freezer.

We have two lids, one for the freezer and one referigeration, that we made to seal rectangular openings the lids are about 1' wider at the perimeter than the hole with an insulated thicker center with a perimeter about 1/8" less than the opening all around. The lid seats with gravity upon a 1" wide rim of weatherstripping sold in a roll from Home Depot. I took care to miter cut the ends of the seal and fit them well. We pry open the lids freely and frequently so far with little wear. We've had this design for ten years and I have replaced the weatherstripping twice due to wear. Take care and joy, Aythya crew
