As all newbies, I didn't listen either! I started with a 25 quart cooler, then made the 50 quart, now I am building the 150 quart. The good thing is I have learned so much and have confidence in carrying out the process. I also am building it to stand on end, so I will construct legs/feet to help stability. I will post pictures as I progress, so far I have cut closet shelves to length. Tomorrow I will cut them down to fit completely, I purchased 16 inch deep, so I expect to shape them as the side are not square, the bottom, or back is narrower than the front, and sixteen inches may require shaping the front so as to close the top/door. Also I will post photos as I progress.
