I do not think I have any photos on here of my current set up. Anyway it is a retired maple syrup 45 gal. stainless steel drum, with the bung end cut open and it runs 24/7 year round. I have not had any issues with this set up and I can hang many pieces in there at one time. I do agree with you questioning if it’s going to be deep enough. You can make use the one you are making and get yourself another blue plastic barrel as they are not that costly for larger pieces. You can hang your anodes around the sides similar to what I did, and suspend your iron in the center. Right now I have 3 skillets cooking my current set up.
Take the information from everyones set up and make it work for you.
